Answer:
45 feet per second
Step-by-step explanation:
To find the average speed of an object, you would have to divide the distance it traveled by the time it took to travel that far. In other words:
The ball traveled 90 feet in 2 seconds the average speed would be:
90f/2s = 45 f/s = 45 feet per second
The ball would have traveled at an average speed of 45 feet per second.

Below is a scale drawing of the town swimming pool. In the drawing, the longest side of the
pool has a length of 10 inches. Paco creates a new scale drawing of the pool. In his drawing,
the longest side of the pool has a length of 5 inches. What scale is Paco's new drawing?
A simple way to find this using mathematical methods is to set up a proportion:
Then you would cross multiply getting:
900=10x (then divide by 10 on both sides to get the variable alone)
x=90
So 90 inches will represent 900 miles

Answer:
f(- 3) = 18
Step-by-step explanation:

f(- 3) = (- 3)² - 2(- 3) + 3 = 9 + 6 + 3 = 18
