Answer:
Distance between automobile and the truck is 100 feet.
Step-by-step explanation:
Speed of the automobile towards the intersection = 30 ft per sec
Speed of the truck that crosses the intersection = 40 ft per sec.
Automobile is 120 feet apart when the truck passes through the intersection.
After 2 seconds distance traveled by the automobile = Speed × time
= 30 × 2
= 60 feet
So the distance of the automobile from the intersection = 120 - 60
= 60 feet
Distance traveled by truck in 2 seconds = 40 × 2
= 80 feet
Now distance between them can be calculated by Pythagoras theorem
Distance = 
= 
= 
= 100 feet
Therefore, after 2 seconds distance between the truck and the automobile will be 100 feet.
Answer:
D is correct (I think).
Step-by-step explanation:
A and C are completely invalid, as A is a linear function and C does not go up in intervals of 25.
Answer C is a linear function and is represented by y=x+1, but there are potential other reasons that it could be considered a linear function.
Answer D cannot be solved by y=mx+b because it is an exponential function.
The correct answer is C:$76.05. Tim would make 135.42 in three months and the total (221.47) minus 135.42 equals 76.05.
