Game Stop has a deal on NBA 2K20. The deal lets you get the game for 15% off! TODAY ONLY! Sarah has a coupon that allows her to get an additional $15 off! 18. Write a function that you can use to determine The cost of NBA 2K20 if Sarah uses the in- store discount FIRST.

The function that represents the cost of the game as a function of it's original price is f(x) = 0.15*x - 15.

Step-by-step explanation:

In order to write a function we will attribute a variable to the original price in dollars of the game, this will be called "x" and the price paid by Sarah will be "y". So if the in-store discount is used first we have 15%*x or 0.15*x, and we subtract $15 from that value because of her coupon. We have:

y = f(x) = 0.15*x - 15

The function that represents the cost of the game as a function of it's original price is f(x) = 0.15*x - 15.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
