Answer:
2/3
Step-by-step explanation:
Answer:
(a) dy/dt = 68 - 3.72t
(b) 64.28m/s
Step-by-step explanation:
Given y = 68t - 1.86t²
Average Speed is rate of chance of distance with respect to time. Written as dy/dt
To obtain dy/dt, we differentiate y with respect to t, doing that, we have
dy/dt = 68 - 2(1.86)t
= 68 - 3.72t
(a) dy/dt = 68 - 3.72t
(b) To estimate the speed when t = 1, we substitute t = 1 in dy/dt .
dy/dt at t = 1 is
68 - 3.72(1)
= 68 - 3.72
= 64.28
The speed at t = 1 is 64.28m/s
Answer:
2 * sqrt(61)
Step-by-step explanation:
a = 10
b = 12
c = ?
c^2 = a^2 + b^2
c^2 = 10^2 + 12^2
c^2 = 100 + 144
c^2 = 244
c^2 = 4 * 61
sqrt(c^2) = sqrt(4) * sqrt(61)
c = 2 * sqrt(61)
