For what values of θ is the tangent 0?

1 answer:

4 0

Tangent is actually the ratio of sine to cosine.
TanФ = sinФ/cosФ
Therefore, tangent becomes 0 when sin is 0; i.e at intervals of nπ(n is any integer starting from 0) and becomes undefined when cos is 0; i.e at intervals of nπ(n is any odd integer starting from 1).

Grant spent half of his weekly allowance. Then he earned $5 back by doing the dishes. What is his weekly allowance if he ended w

goldfiish [28.3K]

Answer:

Grant's weekly allowance is $20.

Step-by-step explanation:

We know that Grant ended with $15. We can say that Grant's weekly allowance is x.

x/2 + 5 = 15

Now to solve:

x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)

x/2 = 10

x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)

x = 20

Grant's weekly allowance is $20.
