a. y = 0.795x2 + 3.796x + 20.180
b. y = -0.795x2 - 3.760x + 20.180
C. y = -0.875x- 3.596x + 20.179
d. y = -0.795x2 - 3.796x + 20.180

Explain step-by-step how to simplify -5(2x – 3y + 6z – 10).

The krasnapolski is a top-of-the-line hotel in amsterdam, the netherlands. among their many services, they rent bicycles to guests. the bicycle checkout is open 24 hours per day 7 days per week and has 50 bicycles on hand. on average, 10 guests request a bicycle each day, arriving completely randomly at all times of the day during the spring and summer seasons. guests keep bicycles for four days on average, with a standard deviation of two days. how long does a guest on average have to wait for a bike? a. approximately 24 hours b. approximately 0.033 hours c. approximately 4 days d. approximately 47 minutes

Find the zeros of each function. f(x) = 6x^2 - 7x - 20
