What is the constant of proportionality for the relationship between the number of cups of flour and the number of batches of cookies?
a.)0.25
b.)0.5
c.)2
d.)4

Step-by-step explanation:

1) To find tan m = 1/2 on a calculator, you need to take the inverse to find m.

(1/2) is about 26°.

So, m = 26°

2) To find tan n = -6 on a calculator, you also need to take the inverse.

(-6) is -80, which is positive 280°. (360° - 80° = 280°)

n = 280°

3) SO, the exact value of tan(m + n) would be tan(26° + 280°), which is tan(306°).

tan(306°) is about -1.376.

The closest answer to -1.376 is the third answer choice, which is -11/8.
