A parachutist's speed during a free fall reaches 70 meters per second. What is this speed in feet per second? At this speed, how many feet will the parachutist fall during 20 seconds of free fall? In your computations, assume that 1meter is equal to 3.3 feet

Speed is 231 ft/s.

Distance is 4620 ft.

Solution:

First we have to convert the unit of speed from m/s to ft/ s.

Then for 20 seconds, we have to calculate the feet covered by the parachute.

In 20 seconds, the parachute covers the distance of,

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

if i put something wrong your not gonna like it so rather not say nothing.
