B<br> 8<br> 7<br> Find the length of "e" to the<br> nearest tenth using the<br> Pythagorean Theorem.
Juliette [100K]

Answer:

≈ 10.63

Step-by-step explanation:

Pythagorean Theorem... Possibly the most easy theory in math once you understood it.

Here's the formula.

A^2+B^2=C^2

AB would be the hypothenuse

BC would be the opposite

CA would be the Adjacent.

But let's not make it complicated though, the question is actually quite easy.

You are asked to find AB, the hypothenuse.

The hypothenuse would be C.

BC and CA would be A and B.

It doesn't matter where are you going to place the numbers.

So, 7^2 + 8^2

7^2 + 8^2 = 49 + 64\\

= 113

Now we would have to square root 113 since A^2+B^2=C^2

\sqrt{113} is an irrational number, and the question asks you to round ro the nearest tenth.

\sqrt{113} =10.63014581

≈ 10.63

Your answer would be 10.63

Jim has 8 unread emails in his inbox before going on vacation. While on vacation, Jim does not read email. If he receives an ave
Alecsey [184]

Answer:

E_n = 8 + 22n

Step-by-step explanation:

Since emails arrive at a constant rate of 22 per day, the equation for n-th term can be modeled by a linear relationship of general form:

E_n = E_0 + k*t

In this case, E₀ is the initial number of emails unread, 8, k is the rate at which emails arrive, 22 per day, and t is the number of days passed.

At t=n, the number of unread emails is:

E_n = 8 + 22n

If 5x + 32 =4-2x, what is the value of x ?
Ket [755]
Hi there!

To solve this problem, we need to simplify.

5x + 32 = 4 - 2x
7x + 32 = 4
7x = -28

x = -4

Hope this helps!
