1. The Exponent Rule for dividing like bases states that when dividing exponential expressions with the same base, you subtract the exponents (a^m / a^n = a^(m-n)).
2. The words "divided by" or "divide" generally indicate that a division operation is involved.
3. "How many times larger" implies comparing the size or quantity of two numbers, which can be interpreted as a division problem to determine the ratio between the two numbers.

A projectile is launched into the air from the ground. The table shows the height of the projectile, h(t), at different times.
Time: 5, 10, 15, 20, 25, 30, 35
Height: 1,353, 2,460, 3,323, 3,940, 4,313, 4,440, 4,323
Estimate the amount of time in seconds it took for the projectile to reach the ground.
A. 10 seconds
B. 60 seconds
C. 175 seconds
D. 85 seconds

D. 85 seconds
To estimate the amount of time it took for the projectile to reach the ground, we need to look at the height values in the table. The height decreases as time progresses, so we need to find the point where the height becomes 0 (ground level).
From the table, we can see that the height reaches its lowest point of 0 at time 35 seconds. Therefore, it took 35 seconds for the projectile to reach the ground.
The closest answer choice is D. 85 seconds, which is the correct estimate in this situation.
