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.
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.

f(x) = 102; 9(1) = 1 + 3
Answer:
9=4
Step-by-step explanation:
9(1)= 1+3
9(1)=9
1+3=4
9:4
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
Answer:
A.
Step-by-step explanation:
The answer is A.
afford the bike which costs $129? Write and solve a linear function to solve.
Type your answer as an integer.
Heidi needs to babysit for 8 hours to afford the new bike.
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
⇒
⇒
⇒
Hence we can conclude that Heidi needs to babysit for 8 hours to afford the new bike.
