Answer:
Step-by-step explanation:
We can write this rate as an ordinary differential equation.
Where a is proportional constant, P the population variable, and t the time.
Integrating each side of the equation.
To find C we need to use the initial condiction, it means evaluae P at t=0.
Now, we use the sentence the population has doubled in 5 years.
We can find "a" in this condition.
Finally, let's find how long will it take to triple.
I hope it helps you!
The answer is negative three
Answer:
4322.64 ft^2
Step-by-step explanation:
Diameter:
Area of circle: - r = radius
Area of rectangle: - l = length, w = width
The area of the family's backyard is 110 × 50 = 5500 feet. Now, let's find the area of the circular swimming pool.
Next, we find the area of the concrete walkway.
After that, we add the area of the circular pool and walkway.
Lastly, subtract 1177.36 from 5500.
Therefore, the answer is 4322.64.

Answer:
Blouse = $13.00
Jeans = $25.50
Step-by-step explanation:
x = blouse
y = jeans
x + y = 38.5
y = x + 12.5
Use substitution:
x + x + 12.5 = 38.5
2x = 26
x = 13
Blouse = $13.00
Jeans = $25.50
