The equation is $5^{3}$ × $5^{-2}$

First, you need to solve the bases/exponents

$5^{3}$ is 5×5×5=125

Then you solve the second base/exponent but know that with negative exponents, you divide 1 by the number rather than multiplying

$5^{-2}$ = 1÷5÷5=.04

So now the equation is 125×.04=5

Answer: 5

What is the measure of o

Helga [31]

Answer:

Step-by-step explanation:

We need the formula for arc length (in radians) to solve this problem. The formula is:

$s=r \theta$

Where

s is the arc length

r is the radius of the circle

$\theta$ is the intercepted angle

In this diagram, we can see that $\theta$ is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20

Also, if we look, we see that the radius is 5 cm, so r = 5

Now, we substitute into formula and find $\theta$ :

$s=r\theta\\20=5\theta\\\theta=\frac{20}{5}\\\theta=4$

This is given in radians, so $\theta$ is 4 radians

D is the correct answer choice.

Can someone help lol free points btw

Answer:

The correct answer would be C

Step-by-step explanation:

Looking at the data, you can tell that the first two are going to be wrong. The minimum is 1, and the maximum is 5.

A mode, by definition, is the number that appears most in the data. According to answer D, 3 appears 3 times in the data. That is incorrect, as 3 only appears twice in the data.

This leaves only answer C. We need to make sure it's correct. The answer mentions the mean as a value between 2 and 3. Mean is the average. To find the average, you must add all the values together first.

1 + 2 + 5 + 3 + 2 + 2 + 5 + 3 = 23

Then, you must divide the value by the number of data given. There are 8 numbers here, so you must divide 23 by 8.

23/8 = 2.875

2.875 is between the numbers 2 and 3 like answer C said, so C is correct.

Is -5/11 equivalent to -5/-11 ? Why or why not?

faltersainse [42]

No, -(5/11) is equivalent to -5 all over 11 so -5/11. You cannot change the denominator
