Answer:
The truck is hauling 3/4 of a full load
Step-by-step explanation:
we know that
2/3 ton of gravel represent the 100% of a full load
Find out how much of a full load the truck is hauling with 1/2 ton of gravel, using proportion
Let
x ----> the percentage of a full load
Convert to fraction number
therefore
The truck is hauling 3/4 of a full load
The domain and the range are 0 ≤ ∅ ≤ 2π and -1 ≤ cos(∅) ≤ 1, respectively.
<h3>The domain and the range</h3>The domain is the set of input values i.e. the ∅ values.
On the table, we can see that the ∅ value is from 0 to 2π.
This means that the domain is 0 ≤ ∅ ≤ 2π
On the other hand, the range is the set of output values i.e. the cos(∅) values.
On the table, we can see that the cos(∅) value is from -1 to 1.
This means that the range is -1 ≤ cos(∅) ≤ 1
Hence, the domain and the range are 0 ≤ ∅ ≤ 2π and -1 ≤ cos(∅) ≤ 1, respectively.

Answer:
1. Attached
2. 25 mph
Step-by-step explanation:
1. Tim travels first 15 minutes hour at average speed of 40 mph and passed
2. Time stops for 25 minutes (distance traveled = 0 miles).
3. He then completes the journey at an average speed of 45 mph. The total journey time is 1 hour, then he was travelling at 45 mph for
and covered
The distance-time graph for his journey is attached.
Find the average speed for the whole journey:
