5blocks=6mins
18blocks=xmins.
18/5 × 6= 21.6 = 21mins
Unclear. Did you mean
<span>f(x)= [sqrt of x+3]
--------------------
(x+8)
or did you mean
3
</span><span>f(x)= [sqrt of x] + ----------
x+8
I will focus on the first possibility. The domain of sqrt(x+3) is [-3,infinity).
The domain of x+3
------- is "x is not equal to -8."
x+8
Then the overall domain would be simply [-3, infinity).

Answer:
x = 2000 cameras
Step-by-step explanation:
C(x) Total cost in producing x units
C- = C(x) /x Average cost of producing x units x > 0
Cannon Precision Instrument
C (x) Total monthly cost for producing x units of M1 cameras
is C(x) = 0.0025x² + 80x + 10000
Then average cost of producing x cameras M1 is
C-(x) = ( 0.0025x² + 80x + 10000) /x
C-(x) = 0.0025x + 80 + 10000/x
Taking derivatives on both sides of the equation
C-´(x) = 0.0025 - 10000/x²
Then
C-´(x) = 0
( 0.0025x² - 10000 ) / x² = 0
0.0025x² - 10000 = 0
x² = 10000 /0.0025 x² = 4000000
x = 2000 cameras
900,000 because that is where the value of 9 is placed in the number.
