The solution to the given problem is as follows: Given series: $0 + (-1)(x-3)^{2n+1}$. The formula to calculate the radius of convergence is given by:$$R=\lim_{n \to \infty}\left|\frac{a_n}{a_{n+1}}\right|$$, Where $a_n$ represents the nth term of the given series.

Using this formula, we get;$$\begin{aligned}\lim_{n \to \infty}\left|\frac{a_n}{a_{n+1}}\right|&=\lim_{n \to \infty}\left|\frac{(-1)^n(x-3)^{2n+1}}{(-1)^{n+1}(x-3)^{2(n+1)+1}}\right|\\&=\lim_{n \to \infty}\left|\frac{(-1)^n(x-3)^{2n+1}}{(-1)^{n+1}(x-3)^{2n+3}}\right|\\&=\lim_{n \to \infty}\left|\frac{-1}{(x-3)^2}\right|\\&=\frac{1}{(x-3)^2}\end{aligned}$$.

Hence, the radius of convergence is $R=(x-3)^2$.

To find the interval of convergence, we check the endpoints of the interval for convergence. If the series converges for the endpoints, then the series converges on the entire interval.

Substituting $x=0$ in the given series, we get;$$0+(-1)(0-3)^{2n+1}=-3^{2n+1}$$This series alternates between $3^{2n+1}$ and $-3^{2n+1}$, which implies it diverges.

Substituting $x=6$ in the given series, we get;$$0+(-1)(6-3)^{2n+1}=-3^{2n+1}$$.

This series alternates between $3^{2n+1}$ and $-3^{2n+1}$, which implies it diverges.

Therefore, the interval of convergence is $I:(-\infty,0] \cup [6,\infty)$.

The particular integral (Yp) is (-3.5/15) sin(8t) if the second-order differential equation is +49y = 3.5 sin(8t).dt2

To find the particular integral (Yp) of the given second-order differential equation, we can assume a solution of the form

Yp = A sin(8t) + B cos(8t)

Taking the first and second derivatives of Yp with respect to t

Yp' = 8A cos(8t) - 8B sin(8t)

Yp'' = -64A sin(8t) - 64B cos(8t)

Substituting Yp and its derivatives into the original differential equation

-64A sin(8t) - 64B cos(8t) + 49(A sin(8t) + B cos(8t)) = 3.5 sin(8t)

Grouping the terms with sin(8t) and cos(8t)

(-64A + 49A) sin(8t) + (-64B + 49B) cos(8t) = 3.5 sin(8t)

Simplifying:

-15A sin(8t) - 15B cos(8t) = 3.5 sin(8t)

Comparing the coefficients of sin(8t) and cos(8t) on both sides

-15A = 3.5

To find the angle between the vectors u = √5i - 8j and v = √5i + j - 4k, we can use the dot product formula and the magnitudes of the vectors.

The dot product of two vectors u and v is given by:

u · v = |u| |v| cos(θ)

where |u| and |v| are the magnitudes of u and v, respectively, and θ is the angle between the vectors.

First, let's calculate the magnitudes of the vectors:

|u| = √(√5² + (-8)²) = √(5 + 64) = √69

|v| = √(√5² + 1² + (-4)²) = √(5 + 1 + 16) = √22

Now, let's calculate the dot product of u and v:

u · v = (√5)(√5) + (-8)(1) + 0 = 5 - 8 = -3

Substituting the magnitudes and dot product into the dot product formula, we have:

-3 = (√69)(√22) cos(θ)

To find the angle θ, we can rearrange the equation:

cos(θ) = -3 / (√69)(√22)

Using the inverse cosine function, we can find the angle:

θ = arccos(-3 / (√69)(√22))

≈ 124.30° (rounded to the nearest hundredth)

Therefore, the angle between the vectors u = √5i - 8j and v = √5i + j - 4k is approximately 124.30 degrees.

For  the critical points of z = (x2 – 4x) (y2 – 2y)

Local maximums: DNE

Local minimums: (2, 0)

Saddle points: (2, 2)

To find and classify the critical points of the function z = (x^2 – 4x) (y^2 – 2y):

1. Take the partial derivatives of z with respect to x and y:

  ∂z/∂x = 2x(y^2 – 2y) – 4(y^2 – 2y) = 2(y^2 – 2y)(x – 2)

  ∂z/∂y = (x^2 – 4x)(2y – 2) = 2(x^2 – 4x)(y – 1)

2. Set the partial derivatives equal to zero and solve the resulting equations simultaneously to find the critical points:

  2(y^2 – 2y)(x – 2) = 0

  2(x^2 – 4x)(y – 1) = 0

3. The critical points occur when either one or both of the partial derivatives are zero.

  - Setting y^2 – 2y = 0, we get y(y – 2) = 0, which gives us two possibilities: y = 0 and y = 2.

