Answer:
3 seconds.
Step-by-step explanation:
f(t) = height of the disc = -18t^2 + 42t + 36.
This equals zero when it completes its path, so:
-18t^2 + 42t + 36 = 0
-6(3t^2 - 7t - 6) = 0
-6 (3t + 2)(t - 3) = 0
t = 3 seconds (We ignore the negative zero).
Answer: Yes
Step-by-step explanation:
Given
Once around park measures 420 yards
Todd needs to complete 5 miles
He runs 30 times during the week
We know, 
for 30 rounds, distance is
In miles, it is
As he runs more than the target. Therefore, he completed his target of 5 miles.
Answer: 
<u>Step-by-step explanation:</u>

- y: total bill
- m: rate (fee per mile)
- x: number of miles
- b: flat rate
60 = 3x + 14
46 = 3x
