Answer:
the answer you have chosen is right.
Step-by-step explanation:
A rational number can be written as a simplified fraction, and or is a recurring or finite decimal. That is the only number that can be properly written according to the rules I just stated.
Hey I’m sorry but I do not know the answer.
C(x) = 400 + 20x - 0.2x²
c(30) = 400 + 20(30) - 0.2(30)²
= 400 + 600 - 0.2(900)
= 1000 - 180
= 820
It costs $820 when 30 radios are produced.
Marginal cost is how much it would cost to make one MORE of the same product so now we find how much it costs to produce 31 radios and compare the two.
c(31) = 400 + 20(31) - 0.2(31)²
= 400 + 620 - 0.2(961)
= 1020 - 192.2
= 827.8 or ≈828.
Now we find the difference which means we subtract the two.
828 - 820 = 8.
Your marginal cost is $8.
To compare we can also do 29 radios.
c(29) = 400 + 20(29) - 0.2(29)² = 811.8 or ≈812
820 - 812 = 8.
If n = number of hours and the equation is 174 + 58n then the answer is 3 hours
174 = 58n
÷ 58
3 = n
Answer: 58 Days
Step-by-step explanation:
Because if you divide 4,325 from 75 miles you get 57.6666 and so on so when you round it you get 58 days
