the value of r of the geometric series n=11.3(0.8)n-1
General formula for nth term of any geometric series is
Here 'r' is the common ratio
a_1 is the first term of the series
Now we compare the given formula with general formula
Compare with
The value of r= 0.8
1. We've got everything to write the expression. Here it is: √48 - √27.
We can simplify it into:
1) (√16 * 3) - (√9 * 3);
2) 4√3 - 3√3;
3) √3.
2. Here we also have everything to write the expression which represents the total distance covered by this over the two day period. The expression looks like this: √750) + √1080.We were asked to simplify that:
1) (√25 * 30) + (√36 * 30);2) 5√30 + 6√30;3) 11√30.
3. The same situation. We have all we need to write an expression to represent the difference between the two distances of each route. Here is the expression: √605 - √500.
We need to simplify it:1) (√121 * 5) - (√100 * 5);2) 11√5 - 10√5;
3) √5.
4. We've got all values to write the expression which represents the total length across the diagonals of both circuit boards. It looks like this: √24 + √54.
Then let's simplify it step by step1) (√4 * 6) + (√9 * 6);2) (2√6) + (3√6);3) 5√6.
Answer:
9/4 divided 5/8 = 3.6 (Ans)
The answer is 2^12 = 4096.
Look at a tree diagram. With one spin there are two possible outcomes (branches). Every time you spin, each of the branches split into two more branches.
With 12 spins, first there are 2 branches, then 2*2, then 2*2*2, ... In the end it's 2^12
Answer:
n<2
