Answer:
6
Step-by-step explanation:
a^2 + 8^2 = 10^2
a^2 + 64 = 100
a^2 = 36
sq root of a = sq root of 36
a = 6
a. define variables for the quantities that are changing (be specific).
We define variables:
t = time in second
d = distance traveled
The variables that are changing are t and d.
As the time increases, the distance decreases.
b. what does it mean to say bob walks at a constant speed of 9.3 feet per second?
It means that for every second that passes, Bob walks 9.3 feet.
c. consider the formula d = 4320 - 9.3t i. what does t represent? ii. what does 9.3t represent? iii. what does d represent?
For this case we have:
t = represents the time in seconds
9.3t = represents the distance traveled by Bob
d = represents the distance Bob must travel to get to the bus stop.
Option 1 =$497.5 option 2 =$494.5 option 3 =$50.5
