The apples would cost (8.9x.99) $8.81. So, 10-8.81 is about 1.19. They would get $1.19 back

The logarithmic expression $\rm log_w\dfrac{(x^2-6)^4}{\sqrt[3]{x^2-8}}$ can be expressed as $\rm 4log_w{(x^2-6)} - {\dfrac{1}{3}}log_w(x^2-8)$ .

Given to us

$\rm log_w\dfrac{(x^2-6)^4}{\sqrt[3]{x^2-8}}$

<h3>Which expression is equivalent to $\rm log_w\dfrac{(x^2-6)^4}{\sqrt[3]{x^2-8}}$ ?</h3>

To solve the problem we will use the basic logarithmic properties,

$\rm log_w\dfrac{(x^2-6)^4}{\sqrt[3]{x^2-8}}$

Using the logarithmic property $\rm log_a\dfrac{x}{y} = log_ax-log_ay$ ,

$=\rm log_w{(x^2-6)^4} - log_w{\sqrt[3]{x^2-8}}$

Using the exponential property $\sqrt[m]{a^n} = a^{\frac{n}{m}}$ ,

$=\rm log_w{(x^2-6)^4} - log_w(x^2-8)^{\dfrac{1}{3}}$

Using the logarithmic property $\rm log_aB^x = xlog_aB$ ,

$=\rm 4log_w{(x^2-6)} - {\dfrac{1}{3}}log_w(x^2-8)$

Hence, the logarithmic expression $\rm log_w\dfrac{(x^2-6)^4}{\sqrt[3]{x^2-8}}$ can be expressed as $\rm 4log_w{(x^2-6)} - {\dfrac{1}{3}}log_w(x^2-8)$ .

Help please I need to turn it in

Answer:

7.C

9.C

10.6x+5=15

Step-by-step explanation:

7 is trying to trick you. You have to divide 43.20 by 5 instead of 4. They split the tickets, but they gave some to her too.

For 9, add 2 to both sides. You will get 4x= 16. Then divide both sides by 4. You will get 4 as your answer.

For 10, on the left side there are 6 boxes with the letter x on it. This means 6x. There is also 5 circles with the number 1 on it. Then you will have 6x+5. Then the right side. There are 15 1’s total. Add them all up and you get 6x+5=15. In this question, you don’t have to answer it.

Man I wish I had your homework.

If the simple interest on $1000 for 9 years is $630, then what is the interest rate?

nalin [4]

Answer:

0.07 or 7%

Step-by-step explanation:

I = Prt

630 = (1000)(9)r

630 = 9000r

r = 0.07
