Given that work is the vectorial product of displacement and force. Work can be found with the formula W=F·d

The force that does work as the weight is lifted is gravity. The force is weight
Hence
F
=F_{gravity}
= weight
= mass(acceleration due to gravity)
= 32 pounds(9.8 m/s²)
=14.51(9.8) N
= 142.198

With the F= 142.2, d=10 ft = 3.04 m
W=F·d
   = 142.2· 3.04
   = 432.228 J (Joules)

432.228 joules of work was done

velikii [3]

Answer:

h(x) = 57(0.8)^x

Step-by-step explanation:

Given

f(x) = 32(0.8)^x

g(x) = 25(0.8)^x

Required

A function that represents the total resale value of the two vehicles

To do this, we simply add up the functions

h(x) = f(x) + g(x)

h(x) = 32(0.8)^x + 25(0.8)^x

Factorize

h(x) = (32 + 25)(0.8)^x

h(x) = 57(0.8)^x
