I have 0 idea but I need help with some questions that I have
It will take 8 seconds for all of the dominoes to fall over.
This will be an exponential function. To find the growth rate, we can write out the terms of the sequence that goes along with it: 10, 20, 40, ...
"Growth rate" is the same as percent of increase or decrease. We find the amount of increase and divide by the original amount: 20-10 = 10 increase; 10/10 = 1.
The exponential function is of the form
f(x) = a*(1+r)ˣ, where a is the initial value (10), r is the growth rate (1), and x is the number of time periods. Using the variables given to us in the problem along with this information, we have:

Divide both sides by 10:

We will use logarithms to solve this:
Answer:
2 and 3 are same since in both the cases we need to square 2 only not the negative 1 in it
1 is not same to 2 and 3 since in 1 we need to square 2 and negative 1 in it also.
Step-by-step explanation:
We are given the three expressions different from each other
We are supposed to find what may be same or different.
1) 

2)

3)

Now 2 and 3 are same since in both the cases we need to square 2 only not the negative 1 in it
1 is not same to 2 and 3 since in 1 we need to square 2 and negative 1 in it also.
1/4 would be the answer. Let me explain why first. You have in total 4 numbers with different out comes when added together. So your equation will start out as 4² = 16 out of the 16 different factors you have 4 sets that equal 180°. Your new fraction would be 4/16 which can be divided by 4 to equal 1/4. Hopes that helps!
Answer:
Multiplication
Step-by-step explanation:
First multiplication 5x8=40 divided by 2 = 20 add back the three so the equation is now 20+3 =<u>23 The final answer</u>
Go by the order PEMDAS
P-Peretnahesis-there is none so skip this step
E-Exponents-There is none so skip this step
M-Multiplication-and division are mixed so whichever one comes first you do and then do the multiplication and division operations in the order they go
D-Division & multiplication are mixed so whichever one comes first you do and then do the multiplication and division operations in the order they go.
A-Addition and subtraction are mixed so whichever one comes first you do and then do the multiplication and division operations in the order they go
S-Subtraction-and addition are mixed so whichever one comes first you do and then do the multiplication and division operations in the order they go
