What is the correct radical form of this expression?
Sophie [7]

Option A. \sqrt[5]{\left(32 a^{10} b^{\frac{5}{2}}\right)^{2}} is the correct radical form.

Step-by-step explanation:

Step 1:

The numerator of the exponential is kept where it is whereas when converting an exponential into a radical, the denominator becomes the root of the variable.

The numerator of the exponential is 2 while the denominator is 5.

Step 2:

So the numerator is kept where it is while the denominator, 5 becomes the root of the variable.

Out of the given options, options 2, 3 and 4 have square roots so they cannot be the answers. Option 1 has a root to the power of 5, so it is the correct radical form.

So option 1 is the right answer.

Explain in a complete sentence if the point (2,-4) is the solution to the system of equations. Show your work in the space provi
slavikrds [6]

Answer:


Step-by-step explanation:

2x - y = 8

<u> x + y = - 2 </u>

3x       = 6

3x /3    = 6/3   Dividing bot sides by 3 to find x.

x = 2

Plug in the value of x to find y.

2 ( 2) - y = 8

4 - y = 8

-y = 8 - 4

- y = 4

y = -4

The solution: ( 2, -4)

Can someone please help me with this ?? im really confused but i need to pass this test!
Keith_Richards [23]

Answer:

84^{\circ}

Step-by-step explanation:

The measure of an inscribed angle is exactly half the measure of the arc it forms. Thus, we have the following equation:

2(7x-7)=9x+21

Solving, we get:

2(7x-7)=9x+21,\\14x-14=9x+21,\\5x=35,\\x=7

Plugging in x=7 into 9x+21:

\widehat{DG}=9(7)+21,\\\widehat{DG}=63+21,\\\widehat{DG}=\boxed{84^{\circ}}

You have been offered a project paying $300 at the beginning of each year for the next 20 years. what is the maximum amount of m
AfilCa [17]
This is a simple problem with some quick addition and subtraction, and a bit of multiplication.

First we figure out how much money you're spending in total, which is $300 each year, for 20 years, so 300 x 20 = 6,000. Now, since the problem is asking for a maximum amount for percentage rate, this means we find the 9% for all 20 years combined and not individually. 9% of 6,000 is of course 540, so if we subtract 540 from 6,000, we get 5,460.

This means your answer is $5,460
