Answer:

Domain: [2, ∞)

Step-by-step explanation:

Domain is the set of x-values that can be inputted into function f(x).

We see that we cannot take the 4th root of a negative number, so under the square root, the entire thing can't be negative. This means that the x-value cannot be lower than 2, but can be 2 itself:

[2, ∞)

Tavius wants to invest $2,500. Which option will earn him the best value?

Step2247 [10]

Tavius would earn his best value if he invests in a three-year certificate of deposit with a nominal interest rate of 4 percent.

Tavius would invest in the option that yields the highest interest. This is the best value. In order to determine which option is the best, the interest rate of each option has to be determined.

Interest rate of the first option

Interest earned = amount invested x time x interest rate

$2500 x 0.03 x 2 = $150

Interest rate of the second option

Interest earned = amount invested x time x interest rate

$2500 x 0.03 x 1 = $75

Interest rate of the third option

Interest earned = amount invested x time x interest rate

$2500 x 0.04 x 3 = $300

Interest rate of the fourth option

FV = P x (1 + r) n

$2500 x (1.03) = $75

How would I do this problem?

kenny6666 [7]

If it's a geometric sequence then:

$a_1=27;\ a_2=27\\\\r=\dfrac{a_2}{a_1}\to r=\dfrac{27}{36}=\dfrac{3}{4}=0.75\\\\a_{n+1}=a_nr\\\\a_3=27\cdot0.75=20.25\ CORRECT$

We calculate the fourth and fifth term of the sequence:

$a_4=a_3r\to a_4=20.25\cdot0.75=15.1875\\\\a_5=a_4r\to a_5=15.1875\cdot0.75=11.390625$

Answer:

In year 4 15.1875 animals.

In year 5 11.390625 animals.
