(2 points) 11. Consider an object moving along the curve r(t) = i + (5 cost)j + (3 sin t)k. At what times from 1 to 4 seconds are the velocity and acceleration vectors perpendicular?

Answers

Answer 1

The velocity and acceleration vectors are perpendicular at t = 1.57 seconds and t = 4.71 seconds.

To find the times from 1 to 4 seconds when the velocity and acceleration vectors are perpendicular, we need to determine when the dot product of the velocity and acceleration vectors is equal to zero.

Given the curve r(t) = i + (5 cos(t))j + (3 sin(t))k, we can find the velocity and acceleration vectors by differentiating with respect to time.

Velocity vector:

v(t) = dr(t)/dt = -5 sin(t)i + (-5 cos(t))j + 3 cos(t)k

Acceleration vector:

a(t) = dv(t)/dt = -5 cos(t)i + 5 sin(t)j - 3 sin(t)k

Now, we calculate the dot product of the velocity and acceleration vectors:

v(t) · a(t) = (-5 sin(t)i + (-5 cos(t))j + 3 cos(t)k) · (-5 cos(t)i + 5 sin(t)j - 3 sin(t)k)

= 25 sin(t) cos(t) + 25 sin(t) cos(t) + 9 sin(t) cos(t)

= 50 sin(t) cos(t) + 9 sin(t) cos(t)

= 59 sin(t) cos(t)

For the dot product to be zero, we have:

59 sin(t) cos(t) = 0

This equation is satisfied when sin(t) = 0 or cos(t) = 0.

When sin(t) = 0, we have t = 0, π, 2π, 3π, and so on.

When cos(t) = 0, we have t = π/2, 3π/2, 5π/2, and so on.

However, we are only interested in the times from 1 to 4 seconds. Therefore, the valid times when the velocity and acceleration vectors are perpendicular are:

t = π/2, 3π/2 (corresponding to 1.57 seconds and 4.71 seconds, respectively)

In summary, the velocity and acceleration vectors are perpendicular at t = 1.57 seconds and t = 4.71 seconds.

1. Consider the relation R on the set A = {0, 1, 2, 3, 4}, defined by: == aRb a=bc and b=ad, for some c, d E A. = (a) Is R an equivalence relation on A? If so, prove it. If not, show why not. (b) Is R

Answers

Since a = 1 cannot be written in the form bc for any c E A. Therefore, R is not transitive and hence, not an equivalence relation on A.

(a) Yes, R is an equivalence relation on A.The relation R is an equivalence relation if it satisfies the following properties:

Reflexive: Each element of A is related to itself.i.e. aRa for all a E A.Each element a of A can be written in the form a = bc and b = ad for some c, d E A, then aRa, since a = bc = adc = dbc, and thus aRa.Symmetric: If a is related to b, then b is related to a.i.e., if aRb, then bRa.

Transitive: If a is related to b and b is related to c, then a is related to c.i.e., if aRb and bRc, then aRc.Suppose aRb and bRc, then there exists c, d, e, and f such that:a = bd,b = ae, and c = bf.

Then, a = b(d) = a(e)(d) = c(e)(d), so aRc. Hence, R is an equivalence relation.(b) R is not an equivalence relation on A.

This is because the relation R is not transitive.

Suppose a = 1, b = 2, and c = 3.

Then, aRb since a = bc with c = 2. Similarly, bRc since b = ad with d = 3.

However, a is not related to c, since a = 1 cannot be written in the form bc for any c E A. Therefore, R is not transitive and hence, not an equivalence relation on A.

To solve the given integral expression, we will evaluate each integral separately and then subtract the results.

