$log_4(y+2)=3$
raise each side to base 4
$4^{log_4(y+2)}=4^3$
simplify
$(y+2)}=64$ using the law of logarithms $a^{log_ab}=b$
=>
y=62

Answer:

$a = 2 , f(2)=9$

$b = 4 , f(4)=64$

And replacing the data into the average rate formula we got:

$m = \frac{64-9}{4-2}= 27.5$

And then the best answer for this case would be:

C. 27.5

Step-by-step explanation:

For this cae we know that the average rate of change of a function is given by this general expresion:

$m = \frac{f(b) -f(a)}{b-a}$

For this special case from the info of the table we have:

$a = 2 , f(2)=9$

$b = 4 , f(4)=64$

And replacing the data into the average rate formula we got:

$m = \frac{64-9}{4-2}= 27.5$

And then the best answer for this case would be:

C. 27.5

The number to which a base is raised to is called the _exponent_ This tells you how many times to multiply the base together.

Answer:

<em>The total percentage discount was 19%</em>

Step-by-step explanation:

<u>Percentages</u>

Suppose the original price of the shirt was x.

A discount of 10% reduces the price by:

10*x/100 = 0.1x

Thus, the discounted price is:

x - 0.1x = 0.9x

The second discount reduces the price by:

10*0.9x/100 = 0.09x

The new discounted price is:

0.9x - 0.09x = 0.81x

With respect to the original price, the last discounted price has been discounted by:

x - 0.81x = 0.19x

This means the total percentage discount was 0.19*100 = 19%.

The total percentage discount was 19%
