Answer: Complex
Step-by-step explanation:
Answer: 225km
Step-by-step explanation:
3cm --- 150
1cm ---- 50
Therefore 4.5cm * 50 = 225km
If you are implying that the triangles are similar, then the short and long legs are in proportion:

Solving for x, you have

A function assigns the values. The force that will be required to move the rock is 48 lbs.
<h3>What is a Function?</h3>
A function assigns the value of each element of one set to the other specific element of another set.
A.) The inverse of the function f(x)=1/x is,
f(x) = 1/x
y = 1/x
x = 1/y
g(x)=1/x
Hence, The inverse of the function f(x)=1/x is g(x)=1/x.
B.) The force that will be required to move the rock using the momentum,
9ft × 80lbs = 15 ft × F
F = 48 lbs
Hence, The force that will be required to move the rock is 48 lbs.
