Find the slope of the curve y = x^3 -10x at the given point P(2, -12) by finding the limiting value of the slope of the secants through P. (b) Find an equation of the tangent line to the curve at P(2, - 12). (a) The slope of the curve at P(2, -12) is

Answers

Answer 1

The equation of the tangent line to the curve at P(2, -12) is y = 2x - 16.

(a) To find the slope of the curve y = x^3 - 10x at the given point P(2, -12), we need to find the derivative of the function y with respect to x, and then evaluate it at x = 2.

Step 1: Find the derivative, dy/dx
y = x^3 - 10x
dy/dx = 3x^2 - 10

Step 2: Evaluate the derivative at x = 2
dy/dx (2) = 3(2)^2 - 10 = 12 - 10 = 2

The slope of the curve at P(2, -12) is 2.

(b) To find an equation of the tangent line to the curve at P(2, -12), we'll use the point-slope form of the equation: y - y1 = m(x - x1).

Step 1: Use the slope found in part (a) and the given point P(2, -12).
m = 2
x1 = 2
y1 = -12

Step 2: Plug the values into the point-slope equation.
y - (-12) = 2(x - 2)
y + 12 = 2x - 4

Step 3: Rearrange the equation to get the final form.
y = 2x - 4 - 12
y = 2x - 16

The equation of the tangent line to the curve at P(2, -12) is y = 2x - 16.

Find the volume generated when the area bounded by the curve y?=x, the line x=4 and the
x-axis is revolved about the y-axis.

Answers

To find the volume generated, we need to use the formula for volume of revolution. We are revolving the area bounded by the curve y=x, the line x=4 and the x-axis about the y-axis.

First, we need to find the limits of integration for x. The curve y=x intersects the line x=4 at y=4, so we integrate from x=0 to x=4.

Next, we need to find the radius of the rotation. The radius is the distance from the y-axis to the curve at each value of x. Since we are revolving about the y-axis, the radius is simply x.

Using the formula for volume of revolution, we get:

V = π∫(radius)^2 dx from 0 to 4

V = π∫x^2 dx from 0 to 4

V = π[x^3/3] from 0 to 4

V = π[(4^3/3) - (0^3/3)]

V = (64π/3)

Therefore, the volume generated when the area bounded by the curve y=x, the line x=4 and the x-axis is revolved about the y-axis is (64π/3).
To find the volume generated when the area bounded by the curve y=x^2, the line x=4, and the x-axis is revolved around the y-axis, we'll use the disk method. The formula for the disk method is:

Volume = π * ∫ [R(x)]^2 dx

Here, R(x) is the radius function and the integral is taken over the given interval on the x-axis. In this case, R(x) = x and the interval is from 0 to 4.

Volume = π * ∫ [x]^2 dx, with the integral from 0 to 4

Now, we'll evaluate the integral:

Volume = π * [ (1/3)x^3 ](0 to 4)
Volume = π * [ (1/3)(4)^3 - (1/3)(0)^3 ]
Volume = π * [ (1/3)(64) - 0 ]
Volume = π * [ (64/3) ]

So, the volume generated is (64/3)π cubic units.

f has (select)(a relative minimum, a relative maximum, an absolute minimum, an absolute maximum, no extremum,) at (x, y) = ____________

Answers

The derivative of the given function is:

f'(t) = 12t^2 + 4

Setting f'(t) = 0 to find critical points, we get:

12t^2 + 4 = 0

t^2 = -1/3

This equation has no real solutions, which means there are no critical points on the interval [-2, 2]. Since the interval is closed and bounded, the function attains its maximum and minimum values at the endpoints of the interval.

We can find the values of the function at the endpoints:

f(-2) = -24

f(2) = 24

Therefore, the function has an absolute maximum of 24 at t = 2 and an absolute minimum of -24 at t = -2. There are no relative extrema.

Make d the subject of the formula t=4b²/21(d-3b/5)​

Answers

The formula for d is d = (t * 21/4b² + 3b)/5

To make d the subject of the formula t=4b²/21(d-3b/5), we need to isolate d on one side of the equation and simplify.

