Answer: Choice A
----------------------------------
The first term is 8 as this is the y coordinate of the point when x = 1.
The second term is 4 (since y = 4 when x = 2)
etc etc
The sequence of terms is: 8, 4, 2, 1, ...
Each time we're dividing by 2, or multiplying by 1/2. This is why r = 1/2
Put this together and we have this geometric nth term formula
an = 8*(1/2)^(n-1)
This means the answer could be A or it could be C. However, we can rule out choice C because the rate of change is not positive. Draw a line through (1,8) and (3,2) and you'll see this line has a negative slope. So the rate of change is negative.
The only answer left is choice A.
Answer:
24
Step-by-step explanation:
The LCM of 8 and 12 is 24. Find least common multiple (LCM) of: 16 & 24 4 & 6 24 & 36 40 & 60 56 & 84 16 & 12 8 & 24 24 & 12 8 & 36 40 & 12 8 & 60 56 & 12 8 & 84
Answer:
1.you use a "carrot" it looks like this ^ so you put 6^3 an that is saying 6 to the power of 3
2. you can also use the symbols option and there is shows little numbers but only gives you the option for the power of 2 and 3
example: 6³
3. click equation option and put the x^2 and then delete the x and put the number or variable and then within the brackets put what the power should be.
Step-by-step explanation:
Answer:
I got the answer of 21.99115. Do I need to round too? If so, look up a rounding calculator and you can put in that decimal number and round to what the question says to round to.
I hope this helps!
