What is the volume of the figure below if a = 3.9 units, b = 5.7 units, and c = 3 units?

9966 [12]

3.9+3.9 = 7.8

7.8 * 3.9 * 3 = 91.26

5.7 * 3.9 * 3 = 66.69

66.69 + 91.26 = 157.95

Given the data shown below, which of the following is the best prediction for

Soloha48 [4]

Answer:

The best prediction for the number of years it will take for the population to reach 200,000 is 9.41

Step-by-step explanation:

Year Population

1 11,920

2 16,800

3 23,300

4 33,000

5 45,750

6 64,000

$y_1 =A _0 e ^{kt _1}\\y_2 = A_0 e^{k t_2}\\(t_1,y_1)=(1,11920)\\(t_2,y_2)=(2,16800)$

Substitute the values

$11920=A _0 e ^{k} ---1\\16800 = A_0 e^{2k} ---2$

Divide 1 and 2

$\frac{11920}{16800}=\frac{e^k}{e^{2k}}\\\frac{11920}{16800}=e^{k-2k}\\ln(\frac{11920}{16800})=-k\\k=-1 ln(\frac{11920}{16800})\\k=0.3432\\A_0=y_1 e^{-k t_1}\\A_0=11920 e^{-0.3432}\\A_0=8457.5238$

The exponential function that passes through the points (1, 11920) and (2, 16800) is $y=8457.5238 e^{0.3432t}$

Now we are supposed to find the best prediction for the number of years it will take for the population to reach 200,000

$200000=8457.5238 e^{0.3432t}$

$\frac{200000}{8457.5238}=e^{0.3432t}$

$ln(\frac{200000}{8457.5238})=0.3432t$

t = 9.41

Hence the best prediction for the number of years it will take for the population to reach 200,000 is 9.41
