Given sin theta = 1/3 and 0 theta pi/2 find tan 2 theta

Kazeer [188]

Answer:

$\tan2\theta=\pm\dfrac{4\sqrt{2}}{7}$

Step-by-step explanation:

Given: $\sin\theta = \dfrac{1}{3}$

$0\leq \theta \leq \dfrac{\pi}{2}$

Theta lie in first quadrant.

Multiply both sides by 2

$0\leq 2\theta \leq \pi$

2theta lie in I and II quadrant.

$\tan2\theta$ is positive in I and negative in II quadrant.

$\sin\theta=\dfrac{1}{3}$

$\cos\theta=\dfrac{2\sqrt{2}}{3}$

$\sin2\theta=2\sin\theta\cos\theta$

$\sin2\theta=2\cdot \dfrac{1}{3}\cdot \dfrac{2\sqrt{2}}{3}=\dfrac{4\sqrt{2}}{9}$

$\cos2\theta=\pm \sqrt{1-\sin^22\theta}=\pm\dfrac{7}{9}$

$\tan2\theta=\dfrac{\sin2\theta}{\cos2\theta}$

$\tan2\theta=\pm\dfrac{4\sqrt{2}}{7}$

Hence, The value of $\tan2\theta=\pm\dfrac{4\sqrt{2}}{7}$

You have 3 gallons of brown stock. You need 6 cups to make one serving of braised short ribs. How many servings can you make?

Vilka [71]

Answer: 8 servings can be made

Step-by-step explanation:

Concept:

As we can see from the question there are two different units applied [gallons] and [cups]; therefore, we need to do the unit conversion.

1 gallon = 16 cups

Solve:

Given there are 3 gallons of brown stock, we need to convert gallons into cups.

1 gallon = 16 cups
3 gallons = 16 × 3 = 48 cups

Then, divide 48 cups by 6 cups to find out how many servings can be made.

48 cups / 6 cups = 8 servings

Hope this helps!! :)
