Queston 4: The range of the relation is : (-2,4)

Question 5: the domain of the relation is:
{2, 2.1, 5.1, 5.5, 6}

Question 6: The relation is not a function because it two of the x value have the same y values. Therefore it is not a function as it does not pass the vertical line test.
(-4, 0) and (-3, 0) both have 0 for the y coordinate. A function can’t have this.

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 slope given on a graph?

oee [108]

You use rise over run. So you first count the rise( how many upwards is the point) then count the run( how many to the right or left is the point)

What is the volume of a square pyramid that has a base length of 5 inches and a height of 9 inches?

PtichkaEL [24]

Well since the for formula for these are b × h. We are gonna do...

5 × 9 which equals 45. So your answer is 45 cubic inches

hope this helps!
