Step-by-step explanation:
We can use the Pythagorean theorem to find the length of the diagonal since drawing a diagonal across a rectangle results in two right angle triangles.
Length of diagonal 
(The length of the diagonal can be thought of as the hypotenuse of one of the right angle triangles)
∴ The length of the diagonal is

Keisha ran 2.4 miles more than Jamal.
Keisha ran 8.5 miles, how many miles did Jamal run?
m = the number of miles Jamal ran
2.4 + m = 8.5
[Keisha ran 2.4 more miles than Jamal(m), she ran a total of 8.5 miles]
2.4 + m = 8.5 Subtract 2.4 on both sides
m = 6.1
Jamal ran 6.1 miles (Your answer is the 2nd option)

61 / 3427= 0.01779982. (rounds up to 0.02 if rounded by hundredths)
For this case we have:
Be a function of the form 
Where:
If we want to find f (-2), we substitute 
, then:
Since we have a negative root, the result will be given by complex numbers. By definition:
So:
