Explanation:
The problem statement tells you the meaning of t. It is minutes after Riko leaves. 0 ≤ t < 52.5 is the answer to the question regarding the interval Riko is behind Yuto. It means Riko is behind Yuto for 52.5 minutes after she leaves their house.
t will not be negative because time moves forward. Here, we're only counting time <em>after Riko leaves the house</em>. A negative value for t would refer to a time before Riko leaves the house, which is irrelevant in this problem.*
_____
* One might argue that Riko is behind Yuto for all values of time <em>after Yuto leaves the house</em>, which would be for -21 < t < 52.5. The concept of "behind Yuto" has no meaning except in that interval.

if their base is the same, the exponents must also be the same for the equation to be true.
Answer:
2.2 × 10³ mm³
Step-by-step explanation:
We have a triangular prism with the following dimensions:
Altitude: 20.5 millimeters
Base: 16 millimeters
Height: 13.3 millimeters
We can calculate the volume of a triangular prism using the following expression.
V = (1/2 × Altitude × Base) × Height
where,
(1/2 × Altitude × Base) is the area of the base
V = (1/2 × Altitude × Base) × Height
V = (1/2 × 20.5 mm × 16 mm) × 13.3 mm = 2.2 × 10³ mm³
