Answer:

polygon has 12 sides

Step-by-step explanation:

the sum of the exterior angles of a polygon is 360°

the sum of the interior angles of a polygon is

sum = 180° (n - 2 ) ← n is the number of sides

given the sum of the interior angles is 5 times sum of exterior angles, then

sum = 5 × 360° = 1800° then

180° (n - 2) = 1800 ( divide both sides by 180 )

n - 2 = 10 ( add 2 to both sides )

n = 12

Thus the polygon has 12 sides

Answer:

12 sides

Step-by-step explanation:

the sum of the exterior angles of a polygon is 360°

since the polygon is regular then the exterior angles are congruent

number of sides = 360° ÷ 30 = 12

Answer:

Step-by-step explanation:

Answer:

The range is 12, 0, -6

Explanation:

Given the function:

f(x) = 4 - 2x

We want to find the range of this function, given that the domain is:

-4, 0, 5

This can be done by replacing x by each element ot the domain in the given function, find f(x).

For element -4

f(-4) = 4 - 2(-4)

= 4 + 8

= 12

For element 0

f(0) = 4 - 2(0)

= 4 - 0

= 0

For element 5

f(5) = 4 - 2(5)

= 4 - 10

= -6

The range is 12, 0, -6

Answer:

The diver's position in feet (depth) when she swims with dolphins is -83 feet.

Step-by-step explanation:

First highlight the important information from the question.

A diver sits on a boat at the surface of the ocean preparing to dive. She dives in and descends to -128 feet. After a few minutes, she ascends 45 feet to swim with a pod of dolphins that has appeared. What integer represents the diver's position in feet (depth) when she swims with the dolphins?

So, first she descends -128 feet, then she ascends 45 feet to swim with dolphins. So, now that we have the important information highlighted we can solve the problem.

-128+45=-83.

The diver's position in feet (depth) when she swims with dolphins is -83 feet.

Hope this helps!

Answer:

No solution

Step-by-step explanation:

Data provided in the question related to inequalities are as follows

\(y>\frac{3}{2}x-1\\\\)

\(y<\frac{3}{2}x-1\)

Now the related equation for both inequalities is

\(y=\frac{3}{2}x-1\)

When x=0,

\(y=\frac{3}{2}(0)-1=-1\)

When x = 2,

\(y=\frac{3}{2}(2)-1=2\)

This represents that the both lines are passed through(0,-1) and (2,2).

In indicates both line passes through (0,-1) and (2,2). Everything is colored to the right of the first line and everything is colored to the left of the line. It implies there is no feasible region to the inequalities.

Step-by-step explanation:

The correct answer is (d) The price must be replaced with a relative price, and the marginal values must be replaced with the corresponding Marginal Rates of Substitution.

When the value of a public good cannot be expressed in monetary terms, the Samuelson condition still holds, but some modifications are required. In this case, the per-unit price (p) used in the Samuelson condition needs to be replaced with a relative price, which represents the trade-off between the public good and other goods or services. Additionally, the marginal values (MV) of the public good need to be replaced with the Marginal Rates of Substitution (MRS), which measure the rate at which one person is willing to substitute the public good for another good.

Therefore, to determine the efficient level of the public good, the modified Samuelson condition uses a relative price and the corresponding Marginal Rates of Substitution.

As a car dealer lowers a vehicle that was worth 18300 to 16000 by applying the formula of change in percentage we get that by 12.569 percentage (approximately) the price gets lowered .

The initial price of the car is set at P = 18300 (units)

The price after lowering drom P becomes A= 16000 (units)

Hence the change in price (or value) of the car, that is the price of the car is lowered by, C = (initial price - lowered price) = (P - A) = (18300 - 16000) units = 2300 units.

The formula for calculating percentage change is given as follows,

Change in percentage = [(Change in value)/ ( Initial value) ]*100

⇒Change in percentage = (C/ P)*100

⇒ Change in percentage =( 2300/ 18300)*100 = 12.569% (approximately)

the radius of the larger circle is $\sqrt{3} - 1$.

