Answer:

C

Step-by-step explanation:

An equation is where you already have the answer but you have to find out what the variable is to prove that the equation is true.

However, we need to substitute a with s since that is the value we have calculated. Therefore, we get \(A(s) = (1/4)(5 + sqrt(5))s^2.\) This is the function notation that represents the area of a regular pentagon whose perimeter is 140 cm.

Let's consider that s be the length of a side of the regular pentagon.

The perimeter of the regular pentagon will be 5s. Therefore, we have the equation:5s = 140s = 28 cm

Also,

we have the formula for the area of a regular pentagon as:

\($A=\frac{1}{4}(5 +\sqrt{5})a^{2}$,\)

where a is the length of a side of the pentagon.

In order to represent the area of a regular pentagon whose perimeter is 140 cm, we need to substitute a with s, which we have already calculated.

Therefore, we have:\(A(s) = $\frac{1}{{4}(5 +\sqrt{5})s^{2}}$\)

Now, we have successfully used function notation (with the appropriate functions above) to represent the area of a regular pentagon whose perimeter is 140 cm.

The area of a regular pentagon can be represented using function notation (with the appropriate functions above). The first step is to calculate the length of a side of the regular pentagon by dividing the perimeter by 5, since there are 5 sides in a pentagon.

In this case, we are given that the perimeter is 140 cm, so we get 5s = 140, which simplifies to s = 28 cm. We can now use the formula for the area of a regular pentagon, which is\(A = (1/4)(5 + sqrt(5))a^2\), where a is the length of a side of the pentagon.

However, we need to substitute a with s since that is the value we have calculated. Therefore, we get\(A(s) = (1/4)(5 + sqrt(5))s^2.\) This is the function notation that represents the area of a regular pentagon whose perimeter is 140 cm.

Answer:

minimum for given function C=10,000x + 20,000y is 67,380.

Step-by-step explanation:

Answer:

C0 = 1, C1 = -20x^2, C2 = 100x^4, C3 = -666.67x^6, C4 = 6666.67x^8.

Step-by-step explanation:

We can use the Maclaurin series formula for the exponential function and then multiply the resulting series by 4x^2 to obtain the series for (4x^2)*e^(-5x):e^(-5x) = ∑(n=0 to ∞) (-5x)^n / n!

Multiplying by 4x^2, we get:

(4x^2)*e^(-5x) = ∑(n=0 to ∞) (-20x^(n+2)) / n!

To get the coefficients C0 to C4, we substitute n = 0 to 4 into the above series and simplify:

C0 = (-20x^2)^0 / 0! = 1

C1 = (-20x^2)^1 / 1! = -20x^2

C2 = (-20x^2)^2 / 2! = 200x^4 / 2 = 100x^4

C3 = (-20x^2)^3 / 3! = -4000x^6 / 6 = -666.67x^6

C4 = (-20x^2)^4 / 4! = 160000x^8 / 24 = 6666.67x^8

Therefore, the Maclaurin series for (4x^2)*e^(-5x) and its coefficients C0 to C4 are:

(4x^2)*e^(-5x) = 1 - 20x^2 + 100x^4 - 666.67x^6 + 6666.67x^8 + O(x^9)

C0 = 1, C1 = -20x^2, C2 = 100x^4, C3 = -666.67x^6, C4 = 6666.67x^8.

Answer:

3 feet :)

Step-by-step explanation:

To find the height of the create, you can use the formula for volume of a rectangular prism, which is V = lwh, where V is the volume, l is the length, w is the width, and h is the height. Since you are given the volume and the base area, you can solve for the height using the following steps:

Substitute the given values into the formula for volume: V = lwh = 48 cubic feet.

Substitute the given value for the base area: lw = 16 square feet.

Solve for the length by dividing the base area by the width: l = 16/w.

Substitute the expression for length from Step 3 into the formula for volume in Step 1: V = 16h/w.

Solve for the height by multiplying both sides of the equation by w/16 and simplifying: h = V/(16/w) = Vw/16.

Therefore, the height of the crate can be calculated as h = 48/16 = 3 feet.

Hi how are you doing Jasmine

The dot product of a~ and b~ is -12.98. To find the dot product of vectors a~ and b~, we need to calculate the product of their corresponding components. Given that vector a~ is 2.07 units long and points in the positive y direction, and vector b~ has a negative x component (-6.29 units), a positive y component (2.17 units), and no z component, we can determine their dot product.

The dot product of two vectors is found by multiplying their corresponding components and summing the results. In this case, vector a~ has no x or z component, so we only need to consider the y component. Since a~ points in the positive y direction and has a magnitude of 2.07 units, its y component is 2.07.

Vector b~ has a negative x component of -6.29 units and a positive y component of 2.17 units. Since there is no z component mentioned, we can assume it is zero.

To find the dot product, we multiply the corresponding components of a~ and b~: \(a_y \cdot b_x + a_y \cdot b_y + a_y \cdot b_z = 2.07 \cdot 0 + 2.07 \cdot (-6.29) + 2.07 \cdot 0 = -12.98\).

