A: the domain is the interval [0,9460] the range is the interval [0,428875]b: the domain is all real numbers the range is all real numbers c: the domain is all integer values in the interval [0,9460]the range is all multiples of 45.5 in the interval [0,430430]d: the domain is the interval [0,9460]the range is the interval [0,45.50] i'm timed

option c: the domain is all integer values in the interval [0,9460]

the range is all multiples of 45.5 in the interval [0,430430]

Explanation:

1) It is said that the revenue is a funciton of the number of people in attendance.

2) So, the independent variable is the number of people in attendance, and the dependent variable is the revenue in $.

3) The domain is the set of numbers that the independent variable (input) can take; that is the number of people that the stadium is capable of seating. Then it is all the integer values in the interval [0, 9460].

4) The otuputs are calculated as 45.5 times the number of people in attendance, so they are all the integer values in the interval [0, 430.430]. That is the range.

i dont know it

step-by-step explanation:

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
