Substitute the variables for the values given.

9 + 11(2) - 4(7) =
9 + 22 - 28 =
31 - 28 =
3

So, 3 is the answer.

9 + 11g - 4h
9 + 11(2) - 4(7)
9 + 22 - 28
31 - 28

The final answer is 3.

Find all degree solutions in the interval 0° ≤ θ < 360°. If rounding is necessary, round to the nearest tenth of a degree. Us

xenn [34]

Answer:

$\theta_{1} \approx 30.473^{\textdegree}$

$\theta_{2} \approx 120.473^{\textdegree}$

$\theta_{3} \approx 210.473^{\textdegree}$

$\theta_{4}\approx 300.473^{\textdegree}$

Step-by-step explanation:

The equation needs to be rearranged in terms of one trigonometric function:

$5\cdot \sin 2\theta - 9\cdot \cos 2\theta = 0$

$5\cdot \tan 2\theta - 9 = 0$

$5\cdot \tan 2\theta = 9$

$\tan 2\theta = \frac{9}{5}$

$\theta = \frac{1}{2}\cdot \tan^{-1} \left(\frac{9}{5} \right)$

The tangent function has positive values in the 1st and 3rd Quadrants. Then, the solutions are:

$\theta_{1} \approx 30.473^{\textdegree}$

$\theta_{2} \approx 120.473^{\textdegree}$

$\theta_{3} \approx 210.473^{\textdegree}$

$\theta_{4}\approx 300.473^{\textdegree}$

Please help with 17 part b

skad [1K]

N - 93 > 175
n > 175 + 93
n > 268

So any numbers that are greater than 268 will be true.
(D) n = 300
(E) n = 312

Someone please help explain how to find x.

natta225 [31]

The exterior angles of any polygon will always add up to 360 degrees. Since we know all the values for every exterior angle, we can simply make the following equation:

3x + (x + 50) + 4x + (2x + 40) = 360

Simplify:

10x + 90 = 360
10x = 270
x = 27

If you want me to explain anything I did here, just ask :)
