tina is going for a bike ride. when she leaves her house, she starts pedaling and her speed steadily increases. as she approaches the stop sign at the end of her street, she slows down at a steady pace until she comes to a complete stop. after waiting at the stop sign for her turn to go, she starts pedaling again and her speed steadily increases at a slower pace than when she first left her house. she reaches a comfortable speed and rides at this speed until she approaches another stop sign, causing her to steadily slow down until she again comes to a complete stop.

which graph represents tina’s bike ride?

Step-by-step explanation:

Alright, lets get started.

There are 6 different stages of Tina's bike ride.

First: When she starts, her speed continuous increases means graph goes up.

Second : After seeing the stop sign, she slows down and speed reached to zero.

Third : She waits at stop sign, so, there is zero speed for some time.

Fourth : She again starts but at lower speed than previous speed.

Fifth : She makes a ride with steady speed.

Sixth : She finally slow down her speed and ends to zero.

So, the answer is second graph.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
