I’m timed plsss answer correctly I’ll mark u brainliest

Artemon [7]

Answer:

$\sqrt{125}$

Step-by-step explanation:

Use Pythagorean theorem since you have a right triangle $15^{2}$ = $10^{2} + x^{2}$

225 = 100 + $x^{2}$ so x = $\sqrt{125}$

The nth term of a sequence is 3n^2- 1

Thepotemich [5.8K]

Answer: The number that belongs to both sequences is 26.

Step-by-step explanation:

We have two sequences, let's call one as A and the other as B.

The n-th term of sequence A is written as:

aₙ = 3*n^2 - 1

the nth term of sequence B is written as:

bₙ = 30 - n^2

We want to find a term that belongs to both sequences, (it can be for different integers, we can use n for sequence A and x for sequence B)

Then we want to find:

aₙ = bₓ

where n and x are integer numbers.

Then we will heave:

3*n^2 - 1 = 30 - x^2

To find the pair, we could isolate one of the variables, then input different integers in the other variable and see if the outcome is also an integer.

Let's isolate n.

3*n^2 = 30 - x^2 + 1

3*n^2 = 31 - x^2

n^2 = (31 - x^2)/3

n = √( (31 - x^2)/3)

Now let's input different values for x, and see if the outcome is also an integer, notice that x is in a negative term inside a square root, then we have only a few values of x such that the equation can be true.

Then let's start with x = 1.

n(1) = √( (31 - 1^2)/3) = √(30/3) = √10

We know that √10 is not an integer.

now with x = 2,

n(2) = √( (31 - 2^2)/3) = √( (31 - 4)/3) = √(27/3) = √9 = 3

then if x = 2, we have n = 3.

Both of them are integers, then we get:

a₂ = 3*(3)^2 - 1 = 27 - 1 = 26

b₃ = 30 - 2^2 = 30 - 4 = 26

The number that belongs to both sequences is 26.

What do you call a female bug that floats math worksheet answer key?

Elena L [17]

Answer to this problem will depend upon the set of questions given with the worksheet or page having question "What do you call a female bug that floats math worksheet answer key?".

You haven't provided the set of questions but i can explain about how to get the answer of the name of bug in that sheet.

Look at the sample picture of similar problem that is attached with the answer. You have to solve the given set of problem and fill the correct matching answer in the blank box.

Say answer of first problem is choice named "T" then fill the letter "T" in the blank box numberd "1".

Same way solve other problem and fill correct name of the letter in each blank boxes.

Now rearrange letters in your answer box in increasing order of numbers 1 to 15. The resulting name will be the final answer for the name of the bug.
