Answer:
Step-by-step explanation:
21-26. a = v - u / t
=> a = 47 - 19 / 5
=> a = 28 / 5
=> a = 5.6 m/s²
27-32. avg. speed = distance / time
=> 40 m / 10 s
=> 4 m/s
33-38. velocity = distance / time
=> v = 150 / 40
=> v = 15 / 4
=> v = 3.75 m/s
The formula of a slope:

We have the points (4, -4) and (k, -1) and the slope m = 34.
Substitute:

So you would just have to divide 20/7 to get the percentage of it.
The answer would be 2.85%.
Answer:
6.9
7.-5
8.-10
Step-by-step explanation:
Answer: 155°
because ∠a and ∠c are 2 opposing angles => m∠a = m∠c = 155°