  - Setting x – 2 = 0, we find x = 2.

4. Now we evaluate the function at these critical points to determine their nature.

  - At (x, y) = (2, 0), we have z = (2^2 – 4(2))(0^2 – 2(0)) = 0, which indicates a local minimum.

  - At (x, y) = (2, 2), we have z = (2^2 – 4(2))(2^2 – 2(2)) = 0, which indicates a saddle point.

The different GPA ranges between undergraduate and graduate students can potentially lead to stronger correlations among graduate students compared to undergraduate students due to the narrower range and higher academic requirements in the graduate student group.

The different ranges of GPAs between undergraduate and graduate students can have an impact on the correlations calculated within each group.

Firstly, it is important to understand that correlation measures the strength and direction of the linear relationship between two variables. In the case of GPAs, it is typically a measure of the relationship between academic performance and another variable, such as study time or test scores.

In the undergraduate student group, the GPA range is wider, spanning from 1.0 to 4.0.

This means that there is a larger variability in the GPAs of undergraduate students, with some students performing poorly (close to 1.0) and others excelling (close to 4.0).

Consequently, correlations calculated within this group may be influenced by the presence of a diverse range of academic abilities.

It is possible that the correlations might be weaker or less consistent due to the broader range of performance levels.

On the other hand, graduate students are often required to have higher GPAs, typically ranging from 3.0 to 4.0.

This narrower range suggests that graduate students generally have higher academic performance, as they have already met certain criteria to be admitted to the graduate program.

In this case, correlations calculated within the graduate student group may reflect a more restricted range of performance, potentially leading to stronger and more consistent correlations.

Overall, the different GPA ranges between undergraduate and graduate students can influence correlations calculated within each group.

The wider range in undergraduate students may result in weaker correlations, whereas the narrower range in graduate students may yield stronger correlations due to the higher academic requirements.

By solving the separable differential equation dy/dt = 5(y - 10), we can separate the variables and integrate both sides, the particular solution satisfying the initial condition y(0) = 7 is: y(t) = e^(5t + ln(-3)) + 10.

First, let's separate the variables: dy/(y - 10) = 5 dt

Next, we integrate both sides: ∫ dy/(y - 10) = ∫ 5 dt

Integrating the left side gives us: ln|y - 10| = 5t + C

where C is the constant of integration.

Now, let's solve for y by taking the exponential of both sides:

|y - 10| = e^(5t + C)

Since e^(5t + C) is always positive, we can remove the absolute value sign: y - 10 = e^(5t + C)

To find the particular solution satisfying the initial condition y(0) = 7, we substitute t = 0 and y = 7 into the equation:

7 - 10 = e^(5(0) + C)

-3 = e^C

Solving for C: C = ln(-3)

Substituting C back into the equation, we have: y - 10 = e^(5t + ln(-3))

Finally, we can simplify the expression to obtain the particular solution:

y = e^(5t + ln(-3)) + 10

Therefore, the particular solution satisfying the initial condition y(0) = 7 is:

y(t) = e^(5t + ln(-3)) + 10.

The flux of the vector field F across the surface S, which is the tetrahedron enclosed by the coordinate planes and the plane y = 1 + 2x + 4z, can be calculated using the Divergence Theorem.

To calculate the flux of F across the surface S, we can use the Divergence Theorem, which states that the flux of a vector field F across a closed surface S is equal to the triple integral of the divergence of F over the volume V enclosed by S. The divergence of F is given by div(F) = ∂(zi)/∂x + ∂(yj)/∂y + ∂(zack)/∂z = 0 + 0 + a = a.

The given surface S is the tetrahedron enclosed by the coordinate planes (x = 0, y = 0, z = 0) and the plane y = 1 + 2x + 4z. To apply the Divergence Theorem, we need to find the volume V enclosed by S. Since S is a tetrahedron, its volume can be calculated using the formula V = (1/6) * base area * height.

