Tell the kind of symmetry this figure has: point, line, plane. (Select all that apply.)

e-lub [12.9K]

Since a circle is simple it has no points but it can be folded many times so symmetry is really unlimited for the circle.It is not a plane because it is round and does not have sides.

A company sells widgets. The amount of profit y made by the company is related to the selling price of each widgets x by the giv

SCORPION-xisa [38]

Answer:

The maximum amount of profit is 32

Step-by-step explanation:

Given

$y=-x^2+64x-292$

Required

Determine the maximum profit

This is calculated by calculating the maximum of the function.

A quadratic function is of the form

$y = ax^2 + bx + c$

and its maximum is:

$Max = \frac{-b}{2a}$

So: $y=-x^2+64x-292$

We have that

$a = -1$

$b = 64$

$c = -292$

$Max = \frac{-b}{2a}$

$Max = \frac{-64}{2 * -1}$

$Max = \frac{-64}{-2}$

$Max = 32$

<em>Hence, the maximum amount of profit is 32</em>
