What is the common difference and ninth term for the following sequence:
3,5/2,2,3/2,1

Common Difference:

The ninth term: -1

Step-by-step explanation:

The sequence can be written like this,

3, 2.5, 2, 1.5, 1, ....

Here the common difference is clearly -0.5 or , and we can conclude that number is . So the 9th term is,

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
