100 - 5d + 10d = 130
5 x 20 = 100
5 x -d = -5d
The answer should be 9.
After you solve what's in the parentheses, you solve the problem starting from left to right.
6÷2(1+2)
6÷2(3)
3(3)
9
Answer:
49
Step-by-step explanation:
The cost function is the sum of the costs as a function of the number of bins made.
C(x) = 4x + 18424
The profit function is the difference between the revenue and the cost functions.
P(x) = R(x) - C(x)
P(x) = -2x^2 + 478x - (4x + 18424)
P(x) = -2x^2 + 474x - 18424
The smallest break-even point is the smallest value of x at which profit is zero. Zero profit means there is no gain and no loss.
P(x) = -2x^2 + 474x - 18424 = 0
x^2 - 237x + 9212 = 0
9212 = 2^2 * 7^2 * 47
(x - 188)(x - 49) = 0
x - 188 = 0 or x - 49 = 0
x = 188 or x = 49
Answer: 49
Answer:
(D) f(x+1)=2f(x)
Step-by-step explanation:
The sequence is:
Now,
On continuous calculation, we would discover that the next term is gotten from the preceding term by multiplying it by 2.
Therefore for term f(x), the next term f(x+1) is:
f(x+1)=2f(x)
Answer:
x= 20
Step-by-step explanation:
24/18= 1.33
1.33*15= 20
