Answer:

55 degrees (e)

Step-by-step explanation:

This is a trigonometry problem. We are given a right triangle with an unknown angle in which the opposite and adjacent sides of the angle are known (10 and 7). We also know that the tangent of any angle is the length of the opposite divided by the length of the adjacent. If we let the unknown angle be Ф, we can say that tan(Ф) = 10/7. To isolate Ф, all we have to do is take the inverse. In other words, Ф = arctan(10/7). Using a graphing calculator, we find that arctan(10/7) is approximately 55 degrees.

Antonio wants to examine the sales in a restaurant during a period of time from 2 hours before to 2 hours after the peak dinner
Anna007 [38]

Using function concepts, it is found that the domain of the graph Antonio is creating would be: 4 \leq x \leq 8

  • The domain of a function is the <u>set that contains all possible input values</u>.

In this problem, the inputs are the time, between <u>2 hours before and 2 hours after the peak time of 6 pm</u>, hence, it is given by: 4 \leq x \leq 8
