For this case, we must find the product given by the following roots:

\sqrt [5] {4x ^ 2} * \sqrt [5] {4x ^ 2}

Let a, b belong to the real numbers, and let m, n belong to the natural numbers, then:

\sqrt [n] {a} * \sqrt [n] {b} = \sqrt [n] {a * b}

So, we have:

\sqrt [5] {4x ^ 2} * \sqrt [5] {4x ^ 2} = \sqrt [5] {4x ^ 2 * 4x ^ 2} =\\\sqrt [5] {16x ^ 4}

Answer:

Option B

The equations of two functions are y =-28x + 8 and y=-29x + 7. Which function is changing more
irinina [24]

<u>Answer:</u>

y=-29x+7 is changing more quickly.

<u>Step-by-step explanation:</u>

This is because the equation y=-29x+7 has a larger slope. The speed of change is determined entirely by the slope; the larger the slope, the faster the line goes up or down. It doesn't matter if it's negative or positive. -29 is the slope of the equation.

GH bisects CF. CF = 2y-2 and CD = 3y -11. find CD
love history [14]

Answer:

CD = 4

Step-by-step explanation:

GH bisects CF  <u><em>means</em></u>  CF = 2 CD

CF = 2 CD

⇔ 2y - 2 = 2×(3y - 11)

⇔ 2y - 2 = 6y - 22

⇔ 22 - 2 = 6y - 2y

⇔ 20 = 4y

⇔ y = 5

<u>Calculating CD ,For y = 5</u> :

CD = 3y - 11

     = 3(5) - 11

     = 15 - 11

     = 4

The fuel efficiency for a 2007 passenger car was 31.2 mi/gal. For the same model of car, the fuel efficiency increased to 35.6 m
Ierofanga [76]

We have been given that fuel efficiency for a 2007 passenger car was 31.2 mi/gal and the same model of car, the fuel efficiency increased to 35.6 mi/gal in 2012. Also, the gas tank for this car holds 16 gallons of gas.

We need to write a function and graph a linear function that models the distance that each car can travel for a given amount of gas up to one tankful.

Let represent the functions as d_{1}(x) and d_{2}(x)  where d_{1} and d_{2} represent the distances traveled by car in years 2007 and 2012 and x represents the number of gallons. Therefore, we can express the required functions as:

d_{1}(x)=31.2x \text{ and } d_{2}(x) = 35.6x

Domain of both these functions are [0,16] and ranges are [0,499.2] and [0,569.6] respectively for years 2007 and 2012.

The difference function will be:

f(x)=35.6x-31.2x\\&#10;f(x)=4.2x

f(16)=4.2*16=67.2

Domain of this function is [0,16] and range is [0,67.2].

The graphs are shown below.
