In mathematics, a percentage is a number or ratio expressed as a fraction of 100. A common symbol for a percentage is this symbol "%." Some abbreviations for it can be, "pct," or "pc."

Remember though that a percentage had no unit of measurement as it is a dimensions number.

If f(x) = -4x + 2 and g(x) = sq root X – 8,<br>what is (fºg)(12)?

Anettt [7]

Answer:

$(fog)(12)=-6$

Step-by-step explanation:

Recall that the notation: $(fog)(12)$ is the same as: $f(g(12))$ which means the value of the function f when you give it as input the value obtained by evaluating g(12).

Therefore, we need to start finding what g(12) is using the definition :

$g(x)=\sqrt{x-8}$ and evaluating it as x = 12.

$g(x)=\sqrt{x-8}\\g(12)=\sqrt{12-8}\\g(12)=\sqrt{4}\\g(12)=2$

So now we use this answer "2" as input for f(x):

$f(x)=-4x+2\\f(2)=-4(2)+2\\f(2)=-8+2\\f(2)=-6$

Therefore, $(fog)(12)=-6$

Irene tiene una colección de 50 dvd de películas de 90 minutos de duración cada una .Si el precio de cada uno era de 11€ , ¿cuan

Rainbow [258]

To solve this problem you must apply the proccedure shown below:

1. She has a total of 50 DVDs of 90 minutes each one of them. The cost of each DVD was 11€.

2. Therefore, to calculate the total cost of the collection, you must multiply the cost of each DVD by the total number of them:

$total=(11)(50)=550$ €

3. To calculate the total minutes of the collection, you must multiply 90 minutes by the total number of DVDs:

$(90min)(50)=4500min$

Therefore, the answer is: 550€ and 4500 minutes.
