Trigonometric Identities Help

iren [92.7K]

Recall that

$\sin^2\theta+\cos^2\theta=1$

So we have

$\sin^2\theta=1-\cos^2\theta=1-\left(\dfrac{\sqrt2}2\right)^2=1-\dfrac24=\dfrac12$

So either $\sin\theta=\pm\dfrac1{\sqrt2}=\pm\dfrac{\sqrt2}2$ .

Since $\dfrac{3\pi}2$ , we expect $\sin\theta$ , so we take the negative square root. Then

$\sin\theta=-\dfrac{\sqrt2}2$

This then means we have

$\tan\theta=\dfrac{\sin\theta}{\cos\theta}=\dfrac{-\frac{\sqrt2}2}{\frac{\sqrt2}2}=-1$

A line that includes the point (–1,4) has a slope of 1/4. What is its equation in SLOPE-INTERCEPT form?

Travka [436]

Answer:

$y=0.25x+4.25$

Step-by-step explanation:

Step 1: Determine the two forms

Point Slope Form → $(y-y_1)=m(x-x_1)$

Slope Intercept Form → $y=mx+b$

Step 2: Plug into point slope form

$(y-4)=0.25(x-(-1))$

$y-4=0.25(x+1)$

Step 3: Convert to slope intercept form

$y-4+4=0.25x + 0.25+4$

$y=0.25x+4.25$

Answer: $y=0.25x+4.25$

What is the output of the function when the input is 0

bearhunter [10]

Answer:

y = -1

Step-by-step explanation:

Any ordinate pair (x, y) represents the input output values of a function to be graphed.

For any input value of x, there will be an output value (y).

If input value for the graph attached is x = 0,

Output value will be represented by the y-value along y-axis as, y = -1

Therefore, y = -1 will be the answer.
