Does anyone know what the simplest form is? Will give brainiest

Ahat [919]

Hello from MrBillDoesMath!

Answer:

Choice B.

Discussion:

From the first step

324 x^6 y^ 8 =

2^2 * 3^4 * x^2 * x^4* y^8

so the fourth root of this is

2 ^(2/4)* 3^(4/4) x^(2/4)* x^(4/4)*y^(8/4) =

2^ (1/2) * 3^1 * x^(1/2) * x^(1)* y^ (2) =

(2x)^(1/2) * 3 * x * y^2 =

3 * x * y^2 * sqrt(2x) =

3 * x * y^2 * ( (2x)^2) ^ (1/4)) =

3 * x * y^2 * (4x^2) ^ (1/4)

which is choice B

Thank you,

MrB

Find m angle ABC<br> Please help

Marina CMI [18]

Answer:

ABC = 35

Step-by-step explanation:

x and 3x-70 are corresponding angle and corresponding angle are equal when the lines are parallel

x = 3x-70

Subtract 3x from each side

x-3x = 3x-70-3x

-2x= -70

Divide by -2

-2x/-2 = -70/-2

x = 35

x = 3x-70 = 35

Solve the formula s=4pi r^2 for r

andrew11 [14]

Answer:

The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4. This is written algebraically as S=4πr2, where S is the surface area, r is the radius, and the value of π is 3.14.

Select Parameter or Statistic to classify each statement.

Annette [7]

Answer:

1) Statistic

2) Parameter

3) Statistic

4) Parameter.

Step-by-step explanation:

Parameter: is a number that describes the whole population.

Statistic: is a number that describes a sample.

The difference is:

50% of the cats are nice (parameter, because talks about all the cats)

out of 100 cats surveyed, 39 are nice (statistic, because talks about a sample of 100 cats)

Then:

1) 85% of those surveyed were in favor of bike lanes.

This only refers to the surveyed people, so this only refers to a sample (and not the population that this sample represents) then this is a statistic statement.

2) Each member of the soccer team has an average of 2 jerseys.

In this case, we are talking about the whole population (the soccer team) then this is a parameter

3) Of the 100 swim teams surveyed across America, 23 practice 10 hours a week.

Here the information is about the sample (only 100 swim teams). So here the correct option is statistic.

4) The golf team's average score is 79

Here the information is about the average score for the entire golf team, so this information is about all the population in the golf team, then in this case the correct option is parameter.

How do you do this. Please give a full answer and explain why.

<u>L</u><u>a</u><u>w</u><u> </u><u>o</u><u>f</u><u> </u><u>E</u><u>x</u><u>p</u><u>o</u><u>n</u><u>e</u><u>n</u><u>t</u>

$\displaystyle \large{ {a}^{ - n} = \frac{1}{ {a}^{n} } }$

Compare the terms.

$\displaystyle \large{ {a}^{ - n} = {( - 2)}^{ - 3} }$

Therefore, a = -2 and n = 3. From the law of exponent above, we receive:

$\displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{ {( - 2)}^{ 3} } }$

<u>E</u><u>x</u><u>p</u><u>o</u><u>n</u><u>e</u><u>n</u><u>t</u><u> </u><u>D</u><u>e</u><u>f</u><u>.</u> (For cubic)

$\displaystyle \large{ {a}^{3} = a \times a \times a }$

Factor (-2)^3 out.

$\displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{( - 2) \times ( - 2) \times ( - 2)}}$

(-2) • (-2) = 4 | Negative × Negative = Positive.

$\displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{4 \times ( - 2)}}$

4 • (-2) = -8 | Negative Multiply Positive = Negative.

$\displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{ - 8}}$

If either denominator or numerator is in negative, it is the best to write in the middle or between numerator and denominators.

Hence,

$\displaystyle \large \boxed{ {( - 2)}^{ - 3} = - \frac{1}{ 8}}$

The answer is - 1 / 8
