A force of 3 pounds acts in the direction of 42 degrees to the horizontal. The force moves an object along a straight line from the point (3,7) to the point (8,8), with distance measured in feet. Find the work done by the force in foot-pounds.

11.37 lb-ft

Step-by-step explanation:

We are given that

Force,F=3 pounds

Let Point  A (3,7)  and point B(8,8)

We have to find the work done by the force.

feet

We know that Work done by the force

Substitute the values

Hence, the work done by the force =11.37 lb-ft

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

8y^50
