Your friend has owned a dog for 9 years. This is one year less than twice as long as he has owned a cat. How long has your friend owned a cat?

Answers

Answer 1

Answer:

Answer:

He has owned a cat for 5 years.

Step-by-step explanation:

He has owned a dog for 9 years, and this time is one year less than twice as long as he has owned a cat.

So, we can express this like:

$9=2x-1$

Solving for $x$ :

$9+1=2x\nx=(10)/(2)=5$

Therefore, he has owned a cat for 5 years.

Answer 2

Answer: your friend has owned a cat for 17 years, because 9 times 2 subtracted by 1 equals 17

Suppose that an insect population’s density, in thousands per acre, during year n, can be modeled by the recursive formula: a1 = 8 an = 2.9an – 1 – 0.2(an – 1)^2 Which of the following describes what is happening to the insect population for the first five years?

Answers

Answer:

The population alternates between increasing and decreasing

Step-by-step explanation:

The options of the question are

A) The population density decreases each year.

B) The population density increases each year.

C) The population density remains constant.

D) The population alternates between increasing and decreasing

we have

$a_n=2.9(a_n_-_1)-0.2(a_n_-_1)^2$

$a_1=8$

Find the value of $a_2$

For n=2

$a_2=2.9(a_1)-0.2(a_1)^2$

$a_2=2.9(8)-0.2(8)^2=10.4$

Find the value of $a_3$

For n=3

$a_3=2.9(a_2)-0.2(a_2)^2$

$a_3=2.9(10.4)-0.2(10.4)^2=8.528$

For n=4

$a_4=2.9(a_3)-0.2(a_3)^2$

$a_4=2.9(8.528)-0.2(8.528)^2=10.1858$

For n=5

$a_5=2.9(a_4)-0.2(a_4)^2$

$a_5=2.9(10.1858)-0.2(10.1858)^2=8.7887$

therefore

The population alternates between increasing and decreasing

Answer:

D.) The population alternates between increasing and decreasing.

Emily wants to have her Photo album printed. The printing company charges $24.50for the first book, and then a flat rate for each additional book. Emily pays $48.50 for 4
books. How much is the flat rate after the first book is purchased?

Answers

Answer: $8 flat rate

Step-by-step explanation: First subtract 24.50 from 48.50 to find the amount that was charged for the 3 additional books.

48.50 - 24.50 = 24

So the remaining 3 books costed a total of $24

Next, we need to divide 24 by 3 to determine how much each additional book costs.

24/3 = 8

So, the flat rate after the first book is purchased is $8 per additional book.
