4) Two common techniques used to algebraically solve limits are factoring and using conjugates. Factoring involves manipulating the algebraic expression to simplify it and cancel out common factors, which can help in evaluating the limit. Using conjugates is another technique where the numerator or denominator is multiplied by its conjugate to eliminate radicals or complex numbers, facilitating the computation of the limit.

To compute the limit lim(x→1) (2x^3 - x^2 - x + 1) using factoring, we can factor the expression as (x - 1)(2x^2 + x - 1). Since the limit is evaluated as x approaches 1, we can substitute x = 1 into the factored form to find the limit. Thus, the result is (1 - 1)(2(1)^2 + 1 - 1) = 0.

To compute the limit lim(x→4) (x^4 - x^-4) using conjugates, we can multiply the numerator and denominator by the conjugate of x^4 - x^-4, which is x^4 + x^-4. This simplifies the expression as (x^8 - 1)/(x^4). Substituting x = 4 into the simplified expression gives us (4^8 - 1)/(4^4) = (65536 - 1)/256 = 25385/256.

The vector r(t) can be written in the form a = a + T + aN at the given value of t without explicitly finding T and N as: [tex]r(t) = (-4i - 9j - 9k) + ((-2)i + (-3)j + (-2t)k) + (-2i - 3j - 6k)[/tex].

To express the vector [tex]r(t) = (-2t + 2)i + (-3t)j + (-t^2)k[/tex] in the form a = a + T + aN at t = 3, we need to find the values of a, T, and aN.

First, we find a by substituting t = 3 into the given vector r(t):

[tex]a = (-2(3) + 2)i + (-3(3))j + (-(3)^2)k\\ = (-6 + 2)i + (-9)j + (-9)k \\ = -4i - 9j - 9k[/tex]

Next, we find T by differentiating r(t) with respect to t:

[tex]T = dr/dt = (-2)i + (-3)j + (-2t)k[/tex]

Finally, we find aN by substituting t = 3 into T:

[tex]aN = (-2)i + (-3)j + (-2(3))k \\ = (-2)i + (-3)j + (-6)k \\ = -2i - 3j - 6k[/tex]

Therefore, the expression of [tex]r(t) = (-2t + 2)i + (-3t)j + (-t^2)k[/tex] in the form a = a + T + aN at t = 3 is:

[tex]r(t) = (-4i - 9j - 9k) + ((-2)i + (-3)j + (-2t)k) + (-2i - 3j - 6k)[/tex]

The total amount of liquid that leaked out is 102.75 liters, and the upper estimate is 108.75 liters.

To find the lower and upper estimates for the total amount of liquid that leaked out, we can use the trapezoidal rule to approximate the integral of the leakage rate over the given time intervals.

t (hr)   r(t) (L/h)

0           10.6

5           9.5

10         8.6

15         7.7

20         6.9

25         6.2

Calculate the time intervals and average the rates

To calculate the lower and upper estimates, we divide the given time period into subintervals. Since the intervals are 5 hours, we have 5 subintervals: [0, 5], [5, 10], [10, 15], [15, 20], [20, 25].

For each subinterval, we calculate the average rate using the given values:

Average rate for [0, 5] = (10.6 + 9.5) / 2 = 10.05 L/h

Average rate for [5, 10] = (9.5 + 8.6) / 2 = 9.05 L/h

Average rate for [10, 15] = (8.6 + 7.7) / 2 = 8.15 L/h

Average rate for [15, 20] = (7.7 + 6.9) / 2 = 7.3 L/h

Average rate for [20, 25] = (6.9 + 6.2) / 2 = 6.55 L/h

Calculate the lower and upper estimates using the trapezoidal rule

The lower estimate is obtained by approximating the integral as a sum of areas of trapezoids, where the height of each trapezoid is the average rate and the width is the time interval.

Lower estimate = (5/2) * [(10.05) + (9.05) + (8.15) + (7.3) + (6.55)]

               = (5/2) * [41.1]

               = 102.75 L

The upper estimate is obtained by using the average rate of the previous interval as the height of the first trapezoid and the average rate of the current interval as the height of the second trapezoid.

