Suppose an x-y axis is superimposed on the map with its origin at des moines, iowa. also suppose a cold front is passing through the us at noon having shaped roughly like a parabola with its vertex at des moines, iowa ad a vertical stretch/ shrink factor of 1/20 if the independent varaible is measured in hundreds of miles. what type of function are you working with. how do you know? is the leading coefficient positive or negative? how do you know?

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
