The instructor wants the profit to be positive, so
f(n) > 0
70n -400 > 0
n - 400/70 > 0
n > 5 5/7
The instructor must enroll at least 6 students to make a profit.
Answer:
17
Step-by-step explanation:
The sum of a polygon's angles is 180° (n − 2), where n is the number of sides. A hexagon has 6 sides, so the sum of the angles is:
180° (6 − 2) = 720°
Therefore:
720 = 8x − 1 + 5x + 36 + 116 + 7x + 19 + 6x − 2 + 110
720 = 26x + 278
26x = 442
x = 17

Answer & Step-by-step explanation:
For this problem, we are going too have to use the distance formula.
We can plug in the coordinate points that we are given to their respectful places.
So, the distance between the pool and the main office is 7.3 miles.