Upper estimate = (5/2) * [(10.6) + (9.5) + (8.6) + (7.7) + (6.9)]

               = (5/2) * [43.5]

               = 108.75 L

Therefore, the lower estimate for the total amount of liquid that leaked out is 102.75 liters, and the upper estimate is 108.75 liters.

Times are the acceleration zero, t = 2.5 is the only time when the acceleration is zero.

The acceleration of the particle can be found by taking the second derivative of the equation of motion, s(t) = 2t³ - 15t² + 36t + 2. To find the times when the acceleration is zero, we need to solve the equation a(t) = s''(t) = 0.

Taking the second derivative of s(t), we have s''(t) = 12t - 30. Setting this equal to zero, we get: 12t - 30 = 0

Solving for t, we find t = 2.5. Therefore, the acceleration is zero at t = 2.5 seconds.

To confirm that this is the only time when the acceleration is zero, we can examine the behavior of the acceleration function. Since the coefficient of t in the acceleration function is positive (12 > 0), the acceleration is increasing for t > 2.5 and decreasing for t < 2.5. This implies that the acceleration is negative for t < 2.5 and positive for t > 2.5. Thus, t = 2.5 is the only time when the acceleration is zero.

The height of the tree can be determined using the concept of similar triangles. With an 18-foot shadow and a 40-foot height for the building. The height of the tree is approximately 45 feet.

Let's consider the similar triangles formed by the tree, its shadow, the building, and its shadow. The ratio of the height of the tree to the length of its shadow is the same as the ratio of the height of the building to the length of its shadow. We can set up a proportion to solve for the height of the tree.

Using the given information, we have:

Tree's shadow: 18 feet

Building's shadow: 16 feet

Building's height: 40 feet

Let x be the height of the tree. We can set up the proportion as follows:

x / 18 = 40 / 16

Cross-multiplying, we get:

16x = 18 * 40

Simplifying, we have:

16x = 720

Dividing both sides by 16, we find:

the total distance traveled by the particle over the time period is 14/3 meters.

To find the displacement of the particle over the time period, we need to integrate the velocity function v(t) over the given interval.

A) Displacement:

The displacement is given by the definite integral of the velocity function v(t) over the interval [1, 6]:

Displacement = ∫[1, 6] (t^2 - 2t - 8) dt

To evaluate this integral, we can use the power rule of integration:

Displacement = [(1/3) * t^3 - t^2 - 8t] evaluated from 1 to 6

= [(1/3) * (6^3) - 6^2 - 8 * 6] - [(1/3) * (1^3) - 1^2 - 8 * 1]

= [72 - 36 - 48] - [1/3 - 1 - 8]

= -12 - (-22/3)

= -12 + 22/3

= (-36 + 22)/3

= -14/3

Therefore, the displacement of the particle over the time period is -14/3 meters.

B) Total Distance:

To find the total distance traveled by the particle over the time period, we need to consider the absolute value of the velocity function and integrate it over the interval [1, 6]:

Total Distance = ∫[1, 6] |t^2 - 2t - 8| dt

Since the velocity function is already non-negative for the given interval, we can calculate the total distance by evaluating the integral of v(t) directly:

Total Distance = ∫[1, 6] (t^2 - 2t - 8) dt

Using the same integral from part A, we can evaluate it as:

Total Distance = (-14/3) meters

The equation for the line tangent to the curve at the point defined by t = 4 is:

y - y(4) = (dy/dx)(x - x(4))

To get the equation for the line tangent to the curve at the point defined by t = 4, we need to find the first derivative dy/dx and evaluate it at t = 4. Then, we can use this derivative to find the slope of the tangent line. Additionally, we can get the value of dx at t = 4 to determine the change in x.

