Answer:
The potato is 224 feet in the air after 2.75 second on the way up and after 5 seconds on the way back down.
Step-by-step explanation:
Given : A potato launched by a particular potato gun has a height described by 
.
To find : When is the potato 224 feet in the air?
Solution :
When the potato is 224 feet in the air i.e. 
Substitute in the equation ,
Applying quadratic formula, 
Here, a=4, b=-31 and c=55
The potato is 224 feet in the air after 2.75 second on the way up and after 5 seconds on the way back down.
Answer:
1/3m+L>8 (TAKE 1/3M to the other side of the inequality)
L is greater than or equal to 8 - 1/3m
Step-by-step explanation:
Answer:
5
Step-by-step explanation:
The slope is given by
m = (y2-y1)/(x2-x1)
-3/10 = (-5--8)/(-5-x)
-3/10 = (-5+8)/(-5-x)
Using cross multiplication
-3 (-5-x) = 10*(-5+8)
Simplify
-3(-5-x) =10(3)
Divide by -3
-3/-3(-5-x) =10(3)/-3
-5-x = -10
Add 5 to each side
-5-x+5 = -10+5
-x=-5
Divide by -1
x=5
It would be 29 or if you multiply it would be different
The rate of change of stamp collection was $57.5 per year.
Rate is comparison of two related quantities.
Often the second quantity is time (per second, per hour, etc) but it can be anything.
Can be in the style "this per that" or as a single number calculated using division.
Example: Sam makes 3 pancakes every 6 minutes, that is a rate of:
• 3 pancakes per 6 minutes
• 0.5 pancakes per minute
• 30 pancakes per hour
• an hourly rate of 30
By formula the rate of change = Change in cost/ Time taken
=( $980 - $420)/ 8years
= $460/ 8 years
= $57.5 per year
Thus the rate of change of stamp collection was $57.5 per year.
