Answer:
a. 30 meters per second
b. -10 meters per second
Step-by-step explanation:
a. Average rate of change for the height from 0 to 6.6 secs can be calculated using the formula,
Thus,
Where,
Plug in the values into the formula:
b. Average rate of change for the height from 8.8 to 13.2 secs = tex] m = \frac{H(b) - H(a)}{b - a} [/tex]
Where,
Plug in the values:
Answer:
w=120°
x=45°
y=30°
Step-by-step explanation:
AT=PR, AR=PT
Therefore, y=30°
y+45°=x+30°
x=45°
In triangle:
y+30°+w=180°
w=120°
Hope it helps! :)
Answer:
120
Step-by-step explanation:
20 x 6 = 120 which will be subtracted by his balance. hence the change.
D because ugh I don’t feel like explaining
