Answer:
Step-by-step explanation:
9 + 12m = 6 + 15m - 15
9 + 12m = 15m - 9
9 - 3m = -9
-3m = -18
m = 6
Csc is 1/sin so it is undefined where sin = 0. of your choices only A fits
Answer:
Step-by-step explanation:
To answer this we need only know that negative parabolas are upside down, so by definition, it has a max point at the vertex. To find the vertex (h, k), the easy way to do this is to fill in the following expressions for h and k and solve:
and (These are derived from the quadratic formula). Filling in knowing our a = -1, b = -7, c = 12:
and
so the vertex (aka max height occurs at . Depending upon what is meant by stating the max value, we may only need to state the k value (which is the same as the y coordinate, which is an up or down thing as opposed to the x value which is a side to side thing). The domain is all real numbers, as is the case for all x-squared parabolas, and the range is
R = {y | y ≤ 97/4}
I can't see your choices so match them up from these answers to the ones in the list of choices.
Answer:
80 minutes or 1 hr 20 min
Step-by-step explanation:
This problem is proportional so if Victor washed 2 cars in 8 minutes, he can wash 1 car in 4 minutes. Therefore, 20 x 4 = 80 which is how long it would take him to wash 20 cars.
