Answer:
c = 4 A
Step-by-step explanation:
The given function P(c) = - 15 c (c-8) is actually quadratic function:
P(c) = - 15c² + 120c or parabola
The standard form of a quadratic function is:
y = ax² + bx + c
For which x is the maximum of the parabola we can find with this formula
x = - b/2a
in this case a = -15 and b = 120 and input variable is current c
c = - 120/(2 · (-15)) = - 120/ (-30) = 4 A
c = 4 A
God with you!!!
Answer:
A
Step-by-step explanation:
To start off, you know 18 hours= 720
So you could automatically get rid of B and D since 19 and 17 are not 18.
After that, you have it down to A and C. The way you would find how much she charges for one hour is dividing 720 by 18. When you do that it means you are divding 720$ into 18 different groups each group representing an hour. When you divide 720 by 18 you should get 40. So every hour she makes 40 dollars. 40x 2 hours is 80. I hope I helped you!
Answer:
a=14
Step-by-step explanation:
-a+28=14
So -a=-14
so a=14
Answer:
the graph will start at y1 and go down 1 and right 2 for every point.
Step-by-step explanation: since the x is negative you know that the graph is going to be negative so from left to right it will be going from top to bottom. next you look at the 1/2 which just states that every point on that line will will be 1 down and two right from the previous point. now you look at the +1 which just says that the graph will cross the y axis a 1.
1. The withdrawals adds up to 291+99+150+12= 552
500-552= -52
2. The bus pass which cost $150.
3.1000-552= $448 left
4.1000-552-300-150=$-2 left. Withdrawal had happened.
