Answer:
The egg hits the ground after 2.5 seconds.
Step-by-step explanation:
Height of the egg:
The height of the egg after t seconds is given by:
After how many seconds does the egg hit the ground?
This is t for which . So
The egg hits the ground after 2.5 seconds.
Answer:
( A -c) /B =t
Step-by-step explanation:
A=Bt+c
Subtract c from each side
A-c=Bt+c-c
A -c = Bt
Divide each side by B
( A -c) /B = Bt/B
( A -c) /B =t
Answer:
$1,200
Step-by-step explanation:
Data provided in the question:
R'(x)= -0.1x + 40
now,
Revenue function = ∫R'(x)= ∫(-0.1x + 40)
or
R(x) =
here, c is the integration constant
also,
at x = 0, Revenue R = 0
thus,
0 =
or
c = 0
therefore,
we get the revenue function as;
R(x) =
a) For x = 230 units
R(230) =
or
R(230) = - 2645 + 9200 = $6,555
b) R(330) =
or
R(330) = -5445 + 13,200 = $7,755
Hence,
the addition evenue realized when the production (and sales) level is increased from 230 to 330 units
= $7,755 - $6,555
= $1,200
Answer:
27
Step-by-step explanation:
You add 63 and 90 (90 being the right angle) and then subtract that from 180 which is the sum of all three angles and you get 27.
