Thank you for asking this question! I'd love to help you!

The answer to your question is 57.92 because when you add 30.12 and 27.8, you get the answer of 57.92, and when you estimate it, you get an estimate of 58. <u><em>Estimate/Answer: 58</em></u>

Answer:

C

Step-by-step explanation:

Once

\sqrt{xy} = 6

We know that xy = 36

There are infinity values for x, y, but considering x, y \in \mathbb{Z}

Below we have all the solutions for x, y

Negative:

\\x = -36 \text{ and } y = -1\\x = -18 \text{ and } y = -2\\x = -12 \text{ and }  y = -3\\x = -9 \text{ and }  y = -4\\x = -6 \text{ and }  y = -6\\x = -4 \text{ and }  y = -9\\x = -3 \text{ and }  y = -12\\x = -2 \text{ and }  y = -18\\x = -1 \text{ and }  y = -36\\

Positives:

x = 36 \text{ and } y = 1\\x = 18 \text{ and } y = 2\\x = 12 \text{ and }  y = 3\\x = 9 \text{ and }  y = 4\\x = 6 \text{ and }  y = 6\\x = 4 \text{ and }  y = 9\\x = 3 \text{ and }  y = 12\\x = 2 \text{ and }  y = 18\\x = 1 \text{ and }  y = 36\\

We can see that x + y \neq 18

Please help with the first question....

Answer:

  A)  The functions are not inverses of each other.

Step-by-step explanation:

f(g(x))=\sqrt{(x^2+3)-3}=\sqrt{x^2}=|x|\ne x

The result of f(g(x)) is not always x, so the functions are not inverses of each other.

In general, a quadratic (or any even-degree polynomial) such as g(x) cannot have an inverse function because it does not pass the horizontal line test.

A model plane is 1/48 the size of an actual plane. If the model plane is 28 inches long, how long is the actual plane?
Ratling [72]
You would say 1/48=28/x and solve the proportion to get an answer of 1344 inches, which is 112 feet.
