Answer:
100 miles
Step-by-step explanation:
Remark
All you need do is start at 4 hours on the y axis and go right until you hit a dot. When you do, go down until you hit a number on the x axis.
It helps if you mark up the graph.
Go right from 4
You hit a dot
Look down.
You should see 100. That's how far you go in 4 hours.
Note
This is an odd graph. Usually time is on the x axis.
Answer:
y ≈ 4.3 cm
Step-by-step explanation:
Given 2 secants from an external point to the circle.
The the product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
3(3 + y) = 2(2 + 6 + 3) = 2(11) = 22, that is
9 + 3y = 22 ( subtract 9 from both parts )
3y = 13 ( divide both sides by 3 )
y ≈ 4. 3 cm ( to the nearest tenth )
