The force f needed to stop a car varies directly as its weight w and the square root of velocity v are inversely as the distance d travelled. when f=36 newtons, w=120kg, v=100km/h and d=50km. calculate the force required for v=256km/h, w=200kg and d =800km. this is the question pls answer it dont by pass it pls

What is the average rate of change for this function for the interval from x=2 to x=4 ?

Which of the following pairs of functions are inverses of each other? o a. f(x)=x72+8 and 96-9 = 7/x+2) =8 o b. f(x)= 6(x - 2)+3 and g(x) - *#2-3 o c. $4) = 5(2)-3 and 90- 4*: 73 o d. f(x) = 6)-12 and 910 – +12

Saline iv fluid bags cost $64.20 for 24, 1000 ml bags from one supplier. a new supplier sells 500 ml bags for $2 each. the hospital uses about 10,000, 1000 ml bags each month. nurses report that about half of the bags are more than half full when they are discarded. if you are going to use only one supplier, which size bag provides the best deal, and how much will you save each month? compare the cost of the new supplier to the current one.
