level.

DaniilM [7]2 years ago

Answer:

14.2 feet

Step-by-step explanation:

I'm guessing the question is asking how far did Joey travel from the diving board.

Joey is 5.6 feet above 0 so to reach 0 we must subtract 5.6

-5.6 + - 8.6 = - 14.2 feet

Joey traveled 14.2 feet

Sam borrows $5700 at 4.5% simple interest for 3 years. Find the interest
kherson [118]

Answer:

The interest is

<h2>$ 769.50</h2>

Step-by-step explanation:

Simple interest is given by

I =   \frac{P \times  R  \times T}{100}

where

P is the principal

R is the rate

T is the time given

From the question

The principal / P = $ 5700

The rate / R = 4.5%

The time given / T = 3 years

So the interest is

I  =  \frac{5700  \times 4.5 \times 3}{100}

I =  \frac{76950}{100}

We have the final answer as

I = $ 769.50

Hope this helps you

Which of the following is not a function?
rusak2 [61]
Answer: B

Number on the left: x-value
Number on the right: y-value

If there are 2 y-values for one x-value it is NOT considered a function.

For instance in the answer:

(2,3), (2,4), (3,3), (3,4)

You can clearly see that the x-values (2 & 3) repeat more than once; therefore, it is NOT a function.

On the other hand if you have 2 DIFFERENT x-values for the same y-value it IS A FUNCTION.

For ex D: (2,4), (3,4), (5,4), (6,4)

As you can see there are 4 DIFFERENT x-values with same y-value; therefore it is A FUNCTION

To make it easier:

If x-values appear more than once = NOT A FUNCTION

If x-values appear only ONCE = FUNCTION

Remember: y-values are ALLOWED to repeat

I hope this helps. If you have any questions please let me know in the comments.

x2 + 8x + 6 (x2 + 8x + ) + 6 Erin was completing the square of the quadratic function in order to find the extreme value. What i
kolezko [41]

Answer:

C.

Step-by-step explanation:

The next step is to add (1/2 * 8)^2 = 4^2 = 16 to the 8x and subtract 16 from the + 6:

- to give (x^2 + 8x + 16) + 6 - 16 as the next step in the process.

The extreme minimum is  +6 - 16 = -10.
