Answer:

A and C

Step-by-step explanation:

<u>Rewriting for the sake of clarity:</u>

<em>Select all radical expressions that are equivalent to</em> 3^{\frac{4}{7}}

a)(\sqrt[7]{3^{4}})\\b)\sqrt[4]{21}\\c)\sqrt[7]{81}\\d)\sqrt[4]{3^{7}}\\e)\sqrt[7]{12}\\f)\sqrt[4]{3^{7}}

1) According to the Exponents Law, when we have a fraction as an exponent the numerator of it will be the radicand's exponent and the denominator will be the index of it.

3^{\frac{4}{7}}=(\sqrt[7]{3^{4}})

2) We can raise the 3 to the 4th power. And rewrite the radicand as the result of that:

3^{\frac{4}{7}}=\sqrt[7]{3^{4}}=\sqrt[4]{21}

Pleas answer correct answer
Minchanka [31]

Step-by-step explanation:

well, what would you think ?

since the line NO bisects the angle at N (MNO), it bisects also the line MO.

"bisecting" simply means "cutting in half". that means both resulting parts are equally large.

therefore, MO = PO = 8

A trapezoid has an area of 329 square feet. If the bases are 30 feet and 17 feet, what is the height of the trapezoid in feet? F
ExtremeBDS [4]

Answer:

The correct option is C.  14 ft

Step-by-step explanation:

To calculate the height, we will follow the steps below;

Formula is given to be:  h = 2A / b1 +b2

where h = height of the trapezoid   b1 and b2 are the bases of the trapezoid    and A is the area of the trapezoid

From the question given;

Area A =329 feet²      b1 = 30 feet    b2 =17 feet  

We can now proceed to insert the values into the formula

h = 2A / b1 +b2

h= 2(329)  / 30 + 17

h = 658 /47

h=14 feet
