How do you do this question?
Alex Ar [27]

Step-by-step explanation:

(a) dP/dt = kP (1 − P/L)

L is the carrying capacity (20 billion = 20,000 million).

Since P₀ is small compared to L, we can approximate the initial rate as:

(dP/dt)₀ ≈ kP₀

Using the maximum birth rate and death rate, the initial growth rate is 40 mil/year − 20 mil/year = 20 mil/year.

20 = k (6,100)

k = 1/305

dP/dt = 1/305 P (1 − (P/20,000))

(b) P(t) = 20,000 / (1 + Ce^(-t/305))

6,100 = 20,000 / (1 + C)

C = 2.279

P(t) = 20,000 / (1 + 2.279e^(-t/305))

P(10) = 20,000 / (1 + 2.279e^(-10/305))

P(10) = 6240 million

P(10) = 6.24 billion

This is less than the actual population of 6.9 billion.

(c) P(100) = 20,000 / (1 + 2.279e^(-100/305))

P(100) = 7570 million = 7.57 billion

P(600) = 20,000 / (1 + 2.279e^(-600/305))

P(600) = 15170 million = 15.17 billion

How do you write an equation for the sum of three consecutive numbers equals 384?
emmasim [6.3K]
Let x be the smallest number.
x+(x+1)+(x+2)=384
3x+3=384
3x=381
x=127
The three consecutive numbers are 127, 128 and 129.

Hope my answer helped u :)

Can someone please answer. There is only one problem. There's a picture too. Thank you!

The answer is 14137.17 because to find the volume of the sphere, the equation is 4/3 times pi times the radius cubed.

Answer:

Step-by-step explanation:

14.)

2x+x+90=189

3x=90

x=30

lets find y:

2y=x

2y=30

y=15

lets find z:

2y+z=180

30+z=180

z=150