Therefore, the dot product of a~ and b~ is -12.98.

The value of variance in the above formula: σ(X) = √(b-a) / √12. This is our standard deviation (σ(X)).

The probability density function, over the given interval, can be found using the formula below:  

f(x) = 1 / (b - a) over [a, b]

Let's start with finding the expected value (E(X)).

Formula for E(X):

E(X) = ∫xf(x)dx over [a, b]

We can substitute f(x) with the formula we obtained in the question.  

E(X) = ∫x(1/(b-a))dx over [a, b]

Next, we can solve the above integral.

E(X) = [x²/2(b-a)] between limits a and b, which simplifies to:

E(X) = [b² - a²] / 2(b-a)  = (b+a)/2

This is our expected value (E(X)).

Next, we will find the expected value (E(X²)).

Formula for E(X²):E(X²) = ∫x²f(x)dx over [a, b]

Substituting f(x) in the above formula: E(X²) = ∫x²(1/(b-a))dx over [a, b]

Solving the above integral, we get:

E(X²) = [x³/3(b-a)] between limits a and b

E(X²) = [b³ - a³] / 3(b-a)  

= (b² + ab + a²) / 3

This is our expected value (E(X²)).

Now we can find the variance and standard deviation.

Variance: Var(X) = E(X²) - [E(X)]²

Substituting the values we have found:

Var(X) = (b² + ab + a²) / 3 - [(b+a)/2]²

Var(X) = (b² + ab + a²) / 3 - (b² + 2ab + a²) / 4

Var(X) = [(b-a)²]/12

This is our variance (Var(X)).

Standard deviation: σ(X) = √Var(X)

Substituting the value of variance in the above formula:

σ(X) = √(b-a) / √12

This is our standard deviation (σ(X)).

Step-by-step explanation:

It’s all solve for x what number actually makes the equation true.

The quadratic function that models the distance traveled is: f(t) = 5t² - 5t + 10.

To write a quadratic function that models the distance traveled, we can use the general form of a quadratic function:

f(x) = ax² + bx + c.

Given that the object is increasing its speed at a constant rate, we can assume that the distance traveled is a quadratic function of time.

Let's start by substituting the given values into the quadratic function.

When t = 1 sec, the distance traveled is 10 ft.

So, f(1) = a(1)² + b(1) + c = 10.

When t = 2 sec, the distance traveled is 30 ft.

So, f(2) = a(2)² + b(2) + c = 30.

When t = 4 sec, the distance traveled is 100 ft.

So, f(4) = a(4)² + b(4) + c = 100.

We now have a system of three equations:
a + b + c = 10   (Equation 1)
4a + 2b + c = 30   (Equation 2)
16a + 4b + c = 100   (Equation 3)

We can solve this system of equations to find the values of a, b, and c.

By solving this system, we find that a = 5, b = -5, and c = 10.

Therefore, the quadratic function that models the distance traveled is: f(t) = 5t² - 5t + 10.

Function 1 has a greater slope than Function 2, and the answer is Function 1.

Function 1 is defined by the equation y = \(\frac{5}{4}r - 1\).

Function 2 is defined by line p, which is shown on the graph.

The problem asks which function has a greater slope.

The slope of a line is calculated by the ratio of the difference between the vertical axis values and the difference between the horizontal axis values.

This is shown in the formula:

slope = rise/run.

Here, rise refers to the vertical difference and run refers to the horizontal difference.

This means that the slope of a line measures how steeply the line is increasing or decreasing.

Function 1: y = \(\frac{5}{4}r - 1\)

Here, the equation of Function 1 is given as y = \(\frac{5}{4}\)r - 1.

From this equation, we can see that the slope of Function 1 is equal to \(\frac{5}{4}\).

Therefore, the slope of Function 1 is 1.25.Function 2: Line pNext, we need to determine the slope of line p, which represents Function 2.

To do this, we can use two points on the line.

From the graph, we can see that the line passes through the point (0, -2) and the point (4, 1).

The rise of this line is equal to 1 - (-2) = 3, while the run is equal to 4 - 0 = 4.

Thus, the slope of line p is equal to 3/4.

Therefore, the slope of Function 2 is 0.75.

Comparing the slopes, we can see that Function 1 has a greater slope than Function 2.

Specifically, the slope of Function 1 is 1.25, while the slope of Function 2 is 0.75.

Answer:

Step-by-step explanation:lllllLet's start by using "R" to represent the number of apps that Rita started with, and "C" to represent the number of apps that Cora started with.

We know that Rita deleted 5 apps, so she would have (R-5) apps remaining. And we know that she still had twice the amount of Cora, which is 36.

So we can write the equation:

R-5 = 2C

And we also know that Cora had 36 apps, so we can substitute that value in for C:

R-5 = 2(36)

Simplifying the right side:

R-5 = 72

Finally, we can solve for R by adding 5 to both sides:

R = 77

So Rita started with 77 apps, and Cora started with 36 apps. We can check that Rita deleted 5 and had twice as many as Cora by plugging our values into the original equation:

77 - 5 = 72

2(36) = 72

Both sides are equal, so our solution is correct.