Integral 1 can be evaluated as follows:

[tex]\(\int (x^4 - x^2 + 2e^x) \, dx\)[/tex]

To find the antiderivative of each term, we apply the power rule and the rule for integrating [tex]\(e^x\)[/tex]:

[tex]\(\int x^4 \, dx = \frac{x^5}{5} + C_1\)\\\(\int -x^2 \, dx = -\frac{x^3}{3} + C_2\)\\\(\int 2e^x \, dx = 2e^x + C_3\)[/tex]

Therefore, the result of the first integral is:

[tex]\(\int (x^4 - x^2 + 2e^x) \, dx = \frac{x^5}{5} - \frac{x^3}{3} + 2e^x + C_1\)[/tex]

Integral 2 can be evaluated as follows:

[tex]\(\int (x^5 - 2x^2e^x) \, dx\)[/tex]

Using the power rule and the rule for integrating [tex]\(e^x\)[/tex], we have:

[tex]\(\int x^5 \, dx = \frac{x^6}{6} + C_4\)\\\(\int -2x^2e^x \, dx = -2e^x(x^2 - 2x + 2) + C_5\)[/tex]

Thus, the result of the second integral is:

[tex]\(\int (x^5 - 2x^2e^x) \, dx = \frac{x^6}{6} - 2e^x(x^2 - 2x + 2) + C_5\)[/tex]

Now, we can subtract the second integral from the first to get the final value:

[tex]\[\int (x^4 - x^2 + 2e^x) \, dx - \int (x^5 - 2x^2e^x) \, dx = \left(\frac{x^5}{5} - \frac{x^3}{3} + 2e^x + C_1\right) - \left(\frac{x^6}{6} - 2e^x(x^2 - 2x + 2) + C_5\right)\][/tex]

Simplifying this expression further will depend on the specific limits of integration, if any, or if the problem requires a definite integral.

Answers

The volume of the region R bounded by the curves[tex]24 + y^2 = 5[/tex]and[tex]y = 2x^2[/tex], with -1 ≤ x ≤ 1, is approximately 20.2 cubic units.

To evaluate the volume of the region R, we can set up a double integral in the xy-plane. The integral expresses the volume of the region R as the difference between the upper and lower boundaries in the y-direction.

The integral to evaluate the volume is given by:

∫∫R dV = ∫[from -1 to 1] ∫[from [tex]2x^2[/tex] to √(5-24+[tex]y^2[/tex])] dy dx

Simplifying the limits of integration, we have:

∫∫R dV = ∫[from -1 to 1] ∫[from [tex]2x^2[/tex] to √(5-24+ [tex]y^2[/tex])] dy dx

Now, we can evaluate the integral:

∫∫R dV = ∫[from -1 to 1] [√(5-24+[tex]y^2[/tex]) - [tex]2x^2[/tex]] dy dx

Evaluating the integral with respect to y, we get:

∫∫R dV = ∫[from -1 to 1] [√(5-24+ [tex]y^2[/tex]) - [tex]2x^2[/tex]] dy

Finally, evaluating the integral with respect to x, we obtain the final answer:

∫∫R dV = [from -1 to 1] ∫[from [tex]2x^2[/tex] to √(5-24+ [tex]y^2[/tex])] dy dx ≈ 20.2 cubic units.

Set up the definite integral required to find the area of the region between the graph of y = 15 – x² and Y 27x + 177 over the interval - 5 ≤ x ≤ 1. = dx 0

Answers

The area of the region between the two curves is 667 square units.

To find the area of the region between the graphs of \(y = 15 - x^2\) and \(y = 27x + 177\) over the interval \(-5 \leq x \leq 1\), we need to set up the definite integral.

The area can be calculated by taking the difference between the upper and lower curves and integrating with respect to \(x\) over the given interval.

First, we find the points of intersection between the two curves by setting them equal to each other:

\(15 - x^2 = 27x + 177\)

Rearranging the equation:

\(x^2 + 27x - 162 = 0\)

Solving this quadratic equation, we find the two intersection points: \(x = -18\) and \(x = 9\).

