What is the formula of exponential growth?"[tex]f(x)=ab^x[/tex],
where a is the initial value
b is the growth rate
x is time. "
For given question,
Suppose the function for the population growth is,
[tex]A(t)=A_0\times b^t[/tex]
A colony of insects doubles every day.
⇒ b = 2
The colony has 5 insects today.
⇒ [tex]A_0=5[/tex]
So, the exponential growth function would be,
[tex]A(t)=5\times 2^t[/tex] ...........(1)
We need to find the number of insects after 20 days,
From equation (1),
[tex]\Rightarrow A(20)=5\times 2^{20}\\\\\Rightarrow A(20)=5\times 1048576\\\\\Rightarrow A(20)=5242880[/tex]
Therefore, 5242880 insects would be present in 20 days.

Step-by-step explanation:
Step 1: Define equation
4 - 3p = 22
Step 2: Solve for p
Subtract 4 on both sides: -3p = 18Divide -3 on both sides: p = -6Step 3: Check
Plug in p into the original equation to verify it's a solution.
Substitute in p: 4 - 3(-6) = 22Multiply: 4 + 18 = 22Add: 22 = 22Here we see that 22 does indeed equal 22.
∴ p = -6 is a solution to the equation.

Help!! How do I do 1 and 2
Answers
Answer:
1. The mode. 2. See below
Step-by-step explanation:
1. To find the mean, you need to add all the numbers up. So, add 24, 27, 31, 32, 36, 36, 36, 39, 40, 58, 58, and 59 to get 503. Then, you need to divide 503 by how many numbers there are, which in this case is 12. So, 503/12 ≈ 42. This number is rounded because it is a repeating decimal. The median is the middle number of the set when it is lined up in order of lowest to highest. In this case, we would need to add up the two middle numbers, 36 + 36, and divide by 2 to find the median. This is 54. The mode is the number that shows up most often. Here, this is 36. In this case, the mode best represents the data because the other two numbers are a bit too high.
2. Add 90 + 90 + 91 + 93 + 99 + 102 + 102 + 105 + 120 + 123 + 128 + 128 + 129 = 1523. Divide by 13 to get approximately 117, which is rounded because it is an ongoing decimal. The median is 102. In this case, we have 3 modes because more than one number occurs two times, so the modes are 90, 102, and 128. This one I'm unsure on since I haven't done this stuff in a while, and that's up to you. The modes give a pretty accurate representation of the range of the data, but then again so does the median and mean. It's up to you and what you've been taught.
