Answer: 10 inches per year.

If the snake is now 3 foot 9 inches, we can add up how many inches that is by converting feet to inches. 1 foot=12 inches, so 3 feet is 36 inches. We then add the 9 inches.

36+9= 45

Since the snake had already accomplished being 5 inches at birth, we can subtract 5 from 45.

This gives us 40.

Since the snake was born 4 years ago we divide 40 by 4.

40÷4= 10

Answer:

73.21% annual percentage rate.

Step-by-step explanation:

3 foot 9 inches = 45 inches

45 = 5(1 + r)4

9 = (1 + r)4

91/4 = 1 + r

r = 0.73205

therefore,

r = 73.21%

The compound interest will be equal to $13.57.

<h3>What is compound interest?</h3>

The interest on a loan or deposit that accrues on both the initial principal and the accumulated interest from prior periods is known as compound interest.

The compound interest will be calculated by:-

CI = P(1+\dfrac{r}{12})^{12t}-P

CI = 250(1+\dfrac{0.053}{12})^{12}-250

CI = $13.57

Therefore the compound interest will be equal to $13.57.

A student performed the following steps to find the solution to the equation x^2 + 14x + 40 = 0. Where did the student go wrong?
Alja [10]

Answer:

A. in Step 3

Step-by-step explanation:

It is factored correctly. Then separated into two smaller equations correctly. But in solving x + 10 = 0, there is an error.

x + 10 = 0

Add -10 to both sides.

x = -10

So, the error is in step 3.
