Easy algebra question below first correct answer gets brainliest

Mathematics
1 answer:
Alexxx [7]3 years ago
7 0

Answer:

3

Step-by-step explanation:

Easy pythagorean theorum question.

The law states that "A squared plus B squared, equals C squared."

A and B are the two sides that border the 90 degree mark.

C is the hypotenuse or the longest side/diagonal.

Since we know C and A (I chose to use A because why not) we can fill in the equation with what we know

2^2 + ?^2 = \sqrt{13^{2} }

So

4 + ?^2 = \sqrt{13^{2} }

Since the 13 is already squared in side of a root, it stays as 13

4 + x^2 = 13

4 - 4 + x^2 = 13 - 4

x^2 = 9

x^2 root = root of 9

x = 3

The missing side is 3.

Or you could use an online calculator xD

You borrowed $11,250 from the bank to buy a used car. You will pay the bank back in 5 years with 3.45% interest compounded annua
mihalych1998 [28]

Answer:

(D)$2079.23

Step-by-step explanation:

If I borrowed $11,250 from the bank to buy a used car. You will pay the bank back in 5 years with 3.45% interest compounded annually, then:

Principal=$11,250

Time=5 years

Rate=3.45%

Since it is compounded annually, our compound interest will be derived using this formula:

Interest=Amount at the end of 5 years - Principal

where:

Amount, A=P(1+r)^n

=11250(1+0.0345)^5\\=11250(1.0345)^5\\=13329.23

Therefore our Interest=13329.23-11250 =$2079.23
