From 2 hours to 4 hours she traveled 7 miles.

7 miles  / 2 hours = 3.5 miles per hour.

The slope is 3.5 , which is 3.5 miles per hour, which is how fast she is walking.

Calculate the distance between each given pair of points. Round your answer to the nearest tenth, if necessary.
Ksju [112]
The answer is 5 

Here are the steps:

First off, we will be using the distance formula of 
d=\sqrt{(x_ {2}- x_{2}) ^{2}+( y_{2}- y_{1})^2     }

So we have the ordered pairs of (3,1) and (6,5)

Once you plug them into the formula it should look like this: 
d= \sqrt{(6-3)^2+(5-1)^2}

Now we do the math inside the parenthesis and end up with:
d=\sqrt{3^2+4^2}

Then you multiply by the power and simplify to get:
d=\sqrt{25}

And the \sqrt{25}=5

So your answer is 5

The value of a $25,000 car depreciates at a rate of 12% per year. What will the car be worth in 5 years?
Scorpion4ik [409]

The formula for depreciation is:

Value = Starting value x (1 - rate)^time

Using the given values:

Value = 25,000 x (1-0.12)^5

Value = 25,000 x 0.88^5

Value = $13,193.30 (Round the answer as needed)
