If we let
x as the length of the pen
y as the width of the pen
The area is
xy = 2000
The perimeter is
P = 2(x+y)
From the area
y = 2000/x
Substituting
P = 2(x + 2000/x)
which is the equation used to find the least amount of fencing possible.<span />
Answer:
You need to use sohcahtoa to find your answer.
first you gotta identify what sides of the triangle you have.
You're missing the hypotenuse, and you have the value of the adjacent.
since you have the adjacent and need the hypotenuse, you're going to use cosine to find x
cos(65) = 16/x
x = 37.859
Answer: I'm not really sure.
Step-by-step explanation:
ANSWER IS LAST CHOICE 256/81
You can take the reciprocal of the fraction and drop the negative sign in the exponent. Then:
(-4/3)^4 = (-4)^4 / 3^4 = 256/81
