Which situation is best modeled by an exponential function?
the distance a car is from a fixed point if the car was originally 200 feet
from that point and traveled at a speed of x miles per hour
the number of gas stations in a town that had 4 stations in 2010 and x new
stations have opened each year since
the cost to rent a bicycle from a company that charges a flat rate plus x
dollars per day
the amount of a substance remaining after x years if it is decreasing at a
rate of 25% annually

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

answer:   y=2x-3