First, let's simplify the right side of the equation by multiplying the fraction by the LCD of 5:

t = 4b²/21(d-3b/5)

t = (4b²/21d) * 5d - 3b

Now, we can isolate d by dividing both sides of the equation by the coefficient of d on the right side:

t/(4b²/21) = 5d - 3b

Simplifying the left side, we get:

t * 21/4b² = 5d - 3b

Adding 3b to both sides of the equation, we get:

t * 21/4b² + 3b = 5d

Finally, we can divide both sides by 5 to isolate d:

d = (t * 21/4b² + 3b)/5

Therefore, the formula for d is:

d = (t * 21/4b² + 3b)/5

In words, to find the value of d, we need to multiply the value of t by 21/4b², add 3b to the result, and divide the sum by 5.

If we were going to reflect it over the y-axis by counting the distance it is from the y-axis and counting it in the other direction. When we do this we get a point of (7,1).

Transformations and Congruence:Question 3 Triangle ABC is reflected over the x-axis. Which is the algebraic rule applied to the figure? Select one:​

Answers

Hi! I'd be happy to help you with your question about transformations and congruence. When Triangle ABC is reflected over the x-axis, the algebraic rule applied to the figure is:

Your answer: (x, y) → (x, -y)

This rule states that the x-coordinate remains the same, while the y-coordinate is multiplied by -1, resulting in a reflection over the x-axis. This transformation preserves congruence, as the size and shape of Triangle ABC remain the same, only its position changes.

The algebraic rule applied to the figure when Triangle ABC is reflected over the x-axis is (x,y) → (x,-y), where x represents the x-coordinate and y represents the y-coordinate. This is because reflecting a figure over the x-axis involves keeping the x-coordinate the same while changing the sign of the y-coordinate.

EXAMPLE 1 A spring with a mass of 6 kg has a natural length of 0.3 m. A force of 38.4 N is required to maintain it stretched to a length of 0.7 m. If the spring is stretched to a length of 0.7 m and then released with initial velocity 0, find the position of the mass at time t. SOLUTION From Hooke's Law, the force required to stretch the spring is k(0.4) = 38.4 so k = 38.4/0.4 = 96.

The equation given in the solution is X(t) = (cos(4t) + C2sin(4t)). This equation represents the position of the mass at time t after the spring has been released with an initial velocity of 0. The terms "spring" and "stretch" indicate that Hooke's Law is being used to determine the spring constant k.

The term "velocity" is used to describe the initial velocity of the mass, which is given as 0. The position of the mass at time t is determined by the value of X(t), which is a function of time. Therefore, the position of the mass at any given time can be found by plugging in the value of t into the equation X(t) = (cos(4t) + C2sin(4t)).
Hi! Based on the information provided, you have a spring with a mass of 6 kg and a natural length of 0.3 m. A force of 38.4 N is required to stretch it to 0.7 m.

Marshall and oliver went to an arcade where the machines took tokens. marshall played 10 games of skee ball and 8 games of pinball, using a total of 44 tokens. at the same time, oliver played 3 games of skee ball and 8 games of pinball, using up 30 tokens. how many tokens does each game require?

Answers

Each game of skee ball requires 2 tokens and each game of pinball requires 2 tokens.

Let the number of tokens required for each game of skee ball be x and for each game of pinball be y.

From the given information, we can form two equations:

10x + 8y = 44    ... (1)

3x + 8y = 30      ... (2)

Multiplying equation (2) by 3, we get:

9x + 24y = 90     ... (3)

Subtracting equation (1) from equation (3), we get:

- x + 16y = 46

Solving for x, we get:

x = 16y - 46

Substituting this value of x in equation (2), we get:

3(16y - 46) + 8y = 30

Simplifying and solving for y, we get:

y = 2

Substituting this value of y in equation (1), we get:

10x + 8(2) = 44

Solving for x, we get:

x = 2

Therefore, each game of skee ball requires 2 tokens and each game of pinball requires 2 tokens.

The correct statement that compares the value of the 6 in 26.495 and 17.64 is the value of the 6 in 26.495 is 10 times the value of the 6 in 17.64. Therefore, the correct option is D.

