Answer:
a) Profit P = -70 that is a loss
b) break even time t = 15 units
Step-by-step explanation: Given that the equation
P(t) = t^2 − 13t − 30
Where P represents his profit (money made) over time t
a. Find P(5). That is, the profit made when time t = 5
P(5) = 5^2 - 13(5) - 30
P(5) = 25 - 65 - 30
P(5) = -70
This means that Mr bean is making a loss of 70 dollars as at time t of the day equal to 5
Mr. Bean will break even when his profit equals zero.
P(t) = t^2 − 13t − 30
P(0) = t^2 − 13t − 30 = 0
t^2 − 13t − 30 = 0
Factorizing the above equation will give us
(t -15)(t + 3)
t = 15 or -3
Since time t can't be negative, the time of break even will be 15 units
Y=6 looks good to me hope you get an A
Triangle Area Formula:
0.5 * Base * Height
SO,
0.5 * 10 * Height = 45.5
5 * Height = 45.5
Height = 9.1
Answer:
In the ATTACHMENT
Step-by-step explanation:
For the first one, you can plug in multiple numbers of any kind for 
and start to form you line.
For the second one, know that the 
line is always horizontal. Find -3 on the plot that would be on the 
and put that horizontal line on it.
