Independent influences the dependent
hours worked influences pay
independent=hours worked
dependent=pay

domain is input or hours worked, from 0 to 40

range is ouput or in this cas pay
if work 0 hours, get 0 dollars
if work 40 hours, get 40*12=480
range is from 0 to 480

hours worked, pay, 0 to 40, 0 to 480

16 2/3 divided 5 5/7

Stells [14]

$16\frac{2}{3} : 5\frac{5}{7} = \\ \\ = \frac{16 \times 3 + 2}{3} : \frac{5 \times 7 + 5}{7} = \\ \\ = \frac{50}{3} : \frac{40}{7} = \\ \\ = \frac{50}{3} \times \frac{7}{40} = \\ \\ = \frac{350}{120} = 2.91(6)$

Consider ∠A such that cos A = 12/13.

Georgia [21]

Using the unit circle, for the cos function to be positive, angle A must lie in either quadrant I or quadrant IV

Using the unit circle, If the sine is negative, angle A must lie in either quadrant III or quadrant IV. Since we know that the cosine is positive, this only leaves quadrant IV

cos = adj/hyp

Using Pythagorean theorem,

$12^{2} +b^{2} = 13^{2}$

b = ±5 (we know its -5 since we know sinA is negative)

this means that the x coord is 12, and the y coord is -5

any proportion of these two numbers would work as an answer

e.g. (12, -5), (24,-10), (12/13, -5/13), are all valid answers

sinA = opp/hyp

sinA = -5/13

tanA = opp/adj

tanA = -5/12
