Answer:

Hey there!

The trick to finding the value that completes the square, is dividing the middle number, the 10, by 2, and squaring that. Thus, we have 10/2=5, and 5^2=25.

c=25

Hope this helps :)

Identify the domain and range for the table from problem #5 of your assignment. Also, determine if it represents a function.

Lana71 [14]

Answer:

Domain: {4,5,7,10}

Range: {2,4,8}

Not a function

Step-by-step explanation:

The domain is all the x-values.

The range is all the y-values.

However, this isn't a function because two different inputs have the same output. If it were a function, there would be one unique output for every input.

PLEASE HELP ME ASAP!!! The diagonal of Andres rectangular TV screen is 39 in. The width of his TV screen is 34 inches. which mea

Y_Kistochka [10]

You can use the Pythagorean theorem to answer this. The diagonal is the hypotenuse of the right triangle that is formed. So, your equation will look like (h is height):
$34^2+h^2 = 39^2$

We have to solve for h:
$h^2 = 39^2-34^2$
$h = \sqrt{39^2-34^2}$

You can plug it into a calculator, and you get approximately 19.105. The answer closest to that is B. So, that's your answer! Hope it helps. If anything doesn't make sense, hmu!
