Answer:
The expression that represents the population of elk is: . 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 , then after the first year the population will be:
While on the second year, it'll be:
On the third year:
And so on, therefore the expression that describes the population of elk as the years passes is:
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.
The population will reach 1,458 elk in 6 years.
Answer:
B.
Step-by-step explanation:
It is very possible.
Make the value of apple x and the value of orange y.
5x + 4y = 10
5x + 5y = 11
-y = -1
y = 1
x = 1.2
Now just match them up.
Yes; They should charge $1.20 for and apple and $1.00 for an orange.
Answer:
The answer is C! horrizontal shift right pi/2 units.
Step-by-step explanation:
I just took the test and got it right!
We can write the factored form of the equation because we know the roots are 3 and 5.
Therefore the factored form is (x-3)(x-5) Remember it is -3 and -5 because of the Zero Product Property.
From here, we can foil. (x-3)(x-5)=x^2-5x-3x+15
That simplifies to x^2-8x+15, which is choice B
