The answer is 157kJ
formula: q=mcT
q= 75 g x 4.18 J/goC x 50 oC
q= 157 kJ

It shouldn’t be any longer vertically so that should be your answer
A = 4.25p
this equation says that the amount that you spent (A) is equal to the how many pounds of cherries you buy (p) and you know from the question that each pound costs 4.25

Therefore, find f(2) and g(2) first before subtracting.

Therefore,

Then find g(2)

Then put f(2) to subtract g(2)

Therefore, the answer is (f-g)(2) = -49.
