Answer:
p=9.6
Step-by-step explanation:
21/25
Change to decimal:-
Divide numerator by denominator.
21/25
21 ÷ 25 = 0.84
21/25 = 0.84
Change to a percentage:-
0.84 × 100 = 84
21/25 = 0.84 = 84%
Your answer should be A. i may be wrong, but my work calculated to a negative
X = -b/2a
x = -8/4
x = -2
Plug -2 in for x and solve for y
y = 2(-2)^2 + 8(-2) -3
y = 8 -16 -3
y = -11
Vertex (-2, -11)
Acceleration:
change in velocity over time.
in the first 15 minutes the change is 50km/h.
divide this by 0.25 (hours) and get a result of. 200km/h^2.
the distance is the area under the graph.
for the average speed, get your total distance (what you worked out in part b) and divide by the time (2 hours)
