Answer:
252
Step-by-step explanation:
if you go around the faces, 20*5 is 100, 20*4 is 80, 20*3 is 60, 2*3 is 6 and another 2*3 is 6. add these together
Complementary is when angles equal 90 degrees.
supplementary is when angles equal 180 degrees.
a)

Answer:
420 miles in 2 hours.
If it where to fly for 13 hours then you divide 420 by 2 which is 210. Multiply 210 by 13.
=2730 miles.
The rate of speed would be 420 divided by 2. This would equal 210 miles per hour.
"Inverse of an exponent?" Unsure of what you mean. Do you want to find the inverse of an exponential function?
Suppose y = 2e^x. Find the inverse function:
1. Interchange x and y: x = 2e^y
2. Solve this for y: ln x = ln 2 + y, so y = ln x - ln 2, or y = ln (x/2) (answer)
