The number of pretzels that must be sold to maximize the profit is 400.
<h3>What is the number of pretzels to be sold in the quadratic equation?</h3>
The number of pretzels to be sold can be determined by taking the derivative of the quadratic equation.
Given that:
P(x) = -4x^2+3200x-100
P'(x) = -8x + 3200
P''(x) = -8
At the critical point;
P'(x) = 0
Thus;
8x = 3200
x = 3200/8
x = 400
P''(400) = -8
P'' (400) < 0
Therefore, at x = 400, P(x) will be maximum.

Answer:
A) 27 degrees
Step-by-step explanation:
Arc length = fraction of the circle * circumference
Arc length = fraction of the circle * 2 * pi *r
3/4 pi = fraction of the circle * 2 * pi *5
3/4 pi = fraction of the circle *10 pi
Divide each side by 10pi
3/4 pi
-------- = fraction of a circle
10 pi
3/40 = fraction of a circle
A circle is 360 degrees
3/40 = x/360
Multiply by 360
3/40 *360 = x
27 = x
