Solve tan^2x + tanx = 0

1 answer:

4 0

Factor out a tanx in order to not lose any solutions: tanx(tanx + 1) = 0
Thus, tanx = 0 or tanx = -1

Therefore, in general form, your solutions are:
$x = n \pi$ and
$x = n \pi - \frac{\pi}{4}$

At Davis you can buy 12 pounds of M&M's for $12.24 or 8 pounds for $8.24 at Smith's. Which is the better buy

Law Incorporation [45]

Answer:

12 pounds

Explanation:

If you were to divide 12.24 from 12 you would get 1.02, which would be the cost of each pound.

Meanwhile, if you were to divide 8.24 from 8 you would get 1.03, which would be the cost of each pound.

So although its only a 1 cent difference and you are technically spending more by buying the 12 pounds, if it were to buy 8 pounds from the cost of each pound for the 12 pounds, you'd only be spending $8.16 vs $8.24.

Because you would multiply 1.02, which is the cost of each pound for 12, by 8 and you would get 8.16.