Let's start by obtaining the derivatives:

x = 4sin(t)

y = 4cos(t)

To get dy/dx, we differentiate both x and y with respect to t and apply the chain rule:

dx/dt = 4cos(t)

dy/dt = -4sin(t)

Now, we can calculate dy/dx by dividing dy/dt by dx/dt:

dy/dx = (dy/dt) / (dx/dt)

= (-4sin(t)) / (4cos(t))

= -tan(t)

To get the value of dy/dx at t = 4, we substitute t = 4 into the expression for dy/dx:

dy/dx = -tan(4)

Next, we get the value of dx at t = 4 by substituting t = 4 into the expression for x:

dx = 4sin(4)

Therefore, the equation for the line tangent to the curve at the point defined by t = 4 is:

y - y(4) = (dy/dx)(x - x(4))

where y(4) and x(4) are the coordinates of the point on the curve at t = 4, and (dy/dx) is the derivative evaluated at t = 4.

To get the value of dx, we substitute t = 4 into the expression for x:

dx = 4sin(4)

Please note that the exact numerical values for the slope and dx would depend on the specific value of tan(4) and sin(4), which would require evaluating them using a calculator or other mathematical tools.

Closure under addition: Let (x1, y1, z1) and (x2, y2, z2) be two vectors in S. We need to show that their sum (x1 + x2, y1 + y2, z1 + z2) is also in S. However, if we add the equations x1 + y1 + 2z1 - 1 = 0 and x2 + y2 + 2z2 - 1 = 0, we get (x1 + x2) + (y1 + y2) + 2(z1 + z2) - 2 = 0.

Since the constant term is -2 instead of -1, the sum is not in S, violating closure under addition. Closure under scalar multiplication: If (x, y, z) is in S, then for any scalar c, we need to show that c(x, y, z) is also in S. However, if we multiply the equation x + y + 2z - 1 = 0 by c, we get cx + cy + 2cz - c = 0.

The curve defined by the equation y = 3e^x/(e^x - 6) has a horizontal asymptote at y = 3 and no vertical asymptotes.

To find the horizontal asymptote, we examine the behavior of the function as x approaches positive or negative infinity. When x becomes very large (approaching positive infinity), the term e^x in both the numerator and denominator dominates the equation. The exponential function grows much faster than the constant term -6, so we can disregard the -6 in the denominator. Therefore, the function approaches y = 3e^x/e^x, which simplifies to y = 3 as x goes to infinity. Similarly, as x approaches negative infinity, the function still approaches y = 3.

Regarding vertical asymptotes, we check for values of x where the denominator e^x - 6 becomes zero. However, no real value of x satisfies this condition, as the exponential function e^x is always positive and never equals 6. Hence, there are no vertical asymptotes for this curve.

In summary, the curve defined by y = 3e^x/(e^x - 6) has a horizontal asymptote at y = 3, which the function approaches as x goes to positive or negative infinity. There are no vertical asymptotes for this curve.

RM261.84 is the payment to be made at the end of every quarter. RM1,857.92 is the interest charged on the annuity.

To calculate the payment to be made at the end of every quarter, we can use the formula for the present value of an annuity:

PV = PMT * (1 - (1 + r)^(-n)) / r

Where:

PV = Present value of the annuity

PMT = Payment to be made at the end of every quarter

r = Interest rate per period

n = Number of periods

In this case, the present value (PV) is RM5,000, the interest rate (r) is 6% compounded quarterly, and the number of periods (n) is 3 years, which is equivalent to 12 quarters.

(a) Calculate the payment to be made at the end of every quarter:

PV = PMT * (1 - (1 + r)^(-n)) / r

5000 = PMT * (1 - (1 + 0.06/4)^(-12)) / (0.06/4)

Let's solve this equation for PMT:

5000 = PMT * (1 - (1.015)^(-12)) / (0.015)

5000 * (0.015) = PMT * (1 - (1.015)^(-12))

75 = PMT * (1 - 0.7136)

PMT * 0.2864 = 75

PMT = 75 / 0.2864

PMT ≈ RM261.84

So, the payment to be made at the end of every quarter is approximately RM261.84.

(b) Calculate the interest charged on the annuity:

To calculate the interest charged on the annuity, we can subtract the total amount of payments made from the initial investment:

Total Payments = PMT * n

Total Payments = RM261.84 * 12

Total Payments ≈ RM3,142.08

Interest Charged = PV - Total Payments

Interest Charged = RM5,000 - RM3,142.08

Interest Charged ≈ RM1,857.92

Therefore, the interest charged on the annuity is approximately RM1,857.92.

