Answer 2
Answer:

Final answer:

The population of insects is doubling each month. To figure out the population after 7 months, we can use the formula for exponential growth, 2^n, where n is the number of months. Using this formula, after 7 months, there will be 12,800 insects.

Explanation:

The population of insects is doubling each month, so the insect population is growing exponentially. To calculate the population after 7 months, you can use the formula for exponential growth, which is 2^n, where n is equal to the number of time periods, in this case, months.

After 1 month, the population is 100 * 2 = 200. After 2 months, the population is 200 * 2 = 400, and so on. After 7 months, we can calculate as follows:

100 * 2^7 = 100 * 128 = 12800 insects. So, after 7 months, there will be 12,800 insects if the population doubles each month.

What number will make this expression a perfect square trinomial? Show your work.x² - 6x + __

Answers

Answer:

+ 9

Step-by-step explanation:

given

x² - 6x

to make a perfect square use the method of completing the square

add ( half the coefficient of the x- term)² to x² - 6x

x² - 6x

= x² + 2(- 3)x + (- 3)²

= x² - 6x + 9

so

x² - 6x + 9 = (x - 3)² ← a perfect square

Heidi is saving for a new bike. She has already saved $57. If Heidi earns$9 per hour babysitting, how many hours does she need to babysit to
afford the bike which costs $129? Write and solve a linear function to solve.
Type your answer as an integer.

Answers

Heidi needs to babysit for 8 hours to afford the new bike.

What is the linear equation?

The linear equation is the algebraic form of equation whose variable has the exponent of one. It is the combination of two variables and a constant value present in them.

For the given situation,

Heidi's savings = $57

Amount for babysitting per hour = $9

Total cost of the bike = $129

Let us consider 'x' for hours she needs to babysit.

This can be represented as linear equation as

57 +9h=129

9h=129-57

9h=72

h=8

Hence we can conclude that Heidi needs to babysit for 8 hours to afford the new bike.
