Answer:
Below.
Step-by-step explanation:
a. 5 * 1000 = 5,000 micrometers
b. 5000 / 1000 = 5 kg
c. 4.23 * 10^12 = 4,230,000,000,000 picograms
d. 1.9 ^ 10^9 = 1,900.000,000 nanoseconds.
e. 2.3 million.
The inverse of the function are respectively; f⁻¹(3) = 2 and f⁻¹(8) = 8.5
<h3>How to find the inverse of a Function?</h3>
The formula to find the equation of this function using two coordinates is;
(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1)
Using the first 2 coordinates, we have;
(y - 1)/(x + 1) = (3 - 1)/(2 + 1)
(y - 1)/(x + 1) = 2/3
3y - 3 = 2x + 2
3y = 2x + 5
y = ¹/₃(2x + 5)
Thus, the inverse is;
f⁻¹(x) = (3x - 5)/2
Thus;
f⁻¹(3) = (3*3 - 5)/2
f⁻¹(3) = 2
Similarly;
f⁻¹(x) = (3x - 5)/2
Thus;
f⁻¹(8) = (3*8 - 5)/2
f⁻¹(8) = 8.5

Answer:
x=20
Step-by-step explanation:
5(x+9) =145 (watch carefully)
5x + 45 = 145
5x + 45 - 45 = 145 - 45
5x = 100
5x/5 (to cancel eachother out) then --> 100/5
x=20
Answer:
4.8x4=19.2, and then 19.2/4=4.8 feet
Each side would be 4.8 feet
