Answer:

The expression simplifies to:

= \frac{\tan\theta}{\sin ^2 \theta+\cos ^2 \theta}=\tan\theta}

Step-by-step explanation:

Given trigonometric expression:

\frac{\tan\theta}{\sin ^2 \theta+\cos ^2 \theta}

Using identity :

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

\frac{\tan\theta}{\sin ^2 \theta+\cos ^2 \theta}

=\frac{\tan\theta}{1}

The expression simplifies to:

= \frac{\tan\theta}{\sin ^2 \theta+\cos ^2 \theta}=\tan\theta}

An Article a Florida newspaper reported on the topics that teenagers most want to discuss with their parents. The findings, the

Answer:

The estimate is  P__{hat}} \pm E  = 0.37 \pm 0.0348

Step-by-step explanation:

From the question we are told that  

    The sample size is  n =  522

    The sample proportion of students  would like to talk about school is  \r p__{hat}} =  0.37

  Given that the confidence level is  90 % then the level of significance can be mathematically evaluated as

                  \alpha  =  100 - 90

                  \alpha  =  10\%

                  \alpha  =  0.10

Next we obtain the critical value of  \frac{\alpha }{2} from the normal distribution table, the value is  

               Z_{\frac{\alpha }{2} } =Z_{\frac{0.10}{2} } =  1.645

Generally the margin of error can be mathematically represented as

               E =  Z_{\frac{\alpha }{2} } *  \sqrt{\frac{\r P_{hat}(1- \r P_{hat} )}{n } }

=>            E = 1.645 *  \sqrt{\frac{0.37 (1- 0.37  )}{522 } }

=>             E = 0.0348

Generally the estimate the proportion of all teenagers who want more family discussions about school at 90% confidence level is  

                       P__{hat}} \pm  E

substituting values

                     0.37 \pm 0.0348

Unit 7:Polygons & Quadrilaterals Homework 4: Rhombi and squares​
iogann1982 [59]

Based on the quadrilateral given, the values of the missing measures will be:

  • VU = 15
  • SU = 21.21
  • TV = 21.21
  • SW = 10.61

<h3>Solving quadrilateral.</h3>

A quadrilateral simply means a polygon that has four sides, edges and vertices.

Based on the information given, SU = TV and this will be:

= ✓450 = 21.21

SW = 21.21/2 = 10.61

Also, for the second shape, the values will be:

OM = 46; PN = 23, ON = 46; MN = 46.

A. The two listed added up will be 180 degrees.

5x - 57 + 3x + 5 = 180

8x - 52 = 180

8x - 52 + 52 = 180 + 52

8x = 232

x = 29

B. The two listed added up will be 180 degrees.

2x + 4x + 150 = 180

6x + 150 = 180

6x + 150 - 150 = 180 - 150

6x = 30

x= 5
