Answer:
P(t) = 27000 - 4*t
Step-by-step explanation:
Over a period of time, if we know the population at certain time, and the rate of change of the population, we can express the function describing such population by means of these two parameters
Then:
P(t) = P₀ + 4*t
In our case
P(t) = 27000 - 4*t
Sign minus is for decreasing population t is in months, 4 is the rate of change and finally 27000 was population the first time Talulah counted the population
Answer:
Step-by-step explanation:
The circumference is either pi*d or 2 pi r
Use pi*d
3.14 * 14 = 43.96
Answer:
<em>0.009</em>

The solutions to the given system of equations are x = 4 and y = -9
<h3>Simultaneous linear equations</h3>
From the question, we are to determine the solutions to the given system of equations
The given system of equations are
-8x-4y=4 --------- (1)
-5x-y=-11 --------- (2)
Multiply equation (2) by 4
4 ×[-5x-y=-11 ]
-20x -4y = -44 -------- (3)
Now, subtract equation (3) from equation (1)
-8x -4y = 4 --------- (1)
-(-20x -4y = -44) -------- (3)
12x = 48
x = 48/12
x = 4
Substitute the value of x into equation (2)
-5x -y = -11
-5(4) -y = -11
-20 -y = -11
-y = -11 + 20
-y = 9
∴ y = -9
Hence, the solutions to the given system of equations are x = 4 and y = -9
