√(64y^16)

= √64 √(y^16)

= 8 √(y^16)

Using the Radical Rule of exponents:
(n√a^m) = a^(m/n)

= 8•y^(16/2)

= 8y^8

Therefore, the correct answer is 8y^8.

Vitek1552 [10]

Answer:

a > m/bp

Step-by-step explanation:

flip the equation

abp > m

divide both sides with bp

abp/bp > m/bp

a > m/bp

Which of the following inequality should be graphed with a dashed line? Select all that apply.

AURORKA [14]

Answer:

B, D

Step-by-step explanation:

Any inequality that does not include the "or equal to" case will be graphed with a dashed line.

<h3>Application</h3>

The "or equal to" case is included when the inequality symbol is one of ≤ or ≥. When symbols > or < are used, the boundary line of the solution space is dashed (or the end point on the number line is an open circle).

The inequalities that will be graphed with a dashed line are ...

2x -4y < 12 . . . . choice B
x +7 > -1 . . . . . . .choice D

Alabama has about 2.51 million acres of cropland Florida has about 1.15 times as much cropland as Alabama how much crop land doe

aev [14]

Answer: Florida has 2.8865 million acres of cropland .

Explanation:

Since we have given that

Length of acres of cropland Alabama has = 2.51 millions

According to question, we have Florida has about 1.15 times as much cropland as Alabama has ,

So,

Length of acres of cropland Florida has is given by

$2.51\times 1.15=2.8865\text{ million acres }$

So, Florida has 2.8865 million acres of cropland .

Statements that are true for a cylinder with radius r and height h.

vampirchik [111]

Answer:

Only the second and third statements are correct:

Doubling r quadruples the volume.

Doubling h doubles the volume.

Step-by-step explanation:

The volume of a cylinder is given by:

$\displaystyle V=\pi r^2h$

We can go through each statement and examine its validity.

Statement 1)

If the radius is doubled, our new radius is now 2r. Hence, our volume is:

$\displaystyle V=\pi (2r)^2h=4\pi r^2h$

So, compared to the old volume, the new volume is quadrupled the original volume.

Statement 1 is not correct.

Statement 2)

Using the previous reasonsing, Statement 2 is correct.

Statement 3)

If the height is doubled, our new height is now 2h. Hence, our volume is:

$V=\pi r^2(2h)=2\pi r^2h$

So, compared to the old volume, the new volume has been doubled.

Statement 3 is correct.

Statement 4)

Statement 4 is not correct using the previous reasonsing.

Statement 5)

Doubling the radius results in 2r and doubling the height results in 2h. Hence, the new volume is:

$V=\pi (2r)^2(2h)=\pi (4r^2)(2h)=8\pi r^2h$

So, compared to the old volume, the new volume is increased by eight-fold.

Statement 5 is not correct.
