Answer:

We can divide both sides by 20 and we got:

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

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

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:


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

We can divide both sides by 20 and we got:

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

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

So then the aproximate value of k is 0.30986 and rounded would be 0.31
x-4>15.5
x>15.5+4
x>19.5
i suppose the answer is D since it is the closest to ^.
Answer:
martina is 22 feet below sea level
Step-by-step explanation:
Marina goes down 20 feet
then rises 7 feet which is 20 - 7 = 13
then goes down 9 more feet which is 13 + 9 = 22 feet
20 - 7 + 9 =22
Martina is 22 feet below sea level.
One of the lines passes through points (0, 6) and (-4, 3). Hence the equation is given by:
(y - 6)/(x - 0) = (3 - 6)/(-4 - 0)
(y - 6)/x = -3/-4 = 3/4
4(y - 6) = 3x
4y - 24 = 3x
3x - 4y = -24
The other line passes through points (0, -3) and (1, 0). Hence the equation is given by:
(y - (-3))/(x - 0) = (0 - (-3))/(1 - 0)
(y + 3)/x = (0 + 3)/1
y + 3 = 3x
3x - y = 3
Therefore, the system of equations representing the graph is:
3x - 4y = -24
3x - y = 3
