Please tell me if I am wrong because I'm not 100% sure on this. Hope it's right and that it helped you.
Answer:
The average speed over the interval from 9 A.M. to 3 P.M. is 2.5 mph.
Explanation:
We can calculate the average speed as:
s = (s₁ + s₂) / n = (5 mph + 0 mph) / 2 = 2.5 mph
where:
s=average speed over the entire interval (9 A.M. to 3 P.M.)
s₁: average speed during the hiking (interval from 9A.M. to 12 A.M.)
s₂: average speed during the lunch (interval from 12 P.M to 3 P.M.)
n: number of intervals
Sound waves can be used in a similar way to "see" things. After turning on a sound source, we can look at the pattern of reflected sound waves that bounce back to us. Our own ears and brain don't process sound into mental pictures.
Answer: See below
Explanation:
Therefore, both cars move with a velocity of 18.099 m/s in the direction of 15.945° downward from the x-axis (east)
D^2 = p^2 + q^2 - 2 pq cos D
d^2 = (4.24)^2 + (4.24)^2 - 2. (4.24) (4.24) cos 68
d^2 = 2 (4.24)^2 - 2. (4.24) (4.24) cos 68
d = 4.74
so the answer will be letter. C
hope this helps
