Mike earns $11.50 an hour <br><br> Write a linear function for the given in formation.

Otrada [13]

Answer: y = 11.50x

Step-by-step explanation:

linear function format:

y = mx + b

since its linear and it starts from 0, b is 0 since there is no addon

y = mx

x is the number of hours, y is the payment incrementing by 11.50 per hour, making 11.50 our gradiant

So y = 11.50x

1 hour = 11.50 * 1

2 hour = 11.50 * 2 and so on

Pre-calc questions (trignometry)

miv72 [106K]

Answer: (1a) 250° (1b) 70° (2) see below

<u>Step-by-step explanation:</u>

1a) -110 + 360 (one rotation clockwise) = 250°

1b) 430 - 360 (one rotation counterclockwise) = 70°

2) sec Ф = -8/5 in Quadrant III

Quadrant III identifies that both sin (y) and cos (x) are negative.

sec = r/x --> r = 8, x = -5, and y = -√39

(Use Pythagorean Theorem x² + y² = r² to solve for y)

$\sin\theta=\dfrac{y}{r}=\dfrac{-\sqrt{39}}{8}$ $\csc\theta=\dfrac{r}{y}=\dfrac{-8}{\sqrt{39}}$ rationalized = $\dfrac{-8\sqrt{39}}{39}$

$\cos\theta=\dfrac{x}{r}=\dfrac{-5}{8}$ $\sec\theta=\dfrac{r}{x}=\dfrac{-8}{5}$ (GIVEN)

$\tan\theta=\dfrac{y}{x}=\dfrac{\sqrt{39}}{5}$ $\cot\theta=\dfrac{x}{y}=\dfrac{-5}{-\sqrt{39}}$ rationalized = $=\dfrac{5\sqrt{39}}{39}$

NOTE THAT YOU ARE ALLOWED A MAXIMUM OF 3 QUESTIONS PER POST. Please repost #3 and #4 as a different question and I will answer them.
