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

I don't know but plz make me brainliest
The new length of the string will be 16 1/4 feet. Then the correct option is B.
<h3>What is the length?</h3>
It is the measure of distance between the two points and is known as length. The length is measured in meters generally.
Ed needed to extend the string on his kite. The current string was seven and three-fourths feet that is (7 3/4).
The mixed fraction number is coverted into a decimal number.
7 3/4 = 7.75 feet
He cut a piece of string that measured 8.5 feet and added it to the existing string.
Then the new length of the string will be
L = 7.75 + 8.5
L = 16.25
L = 16 1/4 feet
The new length of the string will be 16 1/4 feet. Then the correct option is B.

Answer:
-1
i do not remember how to solve this but i just answered a question that had this problem in it on my algebra test and that is the right answer
lol sommet i would do lol but i didnt ahaha
Answer:
follow steps below --------------------------------------(down arrow)
Step-by-step explanation:
to work out the surface area you would do
base times height
length times width
height times width then add all together