The base of the tetrahedron is a triangle formed by the intersection of the coordinate planes and the given plane y = 1 + 2x + 4z. To find the area of this triangle, we can choose two of the coordinate planes and solve for their intersection with the given plane. Let's choose the xz-plane (y = 0) and the xy-plane (z = 0).

When y = 0, the equation of the plane becomes 0 = 1 + 2x + 4z, which simplifies to x = -1/2 - 2z. This gives us the two points (-1/2, 0, 0) and (0, 0, -1/4) on the triangle.

When z = 0, the equation of the plane becomes y = 1 + 2x, which gives us the point (0, 1, 0) on the triangle.

Using these three points, we can calculate the base area of the tetrahedron using the shoelace formula or any other suitable method.

Once we have the volume V and the divergence of F, we can apply the Divergence Theorem to calculate the flux of F across the surface S.

The probability of catching a defect is approximately 99.9768%.

To calculate the probability of catching a defect, we need to consider the complement of the event, which is the probability of not catching a defect in any of the four inspections.

The probability of not catching a defect in inspection 1 is 1 - 0.9 = 0.1 (since the complement of catching a defect is not catching a defect). Similarly, the probabilities of not catching a defect in inspections 2, 3, and 4 are 1 - 0.8 = 0.2, 1 - 0.12 = 0.88, and 1 - 0.95 = 0.05, respectively.

Since the inspections are independent events, we can multiply these probabilities together to find the probability of not catching a defect in all four inspections: 0.1 × 0.2 × 0.88 × 0.05 = 0.0088.

The indefinite integral of sec(x) is (1/2) ln|(1 + tan(x/2))/(1 - tan(x/2))| + C, where C is the constant of integration.

To find the indefinite integral of sec(x), we can use a technique called substitution.

Let u = tan(x/2), then we have: sec(x) = 1/cos(x) = 1/(1 - sin^2(x/2)) = 1/(1 - u^2). Also, dx = 2/(1 + u^2) du. Substituting these into the integral, we get: ∫sec(x) dx = ∫(1/(1 - u^2))(2/(1 + u^2)) du. Using partial fractions, we can write: 1/(1 - u^2) = (1/2)*[(1/(1 - u)) - (1/(1 + u))]

Substituting this into the integral, we get: ∫sec(x) dx = ∫[(1/2)((1/(1 - u)) - (1/(1 + u))))(2/(1 + u^2))] du. Simplifying this expression, we get: ∫sec(x) dx = (1/2)∫[(1/(1 - u))(2/(1 + u^2)) - (1/(1 + u))(2/(1 + u^2))] du

Using the natural logarithm identity ln|a/b| = ln|a| - ln|b|, we can simplify further: ∫sec(x) dx = (1/2) ln|(1 + u)/(1 - u)| + C. Substituting back u = tan(x/2), we get: ∫sec(x) dx = (1/2) ln|(1 + tan(x/2))/(1 - tan(x/2))| + C. Therefore, the indefinite integral of sec(x) is (1/2) ln|(1 + tan(x/2))/(1 - tan(x/2))| + C.

A conservative vector field is a vector field that can be represented as the gradient of a scalar function (potential function).

If a vector field is conservative, then the line integral of the vector field F along a path C that starts at point A and ends at point B depends only on the values of the potential function at A and B.

a. The maximum height of the ball is 0 feet (it reaches the highest point at ground level).

b. The velocity of the ball is one-half the initial velocity after 1.5 seconds.

c. When the velocity of the ball is one-half the initial velocity, the height of the ball is -180 feet (below ground level).

The pace at which an object's position changes in relation to a frame of reference and time is what is meant by velocity. Although it may appear sophisticated, velocity is just the act of moving quickly in one direction.

(a) To find the time it takes for the ball to reach its maximum height, we need to determine when its velocity becomes zero. We can use the kinematic equation for velocity:

v(t) = v₀ + at,

where v(t) is the velocity at time t, v₀ is the initial velocity, a is the acceleration, and t is the time.

In this case, the initial velocity is 96 ft/s, and the acceleration is -32 ft/s². Since the ball is thrown vertically upward, we consider the acceleration as negative.

Setting v(t) to zero and solving for t:

0 = 96 - 32t,

32t = 96,

t = 3 seconds.

Therefore, it takes 3 seconds for the ball to reach its maximum height.

