Step-by-step explanation:
In July, it was positive 29 degrees, but in December it was negative 29 degrees. When you have 29-29 you get 0. Hope that helped
Answer:
I think c over 5 i could be wrong
Answer:
Look for where both functions have the same y value. For example, when x = 3 in #7, both are 5. So the solution is (3,5).
Step-by-step explanation:
Each table has two functions. This forms a system of equations. A system of equations is essentially two conditions that must both be met to produce a solution. A solution can be found as where the two equations are equal. In the table, look for where both functions have the same y value for some x. This will be where the values are the same in the same row. This is the solution and is written as an (x,y) point.
7. When x = 3 both functions are 5. The solution is (3,5).
Answer:
Step-by-step explanation:
I'm fairly certain you have an error in your equation as the curve you suggests opens upward so has no maximum profit. Profit becomes positive on completion of the 7th unit. (curve crosses x axis at (6.056, 0))
I will GUESS that the equation should read
P(x) = - 2x² + 120x – 800
Maximum will occur when the derivative is zero (zero slope)
P(x) = -2x² + 120x – 800
P'(x) = -4x + 120
0 = -4x + 120
x = 30
P(30) = -2(30)² + 120(30) – 800
P(30) = $1000
