The 4th roots of a^12 = a^3 so we can take out a^3
4th root of 144 = 4th root of 9 * 2 so we can also take out 2

The answer is the first choice.

4sqrt(144a^12b^3

factor out 16:

4sqrt16*9a^12b^3

rewrite 16 using a power"
4 sqrt(2^4*9a^12b^3)

rewrie a12 as (a^3^4)

4sqrt( 2^4(a^3)^4 x 9b^3)

rewrite 2^4(a^3)^4 as (2a^3)^4

4sqrt((2a^3)^4 *9b^3)

pull terms out from under the radical:

2a^3 4sqrt(9b^3)

Answer is A

brilliants [131]

Answer:

97.6% of the trees will have diameters between 7.6 and 18.6 inches.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 12 inches

Standard Deviation, σ = 2.2 inches

We are given that the distribution of diameter of tree is a mound shaped distribution that is a normal distribution.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

P(diameters between 7.6 and 18.6 inches)

$P(7.6 \leq x \leq 18.6) = P(\displaystyle\frac{7.6 - 12}{2.2} \leq z \leq \displaystyle\frac{18.6-12}{2.2}) = P(-2 \leq z \leq 3)\\\\= P(z \leq 3) - P(z < -2)\\= 0.999 - 0.023 = 0.976= 97.6\%$

$P(7.6 \leq x \leq 18.6) = 97.6\%$

97.6% of the trees will have diameters between 7.6 and 18.6 inches.

Consider the line -6x-2y=-4.

Rzqust [24]

Answer:

Parallel Slope: -3 Perpendicular Slope: 1/3

Step-by-step explanation:

First, solve for y to get the simplified equation for the line.

Once you solve, the equation should be y=-3x+2

Seeing this, we know that the slope of this line is -3. A line parallel will have the same slope as the original equation, and a line perpendicular will have a slope that is the opposite reciprocal.

Hope that helps!

Which type of parent function is f(x) =^3cubed x

sergij07 [2.7K]

Answer:

Cube Root

Step-by-step explanation:

Because there is a 3 outside the symbol.

That means the equation is stating: y * y * y = x

Hope this helps :)
