PZ HELP I HAVE A DEADLINE Two elevators begin descending from the same height. Elevator A has descended 4 feet after one second, 9 feet after two seconds, 14 feet after three seconds, and so on. Elevator B has descended
3.5 feet after one second, 6.5 feet after two seconds, 9.5 feet after three seconds, and so on.
How many feet would each elevator descend in 10 seconds?

A: 59 ft; B: 36.5 ft

A: 49 ft; B: 30.5 ft

A: 85 ft; B: 72 ft

A: 54 ft; B: 33.5 ft

Which shows one way to determine the factors of 4x3 + x2 – 8x – 2 by grouping?

The table below shows the approximate height of an object x seconds after the object was dropped. the function h(x)= -16x^2 +100 models the data in the table. for which value of x would this model make it the least sense to use? a. -2.75 b. 0.25 c. 1.75 d. 2.25
