I NEED HELP ASAP PLEASE only BRAINLIST a for correct answers

PROFIT The profit P of a company, in thousands of dollars, can be modeled by P = 12.75 * root(3, c ^ 2) where is the number of customers in hundreds. What is the profit of the company if the company has 3200 customers?

128511.95 is the profit of the company if it has 3200 customers.

Step-by-step explanation:

Does the 3 with the comma mean cube root?

P(c)=12.75*cuberoot(c^2) - if that is what I understand

to find the profit of the company with 3200 customers, we substitute 3200/100 it in for c

P(32)=12.75*cuberoot(32^2)

If you use a calculator.. you will get

around 128.511947

the profits are in thousandsa of dollars so multiply  128.51194 times 1000

which gives you..

around 128511.95

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

i googled it and this is what i got i don't know how it is. sorry.

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
