Find the maximum/minimum value of the function. h(x)=-4x^2-4x+24

Find The Maximum/minimum Value Of The Function. H(x)=-4x^2-4x+24

Answers

Answer 1

Answer:

The maximum value of h is -1/2

Step-by-step explanation:

Since a is negative, the parabola opens downwards. Therefore, we look for the maximum value of h. We can find this by finding the x-coordinate of the vertex which is x=-b/2a=-(-4)/2(-4)=4/-8=-1/2

Therefore, the maximum value of h is -1/2

Is the figure a polygon? Is it convex or concave? ​

Answers

Answer:

This figure is not polygon and it is a concave

Step-by-step explanation:

A regular polygon has equal length sides with equal angles between each side. Any other polygon is an irregular polygon, which by definition has unequal length sides and unequal angles between sides. Circles and shapes that include curves are not polygons - a polygon, by definition, is made up of straight lines.

And a convex is like a circle. But a concave having an outline or surface that curves inward like the interior of a circle or sphere.

x = 45

Step-by-step explanation:

The angles are supplementary

(2x + 40) + (3x - 85) = 180

Combine like terms

5x - 45 = 180

Add 45 to both sides

5x = 225

Divide both sides by 5

x = 45
