Another question for math. ill give mad points, the question is in attachment
yulyashka [42]
For this case we have the following points:
 y = (- 2, 5)
 z = (1, 3)
 Therefore, the vector yz is given by:
 yz = z - y = (1, 3) - (-2, 5)
 yz = ((1 - (- 2)), (3-5))
 yz = ((1 + 2), -2)
 yz = (3, -2)
 Then, the magnitude is given by:
 lyzl = root ((3) ^ 2 + (-2) ^ 2)
 lyzl = root (9 + 4)
 lyzl = root (13)
 Answer:
 
yz = (3, -2)
 lyzl = root (13)

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>