Next, we set up the definite integral for the area:

\(\text{Area} = \int_{-5}^{1} \left[(27x + 177) - (15 - x^2)\right] \, dx\)

Simplifying:

\(\text{Area} = \int_{-5}^{1} (27x + x^2 + 162) \, dx\)

Now, we can integrate term by term:

\(\text{Area} = \left[\frac{27x^2}{2} + \frac{x^3}{3} + 162x\right]_{-5}^{1}\)

Evaluating the definite integral:

\(\text{Area} = \left[\frac{27(1)^2}{2} + \frac{(1)^3}{3} + 162(1)\right] - \left[\frac{27(-5)^2}{2} + \frac{(-5)^3}{3} + 162(-5)\right]\)

Simplifying further:

\(\text{Area} = \frac{27}{2} + \frac{1}{3} + 162 + \frac{27(25)}{2} - \frac{125}{3} - 162(5)\)

Finally, calculating the value:

\(\text{Area} = \frac{27}{2} + \frac{1}{3} + 162 + \frac{675}{2} - \frac{125}{3} - 810\)

\(\text{Area} = \frac{27}{2} + \frac{1}{3} + \frac{486}{3} + \frac{675}{2} - \frac{125}{3} - \frac{2430}{3}\)

\(\text{Area} = \frac{900}{6} + \frac{2}{6} + \frac{2430}{6} + \frac{1350}{6} - \frac{250}{6} - \frac{2430}{6}\)

(\text{Area} = \frac{900 + 2 + 2430 + 1350 - 250 - 2430}{6}\)

(\text{Area} = \frac{4002}{6}\)

(\text{Area} = 667\) square units

In this case, [tex]\(h(x) = [g(x)]^3\)[/tex], so [tex]\(f(u) = u^3\)[/tex] where [tex]\(u = g(x)\).[/tex]

Taking the derivative of [tex]\(f(u) = u^3\)[/tex] with respect to [tex]\(u\)[/tex] gives [tex]\(f'(u) = 3u^2\)[/tex].

Applying the chain rule, we have [tex]\(h'(x) = f'(g(x)) \cdot g'(x) = 3[g(x)]^2 \cdot g'(x)\).[/tex]

Substituting [tex]\(x = 2\)[/tex], we get [tex]\(h'(2) = 3[g(2)]^2 \cdot g'(2)\).[/tex]

Using the given values in the table, [tex]\(g(2) = 8\) \\[/tex] and [tex]\(g'(2) = 3\)[/tex], so[tex]\(h'(2) = 3(8)^2 \cdot 3 = 3 \cdot 64 \cdot 3 = 576\)[/tex].

3n^2 - 5n + 2 = 2(3(n-1)^2 - 5(n-1) + 2) - (3(n-2)^2 - 5(n-2) + 2) + c.

Expanding and simplifying, we have:

3n^2 - 5n + 2 = 6n^2 - 18n + 14 - 3n^2 + 11n - 10 + c.

The arc length can be found by multiplying the radius by the central angle in radians, given the appropriate information.

To determine the arc length of a sector, we need to consider the given information for each case:

Given the radius of 14 cm, we need to find the central angle in radians. The arc length formula is s = rθ, where s represents the arc length, r is the radius, and θ is the central angle in radians.

To find the arc length, we can multiply the radius (14 cm) by the central angle in radians. Given the diameter of 18 ft, we can calculate the radius by dividing the diameter by 2. Then, we can use the same formula s = rθ, where r is the radius and θ is the central angle in radians.

The arc length can be found by multiplying the radius by the central angle in radians. Given the diameter of 7.5 meters and a central angle of 120°, we can first find the radius by dividing the diameter by 2.

Then, we need to convert the central angle from degrees to radians by multiplying it by π/180. Using the formula s = rθ, we can calculate the arc length by multiplying the radius by the central angle in radians.

Given the diameter, we need more specific information about the central angle in order to calculate the arc length.

In summary, to determine the arc length of a sector, we use the formula s = rθ, where s is the arc length, r is the radius, and θ is the central angle in radians.

2 Let f(x) = 3x - 7 and let g(x) = 2x + 1. Find the given value. f(g(3)]

Answers

The value of f(g(3)) is 14.

To find the value of f(g(3)), we need to evaluate the functions g(3) and then substitute the result into the function f.

First, let's find the value of g(3):

g(3) = 2(3) + 1 = 6 + 1 = 7.

Now that we have g(3) = 7, we can substitute it into the function f:

f(g(3)) = f(7).