The given function is f(x) = 1/(x + 5)^2.

involved in evaluating this function:

1. Take a number x.

2. Add 5 to the number x: (x + 5).

3. Square the result from step 2: (x + 5)^2.

4. Take the reciprocal of the result from step 3: 1/(x + 5)^2.

So, the function f(x) takes a number x, adds 5, squares the result, and finally takes the reciprocal of that squared result.

To better understand the behavior of the function, let's consider some examples by plugging in values for x:

Example 1: For x = 0,

f(0) = 1/(0 + 5)^2 = 1/25 = 0.04

Example 2: For x = 3,

f(3) = 1/(3 + 5)^2 = 1/64 ≈ 0.015625

Example 3: For x = -2,

f(-2) = 1/(-2 + 5)^2 = 1/9 ≈ 0.111111

we can observe that as x increases, the function f(x) approaches zero. Additionally, as x approaches -5 (the value being added), the function tends towards infinity. This behavior is due to the squaring and reciprocal operations in the function.

It's important to note that the function is defined for all real numbers except -5, as the denominator (x + 5) cannot be equal to zero.

To find the area of the parallelogram determined by the vectors v = (4, 2, -5) and w = (-1, 0, 3), we can use the cross product.

The cross product of two vectors gives a vector perpendicular to both vectors and whose magnitude represents the area of the parallelogram they span.

Let's calculate the cross product of v and w:

v x w = (4, 2, -5) x (-1, 0, 3)

= [(2 * 3) - (0 * (-5)), (-5 * (-1)) - (3 * 4), (4 * 0) - (2 * (-1))]

= (6 - 0, 5 - 12, 0 - (-2))

= (6, -7, 2)

The magnitude of v x w represents the area of the parallelogram:

Area = |v x w| = sqrt(6^2 + (-7)^2 + 2^2) = sqrt(36 + 49 + 4) = sqrt(89)

Therefore, the area of the parallelogram determined by the vectors v = (4, 2, -5) and w = (-1, 0, 3) is sqrt(89).

To find the angle between the planes 5x - 2y - 3z = 4 and 3x + y - 4z = 1, we can find the normal vectors of the planes and then calculate the angle between them using the dot product.

The normal vector of a plane is the vector that is perpendicular to the plane and has components corresponding to the coefficients of x, y, and z in the plane equation.

Let's find the normal vectors of the planes:

For the first plane 5x - 2y - 3z = 4, the normal vector is (5, -2, -3).

For the second plane 3x + y - 4z = 1, the normal vector is (3, 1, -4).

The angle between two vectors can be calculated using the dot product formula:

cos(theta) = (v · w) / (|v| * |w|)

Let's calculate the angle between the normal vectors:

cos(theta) = [(5, -2, -3) · (3, 1, -4)] / (|(5, -2, -3)| * |(3, 1, -4)|)

= (5 * 3) + (-2 * 1) + (-3 * -4) / sqrt(5^2 + (-2)^2 + (-3)^2) * sqrt(3^2 + 1^2 + (-4)^2)

= 15 - 2 + 12 / sqrt(25 + 4 + 9) * sqrt(9 + 1 + 16)

= 25 / sqrt(38) * sqrt(26)

= 25 / sqrt(38 * 26)

≈ 0.926

Now, we can find the angle by taking the inverse cosine (arccos) of the value:

theta = arccos(0.926)

≈ 22.33 degrees (to the nearest degree)

Therefore, the angle between the planes 5x - 2y - 3z = 4 and 3x + y - 4z = 1 to the nearest degree is approximately 22 degrees.

The inverse Fourier transform of F₂(jw) is given by f₂(t) = δ(t - 1/4) + δ(t + 1/4).

(a) To find the inverse Fourier transform of F₁(jw) = 1/(3+w) + 1/(4-jw), we can use the linearity property of the Fourier transform.

The inverse Fourier transform of F₁(jw) can be calculated by taking the inverse Fourier transforms of each term separately.

