Rui is a professional deep water free diver. His altitude (in meters relative to sea level), 2 seconds after diving, is modeled by:
1
d(2) =
10.
What is the lowest altitude Rui will reach?
meters relative to sea level

Afootball is throw by a quarterback to a receiver

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

Plz hurry evaluate the expression a+b where a=8 and b=19
