Answer:
y = 75x + 125
She plans on spending 500$
Answer:
2y + 367
Step-by-step explanation:
8(2y - 1) - 14y + 375
16y - 8 - 14y + 375
2y + 367
Answer:
(dP/dt) = 0.00078P (2000 - P)
Step-by-step explanation:
A logistic differential equation is given as
(dy/dx) = ay(b - y)
where a and b are constants.
So, for this question,
(dP/dt) = aP(b - P)
b is the total possible value that P can attain and for this question, b = 2000 (the total number of people at the party)
Taking the time at 9pm to be t = 0,
At t = 0,
P(0) = 400 and (dP/dt) = 500 at t = 0
Inserting these into the differential equation
(dP/dt) = aP(b - P)
500 = 400a(2000 - 400)
400a = (500/1600)
400a = 0.3125
a = (0.3125/400)
a = 0.00078125
(dP/dt) = aP(b - P)
Inserting the constants
(dP/dt) = 0.00078125P (2000 - P)
Hope this Helps!!!

Step-by-step explanation:
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- A pound of fertilizer covers 37 square feet of lawn.
- Vivian has 9110.1 square feet of lawn.
2. Therefore, to calculate the pounds of fertilizer needed, you must multiply the area of lawn that she has by one pound and divide this by the area convered by a pound:
Then, the answer is: 246.2 pounds.
