Sum of cubes

Step-by-step explanation:

Derek found a function that approximately models the population of iguanas in a reptile garden, where x represents the number of years since the iguanas were introduced into the garden.i(x) = 12(1.9)^x


Rewrite this function in a form that reveals the monthly growth rate of the population of iguanas in the garden. Round the growth factor to the nearest thousandth.

Answers

Answer:

i(x)=12 * (1+(0.9)/(12))^(12x) and growth rate factor is 0.075

Step-by-step explanation:

The function that models the population of iguanas in a reptile garden is given by i(x)=12 * (1.9)^(x), where x is the number of years.

Since, i(x)=12 * (1.9)^(x)

i.e. i(x)=12 * (1+0.9)^(x).

Therefore, the monthly growth rate function becomes,

i.e. i(x)=12 * (1+(0.9)/(12))^(x * 12).

i.e. i(x)=12 * (1+(0.9)/(12))^(12x).

Hence, the monthly growth rate is i.e. i(x)=12 * (1+(0.9)/(12))^(12x).

Also, the growth factor is given by (0.9)/(12) = 0.075.

Thus, the growth factor to nearest thousandth place is 0.075.

A. 1/2
B. 1/5
C. 1/10
D. 1/15

Answers

A. The number of fabric-pattern-color combinations is 4 * 13 * 9 = 468

B. P(1st choice) = no of novels / total books = 3/6 = 1/2
    P(2nd choice) = no of remaining novels/ total remaining books = 2/5
    P(both novels) = 1/2 * 2/5 = 1/5          (without replacement assumed)

C. P(1st choice) = no of biographies / total books = 2/6 = 1/3
    P(2nd choice) = no of remaining biographies/ total remaining books =        1/5
    P(both biographies) = 1/3 * 1/5 = 1/15          (without replacement                assumed)

D. P(1st choice) = no of history books / total books = 1/6
    P(2nd choice) = no of novels/ total remaining books = 3/5
    P(a history, then a novel) = 1/6 * 3/5 = 1/10          (without replacement assumed)

Credit cards and charge cards differ in two important ways. One is the method of payment. What is the other difference?A. You can get a credit card from your bank but not a charge card.
B. You have to pay interest on charge cards but not on credit cards.
C. You have to pay interest on credit cards but not on charge cards.

Answers

The correct answer is:

C) You have to pay interest on credit cards but not on charge cards.

Explanation:

A charge card is a card in which you are required to pay the balance in full every month. Because of this, there is no charge that accrues from month to month, so there is nothing to charge interest on.

I think the correct answer from the choices listed above is option C. Credit cards and charge cards differ in many ways. One of which is the method of payment where you have to pay interest on credit cards but not on charge cards. Hope this answers the question.
