Answer:

5 hours and 40 minutes would be class

Step-by-step explanation:

We know that the total time is 7 hours, which in minutes would be:

7 * 60 = 420

420 minutes would be class, now, we subtract the other times that are not to be in class and it would be:

420 - 30 - 50 = 340

So we could say that in class it takes 340 minutes, and if we spend hours it would be:

340/60 = 5.67 hours or also 5 hours and 40 minutes would be class.

leva [86]

Answer: discrete

Step-by-step explanation:

The graph would be discrete, because you can only order a whole number of pizzas. This means you cannot have 0.4 of a pizza or 3/5 of a pizza. Therefore, p can only be whole numbers, so you cannot draw a line through the points, since prices for non-whole pizzas are not possible.

Let f(x)=1/x and g(x)=x^2-2x What two numbers are not in the domain of f o g?
Brrunno [24]

Answer:

First find f o g (x)

f o g (x) = 1 / x² - 2x

To find the numbers which are not in the domain of f o g equate the denominator to zero

x² - 2x = 0

x(x - 2) = 0

x = 0 and x = 2

The two numbers which are not in the domain of f o g are 0 and 2.

Hope this helps.
