Write the first five terms of each sequence described and identify the sequence as arithemetic or geometric. 1. The first term of the sequence is 8 and the common difference is 12. 2. The first term of the sequence is -9 and the common ratio is -2. 3. The first term of the sequence is 0 and the common difference is -6. 4. The first term of the sequence is -3 and the common ratio is -1/4.

Find the value of x that will make l ll m

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?

Sketch the region enclosed by the given curves. decide whether to integrate with respect to x or y. draw a typical approximating rectangle and label its height and width. y= 5x, y=7x^2then find the area s of the region.
