For the diagonal of the floor:
20^2 + 48^2= c^2
400+2304= c^2
c=52
For the diagonal of the cube:
52^2 + 10^2 = c^2
2704+100=c^2
c=52.95
Rounded= 53
Tell me if this helps!!!
The second one because domain refers to x, and since at (-3,-4) the point is hollow, the sign should be < without the line under it
Answer: First Option
The slope is −0.4. Starting at 3.8, the GPA will decrease by 0.4 for every text sent in class.
Step-by-step explanation:
The equation of a line has the following form

Where m is the slope of the line and b is the intercept with the axis of the y
In this case, the equation is:

Observe that

So if x represents the number of texts sent during classes, this means that 
When x increases by one unit then y decreases -0.4. For example when
then 
Then the greatest value it can take the GPA is 3.8. Therefore we can say that the function starts at y = 3.8.
The answer is the first option
