When an exponent is a fraction, the denominator is written as a root, while the numerator is the power:

Since a is to the power of 5/7, the 7 becomes the 7th root, and the 5 becomes a^5. This is:

Angela enjoys swimming and often swims at a steady pace to burn calories. At this pace, Angela can swim 1,700 meters in 40 minut
KATRIN_1 [288]
Well, if you are talking how much she can swim per minute, you have to divide 1700 by 40 to get the unit per minute, 1700 being the meters she can swim, and 40 are the minutes she takes to swim. So, 1700 divided by 40 would be 42.5 meters per minute. So Angela's unit is 42.5 meters per minute. YOU'RE WELCOME :D

Par a:- 7150 rands

Part b:- about $878.

If f(x) = 2x+1/x-4 what is the value of f^-1(3)
Olegator [25]

Answer:

f^-1(3) = 1.719 or  f^-1(3) = 0.149

Step-by-step explanation:

for inverse function x and y coordinates are flipping so graph the function and find for what x - coordinate y- coordinate = 3

in case that f(x) = 2x + \frac{1}{x-4} than f^-1(3) = 1.719

in case that f(x) = 2x + \frac{1}{x} -4 than f^-1(3) = 0.149
