Answer

The length of the hypotenuse is 35 feet.

Explanation

This is the formula to find the hypotenuse.

$l^{2} + l^{2} = h^{2}$

One leg is 21 feet. The other is 28 feet. Now insert those into the formula.

$21^{2} + 28^{2} = h^{2}$

$h^{2}=1225$

Now to find what h is you should find the square root of 1225.

$\sqrt{1225} =35$

So the length of the hypotenuse is 35 feet.

True or false and if false what would be the correct term be?

vagabundo [1.1K]

It’s True.. you take the “extreme” variable from each proportion and cross multiply them before setting them equal to the product of the two “means” (which are just the other 2 numbers in the proportions).

Step-by-step explanation:

r = 10% = 0.10

$v(t) = P (1 - r)^t\\\\V(t) = 12000(1 - 0.10)^t\\\\V(t) = 12000\times (0.9)^t$
