Answer:
<u>73</u>
Step-by-step explanation:
2+2+3+65+1
=4+3+65+1
=7+65+1
=72+1
=73
Subtract 43 to both sides so now your equation is x^2-36 and that factoring of that is (x-6)(x+6) so X=6 and X=-6
Answer:
The correct answers are a) $652.5; b) $212.375; c) $13.05; d) R(51) = $689.52, R(52) = $732.68, R(53) = $775.125.
Step-by-step explanation:
Revenue function of Pierce Manufacturing from the sale of x lawns is given by R(x) = 0.005 + 0.01 + 0.05x.
Daily, Pierce Manufacturing is selling 50 lawn chairs.
a) Current daily revenue, i.e. x is 50 = 625 + 25 + 2.5 = $ 652.5.
b) Increase in revenue by selling 5 more chairs = R(55) - R(50) = $ (864.875 - 652.50) = $ 212.375.
c) Marginal Revenue function is given by dividing the revenue function by quantity. Therefore MR(x) = 0.005 + 0.01x + 0.05.
Value MR(50) = 12.5 + 0.5 + 0.05 = $ 13.05.
d) The value of R(51) = MR(51) × 51 = $ (13.52 × 51) = $ 689.52.
The value of R(52) = MR(52) × 52 = $ (14.09 × 52) = $ 732.68.
The value of R(53) = MR(53) × 53 = $ (14.625 × 53) = $ 775.125.
Answer:
20%
Step-by-step explanation:
We can solve this with the rule of three.
If 100% represents 10 records, what percentage would be for 12 records?
So, if we subtract , it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.
