Solve tan theta +1=-2tan theta

Ugo [173]

Answer:

$\boxed{135\°,315\°}$

Step-by-step explanation:

Solve the trigonometric equation by isolating the function and then taking the inverse. Use the period to find the full set of all solutions.

$\theta = 135+180n$

$n$ is any integer value.

The value of $n$ cannot exceed 1 or be less than 0, because the value of $\theta$ must be between 0 and 360 degrees.

$\theta = 135+180(0)$

$\theta = 135$

$\theta = 135+180(1)$

$\theta = 315$

Complete the data table for the function f(x) = -x - 2 + 2.

alexgriva [62]

Given the following function:

$\text{ f(x) = }\sqrt[]{-x\text{ -2}}\text{ + 2}$

y = f(x)

Therefore, let's complete the data table by substituting each x-values to be able to get the respective y-values,

We get,

At x = -2,

$\text{ y = f(x) = }\sqrt[]{-x-2}\text{ + 2}$ $\text{f(-2) = }\sqrt[]{-(-2)-2}\text{ + 2}$ $\text{ = }\sqrt[]{2\text{ - 2}}\text{ + 2}$ $\text{ = }\sqrt[]{0}\text{ + 2}$ $\text{ y = f(-2) = 2}$

Therefore, y = 2 at x = -2.

At x = -3,

$\text{ y = f(x) = }\sqrt[]{-x-2}\text{ + 2}$ $\text{f(-3) = }\sqrt[]{-(-3)-2}\text{ + 2}$ $\text{= }\sqrt[]{3-2}\text{ + 2}$ $\text{= }\sqrt[]{1}\text{ + 2}$ $\text{= }1\text{ + 2}$ $\text{ f(-3) = 3}$

Therefore, y = 3 at x = -3.

At x = -6,

Explain how the statement "there is 3/4 cup per serving" represents a rate.

Aleonysh [2.5K]

There is 3/4 cup of whatever in one serving. If that serving amount changed to 2, then the 3/4 would be multiplied by 2. If there is half a serving, then it would be divided by 2. There is a constant change, and not one that is always changing.
