Radical 6x^2 multiplied by radical 18x^2

Alina [70]

Does radical mean square root?, because radical can mean square root, cube root, fourth root, etc.

Well, I'm going to assume that radical = square root

So, if you have two square root functions, you can multiply the numbers within the square root, so you now have $\sqrt{48x^4}$ , which I'm not sure if you want it simplified or not

A media company wants to track the results of its new marketing plan, so the video production manager recorded the number of vie

Alisiya [41]

Answer:

$f(x)=5120(1.25)^{x}$

Step-by-step explanation:

As per the given question

As we know that

f(x) and x are related by following equation

$f(x)=a( {b})^{x}$

where

b is the common ratio

Now first we have to compute the value for b which are as follows

$\frac{6400}{5120}= 1.25$

$\frac{8000}{6400}= 1.25$

Like if we take the ratio by this method than it comes 1.25

Therefore the common ratio, b = 1.25

So,

a = 5,120

Hence, the equation which model the relationship between the number of weeks and the number of viewers is

$f(x)=5120(1.25)^{x}$

Factor the expression.<br> 9y^2– 36

Nata [24]

Answer:

Answer: 9 (y - 2) (y + 2)

Step-by-step explanation:

Factor the following:

9 y^2 - 36

Factor 9 out of 9 y^2 - 36:

9 (y^2 - 4)

y^2 - 4 = y^2 - 2^2:

9 (y^2 - 2^2)

Factor the difference of two squares. y^2 - 2^2 = (y - 2) (y + 2):

Answer: 9 (y - 2) (y + 2)

Solve the following system of equations using substitution.

ollegr [7]

To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.

$5x - 4y = -3$

$5x - 4(3x-5) = -3$

$5x -12x+20=-3$

$-20$ $-20$

_______________

$5x-12x=-23$

$-7x=-23$

___ ____

$-7$ $-7$

$x=3.29$ (rounded)

Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.

$y = 3x-5$

$y = 3(3.29)-5$

$y = 9.87-5$

$y = 4.87$

So, your final answer would be (3.29, 4.87).
