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
The answer is A.
hope this helps!

Answer:
27 mm
Step-by-step explanation:
The perimeter of the triangle is the sum of all sides lengths. In given triangle
first side has the length of 11 mm, the second side has the length of 35 mm.
If the perimeter is 73 mm, then
I’m pretty sure the answer is B because
8X- 4Y = -16 and it shows that in the equation of number B and if I’m wrong please correct me
