<1 = 120/2 = 60
answer
60 <span>degrees</span>
2x + 6y = 5
x + 3y = 2 .....multiply by -2
-----------------
2x + 6y = 5
-2x - 6y = - 4 ...(result of multiplying by -2)
----------------add
0 = 1 (incorrect).......no solutions because the lines are parallel.
little tip :
if ur system of equations comes out where it is not equal....like 4 = 5, or 6 = 7...then there is no solutions.
if ur system of equations comes out where it is equal...like 5 = 5 or 8 = 8, then there is infinite solutions
if ur system of equations comes out where a variable = a number....like x = 2 or y = 5.....then there is one solution
Answer:
a) $2,641,885.90
b) $264,188.59
Step-by-step explanation:
The total profit is the integral of the marginal profit. The marginal profit is the difference between marginal revenue and marginal cost.
a) To find the total profit for the first 10 days, we evaluate P(10):
P(10) = 120(e^10 -1) -120(10) +0.3(10^2) = 120(22026.4658 -1) -1200 +30
P(10) = 2,641,885.90 . . . . rounded to cents
The total profit from day 0 to day 10 is $2,641,885.90.
__
b) The average daily profit is the total profit divided by the number of days:
average profit per day = P(10)/10 = $264,188.59
The average daily profit for the first 10 days is $264,188.59.
Step-by-step explanation:
|2b - 9| = |b - 6|
|2b - b| = |-6 + 9|
|b| = |3|
b = 3