To find the value of f(7), we need to substitute 7 into the function f:

f(7) = 3(7) - 7 = 21 - 7 = 14.

Therefore, the value of f(g(3)) is 14.

Given the functions f(x) = 3x - 7 and g(x) = 2x + 1, we are asked to find the value of f(g(3)).

To evaluate f(g(3)), we start by evaluating g(3). Since g(x) is a linear function, we can substitute 3 into the function to get g(3):

g(3) = 2(3) + 1 = 6 + 1 = 7.

Next, we substitute the value of g(3) into the function f. Using the expression f(x) = 3x - 7, we substitute x with 7:

f(g(3)) = f(7) = 3(7) - 7 = 21 - 7 = 14.

Therefore, the value of f(g(3)) is 14.

In summary, to find the value of f(g(3)), we first evaluate g(3) by substituting 3 into the function g(x) = 2x + 1, which gives us 7. Then, we substitute the value of g(3) into the function f(x) = 3x - 7 to find the final result of 14.

Solve the separable differential equation dy dt t t²y + y Use the following initial condition: y(0) = 5. Write answer as a formula in the variable t.

Answers

The solution to the differential equation with the given initial condition is: y(t) = 5/t.

To solve the separable differential equation

dy/dt = t/(t²y) + y,

we can rearrange the terms as:

dy/y = t/(t²y) dt + dt

Integrating both sides, we get:

ln|y| = -ln|t| + ln|y| + C

Simplifying, we get:

ln|t| = C

Substituting the initial condition y(0) = 5, we get:

ln|5| = C

Therefore, C = ln|5|

Substituting back into the equation, we get:

ln|y| = -ln|t| + ln|y| + ln|5|

Simplifying, we get: ln|y| = ln|5/t|

Taking the exponential of both sides, we get:

|y| = e^(ln|5/t|)

Since y(0) = 5, we can determine the sign of y as positive. Therefore, we have: y = 5/t

Thus, the solution to the differential equation with the given initial condition is: y(t) = 5/t.

The question should be:

The below dimensions represent the side measurements of triangles. Which one is not a right triangle?
A-6, 7, 8
B-3, 4, 5
C-9, 40, 41
D-16, 30, 34

Answers

Option A, with side measurements of 6, 7, and 8, is not a right triangle because it does not satisfy the Pythagorean theorem. The other options (B, C, and D) are right triangles since their side measurements satisfy the Pythagorean theorem.

To determine which triangle is not a right triangle, we need to check if the given side measurements satisfy the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

Let's calculate the values for each option:

A) Using the Pythagorean theorem: 6^2 + 7^2 = 36 + 49 = 85

Since 85 is not equal to 8^2 (64), option A is not a right triangle.

B) Using the Pythagorean theorem: 3^2 + 4^2 = 9 + 16 = 25

Since 25 is equal to 5^2 (25), option B is a right triangle.

C) Using the Pythagorean theorem: 9^2 + 40^2 = 81 + 1600 = 1681

Since 1681 is equal to 41^2 (1681), option C is a right triangle.

D) Using the Pythagorean theorem: 16^2 + 30^2 = 256 + 900 = 1156

Since 1156 is equal to 34^2 (1156), option D is a right triangle.

Based on the calculations, we can conclude that option A, with side measurements of 6, 7, and 8, is not a right triangle because it does not satisfy the Pythagorean theorem. The other options (B, C, and D) are right triangles since their side measurements satisfy the Pythagorean theorem.

Answers

The area of the lawn that receives water from the sprinkler is approximately 846.12 square feet. Thus, the correct option is d. 846.12 ft².

To find the area of the lawn that receives water from the sprinkler, we can calculate the area of the circular sector formed by the sprinkler's rotation.

The formula to calculate the area of a circular sector is given by:

Area = (θ/360°) × π × [tex]r^2[/tex]

where θ is the central angle in degrees, π is a mathematical constant approximately equal to 3.14159, and r is the radius of the circular pattern.

In this case, the central angle θ is given as 305°, and the radius r is 18 feet.

