Answer:
(x-7) (x+1)
Step-by-step explanation:
x^2 - 6x - 7
What two numbers multiply to -7 and add to -6
-7*1 = -7
-7+1 = -6
(x-7) (x+1)
Answer: SORRY I READ THE QUESTION WRONG
Food items
Step-by-step explanation:
Proper nouns should be capitalized. Food items is NOT a proper noun
Identify and sum up the x^2 terms: Result: 3x^2
Next, ident. and sum up the x terms: Result: (1/3 + 2) = (7/3)x
Last, ident. and sum up the const. terms: Result: -2 - 6 = -8
The sum of these two functions is 3x^2 + (7/3)x - 8.
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.