This is because the value of a digit is determined by its place in the number. In 26.495, the 6 is in the tenths place, which means it represents 6/10 or 0.6. In 17.64, the 6 is in the hundredths place, which means it represents 6/100 or 0.06. Therefore, the value of the 6 in 26.495 is 0.6 and the value of the 6 in 17.64 is 0.06.

To compare these values, we can divide the value of the 6 in 26.495 by the value of the 6 in 17.64. This gives us 0.6/0.06 = 10. Therefore, the value of the 6 in 26.495 is 10 times greater than the value of the 6 in 17.64 which corresponds to option D.

The graph of line (1) is present in above figure. Slope intercept form of equation (1) is written as [tex]y = - \frac{1}{2}x + \frac{5}{2}[/tex],

The x-intercept is point where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. As we know, two points determine any line, we can graph lines using the x- and y-intercepts. To determine the x-intercept, we substitute y=0 and solve for x. So, when y = 0 then 4x + 0 = 20

it has a 15% yearly interest rate.
the interest is compounded monthly.
the card has $0 minimum payments for the first four years it is active.

Answers

If it has a 15% yearly interest rate and the interest is compounded monthly and the card has $0 minimum payments for the first four years it is active. Therefore, Emma will owe approximately $529.27 in four years.

To calculate how much Emma will owe in four years, we need to use the compound interest formula: A = P (1 + r/n)^(n*t)

where:

A = the amount of money at the end of the investment period

P = the principal amount (the initial amount of money borrowed)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time period in years

In this case, the principal amount is $300, the annual interest rate is 15%, and the interest is compounded monthly (so n = 12). The time period is four years.

Plugging in the values, we get:

A = 300(1 + 0.15/12)^(12*4)

A ≈ $529.27

Therefore, Emma will owe approximately $529.27 in four years if she doesn't pay off her credit card until after college.

If i walked 14 out of the 20 days in February, which value is equivalent to the fraction of the school days in February that i walked to school?

Answers

The fraction of the school days in February that you walked to school is 7/10 or 0.7 when expressed as a decimal.

What is the fraction of school days in February that you walked to school if you walked 14 out of 20 days?

The fraction of the school days in February that you walked to school can be represented as:

(number of days you walked) / (total number of school days in February)

Since you walked 14 out of 20 days in February, we can substitute these values into the formula:

(number of days you walked) / (total number of school days in February) = 14 / 20

Simplifying the fraction by dividing both the numerator and denominator by their greatest common factor (2), we get:

(number of days you walked) / (total number of school days in February) = 7 / 10

3. Suppose a simple random sample of 150 college students is drawn. Among sampled students, the average IQ score is 115 with a standard deviation of 10. What is the 95% confidence interval for the ents^ prime IQ score?

Answers

Answer: is approximately between 113.39 and 116.61
To calculate the 95% confidence interval for the students' average IQ score, we'll use the given information: sample size (n=150), sample mean (X=115), and sample standard deviation (s=10). We'll use the t-distribution since the population standard deviation is unknown.

First, we need to find the t-value for a 95% confidence interval with n-1 (149) degrees of freedom. Using a t-table or calculator, we find the t-value to be approximately 1.976.

Next, we'll calculate the standard error (SE) using the formula: SE = s/√n. In this case, SE = 10/√150 ≈ 0.816.

Now, we can find the margin of error (ME) using the formula: ME = t-value × SE. For this problem, ME = 1.976 × 0.816 ≈ 1.61.

Finally, to calculate the 95% confidence interval, we'll use the formula: X ± ME. Thus, the 95% confidence interval is 115 ± 1.61, which is approximately (113.39, 116.61).

So, the 95% confidence interval for the students' average IQ score is approximately between 113.39 and 116.61.

