Best ResponseYou've already chosen the best response.0area of a circle is \[\Pi r^2\] so equate \[\Pi r^2=350ft^2\] divide by pi and take the square root

Best ResponseYou've already chosen the best response.0well on my paper it says the equation is sqrt A/pi= r

Best ResponseYou've already chosen the best response.0thats the same thing.\[\sqrt{A/\Pi}=r\] is the same as dividing the area "A" by Pi and then taking the square root. so A=350, divide by Pi, and then take the square root of that answer

Best ResponseYou've already chosen the best response.0than that's what it is. first find the inverse of the function 2x+5. then plug in 1/2 into the inverse function. then we will take f(x)=2x+5 and replace the x with the answer we got for inverse.

Best ResponseYou've already chosen the best response.0so for the inverse we replace y with x. so it'll be changed to x=2y+5. solve for y. y=(5x+5)/2. plug in (1/2) and we get y=5(1/2)/2. plug in this answer into y=2x+5 and we get y=2(5(1/2))/2+5. the 2's cancel and we get 5(1/2)+5. this equals (1/2).
