Ahawk flying at a height of 60 feet spots a rabbit on the ground. if the hawk dives at a speed of 55 feet per second, how
long will it take the hawk to reach the rabbit?
(hint: a model for the vertical motion of a projected object is given by the equation h = -16t2 + vt + s, where h is the height
in feet, t is the time in seconds, v is the initial velocity in feet per second, and s is the starting height of the object in feet. use
this equation to find the time taken by the hawk to reach the rabbit.

The hawk reaches the rabbit at t=4.3 sec

Step-by-step explanation:

Let

h ----> is the height in feet

t ----> is the time in seconds

v ---> the initial velocity in feet pr second

s ----- is the starting height

we have

when the hawk reaches the rabbit the value of h is equal to zero

we have

substitute

Solve the quadratic equation by graphing

The solution is t=4.3 sec

see the attached figure

answer: ok

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
