A) to get the profit to equal to 0
-x^2+6x+432=0
divide all by -1 to get rid of the negative in front
x^2-6x-432=0
factor
(x-24)(x+18)=0
x=21,-18
can’t sell -18 items so the answer is
24 ITEMS

b)maximize the profits meaning the maximum points aka. the VERTEX (where the graph is at its highest)
using x=-b/2a formula
you get x=3
to maximize the profit, they need to sell 3 items

What is the area, in square feet, of the trapezoid below?
slavikrds [6]

Answer:

68.75

Step-by-step explanation:

Measure the length of the parallel sides and add them together. Then multiply this number by the height of the area. Then multiply by ½ or divide by two to find the square footage of the trapezoid.  

13.6 + 5.9= 19.5

19.5 + 8 = 27.5

27.5 x 5 = 137.5

137.5 x 1/2 = 68.75

a flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 30 feet mor
yarga [219]
Turn phrases into mathmatical expressions:

"<span>one side(s) twice the length of the shortest side(x)" = 2x
"</span><span>the third side(t) is 30 feet more than the length of the shortest side " = x+30
</span>Shortest side= x

Perimeter= side1+ side 2 + side 3
138ft= x+2x+x+30
138= 4x+30
108=4x
x= 27 feet

Answer: 
The shortest side is 27ft. The middle side 2x= 2(27)= 54ft. The longest side being x+30= 27+30= 57ft.

Quick problem to check!
Andrew [12]

To find the rate of change, also known as the slope, we can use the slope formula with these two given points.

Point 1: (20, 25)

Point 2: (50, 40)

(40 - 25) / (50 - 20)

15 / 30

0.5

The rate of change of this function is $0.50 / lb.

Hope this helps!! :)

Is g(x)=4+x^2/1+x^4 even, odd or neither
UkoKoshka [18]

Since g(-x) is equal to g(x), the function is an EVEN FUNCTION.

<h3>Is the given function even, odd or neither?</h3>

Given the function in the question;

g(x) = (4 + x²)/(1 + x⁴)

To determine if the function is even, odd or neither, we find g(-x) by substituting -x for all occurrence of x in the function.

g(x) = (4 + x²)/(1 + x⁴)

g(-1) = (4 + (-x)²)/(1 + (-x)⁴)

Simplify

g(-x) = (4 + x²)/(1 + x⁴)

Hence,

g(-x) = g(x)

Since g(-x) is equal to g(x), the function is an EVEN FUNCTION.