To find the maximum height, we can use the kinematic equation for displacement:

s(t) = s₀ + v₀t + (1/2)at²,

where s(t) is the displacement at time t and s₀ is the initial displacement.

Since the ball is thrown from ground level, s₀ = 0. Plugging in the values:

s(t) = 0 + 96(3) + (1/2)(-32)(3)²,

s(t) = 144 - 144,

s(t) = 0.

Therefore, the maximum height of the ball is 0 feet (it reaches the highest point at ground level).

(b) We need to find the time at which the velocity of the ball is one-half the initial velocity.

Using the same kinematic equation for velocity:

v(t) = v₀ + at,

where v(t) is the velocity at time t, v₀ is the initial velocity, a is the acceleration, and t is the time.

In this case, we want to find the time when v(t) = (1/2)v₀:

(1/2)v₀ = v₀ - 32t.

Solving for t:

-32t = -(1/2)v₀,

t = (1/2)(96/32),

t = 1.5 seconds.

Therefore, the velocity of the ball is one-half the initial velocity after 1.5 seconds.

(c) We need to find the height of the ball when its velocity is one-half the initial velocity.

Using the same kinematic equation for displacement:

s(t) = [tex]s_0[/tex] + [tex]v_0[/tex]t + (1/2)at²,

where s(t) is the displacement at time t, [tex]s_0[/tex] is the initial displacement, [tex]v_0[/tex] is the initial velocity, a is the acceleration, and t is the time.

In this case, we want to find s(t) when t = 1.5 seconds and v(t) = (1/2)[tex]v_0[/tex]:

s(t) = 0 + [tex]v_0[/tex](1.5) + (1/2)(-32)(1.5)².

Substituting [tex]v_0[/tex] = 96 ft/s and solving for s(t):

s(t) = 96(1.5) - 144(1.5²),

s(t) = 144 - 324,

s(t) = -180 ft.

Therefore, when the velocity of the ball is one-half the initial velocity, the height of the ball is -180 feet (below ground level).

the equation of the tangent line to the graph of y = x^2 - 3 at the point (-2, 1) is y = -4x - 7.

To determine the equation of the tangent line to the graph of y = x^2 - 3 at the point (-2, 1), we need to find the slope of the tangent at that point and use it to write the equation in point-slope form.

First, let's find the derivative of the function y = x^2 - 3. Taking the derivative will give us the slope of the tangent line at any point on the curve.

dy/dx = 2x

Now, substitute the x-coordinate of the given point (-2, 1) into the derivative to find the slope at that point:

m = dy/dx = 2(-2) = -4

So, the slope of the tangent line at (-2, 1) is -4.

Next, we can use the point-slope form of a linear equation to write the equation of the tangent line:

y - y₁ = m(x - x₁)

where (x₁, y₁) is the given point and m is the slope.

Using (-2, 1) as the point and -4 as the slope, we have:

y - 1 = -4(x - (-2))

y - 1 = -4(x + 2)

y - 1 = -4x - 8

y = -4x - 7

The integral of 7cos(x)ln(sin(x)) dx evaluated from 0 is -7πln(2).

To evaluate the integral ∫ 7cos(x)ln(sin(x)) dx from 0, we first apply the integration by parts method. By selecting u = ln(sin(x)) and dv = 7cos(x) dx, we differentiate u and integrate dv to obtain du = (1/sin(x))cos(x) dx and v = 7sin(x), respectively.

Using the integration by parts formula ∫ u dv = uv - ∫ v du, we can calculate the integral:

∫ 7cos(x)ln(sin(x)) dx = 7sin(x)ln(sin(x)) - ∫ 7sin(x)(1/sin(x))cos(x) dx

= 7sin(x)ln(sin(x)) - 7∫ cos(x) dx

= 7sin(x)ln(sin(x)) - 7sin(x) + C

Now we substitute the limits of integration:

∫[0] 7cos(x)ln(sin(x)) dx = [7sin(x)ln(sin(x)) - 7sin(x)]|[0]

= 7sin(0)ln(sin(0)) - 7sin(0) - (7sin(π)ln(sin(π)) - 7sin(π))

= 0 - 0 - (0 - 0)

Answer:

Step-by-step explanation:

Volume = l³

Volume = (2 1/4)³

Volume = (2 1/4) × (2 1/4) ×(2 1/4)

Volume = (5 1/16) × (2 1/4)

Volume = 11 25/64 or 11.390625

Answer:

11 25/64 cubic inches

Step-by-step explanation:

The formula for the volume of a cube is [tex]V = s^{3}[/tex] or V = s × s × s, where V is the volume and s is the length of one side of the cube.

