The value of 82 is between which two integers?
hoa [83]

Hey there!

Let's look at the squares of all of our answer options. We will compare them to eighty two to see which it belongs in.

A. 36 and 49.

B. 49 and 64.

C. 64 and 81.

D. 81 and 100

As you can see, 82 is in between 81 and 100, so the answer is D. 9 and 10.

Also, the square root of 82 is about 9.05, and this fits our answer.

Have a wonderful day!

Which number satisfies the inequality 9h + 15 > 55?
zalisa [80]

When you say "Which number ...", I expect to see a list of choices at the
end of the question, and I get very upset when there's nothing there.

                                            9h + 15 > 55

Subtract  15  from each side:          9h > 40

Divide each side by  9 :                  <em>  h > 40/9</em>

Any number greater than (4 and 4/9) satisfies the inequality.

Which expression is equivalent to sec^2x − 1? a. cot2x b. tan2x c. csc2x d. cos2x
Nesterboy [21]
Sec^2 x - 1 = tan^2x

Proof:
Sec^2x = 1+ tan^2x

1/cos^2x = 1 + sin^2x/cos^2x

<span>1/cos^2x - sin^2x/cos^2x = 1
</span>Using common denominator:
(1-sin^2x)/cos^2x = 1
sin^2x + cos^2 x = 1
cos^2 x = 1 - sin^2x
Substituting : 
cos^2x/<span>cos^2x = 1
</span>1 = 1
Left hand side = right hand side

Which is equivalent to (10)^(3/4)x?
ivann1987 [24]

Answer:

Option B is correct.

Step-by-step explanation:

10^{(3/4)x}

We need to write the above equation in square root form.

We know that 1/4 = \sqrt[4]{x}

So, 10^{(3/4)x} can be written as:

(\sqrt[4]{10})^{3x}

Option B is correct.