Let's denote the inverse Fourier transform of F₁(jw) as f₁(t).

Inverse Fourier transform of 1/(3+w):

Using the table of Fourier transforms,

F⁻¹{1/(3+w)} = e^(-3t) u(t)

Inverse Fourier transform of 1/(4-jw):

Using the table of Fourier transforms, we have:

F⁻¹{1/(4-jw)} = e^(4t) u(-t)

Now, applying the linearity property of the inverse Fourier transform, we get:

f₁(t) = F⁻¹{F₁(jw)}

      = F⁻¹{1/(3+w)} + F⁻¹{1/(4-jw)}

      = e^(-3t) u(t) + e^(4t) u(-t)

Therefore, the inverse Fourier transform of F₁(jw) is given by f₁(t) = e^(-3t) u(t) + e^(4t) u(-t).

(b) To find the inverse Fourier transform of F₂(jw) = cos(4w + π/3), we can use the table of Fourier transforms and properties of the Fourier transform.

Using the table of Fourier transforms, we know that the inverse Fourier transform of cos(aw) is given by δ(t - 1/a) + δ(t + 1/a).

In this case, a = 4, so we have:

F⁻¹{cos(4w + π/3)} = δ(t - 1/4) + δ(t + 1/4)

Therefore, the inverse Fourier transform of F₂(jw) is given by f₂(t) = δ(t - 1/4) + δ(t + 1/4).

In a bag, there are 4 red marbles and 3 yellow marbles. Marbles are drawn at random from the bag, without replacement, until a red marble is obtained. We want to find the probability distribution, mean, and variance of the variable X, which represents the total number of marbles drawn.

i. To find the probability distribution of variable X, we need to calculate the probability of drawing each possible number of marbles before getting a red marble. Since we are drawing without replacement, the probability changes with each draw. The probability distribution is as follows:

X = 1: P(X=1) = 4/7 (the first draw is red)

X = 2: P(X=2) = (3/7) * (4/6) (the first draw is yellow, and the second draw is red)

X = 3: P(X=3) = (3/7) * (2/6) * (4/5) (the first two draws are yellow, and the third draw is red)

X = 4: P(X=4) = (3/7) * (2/6) * (1/5) * (4/4) (all four draws are yellow, and the fourth draw is red)

ii. To find the mean of variable X, we multiply each possible value of X by its corresponding probability and sum them up. The mean of X is given by:

Mean(X) = 1 * P(X=1) + 2 * P(X=2) + 3 * P(X=3) + 4 * P(X=4)

iii. To find the variance of variable X, we calculate the squared difference between each value of X and the mean, multiply it by the corresponding probability, and sum them up. The variance of X is given by:

Variance(X) = [(1 - Mean(X))^2 * P(X=1)] + [(2 - Mean(X))^2 * P(X=2)] + [(3 - Mean(X))^2 * P(X=3)] + [(4 - Mean(X))^2 * P(X=4)]

By calculating the above expressions, we can determine the probability distribution, mean, and variance of the variable X, which represents the total number of marbles drawn before obtaining a red marble.

The given sequence does converge.

The given sequence converges, meaning it approaches a specific value as the terms progress. The first five terms of the sequence can be determined by substituting different values for 'n' into the expression. By substituting 'n' with 1, 2, 3, 4, and 5, we can calculate the corresponding terms of the sequence.

The sequence is as follows: -6, 25/4, -4/27, 8/125, and -3273125. To determine whether the sequence converges, we need to observe the behavior of the terms as 'n' increases. In this case, as 'n' increases, the terms oscillate between negative and positive values, indicating that the sequence does not approach a single limiting value.

Hence, the sequence does not converge.

Answer:

Step-by-step explanation:

This is an answer.

The integrals of A is 4 * (x * ln(x) - x) + C and The integrals of B is (1/7) * x⁷ - (1/2) * x⁴ + C.

