Answer:

see below

Step-by-step explanation:

The recursive function tells you the first term is 1. That is the meaning of ...

$a_1=1$

It also tells you that to find the next term, you multiply this term by 1/2:

$a_2=\dfrac{1}{2}a_1=\dfrac{1}{2}\cdot 1=\dfrac{1}{2}$

And, to find the next term, you multiply this term by 1/2:

$a_3=\dfrac{1}{2}a_2=\dfrac{1}{2}\cdot\dfrac{1}{2}=\dfrac{1}{4}$

Then the first three terms are ...

1, 1/2, 1/4

Which is equivalent to sqrt x^10<br> A. X-5<br> B. X -1/5<br> C. X sqrt 10<br> D. X 1/5<br> E. X^5

Lesechka [4]

<h3>Answer: E) x^5</h3>

$\sqrt{x^{10}} = x^5$

=====================================================

Explanation:

We simply take half of the exponent 10 to get 5. This applies to square roots only.

So the rule is $\sqrt{a^b} = a^{b/2}$

A more general rule is

$\sqrt[n]{a^b} = a^{b/n}$

If n = 2, then we're dealing with square roots like with this problem. In this case, a = x and b = 10.

90° is equal to $\frac{\pi}{2}$ or 1.5707 radians.

Step-by-step explanation:

Step 1:

If an angle is represented in degrees, it will be of the form x°.

If an angle is represented in radians, it will be of the form $\frac{\pi}{x}$ radians.

To convert degrees to radians, we multiply the degree measure by $\frac{\pi}{180}$ .

For the conversion of degrees to radians,

the degrees in radians = (given value in degrees)( $\frac{\pi}{180}$ ).

Step 2:

To convert 90°,

$90 (\frac{\pi}{180} ) = \frac{\pi}{2}.$

$0.5 \pi = 1.5707$ radians.

So 90° is equal to $\frac{\pi}{2}$ or 1.5707 radians.

Hey guys, I know this is a lot so I am offering a lot of points. I was stumped on this paper, I just need a little help on how t

Llana [10]

So for number one, you would have to divide the number by the one being multiplied. I’ll do the first one and you can do the second one, comment if you need help.
(4)*_=-12 —> -12/4 = -3
Check : -3*4 = -12
The answer would be -3.
For the second one, multiply all the numbers first and find the actual answer.
(4)*(-7)*(-1) —> 4 * -7 = -28 —> -28 * -1 = 28
Then multiply their answers.
Evangelina : (-28)*(-1) = 28
Josh : (4)*(7) = 28

Now check who has the right answer and explain why.

For number three, use the letters and plug in the values that are being given to you.

e —> -e
-e * f = -15
-e * g = 6
f * g = -10

Now solve from there!

I really hope I helped, comment if you have any questions:)
