I ONLY HAVE 2 MINUTES HELP? 1.The revenue R you receive for selling pizza slices depends on the price p that you charge per slice and is modeled by R = -16p2 + 80p + 5. What is the domain of this function?
A) p ≥ 0
B) all real numbers
C) 0 ≤ p ≤ 5.06
D) 2.5 ≤ p ≤ 105
2.
Determine the range of the function.
y = -2x^2 + 3
A) all real numbers
B) all integers less than or equal to 3
C) all integers greater than or equal to 3
D) all real numbers less than or equal to 3

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

step-by-step explanation:

divided 3/4 and 6

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