How much would it cost to buy a cover for the pool that cost $0.30 per square foot

Answers

It would cost $735 to buy a cover for the pool at $0.30 per square foot

How much would it cost to buy a cover for the pool

From the complete question (see attachment), we have the following parameters that can be used in our computation:

Unit rate = $0.30 per square foot

Dimensions = 10 inches by 20 inches

Scale = 2 inches : 7 feet

Using the above as a guide, we have the following:

Total cost = Unit rate * Area of pool

Where

Area of the pool = 10 inches * 20 inches

Using the scale, we have

Area of the pool = (10 * 7/2)* (20 * 7/2) square feet

Area of the pool = 2450 square feet

Substitute the known values in the above equation, so, we have the following representation

Total cost = $0.30 per square feet * 2450 square feet

This gives

Total cost = $735

Hence, it would cost $735 to buy a cover for the pool

Given that segment KL is parallel to segment MN and that segment KN bisects segment ML, prove that segment KO is congruent to segment NO

Answers

If that segment KL is parallel to segment MN and that segment KN bisects segment ML, then segment KO is congruent to segment NO.

To prove that segment KO is congruent to segment NO, we need to show that triangle KNO is an isosceles triangle, with KO ≅ NO.

From the given information, we know that KL is parallel to MN, which means that angle KLN is congruent to angle MNL (corresponding angles). Also, KN bisects segment ML, which means that angle KNO is congruent to angle NMO (angle bisector theorem).

Therefore, we have:

angle KNO = angle NMO

angle KLN = angle MNL

Adding these two equations gives us:

angle KNO + angle KLN = angle NMO + angle MNL

But angle KLN + angle NMO + angle MNL = 180 degrees (as they form a straight line). So we can substitute this into the equation:

angle KNO + 180 degrees = 180 degrees

Simplifying, we get:

angle KNO = 0 degrees

This means that KO and NO are on the same line, so they must be congruent. Therefore, we have proven that segment KO is congruent to segment NO.

A food company is designing box for several products each box is a rectangular prism. The food company is now designing soup boxes. The largest box of soup will be a dilation of the smallest box using a scale factor of two. The smallest box must hold eight fluid ounces or about 15 in. ³ of soup. Find a set of dimensions for the largest box round to the nearest tenth

Answers

The set of dimensions for the largest box is: 4 in x 4 in x 3.8 in.

We know that the smallest box must hold 8 fluid ounces or 15 in³ of soup. Let's assume the dimensions of the smallest box to be x, y, and z.

Then, we have:

[tex]x * y * z = 15[/tex]

Now, the largest box will be a dilation of the smallest box using a scale factor of 2. This means that every dimension of the smallest box will be multiplied by 2 to get the dimensions of the largest box.

So, the dimensions of the largest box will be 2x, 2y, and 2z.

Now, we need to find the dimensions of the smallest box. We can start by solving the equation x * y * z = 15 for one of the variables, say z:

[tex]z = 15 / (x * y)[/tex]

Substituting this value of z in the expression for the dimensions of the largest box, we get:

[tex]2x * 2y * (15 / (x * y))[/tex]

Simplifying this expression, we get:

[tex]4 * 15 = 60[/tex]

So, the dimensions of the largest box are approximately 4 in by 4 in by 3.8 in (rounded to the nearest tenth).

Therefore, the set of dimensions for the largest box is: 4 in x 4 in x 3.8 in.

Nevertheless, he remained deeply attached to his native Catalonia, and returned each summer to his family's farm in the village of Montroig. In 1921, he determined to make a painting of this farm, a painting that he came to regard as one of the key works in his career.The Farm represents a brilliant amalgamation of an intense, even primitive realism with the formal vocabulary of cubism. The painting is a compendium of separate details, each carefully observed and precisely described. This detailed realism, however, is matched by a tendency to simplify forms into abstract, geometric shapes.Moreover, space in The Farm is defined by a ground plane that tilts sharply upward, while individual forms are similarly tilted, so that they sit silhouetted, parallel to the picture plane.By the mid-1920s, Miro had abandoned the realist manner of The Farm and had created a surrealist style of automatism and abstraction.Elements from The Farm continued to appear in his work, however, and the intensity of vision found in this painting remained a standard for all of his later art.Website: https://www.nga.gov/collection/art-object-page.69660.htmlQuestion: Size & Effect of SizeWhat is the size of the work?
