Answer:
20/48
Step-by-step explanation:
Answer:
500 pounds
Step-by-step explanation:
Let the pressure applied to the leverage bar be represented by p
Let the distance from the object be represented by d.
The pressure applied to a leverage bar varies inversely as the distance from the object.
Written mathematically, we have:

Introducing the constant of proportionality

If 150 pounds is required for a distance of 10 inches from the object

Therefore, the relationship between p and d is:

When d=3 Inches

The pressure applied when the distance is 3 inches is 500 pounds.
Answer:
Option D is correct.
Step-by-step explanation:
f(x)= 9x^2 -12
Let y = 9x^2 - 12
Switch places of x and y and solve for y
x = 9y^2 - 12
Adding 12 on both sides
x + 12 = 9y^2
Dividing both sides by 9
x+12/9 = y^2
=> Taking square root on both sides
=> 
Replace y with g(x)

Option D is correct.
