We have the following equation:
 2 (x-3) ^ 2 + 10 = 82
 We must clear x.
 We pass the constant terms to one side of the equation:
 2 (x-3) ^ 2 = 82 - 10
 2 (x-3) ^ 2 = 72
 (x-3) ^ 2 = 72/2
 (x-3) ^ 2 = 36
 Square root to both members:
 x-3 = +/- root (36)
 x-3 = +/- 6
 The solutions are:
 x1 = 6 + 3 = 9
 x2 = -6 + 3 = -3
 Answer:
 
x1 = 9
 
x2 = -3

Answer:

B . S /2rh =pi

Step-by-step explanation:

S = 2* pi * r*h

We are solving for pi

Divide both sides by 2rh to isolate pi

S/ 2rh = 2 * pi *r* h / 2rh

S /2rh =pi

Can someone explain to me
Papessa [141]
You plug the x value into whichever function it applies to. X represents the number of shirts ordered. So for example, the first question asks the total cost if you order 57 shirts. Look at the piecewise function. If says is x>50 (or equal), you use the equation 14x + 20. 57 is greater than 50 so plug it into the equation. (14)(57) + 20 = 818. You should be able to do the rest now. If you have any more questions, you can ask.
