The scale factor and the perimeters are = 1/2 and 34 and 17 units.

Given that are two polygons are similar MNPQ ~ XYZW, we need to find the scale factor and the perimeter of each polygon.

Scale factor = ratio of the lengths of the sides of the similar polygons.

Scale factor = MQ / WX = 8/4 = 2

Now,

The perimeter of the polygon XYZW = 10 + 9 + 8 + 7 = 34 units.

We know that the ratio of the perimeters of the similar polygons is equal to the scale factor,

So,

The perimeter of the polygon MNPQ = 34 / 2 = 17 units.

Hence the scale factor and the perimeters are = 1/2 and 34 and 17 units.

Answer:

  7) compare what Jason needed to do with what he did

  8) Jason used an incorrect formula to estimate his need

  9) an overestimate ensures Jason can finish the job

Step-by-step explanation:

7) A critique is a comparison of what you have with what you expect. We can critique Jason's reasoning by comparing what he did with what we expected him to do. (We don't actually know his reasoning; we only know his action.)

__

8) Jason multiplied the dimensions of his room, an action appropriate to finding its area. We expected that Jason would use a formula for the perimeter of the room. We conclude that Jason chose the wrong formula for computing the length of border needed. We also note that Jason did not make any use of dimensional analysis. Had he done so, he would have known that his result was in square feet, not linear feet, so was not applicable to the question of whether he had enough border.

The test statistic value for this situation is approximately -2.474.

A hypothesis test comparing the sample mean to the assumed population mean is necessary in order to determine the value of the test statistic. The population mean triglycerides level would be the null hypothesis (H0), and the alternative hypothesis (Ha) would be that the population mean is not 130 units.

The t-statistic, which is calculated as follows, is the test statistic utilized in this circumstance:

t = (test mean - expected populace mean)/(test standard deviation/sqrt(sample size))

Given the data gave, we have:

Expected populace mean (μ): 130 Mean of the sample (x): 122

Test standard deviation (s): 20 (n) sample sizes: 30

Connecting the qualities into the recipe, we can work out the test measurement:

t = (122 - 130) / (20 / sqrt(30)) t = -8 / (20 / sqrt(30)) After calculating this expression, we come to the following conclusion:

t ≈ - 2.474

Hence, the test measurement an incentive for this present circumstance is roughly - 2.474.

To find the probability of getting 10 or more successes in a binomial experiment with p = 0.63 and n = 11 trials, we can use the cumulative probability function.

P(X ≥ 10) = 1 - P(X < 10)

Using a binomial probability formula, we can calculate the probability of getting exactly k successes:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

where C(n, k) represents the binomial coefficient.

Let's calculate the probability for each value from 0 to 9 and subtract it from 1 to get the probability of 10 or more successes:

P(X < 10) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 9)

P(X < 10) = Σ[C(11, k) * p^k * (1 - p)^(11 - k)] for k = 0 to 9

Using this formula, we can calculate the probability:

P(X < 10) ≈ 0.121

Therefore, the probability of getting 10 or more successes in the binomial experiment is:

P(X ≥ 10) ≈ 1 - P(X < 10) ≈ 1 - 0.121 ≈ 0.879

Rounding to three decimal places, the probability is approximately 0.879.

The solution is:

Step-by-step explanation:

First, we'll calculate the function's average rate of change over [-1,1] as following:

Now, we make f'(x) = 3 and solve for x, as following:

Therefore, we can conlcude that the solution is:

By applying rate of change concept it can be concluded that the area will change at a rate of 176 cm² / minute.

Rate of change is the change in values of a dependent variable concerning the independent variables.

The rate of change of a function shows how the function is changing from one x value to another. Whilst, differentiation is when you have an instantaneous rate of change at a single point.

We have the following information:

The rate of change of a circle = 7 cm/minute = dr/dt

We have to find the rate of change of the circle when r = 4 cm

To do so, we will use the derivative of the circle area:

A = πr²

dA/dr = 2πr

dA/dt = dA/dr × dr/dt

         = 2πr × 7  

         = 14πr

Now we input r = 4 cm into this equation:

rate of change of the area =  14*22/7*4

                                            =  176 cm² / minute

Thus, when r = 4 cm, the area will change at a rate of 176 cm² / minute.

yes, actually it is possible. The mathematical expression f(x)=exp or ex denotes the exponential function.

