Question

Select all the correct answers.
Wayne and Winston are scuba diving and are ascending to the surface. The function y = 30x − 105 represents Wayne’s elevation in feet in terms of the time in minutes he ascends. The table represents Winston’s elevation in feet in terms of the time in minutes he ascends. Assume that Wayne and Winston both ascend at a constant rate.


Which statements about this situation are true?

Answer 1

Answer:

Wayne: -105 is start

Winston: -100 is start

Step-by-step explanation:

From the above question,

They have given :

The function  represents Wayne's elevation in  in terms of the time in  he ascends.

Here we have to find,

The table represents Winston's elevation in  in terms of the time in  he ascends.

Assume that Wayne and Winston both ascend at a constant rate.

x1 = 0

x2 = 3

y1 = -100

y2 = -16

First find slope or rate of winston(0,-100) and (3,-16)

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

slope=(-16-(-100))/(3-0)=(-16+100)/(3)=84/3=28/1

wane slope or elevation gain

y=mx+b

m=slope or rate of elevaion gain

b=yintercept or starting oint

y=30x-105

slope or rate of change is 30

30 vs 28 wane acends faster than winston

also, the starting point or when x=0 point is the starting point

wayne: -105 is start

winston: -100 is start

wane started deeper

so the true statements are

Wayne ascends at a faster speeds

Wayne was deeper when he began ascending
