Answer:
an = 2·2^(n-1)
Step-by-step explanation:
There are simple tests to determine whether a sequence is arithmetic or geometric. The test for an arithmetic sequence is to check to see if the differences between terms are the same. Here the differences are 2, 4, 8, so are not the same.
The test for a geometric sequence is to check to see if the ratios of terms are the same. Here, the ratios are ...
4/2 = 2
8/4 = 2
16/8 = 2
These ratios are all the same (they are "common"), so the sequence is geometric.
The general term of a geometric sequence with first term a1 and common ratio r is ...
an = a1·r^(n-1)
Filling in the values for this sequence, we find the general term to be ...
an = 2·2^(n-1)
The answer that results in an image located in Quadrant II is <span>C. rotate 90 degrees counterclockwise, then shift 1 unit up. This is because Quadrant II is located next (at the left) of Quadrant I. This means that a 90 degree rotation and a shift up are safe enough to estimate it to land on Quadrant II.</span>
Answer:
1. B
2. D
3. B
4. D
5. C
6. A
7. What is the estimated sum of "?" what are we estimating?
8. C
9. C
10. B
Step-by-step explanation:
1st question
1/4 ≤ 8/19 ≤ 3/4, so round it to 1/2.
1/4 ≤ 6/13 ≤ 3/4, so round it to 1/2.
Estimating:
1/2 + 1/2 = 1
2nd question
220 9/11 divided by 6 19/20 = 2.99542184434
Rounded/estimated = 3
3rd Question
Estimate 8 1/8 (common sense)
8 1/8 = 8.
4th Question
Assuming cups = 2.
2x24 = 48.
5th Question
3
6th Question
Add and estimate
7th question
What is the estimated sum of "?" what are we estimating?
8th question
6/7 > 3/4, so round it to 1.
1/4 ≤ 4/7 ≤ 3/4, so round it to 1/2.
Estimating:
1 + 1/2 = 1 1/2
9th Question
Round 7 to 8. It is over half, so it would be 8, which = 1
10th Question
Half of 20 = 10, 9 isn't above 10.
So round backwards to 24.
Step-by-step explanation:
Since we have 90° angle that means that side opposite of it is hypotenuse, so it goes:
a=10cm b=6 c=?
