Find the sum of interior angles of a 10-sided figure. Explain what formula you used to get the answer.

Mathematics

Vilka [71]3 years ago

Answer: 1440°

Step-by-step explanation:

To solve the above question, we'll use the formula (n-2) × 180. In this question, we are told that it has 10 sides. This implies that n= 10. Therefore, using the formula goes thus:

= (n - 2) × 180

where, n = 10

= (10 - 2) × 180

= 8 × 180

= 1440

Given the function f(x)=x^4+8x^3+18x^2+7 determine the absolute minimum value of f on the closed interval [-4, 1].
Blababa [14]

Answer: 7

Step-by-step explanation:

To find the absolute minimum we must first take the derivative of the function and find where it equals zero. From there we can use the first derivative test to find where our possible minimum is. We then will test each endpoint and compare for the minimum for this function.

f(x)=x^4+8x^3+18x^2+7\\f'(x) = 4x^3+24x^2+36x\\\\4x^3+24x^2+36x = 4x(x^2+6x +8)\\\\x = 0\\x = -4\\x = -2\\\\f(-4) =  39\\f(-2) =31\\f(0) = 7\\f(1) = 34

The lowest value is 7. The absolute minimum of this function is 7. If you were to graph it, we'd see that the graph reflects that as well.

What is the solution to the system of linear equations graphed below?
OlgaM077 [116]

Option C: There are no solutions

Explanation:

The linear equations is graphed.

We need to determine the solution of the system of equations.

The solution of the equations can be determined by finding the point of intersection of the two equations.

From the figure, it is obvious that the two equations are parallel to each other.

Also, the parallel lines have the same slope and the parallel lines never intersect.

Hence, the system consisting of parallel lines have no solution.

Therefore, the solution to the system of linear equations graphed is no solution.

Thus, Option C is the correct answer.
