The circumference is πd, and the diameter is 10, so the circumference is 10π. All sides of a square are equal, so the length of each side is 10π/4, which is 2.5π.
The length of each side of the square is 2.5π
No, they forgot to switch variable labels after solving for the independent variable...
y=-8x+4
y-4=-8x
(y-4)/-8=x
Now that you have solved for the independent variable x, you switch the variable labels...
y=(x-4)/-8
f^-1(x)=(x-4)/-8 which should really be rewritten as:
f^-1(x)=(4-x)/8 :P
Answer:
13lbs
Step-by-step explanation:
x = number of pounds of chocolate/lbs
13.20(x) + 3.90(10) = 9.16(x + 10)
13.2x + 39 = 9.16x + 91.6 (x100)
1320x + 3900 = 916x + 9160
404x = 5260
x = 1315/101 = 13.0198.... ⇒ 13lbs
Area of a square:
A= side^2
= (6x + 1) ^2
=<u> 36x^2 + 12x + 1 feet^2</u>
