Answer:
NO amount of hour passed between two consecutive times when the water in the tank is at its maximum height
Step-by-step explanation:
Given the water tank level modelled by the function h(t)=8cos(pi t /7)+11.5. At maximum height, the velocity of the water tank is zero
Velocity is the change in distance with respect to time.
V = {d(h(t)}/dt = -8π/7sin(πt/7)
At maximum height, -8π/7sin(πt/7) = 0
-Sin(πt/7) = 0
sin(πt/7) = 0
Taking the arcsin of both sides
arcsin(sin(πt/7)) = arcsin0
πt/7 = 0
t = 0
This shows that NO hour passed between two consecutive times when the water in the tank is at its maximum height
Answer:
the first one i think
Step-by-step explanation:
Answer: 50
Step-by-step explanation:
Let the number of pizza made last week be represented by y.
From the question, we can form it into:
24% of y = 12
24/100 × y = 12
0.24 × y = 12
0.24y = 12
y = 12/0.24
y = 50
50 pizza were made last week.
From least to greatest it would be: 1.2, 1.23, 2.31, 3.2 I believe hope that helped
