Answer:
Step-by-step explanation:
Given
(a)distance
speed=1.2 m/s
=64.6 at 3.53 m/s
total time 
=53.83+18.3=72.13 s
Average velocity

(b)total distance
Average velocity

Answer:
D. about 8.5 mi
Step-by-step explanation:
To go from Aesha to Josh, you go 6 units right and 6 units up.
Each unit is a mile, so you go 6 miles right and 6 miles up.
Think of each 6 mile distance as a leg of a right triangle, and the direct distance from one place to the other as the hypotenuse of the right triangle. Use the Pythagorean theorem to find the length of the hypotenuse.
a^2 + b^2 = c^2
The 6-mile legs are a and b. c is the hypotenuse.
(6 mi)^2 + (6 mi)^2 = c^2
c^2 = 36 mi^2 + 36 mi^2
c^2 = 72 mi^2
c = sqrt(72) mi
c = sqrt(36 * 2) mi
c = 6sqrt(2) mi
c = 6(1.4142) mi
c = 8.5 mi
Hi!
<u>For your first question:</u>
When it looks like this, with an exponent, then parentheses, then an exponent, we should multiply the exponents.

<em>P.S. As for your second question, I believe I already answered that on your other question!</em>
Answer:
Son = 14
Father = 42
Step-by-step explanation:
Let son age be x
Father's age is 3x and x + 28
3x = x + 28
2x = 28
x = 28/2 = 14
Father's age is x + 28 = 42
