Rachel is a stunt driver, and she's escaping from a building that is about to explode!
DDD represents Rachel's remaining distance (in meters) after ttt seconds.
D=-38t+220D=−38t+220D, equals, minus, 38, t, plus, 220
How long is the distance Rachel has to drive

Rachel has to drive for 5.789 seconds

Step-by-step explanation:

The equation that represents Rachel's remaining distance is:

When Rachel completely escaped from the explosion, she has no distance to cover.

Hence D=0.

Divide both sides by -38 to get:

Rachel will cover 220m in approximately 6 seconds.

The total distance she has to drive is 220m

understand that i don't know the answers

will someone answer his question

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
