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) isy=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

If $360 is invested at an interest rate of 13% per year and is compounded continuously, how much will the investment be worth in
Vlada [557]

Answer:

  none of the above; $531.71

Step-by-step explanation:

Fill in the given numbers and do the arithmetic.

  A = $360·e^(0.13·3) = $360·e^0.39 ≈ $360·1.1.47698

  A ≈ $531.71

___

None of the offered choices is correct. Have your teacher show you how this problem is worked.

_____

Answer choice c) is approximately correct for an interest rate of 16%. The correct value would be $581.79.

Find the value of "r" so that the line through (2,-3) and (-4,r) has a slope of -1/2
trapecia [35]
Hi there! The formula for finding slope is y2 - y1/ x2 - x1. -4 represents x2, and 2 represents x1. -4 - 2 is -6. If you think about it, 3/-6 makes -1/2. -3 is y1, so we will be adding, because adding a negative number actually means adding. 0 - (-3) gives us 3. There. The value of r is 0.