Inserting [tex]2\frac{1}{4}[/tex] in as s:

To convert the fraction [tex]\frac{729}{64}[/tex] to a mixed number, you would divide the numerator (729) by the denominator (64) to get 11 with a remainder of 25. The mixed number would be [tex]11\frac{25}{64}[/tex].

We can say that approximately 23 out of the 34 practice trials would fall between 59 and 61 seconds.

To determine the number of practice trials out of 34 that would fall between 59 and 61 seconds, we can utilize the properties of a normal distribution with the given mean and standard deviation.

Given that Alejandro's finishing times are normally distributed with a mean of 60 seconds and a standard deviation of 1 second, we can represent this distribution as follows:

μ = 60 (mean)

σ = 1 (standard deviation)

To find the proportion of trials that fall between 59 and 61 seconds, we need to calculate the area under the normal curve within this range. Since the normal distribution is symmetrical, we can determine this area by calculating the area under the curve between the mean and the upper and lower limits.

Using a standard normal distribution table or a statistical calculator, we can find the z-scores for the values 59 and 61, based on the mean and standard deviation. The z-score represents the number of standard deviations a data point is away from the mean.

For 59 seconds:

z = (59 - 60) / 1 = -1

For 61 seconds:

z = (61 - 60) / 1 = 1

Next, we find the area under the curve between these z-scores. By referring to a standard normal distribution table or using a calculator, we can determine the area associated with each z-score.

The area to the left of z = -1 is approximately 0.1587.

The area to the left of z = 1 is approximately 0.8413.

To find the area between these two z-scores, we subtract the smaller area from the larger area:

Area between z = -1 and z = 1 = 0.8413 - 0.1587 = 0.6826

This means that approximately 68.26% of the trials will fall between 59 and 61 seconds.

To find the number of trials out of 34 that fall within this range, we multiply the proportion by the total number of trials:

Number of trials between 59 and 61 seconds = 0.6826 * 34 ≈ 23.23

Rounding this to the nearest whole number, we can say that approximately 23 out of the 34 practice trials would fall between 59 and 61 seconds.

To determine whether the set B = {1, 1 + 6x + 8x^2} is a basis for the vector space V = P2 (the space of polynomials of degree at most 2), we need to check if B is linearly independent and if it spans V.

First, we check for linear independence. If the only way to obtain the zero polynomial from the polynomials in B is by setting all coefficients equal to zero, then B is linearly independent.

In this case, since we only have two polynomials in B, we can check if they are linearly dependent by equating a linear combination of the polynomials to zero and solving for the coefficients. If the only solution is the trivial solution (all coefficients are zero), then B is linearly independent.

Next, we check if B spans V. If every polynomial in V can be expressed as a linear combination of the polynomials in B, then B spans V.

By performing these checks, we can determine whether the set B is a basis for the vector space V.

The total volume of the part consisting of the cone on top of the cylinder is approximately 522.89 cubic centimeters (cm³).

We have,

To calculate the total volume of the part consisting of a cone on top of a cylinder, we need to find the volume of the cone and the cylinder separately, and then add them together.

First, let's calculate the volume of the cone using the given dimensions:

The radius of the cone (r) = 4 cm

The slant height of the cone (l) = 11 cm

The height of the cone (h) can be found using the Pythagorean theorem:

h = √(l² - r²)

h = √(11² - 4²)

h = √(121 - 16)

h = √105

h ≈ 10.25 cm

Now we can calculate the volume of the cone using the formula:

V_cone = (1/3) x π x r² x h

V_cone = (1/3) x π x 4² x 10.25

V_cone ≈ 171.03 cm³

Next, let's calculate the volume of the cylinder using the given dimensions:

Radius of the cylinder (r) = 4 cm

Height of the cylinder (h) = 7 cm

The volume of the cylinder is given by the formula:

V_cylinder = π x r² x h

V_cylinder = π x 4² x 7

V_cylinder ≈ 351.86 cm³

Finally, to find the total volume of the part, we add the volumes of the cone and the cylinder:

Total Volume = V_cone + V_cylinder

Total Volume ≈ 171.03 cm³ + 351.86 cm³

Total Volume ≈ 522.89 cm³

Therefore,

The total volume of the part consisting of the cone on top of the cylinder is approximately 522.89 cubic centimeters (cm³).

