Answer:

F(-9) would be 13/5

Step-by-step explanation:

1.) add -9 into the equation as the subsitute for x

(should look like \frac{3}{5} (-9)+8 )

2.) Solve the equation with basic algebra

What is the length of the hypotenuse of the right triangle if one side is 16in and one is 7in?
Ronch [10]

Answer:

hypotenuse = 17.46

Step-by-step explanation:

The Pythagorean Theorem is a^2+b^2=c^2.

Since we are finding the hypotenuse, we must plug in 16 and 7 since they represent the lengths of both side.

16^2+7^2=c^2

256+49=c^2

305=c^2

which means we have to find the square root of c^2 AND 305, round it to the nearest hundredth, which means that;

c=17.46
