Hello there!

A good first step is to fill the t=blanks with 2 and 4.

kobusy [5.1K]

Answer:

8000

Step-by-step explanation:

The function is given as:

P(n)=i \cdot 2^n

Where I=Initial Population

n=Number of Generations

If i=10^3, we want to determine the population of bacteria when n=3.

P(3)=10^{3} \cdot 2^3

=(10*2)^3 =20^3

=8000

There will be 8000 bacteria after 3 generations.

I need help with these questions
ASHA 777 [7]

Answer:

1. n = 13

2. x = -30

3. y > -18

4. n < -0.75

5. 101 t-shirts

Step-by-step explanation:

1. multiply both sides by 2, then add both sides by 2, making n = 13

2. divide both sides by -3, then subtract both sides by 5 making x = -30

3. divide both sides by -2, when dividing by a negative number, you need to switch the inequality sign to the other side

4. divide both sides by 4, then divide by -2(you need to switch the inequality sign to the other side), then add -8 and 2.5, then add 5.5 to both sides

5. the equation is 150 = 5x - 45. 45 is because they have already earned it, and 5x is how much each shirt will cost. The solution is then 101.

Hope this has a helped a little at least :P
