two bird populations were studied and formulas were developed for each populations growth. the populations p1 and p2 are given b

STatiana [176]

Answer:

$20 e^{k*10} = 60 e^{0.2*10}$

We can divide both sides by 20 and we got:

$e^{10k}= 3 e^{2}$

Now we can appply natural log on both sides and we got:

$10 k = ln(3e^2)$

Now we can divide both sides of the equation by 10 and we got:

$k = \frac{ln(3e^2)}{10}= 0.30986$

So then the aproximate value of k is 0.30986 and rounded would be 0.31

Step-by-step explanation:

We have the following two expression:

$p_1 = 20 e^{kt}$

$p_2 = 60 e^{0.2t}$

We know that the two populations were equal 10 years after the start of the study, so then we can create the following equation:

$20 e^{k*10} = 60 e^{0.2*10}$

We can divide both sides by 20 and we got:

$e^{10k}= 3 e^{2}$

Now we can appply natural log on both sides and we got:

$10 k = ln(3e^2)$

Now we can divide both sides of the equation by 10 and we got:

$k = \frac{ln(3e^2)}{10}= 0.30986$

So then the aproximate value of k is 0.30986 and rounded would be 0.31

How do you find the intersection points given 2 or more equations in a ti-84 calculator?

mel-nik [20]

You click on the button that says "Y=" then you type in the equations into y=1 , y=2 and so forth. click graph and the lines will appear. use the up, down, left, and right buttons to move the cursor and find the exact point.

If the standard deviation of the data values in a sample is 17, what is the variance of the data values

Bess [88]

Std dev = sqrt of variance

hence variance would be 17^2= 289

A circle has a radius of 10 inches. Find the approximate length of the arc intersected by a central angle of 2π/3

Aleksandr-060686 [28]

Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Radius of circle = 10 inches

Central angle is given by

$\frac{2\pi }{3}$

As we know the formula for " Length of an arc " :

Length of arc is given by

$l=r\theta\\\\l=10\times \frac{2\pi}{3}\\\\l=10\times \frac{2}{3}\times \frac{22}{7}\\\\l=20.95\ inches$

Hence, length of an arc is 20.95 inches.

Hence, Option 'C' is correct.
