The distance between 2 points

and

on the coordinate plane is

So the distance between the given points is

As every unit is 1 mile, so the distance should be 10.8*1=10.8miles.
Hope this helps.
a) 70.1 m
The ball is moving by uniformly accelerated motion, with constant acceleration
(acceleration due to gravity) towards the ground. The height of the ball at time t is given by the equation

where
is the height of the ball at time t=0. Substituting t=1 s, we can find the height of the ball 1 seconds after it has been dropped:

b) 3.9 s
We can still use the same equation we used in the previous part of the problem:

This time, we want to find the time t at which the ball hits the ground, which means the time t at which h(t)=0. So we have

And solving for t we find

Answer:
D.
Step-by-step explanation:
It would be best to first make sure the line follows the direction of the dots; immediately eliminating B & C.
Then you want to make sure that the estimated line is in the middle and near all of the dots in some way; leaving the final answer, D.
Answer:
there are four significant figures
Step-by-step explanation:
zeros to the right of a non zero digit are ambiguous
Wouldn’t you just subtract 2 from 2?