The radius of the larger circle can be determined by considering the centers of the smaller circles and the points of tangency. Let's denote the radius of the larger circle as R.

Since the three smaller circles are externally tangent to each other, the centers of the smaller circles form an equilateral triangle with side length equal to the sum of their radii, which is $2 + 2 + 2 = 6$. The larger circle is tangent to the sides of this equilateral triangle.

To find the radius of the larger circle, we can draw an altitude from the center of the larger circle to one of the sides of the equilateral triangle. This altitude splits the equilateral triangle into two congruent 30-60-90 triangles. The altitude is equal to the radius of the larger circle plus the radius of one of the smaller circles, which is $R + 1$.

In a 30-60-90 triangle, the length of the hypotenuse (R + 1) is twice the length of the shorter leg (1). Therefore, we have:

$2 = (R + 1) \cdot \frac{1}{\sqrt{3}}$

Solving for R, we get:

$R = \sqrt{3} - 1$

The Euler's timestepping method is implemented in the MATLAB function euler_timestep to solve the initial value problem (IVP) dy/dt = f(t,y), a≤t≤b, y(0)=α.

The function takes as input the function f, the interval [a,b], the initial value α, and the number of intervals N. It returns an array y that contains the solution evaluated at all time steps.

To solve the specific IVP dy/dt = (sin(2t) - 2ty)/t², y(1)=2 on the interval [1,5] with N = 10, 10², 10³, we can call the euler_timestep function three times with different values of N. Let's denote the solutions as y0, y1, and y2. We can then plot the three solutions with respect to t.

To compute the exact solution, we can use the MATLAB function dsolve to obtain the symbolic expression. However, since Cody coursework might not recognize dsolve, we need to compute the exact solution on MATLAB and copy the expression to Cody.

Finally, we can make a log-log plot of the absolute error at t = 5 versus the number of intervals for all three methods on the same plot. This allows us to compare the accuracy of the different methods.

In terms of the results, we can analyze which method works best and which works the worst by examining the accuracy of the solutions and the error plots. The accuracy can be evaluated by comparing the exact solution with the numerical solutions obtained using different values of N. The error plot will show how the error changes as the number of intervals increases for each method. Based on these observations, we can draw conclusions about the performance and effectiveness of each method in solving the given IVP.

The minimum value of the function f(x) = r - 27 on the interval (0,8) is -27, and the maximum value is r - 27.

Given the function f(x) = r - 27, where r is a constant, we need to find the minimum and maximum values of f(x) on the interval (0,8).

In the given function, the term r is a constant, meaning it does not depend on the variable x. Therefore, the value of r remains the same throughout the interval (0,8).

On the interval (0,8), the minimum value of the function occurs when the variable x is at its minimum value, which is 0. Substituting x = 0 into the function, we get f(0) = r - 27. This gives us the minimum value of -27, regardless of the value of r.

Similarly, the maximum value of the function occurs when the variable x is at its maximum value, which is 8. Substituting x = 8 into the function, we get f(8) = r - 27. Since the value of r is constant, the maximum value of f(x) is r - 27.

Therefore, on the interval (0,8), the minimum value of the function f(x) = r - 27 is -27, and the maximum value is r - 27. The exact value of the maximum depends on the specific value of r.

To sketch the graph we have to solve the function with each value of x to get the coordinates.

f(x) = x² − 4x − 5

−2 ≤ x ≤ 6

This inequality represents the domain for x. Therefore x is greater than equal to -2 but less than equal to 6.

The range of x is as follows:

x = -2, -1, 0, 1, 2, 3, 4, 5, 6

We already have the values for x therefore, we must substitute the values of x into the function f(x) = x² − 4x − 5 to find the y values.

For x = 5

f(x) = x² − 4x − 5
