Answer: ABC EASY AS 123
Step-by-step explanation:
<span>It introduces the relationship between two variables and is called correlation. Proportionality or variation is state of relationship or correlation between two variables It has two types: direct variation or proportion which states both variables are positively correlation. It is when both the variables increase or decrease together. On the contrary, indirect variation or proportion indicates negative relationship or correlation. Elaborately, the opposite of what happens to direct variation. One increases with the other variables, you got it, decreases. This correlations are important to consider because you can determine and identify how two variables relates with one another. Notice x = y (direct), y=1/x (indirect)

Average rate of change can be calculated by the following
Δy/Δx
Our Δx refers to displacement.
Δx = 4 - 64 = -60
Our Δy refers to our Δf(x)
To get our f(x) values, we must plug in 64 and 4 into the function f(x)
f(64) = 8√64 = 64
f(4) = 8√4 = 16
Δf(x) = 16 - 64 = -48
So our rate of change is -60/-48 = 0.8
I believe the answer should be positive 0.8, but that's my best estimate.
Answer:
18. is 2×2×2×2×2×2×2=128
19. is 4×4×4×4×4=1,024
20. is 5^4 which is 625
21. the student did 3^2 which it asks for 2^3 so the answer is 2×2×2=8
22. it is 10^10 because the difference is 2 billion while the other number's difference is 92 billion
23. exponential form is when a certain number is raised to the power of a certain number or also known as exponents. Exponents signifies that the number that is being being raised to a certain power will be multiplied a number of times, based on the exponent