Plugging in these values into the formula:

Area = (305°/360°) × π × [tex](18 ft)^2[/tex]

Area = (305/360) × 3.14159 × 324

Area ≈ 0.847 × 3.14159 × 324

Area ≈ 846.12 ft²

Therefore, the area of the lawn that receives water from the sprinkler is approximately 846.12 square feet. Thus, the correct option is d. 846.12 ft².

The horizontal asymptotes of y = [tex]15x/(x^4 + 1)^(1/4)[/tex] are y1 = 0 and y2 = 0 (with y1 > y2). The vertical asymptote of y = [tex]-4x^3/(x + 6)[/tex] is x = -6.

To determine the horizontal asymptotes of the curve y =[tex]15x/(x^4 + 1)^(1/4),[/tex] we examine the behavior of the function as x approaches positive and negative infinity. As x becomes very large (approaching positive infinity), the denominator term[tex](x^4 + 1)^(1/4)[/tex] dominates the expression, and the value of y approaches 0. Similarly, as x becomes very large negative (approaching negative infinity), the denominator still dominates, and y also approaches 0. Therefore, y1 = 0 and y2 = 0 are the horizontal asymptotes, where y1 is greater than y2.

The vertical asymptote of the curve y = [tex]-4x^3/(x + 6)[/tex] can be found by setting the denominator equal to 0 and solving for x. In this case, when x + 6 = 0, x = -6. Thus, x = -6 is the vertical asymptote of the curve.

In summary, the horizontal asymptotes of y = [tex]15x/(x^4 + 1)^(1/4)[/tex] are y1 = 0 and y2 = 0 (with y1 > y2), and the vertical asymptote of y = [tex]-4x^3/(x + 6)[/tex] is x = -6.

Answers

We are given a vector field F = (3x - 5y)i + (5x - 3y)j and a curve C defined by the equation (x-4)^2 + (y-4)^2 = 16. We need to find the work done by F in moving a particle once counterclockwise around the curve.

The work done by a vector field F in moving a particle along a curve is given by the line integral of F along that curve. In this case, we need to evaluate the line integral ∮F · dr, where dr is the differential displacement vector along the curve.

To calculate the line integral, we can parameterize the curve C. Since C is a circle centered at (4, 4) with radius 4, we can use the parameterization x = 4 + 4cos(t) and y = 4 + 4sin(t), where t ranges from 0 to 2π.

Next, we calculate dr as the differential displacement vector along the curve:

dr = dx i + dy j = (-4sin(t))i + (4cos(t))j.

Substituting the parameterization and dr into the line integral ∮F · dr, we have:

∮F · dr = ∫[F(x, y) · dr] = ∫[(3x - 5y)(-4sin(t)) + (5x - 3y)(4cos(t))] dt.

Evaluating this integral over the range 0 to 2π will give us the work done by F in moving a particle once counterclockwise around the curve C.

Note: The detailed calculation of the line integral involves substituting the parameterization and performing the integration. Due to the length and complexity of the calculation, it is not possible to provide the exact numerical value in this text-based format.

Answers

Using the ratio test for the series ∑(k=1 to ∞) [(k+3)/k]^k, the series diverges. This is based on the ratio test, which shows that the limit of the absolute value of the ratio of consecutive terms is not less than 1, indicating that the series does not converge.

To determine whether the series ∑(k=1 to ∞) [(k+3)/k]^k converges or diverges, we can use the ratio test.

The ratio test states that if the limit of the absolute value of the ratio of consecutive terms is less than 1, then the series converges. If the limit is greater than 1 or it does not exist, then the series diverges.

