1. If you are driving and spot an object down the road, the distance it will take stop is determined by the sum of these two functions:
Reaction Time: R(S) = 2.2s
Braking time: B(s) = 0.06392
where s is the driving speed.
a. Find the equation of the new function, D(8) that describes the distance it will
take you to stop.
b. If you see a deer in the road and are going 60mph, what is the distance it will
take you to stop before hitting the deer? Explain your answer in context of
the problem.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

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

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