The mathematical expression f(x)=exp or ex denotes the exponential function. The word, unless specifically stated differently, normally refers to the positive-valued function of a real variable, though it can be extended to the complex numbers or adapted to other mathematical objects like matrices or Lie algebras. When the input variable x appears as an exponent in the formula f(x) = axe, an exponential function is indicated. The exponential curve is influenced by both the exponential function and the value of x.

One of the key mathematical operations is the exponential function (though it would have to admit that the linear function ranks even higher in importance). We allow the exponent to be the independent variable to create an exponential function. The formula f(x)=2x is a straightforward example.

Hence, yes, actually it is possible.

The flux of f across the surface s is 0.

To find the flux of f across the surface s, we can use the formula for flux:
flux = ∬(f · dS)
where f is the vector field, dS is the differential surface area vector, and the double integral is taken over the surface s.

In this case, f = j, which means the vector field is constant in the z-direction with a magnitude of 1. Therefore, the flux simplifies to:
flux = ∬(j · dS)

Now, let's calculate the flux step-by-step:
1. First, we need to parametrize the surface s. Since s is the part of the plane z=1 x y inside the cylinder x^2 + y^2 = 1, we can parametrize it as:
r(u, v) = (u, v, 1), where -1 ≤ u, v ≤ 1

2. Next, we need to find the differential surface area vector dS. Since s is a plane, the differential surface area vector is simply the cross product of the partial derivatives of r with respect to u and v:
dS = (∂r/∂u) × (∂r/∂v)

Calculating the cross product, we get:
dS = (1, 0, 0) × (0, 1, 0) = (0, 0, 1)

3. Now, let's evaluate the double integral ∬(j · dS) over the surface s. Since the magnitude of j is 1 and the dot product of j and dS is always 0, the flux is always 0.

Therefore, Flux of f across the surface s is 0.

Answer:

266.666667

Step-by-step explanation:

1) The general solution to the differential equation is y = K\(e^{-1 / x\)

2) The general solution is (1/2)\(x^2\)y - (1/3)\(x^2\)\(y^3\) = (1/3)\(x^3\) + (1/3)\(y^3\) + y + C.

1) To obtain the general solution of the differential equation \(x^2\)yy' = \(e^y\), we can use separation of variables.

Start by rearranging the equation:

yy' = \(e^y\)/ \(x^2\)

Next, separate the variables:

(1 / y) dy = (\(e^y\) / \(x^2\)) dx

Now, integrate both sides:

∫(1 / y) dy = ∫(\(e^y\) / \(x^2\)) dx

The integral on the left side can be evaluated as ln|y|, and the integral on the right side can be evaluated using the substitution u = \(e^y\):

ln|y| = ∫(1 / \(x^2\)) du

ln|y| = -1 / x + C

Where C is the constant of integration.

Finally, exponentiate both sides to solve for y:

|y| = \(e^{-1 / x + C\)

|y| = \(e^C\) / \(e^{1 / x\)

|y| = K\(e^{-1 / x\)

Where K = ±\(e^C\) is the constant of integration.

Therefore, the general solution to the differential equation is:

y = K\(e^{-1 / x\)

2) To obtain the general solution of the differential equation (xy + x)dx = (\(x^2y^2\) + \(x^2\) + \(y^2\) + 1)dy, we'll again use separation of variables.

Start by rearranging the equation:

(xy + x)dx - (\(x^2y^2\) + \(x^2\) + \(y^2\) + 1)dy = 0

Next, separate the variables:

(xy + x)dx = (\(x^2y^2\) + \(x^2\) + \(y^2\) + 1)dy

Now, integrate both sides:

∫(xy + x)dx = ∫(\(x^2y^2\) +\(x^2\) + \(y^2\) + 1)dy

Integrating each term separately:

∫xy dx + ∫x dx = ∫\(x^2y^2\) dy + ∫\(x^2\) dy + ∫\(y^2\) dy + ∫1 dy

Integrating, we get:

(1/2)\(x^2\)y + (1/2)\(x^2\) = (1/3)\(x^2y^3\) + (1/3)\(x^3\) + (1/3)\(y^3\) + y + C

Where C is the constant of integration.

Simplifying and rearranging, we obtain the general solution:

(1/2)\(x^2\)y - (1/3)\(x^2\)\(y^3\) = (1/3)\(x^3\) + (1/3)\(y^3\) + y + C

This is the general solution to the given differential equation.