Let's apply the ratio test to the given series:

Let a_k = [(k+3)/k]^k

We calculate the ratio of consecutive terms:

|a_(k+1)/a_k| = |[((k+1)+3)/(k+1)]^(k+1) / [(k+3)/k]^k|

Simplifying this expression, we get:

|a_(k+1)/a_k| = |[(k+4)(k+1)/[(k+1)+3)] * [(k+3)/k]^k|

Now, let's take the limit of this ratio as k approaches infinity:

lim(k→∞) |a_(k+1)/a_k| = lim(k→∞) |[(k+4)(k+1)/[(k+1)+3)] * [(k+3)/k]^k|

Simplifying this limit expression, we find:

lim(k→∞) |a_(k+1)/a_k| = lim(k→∞) |(k+4)(k+1)/(k+4)(k+3)| * lim(k→∞) |(k+3)/k|^k

Notice that lim(k→∞) |(k+4)(k+1)/(k+4)(k+3)| = 1, which is less than 1.

Now, we focus on the second term:

lim(k→∞) |(k+3)/k|^k = lim(k→∞) [(k+3)/k]^k = e^3

Since e^3 is a constant and it is greater than 1, the limit of this term is not less than 1.

Therefore, we have:

lim(k→∞) |a_(k+1)/a_k| = 1 * e^3 = e^3

Since e^3 is greater than 1, the limit of the ratio of consecutive terms is not less than 1.

According to the ratio test, if the limit of the ratio of consecutive terms is not less than 1, the series diverges.

Hence, the series ∑(k=1 to ∞) [(k+3)/k]^k diverges.

Assume b₁ = (-2/3), b₂ = (4/4), b₃ = (-6/5), b₄ = (8/6), and b₅ = (-10/7).

Since mod-bi < mod-b(i + 1) for all i implies that mode of the series.

(a). Evaluate the value of bₙ:

From given series,

-(2/3) + (4/4) - (6/5) + (8/6) - (10/7) + ...

Then, b₁ = (-2/3), b₂ = (4/4), b₃ = (-6/5), b₄ = (8/6), and b₅ = (-10/7).

So, bₙ = alpha ∑ (n = 1) {(-1)ⁿ 2n) / (n + 2)}

Thus, bₙ = {(-1)ⁿ 2n) / (n + 2)}.

(b). Evaluate the value of Limit:

lim (n = alpha) mod- bₙ = lim (n = alpha) {(2n) / (n + 2)}

Answers

The most helpful substitution for evaluating the given integral is option A: x = 14sinθ.

:

To evaluate the integral ∫dx/(196 - x^2)^2, we can use the trigonometric substitution x = 14sinθ. This substitution is effective because it allows us to express (196 - x^2) and dx in terms of trigonometric functions.

To find dx, we differentiate both sides of the substitution x = 14sinθ with respect to θ:

dx/dθ = 14cosθ

Rearranging the equation, we can solve for dx:

dx = 14cosθ dθ

Now, substitute x = 14sinθ and dx = 14cosθ dθ into the original integral:

∫dx/(196 - x^2)^2 = ∫(14cosθ)/(196 - (14sinθ)^2)^2 * 14cosθ dθ

Simplifying the expression under the square root and combining the constants, we have:

= ∫196cosθ/(196 - 196sin^2θ)^2 * 14cosθ dθ

= ∫196cosθ/(196 - 196sin^2θ)^2 * 14cosθ dθ

= 196 * 14 ∫cos^2θ/(196 - 196sin^2θ)^2 dθ

Now, we can proceed with integrating the new expression using trigonometric identities or other integration techniques.

find an equation of the plane.
The plane that contains the line x = 1 + 2t, y = t,z = 9 − t and

Answers

The equation of the plane that contains the line [tex]x = 1 + 2t, y = t, z = 9 - t,[/tex]and is parallel to the plane [tex]2x + 4y + 8z = 17[/tex] is [tex]2x + 4y + 8z = 11[/tex].

To find the equation of the plane, we first need to determine the direction vector of the line that lies in the plane.

From the given line equations, we can see that the direction vector is given by the coefficients of t in each component: (2, 1, -1).

Since the plane we want to find is parallel to the plane [tex]2x + 4y + 8z = 17[/tex], the normal vector of the plane we seek will be the same as the normal vector of the given plane. Therefore, the normal vector of the plane is (2, 4, 8).

To find the equation of the plane, we can use the point-normal form of the equation of a plane.

