A) Use the rationalized expression from part a. to calculate the time in seconds that a cliff diver is in free fall. Assume the acceleration due to gravity, a, is –9.81 m/s and the dive distance, d, is –35 m. The negative numbers indicate the direction is downward. Round the answer to two decimal places. Use the formula to calculate the velocity of the diver in km/h when she or he hits the water. Round the answer to one decimal place.

answer: 20

step-by-step explanation:

3; 9 is 8 to -4

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

factor trees are nice.
