A biologist is studying the elk population in a county park. She starts with only 2 elk and observes that the number of elk trip

DochEvi [55]

Answer:

The expression that represents the population of elk is: $\text{elk}(t) = 2*3^t$ . It'll take 6 years for the population to reach 1,458 individuals.

Step-by-step explanation:

Since the number of elks triples every year and starts at $\text{elk}(0) = 2$ , then after the first year the population will be:

$\text{elk}(1) = \text{elk}(0)*3 = 2*3$

While on the second year, it'll be:

$\text{elk}(2) = \text{elk}(1)*3 = 2*3*3 = 2*3^2$

On the third year:

$\text{elk}(3) = \text{elk}(2)*3 = 2*3^2*3 = 2*3^3$

And so on, therefore the expression that describes the population of elk as the years passes is:

$\text{elk}(t) = 2*3^t$

If we want to know the number of years until the population reach 1,458 elk, we need to apply this value to the left side of the equation and solve for t.

$1458 = 2*3^t\\3^t = \frac{1458}{2}\\3^t = 729\\ln(3^t) = ln(729)\\t*ln(3) = ln(729)\\t = \frac{ln(729)}{ln(3)} = 6$

The population will reach 1,458 elk in 6 years.

Someone please help and correct me if im wrong and explain all of it if I am please!!:) 25pts

*Yes, B, C, and D are correct. -15, -10.5, and -7.5 are solutions to x<-7*........................... ...................................................................................................................................... *8y – 24 > –16............................................................................................................. 8y>8 ADD 24 to both sides ....................................................................................... y>1 so C. divide both sides by 8................................................................................. It is not A because the opposite of subtracting 24 is adding 24. So you add 24 to both sides to undo the subtraction. -16+24=8 Then you divide both sides by 8, which gives you y>1. I think you probably subtracted 24 from -16 instead of adding it.*......................................... ...................................................................................................................................... *I'm not sure what to make of the third one, is that a number line or...?*............................... ...................................................................................................................................... *- t/5 ≥15 ........................................................................................................................ -t ≥ 75 MULTIPLY both sides by 5.................................................................................... t ≤ -75 divide both sides by -1, and flip the sign, because when dividing an inequality by a negative number you must flip the sign.............................................................................. So A would be correct. .................................................................................................... I believe if you divided the 15 by 5 and didn't flip the sign you would get D.*......................... Also, sorry, my enter key isn't working right, so it's all scrunched together.