Since the plane contains the point (1, 0, 9) (which corresponds to t = 0 in the line equations), we can substitute these values into the point-normal form equation:

[tex]2(x - 1) + 4(y - 0) + 8(z - 9) = 0[/tex]

Simplifying the equation, we get:

[tex]2x + 4y + 8z = 11[/tex]

Hence, the equation of the plane that contains the given line and is parallel to the plane [tex]2x + 4y + 8z = 17[/tex] is [tex]2x + 4y + 8z = 11.[/tex]

Final answer:

Explanation:

In the given task, we need to find an equation of a plane that is parallel to another plane and also contains a given line. The first step is to understand that two parallel planes have the same normal vector. The equation of the plane 2x + 4y + 8z = 17, has a normal vector of (2,4,8). Our unknown plane parallel to this would also have this normal vector.

Then we need to find a point that lies on the plane containing the line. This can be any point on the line. So if we set t=0 in the line equation, we get the point (1,0,9) which also lie on the plane.

The equation of a plane given point (x0, y0, z0) and normal vector (a, b, c) is a(x - x0) + b(y - y0) + c(z - z0) = 0. So, if we plug our values, we get 2(x - 1) + 4(y - 0) + 8(z - 9) = 0, simplifying gives us 2x + 4y + 8z = 18 is the equation of the required plane.

y = y0 + bt

z = z0 + ct

Where (x0, y0, z0) is a point on the line (base point) and (a, b, c) are the components of the direction vector.

In this case, the base point is P0(-0,9) and the components of the vector from P0 to P2 are (23, -10, 1).

What is the differentiation of a function?

The differentiation of a function refers to the process of finding its derivative. The derivative of a function states the rate at which the function changes with respect to its independent variable.

  The derivative of a function f(x) with respect to the variable x is denoted as f'(x) or [tex]\frac{df}{dx}[/tex].

To differentiate the function [tex]g(t) = \frac{ln(t(t^2 + 1)^4}{5(8t - 1)}[/tex], we can apply the quotient rule and simplify the expression. Let's go through the steps:

Step 1: Apply the quotient rule to differentiate the function:

Let, [tex]f(t) = ln(t(t^2 + 1)^4)[/tex] and h(t) = 5(8t - 1).

The quotient rule states:

[tex]\frac{d}{dt} [\frac{f(t)}{ h(t)}] =\frac{ h(t) * f'(t) - f(t) * h'(t)}{ (h(t))^2}[/tex]

Step 2: Compute the derivatives:

Using the chain rule and the power rule, we can find the derivatives of f(t) and g(t) as follows:

[tex]f(t) = ln(t(t^2 + 1)^4)\\ f'(t) = \frac{1}{t(t^2 + 1)^4)} * (t(t^2 + 1)^4)'\\f'(t) =\frac{1 }{(t(t^2 + 1)^4} * (t * 4(t^2 + 1)^32t+ (t^2 + 1)^4 * 1) \\f'(t)=\frac{8t}{t^2+1}+\frac{1}{t}\\[/tex]

h(t) =5(8t-1)

h'(t) = 5 * 8

h'(t) = 40

Step 3: Substitute the derivatives into the quotient rule expression:

[tex]g(t) = \frac{ln(t(t^2 + 1)^4}{5(8t - 1)}[/tex] =[tex]\frac{ h(t) * f'(t) - f(t) * h'(t)}{ (h(t))^2}[/tex] =[tex]\frac{5(8t - 1)*(\frac{8t}{t^2+1}+\frac{1}{t})-ln(t(t^2+1)^4)*40}{(5(8-1))^2}\\[/tex]

Therefore, the differentiation of [tex]g(t) = \frac{ln(t(t^2 + 1)^4}{5(8t - 1)}[/tex] is:

[tex]\frac{d}{dt} (\frac{ln(t(t^2 + 1)^4} {5(8t - 1)})[/tex] =[tex]\frac{5(8t - 1)*(\frac{8t}{t^2+1}+\frac{1}{t})-ln(t(t^2+1)^4)*40}{(5(8-1))^2}\\[/tex]