1. Finding the derivatives:

a. f(x) = x³ + 2x² + 1

  f'(x) = 3x² + 4x

b. f(x) = log(4x + 3)

  f'(x) = 4 / (4x + 3)

c. f(x) = sin(x² + 2)

  f'(x) = cos(x² + 2) * 2x

d. f(x) = 5 * ln(x-3)²

  To find the derivative of this function, we can apply the chain rule:

  Let u = ln(x-3)², then f(x) = 5 * u

  Applying the chain rule:

  f'(x) = 5 * (du/dx)

         = 5 * (2 * ln(x-3) * (1/(x-3)))

         = 10 * ln(x-3) / (x-3)

2. Evaluating the integrals:

a. ∫4 ln(x) dx

  This integral can be evaluated using integration by parts:

  Let u = ln(x) and dv = dx

  Then, du = (1/x) dx and v = x

  Applying the integration by parts formula:

  ∫ u dv = uv - ∫ v du

  ∫4 ln(x) dx = 4 * (x * ln(x) - ∫ x * (1/x) dx)

             = 4 * (x * ln(x) - ∫ dx)

             = 4 * (x * ln(x) - x) + C

b. ∫(x⁶ - 2x³) dx

  To integrate this polynomial, we can use the power rule for integration:

  ∫ xⁿ dx = (x^(n+1))/(n+1) + C

  Applying the power rule:

  ∫(x⁶ - 2x³) dx = (x⁷)/7 - (2x⁴)/4 + C

                   = (1/7) * x⁷ - (1/2) * x⁴ + C

Please note that C represents the constant of integration.

To find the abscissa of the midpoint of two points, we can use the midpoint formula. The midpoint formula states that the x-c coordinate of the midpoint is the average of the x-coordinates of the two points.

For the points A(-10, 19) and B(8, -10), the x-coordinate of the midpoint is calculated as follows: x-coordinate of midpoint = (x-coordinate of A + x-coordinate of B) / 2.  Substituting the values, we have: x-coordinate of midpoint = (-10 + 8) / 2

x-coordinate of midpoint = -2 / 2

x-coordinate of midpoint = -1

Therefore, the abscissa for the midpoint of A(-10, 19) and B(8, -10) is -1. This means that the midpoint lies on the vertical line with x-coordinate -1.

The absolute maximum value Ty is 2.

We have,

To find the absolute maximum and minimum values of the function

f(x, y) = 4x + 4y subject to the constraint g(x, y) = 16x - 18y + 10 = 1, we can use the method of Lagrange multipliers.

First, we define the Lagrangian function L(x, y, λ) as:

L(x, y, λ) = f(x, y) - λ * (g(x, y) - 1)

where λ is the Lagrange multiplier.

Next, we need to find the critical points of L by taking the partial derivatives and setting them to zero:

∂L/∂x = 4 - λ * 16 = 0

∂L/∂y = 4 - λ * (-18) = 0

∂L/∂λ = 16x - 18y + 10 - 1 = 0

From the first equation, we have 4 - 16λ = 0, which gives λ = 1/4.

From the second equation, we have 4 + 18λ = 0, which gives λ = -2/9.

Since these two values of λ do not match, we have a contradiction.

This means that there are no critical points inside the region defined by the constraint.

Therefore, to find the absolute maximum and minimum values, we need to consider the boundary of the region.

The constraint g(x, y) = 16x - 18y + 10 = 1 represents a straight line.

To find the absolute maximum and minimum values on this line, we can substitute y = (16x + 9)/18 into the function f(x, y):

f(x) = 4x + 4((16x + 9)/18)

= 4x + (64x + 36)/18

= (98x + 36)/18

To find the absolute maximum and minimum values of f(x) on the line, we can differentiate f(x) with respect to x and set it to zero:

df/dx = 98/18 = 0

Solving this equation, we find x = 0.

Substituting x = 0 into the line equation g(x, y) = 16x - 18y + 10 = 1, we get y = (16*0 + 9)/18 = 9/18 = 1/2.

Therefore,

The absolute maximum value of f(x, y) subject to the constraint is f(0, 1/2) = (98*0 + 36)/18 = 2, and the absolute minimum value is also f(0, 1/2) = 2.

Thus,

The absolute maximum value Ty is 2.
