d = 5 for PQ

For:

(X1, Y1) = (0, 0)

(X2, Y2) = (5, 0)

finding distance between two points

d=√(5−0)^2+(0−0)^2

d=√(5)^2+(0)^2

d=√25+0

d=√25

d=5

for RS d=3

d = 3

For:

(X1, Y1) = (3, 2)

(X2, Y2) = (0, 2)

d=√(0−3)^2+(2−2)^2

d=√(−3)^2+(0)^2

d=√9+0

d=3

Answer:

False. All triangles must have a total of 180°. 60° + 60° + 70° = 190°.

The solution to this system of linear equations y - x = 6 and y + x = -10 is (-8, -2).

y - x = 6

⇒y = x + 6

y + x = -10

⇒y = - x - 10

Since both equations are equal to y, equate them.

x + 6 = - x - 10

x + x = - 10 - 6

2x = - 16

Divide both sides by 2

x = -8

Put the value of x in either of the equations

y - x = 6

y - (-8) = 6

y + 8 = 6

y = 6 - 8

y = - 2

Therefore, the solution to the system of linear equations is (-8, -2).

Step-by-step explanation:

The mean and standard deviation of the sampling distribution of p are μp = 0.42 and σp = 0.0868, respectively.

Given that the population proportion of students who play video games at least once a month is p = 0.42 and the sample size is n = 30.

The mean of the sampling distribution of the sample proportion is given by:

μp = p = 0.42

The standard deviation of the sampling distribution of the sample proportion is given by:

σp = sqrt[p(1-p)/n] = sqrt[(0.42)(0.58)/30] ≈ 0.0868

Therefore, the mean and standard deviation of the sampling distribution of p are μp = 0.42 and σp = 0.0868, respectively.

A random sample taken with replacement from the original sample, and having the same size as the original sample, is known as a "bootstrap sample" or "bootstrap replication."

Bootstrapping is a resampling technique used to estimate the sampling distribution of a statistic. When we have a limited sample size and want to draw inferences about the population, we can use bootstrapping to create multiple resamples by randomly selecting observations from the original sample with replacement.

Here's how it works:

The key idea behind bootstrapping is that the original sample serves as a proxy for the population, and by repeatedly resampling from it, we can approximate the sampling distribution of the statistic of interest. This approach is especially useful when the underlying population distribution is unknown or non-normal.

By using a bootstrap sample that is the same size as the original sample, we maintain the same sample size and capture the variability present in the original data.

The derivative of the vector function r(t) = ⟨6t, t^2, 1/9t^3⟩ is r'(t) = ⟨6, 2t, t^2⟩.

To find the derivative of a vector function, we differentiate each component of the vector with respect to the variable, which in this case is t. Taking the derivative of each component of r(t), we get:

The derivative of 6t with respect to t is 6, as the derivative of a constant multiple of t is the constant itself.

The derivative of t^2 with respect to t is 2t, as we apply the power rule which states that the derivative of t^n is n*t^(n-1).

The derivative of (1/9t^3) with respect to t is (1/9) * (3t^2) = t^2/3, as we apply the power rule and multiply by the constant factor.

Combining the derivatives of each component, we obtain r'(t) = ⟨6, 2t, t^2⟩. This represents the derivative vector of the original vector function r(t).

Answer:

height = 16.5 feet

Step-by-step explanation:

Givens

Start by drawing a right angle triangle. The hypotenuse is 36 and the side adjacent to where the ladder meets the ground is the adjacent side. The tallest part of the building is found from the Pythagorean Theorem.

Givens

Hypotenuse = 36

Adjacent = 32

Height = ?

Formula

a^2 + b^2 = c^2

c is the ladder length

a = 32

b = ?

Solution

32^2 + b^2 = 36^2

1024 + b^2 = 1296             Subtract 1024 from both sides

b^2 = 1296-1024

b^2 = 272                           Take the square root of both sides.

sqrt(b^2) = sqrt(272)

b = 16.49

Subtract 4 from 34, now divide by 3.  Combine product by number of boys.

The change in average cost is approximately 11.98 dollars.

To estimate the change in average cost as production goes from 250 units to 251 units, we need to calculate the difference between A(251) and A(250).

A(250) = 12(250) + 1250/250 = 300 + 5 = 305

A(251) = 12(251) + 1250/251 = 301.03

Therefore, the change in average cost is approximately:

A(251) - A(250) = 301.03 - 305 = -3.97 dollars (rounded to two decimal places)

So the change in average cost is approximately negative 3.97 dollars.

To estimate the change in average cost as production goes from 250 units to 251 units, we need to find the difference between the average cost at 251 units and the average cost at 250 units using the given function A(x) = 12x + 1250/x.

First, find the average cost for 250 units:
A(250) = 12(250) + 1250/250 = 3000 + 5 = 3005 dollars.

Next, find the average cost for 251 units:
A(251) = 12(251) + 1250/251 ≈ 3012 + 4.98 ≈ 3016.98 dollars.

Now, find the change in average cost:
Change = A(251) - A(250) ≈ 3016.98 - 3005 = 11.98 dollars.

The change in average cost is approximately 11.98 dollars.

The lines AB and CD are parallel lines.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The slope of line AB is m=2+1/-4+8

The line integral ∫[C] (Pdx + Qdy) over the given curve C consisting of the arc of the parabola y = x² from (0,0) to (1, 1), and the line segment from (1,1) to (0,1) is equal to 2/5.

What is integral?

The value obtained after integrating or adding the terms of a function that is divided into an infinite number of terms is generally referred to as an integral value.

To evaluate the line integral using Green's theorem, we need to find a vector field F = (P, Q) such that ∇ × F = Qₓ - Pᵧ, where Qₓ represents the partial derivative of Q with respect to x, and Pᵧ represents the partial derivative of P with respect to y.

Let's consider F = (P, Q) = (x²y², xy).

Now, let's calculate the partial derivatives:

Qₓ = ∂Q/∂x = ∂(xy)/∂x = y

Pᵧ = ∂P/∂y = ∂(x²y²)/∂y = 2x²y

The curl of F is given by ∇ × F = Qₓ - Pᵧ = y - 2x²y = (1 - 2x²)y.

Now, let's find the line integral using Green's theorem:

∫[C] (Pdx + Qdy) = ∫∫[R] (1 - 2x²)y dA,

where [R] represents the region enclosed by the curve C.

To evaluate the line integral, we need to parameterize the curve C.

The arc of the parabola y = x² from (0, 0) to (1, 1) can be parameterized as r(t) = (t, t²) for t ∈ [0, 1].

The line segment from (1, 1) to (0, 1) can be parameterized as r(t) = (1 - t, 1) for t ∈ [0, 1].

Using these parameterizations, the region R is bounded by the curves r(t) = (t, t²) and r(t) = (1 - t, 1).

Now, let's calculate the line integral:

∫∫[R] (1 - 2x²)y dA = ∫[0,1] ∫[t²,1] (1 - 2t²)y dy dx + ∫[0,1] ∫[0,t²] (1 - 2t²)y dy dx.

Integrating with respect to y first:

∫[0,1] [(1 - 2t²)(1 - t²) - (1 - 2t²)t²] dt.

Simplifying:

∫[0,1] [1 - 3t² + 2t⁴] dt.

Integrating with respect to t:

[t - t³ + (2/5)t⁵]_[0,1] = 1 - 1 + (2/5) = 2/5.

Therefore, the line integral ∫[C] (Pdx + Qdy) over the given curve C consisting of the arc of the parabola y = x² from (0,0) to (1,1), and the line segment from (1,1) to (0,1) is equal to 2/5.