The limit of (x^2 - 1)/(√(3x + 1) - 1) as x approaches 2 does not exist.

To evaluate the limit, we can substitute the value of x into the given expression and see if it converges to a finite value. Plugging in x = 2, we get:

[(2^2) - 1] / [√(3(2) + 1) - 1]

= (4 - 1) / (√(6 + 1) - 1)

= 3 / (√7 - 1)

Since the denominator contains a radical term, we need to rationalize it. Multiplying both the numerator and denominator by the conjugate of the denominator (√7 + 1), we have:

3 / (√7 - 1) * (√7 + 1) / (√7 + 1)

= (3 * (√7 + 1)) / ((√7 - 1) * (√7 + 1))

= (3√7 + 3) / (7 - 1)

= (3√7 + 3) / 6

Therefore, the value of the expression at x = 2 is (3√7 + 3) / 6. However, this value does not represent the limit of the expression as x approaches 2, as it only gives the value at that specific point.

To determine the limit, we need to investigate the behavior of the expression as x approaches 2 from both sides.

By analyzing the behavior of the numerator and denominator separately, we find that as x approaches 2, the numerator approaches a finite value, but the denominator approaches zero. Since we have an indeterminate form of 0/0, the limit does not exist.

To find (F^(-1))(a) for the function f(x) = cos(3x) and a = 1, we need to find the value of x such that f(x) = a.

Since a = 1, we have to solve the equation f(x) = cos(3x) = 1.

To find the inverse function, we switch the roles of x and f(x) and solve for x.

In Chapter 1 we discussed the limit of sequences that were monotone; this restriction allowed some short-cuts and gave a quick introduction to the concept.

But many important sequences are not monotone—numerical methods, for instance, often lead to sequences which approach the desired answer alternately

from above and below. For such sequences, the methods we used in Chapter 1

won’t work. For instance, the sequence

1.1, .9, 1.01, .99, 1.001, .999, ...

has 1 as its limit, yet neither the integer part nor any of the decimal places of the

numbers in the sequence eventually becomes constant. We need a more generally

applicable definition of the limit.

We abandon therefore the decimal expansions, and replace them by the approximation viewpoint, in which “the limit of {an} is L” means roughly

an is a good approximation to L , when n is large.

The following definition makes this precise. After the definition, most of the

rest of the chapter will consist of examples in which the limit of a sequence is

calculated directly from this definition. There are “limit theorems” which help in

determining a limit; we will present some in Chapter 5. Even if you know them,

don’t use them yet, since the purpose here is to get familiar with the definition

When a number is divided by [tex]10^1[/tex] (10), each digit in the number has a value that is 1/10 of its value in the original number. Thus, the correct answer is option C: Each digit has a value that is 1/10 of its value in the original number.

When a number is divided by [tex]10^1[/tex] (which is 10), the value of each digit in the number is reduced by a factor of 10.

To understand this, let's consider a number with digits in the place value system. Each digit represents a specific value based on its position in the number. For example, in the number 1234, the digit '1' represents 1000, the digit '2' represents 200, the digit '3' represents 30, and the digit '4' represents 4.

When we divide this number by 10^1 (which is 10), we are essentially shifting all the digits one place to the right. In other words, we are moving the decimal point one place to the left. The result would be 123.4.

Now, let's observe the changes in the digit values:

The digit '1' in the original number had a value of 1000, and in the result, it has a value of 10. So, its value has decreased by a factor of 10 (1/10).

The digit '2' in the original number had a value of 200, and in the result, it has a value of 2. So, its value has also decreased by a factor of 10 (1/10).

The digit '3' in the original number had a value of 30, and in the result, it has a value of 0.3. So, its value has also decreased by a factor of 10 (1/10).

The digit '4' in the original number had a value of 4, and in the result, it has a value of 0.04. So, its value has also decreased by a factor of 10 (1/10).

Therefore, when a number is divided by [tex]10^1[/tex] (10), each digit in the number has a value that is 1/10 of its value in the original number. Thus, the correct answer is option C: Each digit has a value that is 1/10 of its value in the original number.
