Answer:

75

Step-by-step explanation:

15/.2=75

Z = 75

You can simply do the reverse operation of this, which would be division, and find the answer that way. 15/0.2 is 75 and that's your answer! You can check by doing "75 x 0.2", which would give you 15, your starting answer. Hope this helped!

Based on <em>trigonometric</em> formulas, we can find that the options that applies to the given <em>trigonometric</em> relationship are tan θ = 5/12 and cos θ = 12/13.

<h3>How to find the exact form of trigonometric functions</h3>

There six <em>trigonometric</em> functions, which are related by a group of expressions, which will be used in this question:

\cos \theta = \frac{1}{\sec \theta} = \frac{12}{13}

\sin \theta = \sqrt{1 - \cos^{2}\theta}

\sin \theta = \sqrt{1 -\left(\frac{12}{13} \right)^{2}}

\sin \theta = \frac{5}{13}

\csc \theta = \frac{1}{\sin \theta} = \frac{13}{5}

\tan \theta = \sqrt{\sec^{2}\theta - 1}

\tan \theta = \sqrt{\left(\frac{13}{12} \right)^{2}-1}

\tan \theta = \frac{5}{12}

Based on <em>trigonometric</em> formulas, we can find that the options that applies to the given <em>trigonometric</em> relationship are tan θ = 5/12 and cos θ = 12/13.

<h3>Remark</h3>

The statement is incomplete. Complete form is shown below:

<em>Check all that apply: </em>

<em />

<em>If sec θ = 13/12, then: </em>

<em />

<em>a) sin θ = 12/13</em>

<em>b) tan θ = 5/12</em>

<em>c) cos θ = 12/13</em>

<em>d) csc θ = 12/13</em>

A bouquet of flowers contains a total of 24 red and white roses. The number of red roses is 4 less than three times the number o
geniusboy [140]

Answer:

White roses - 7

Red roses - 17

Step-by-step explanation:

Set up proportional equations

White roses = x

Red roses = 3x - 4

Set equal to 24

x + 3x - 4 = 24

4x - 4 = 24

4x = 28

x = 7

x is white roses, so there are 7

Plug x value into red rose equation

3(7)-4

21-4 = 17 red roses

Check

17+7 = 24
