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:
x=55.5
Step-by-step explanation:
First add 94 and 17 to get 111
Then subtract 111 from 180 and get 69 for the third angle on the triangle on the right.
69 is a vertical angle so the other angle is 69 as well.
180-69 is 111 and 111/2 is 55.5 because x is equal to the other angle on the triangle.

Answer:
The graph of y=log(x)+4 is the graph of y=log(x) translated 4 units up.
Step-by-step explanation:
The translation ...
y = log(x -h) +k
translates the log function right h units and up k units.
The only description matching the equation is ...
The graph of y = log(x)+4 is the graph of y = log(x) translated 4 units up.
