Y+5=-4(x-3) in standard form
dmitriy555 [2]

Answer:

y + 4x = 7

Step-by-step explanation:

Standard form is the form Ax + By = C. To get this lets put x and y on the same side alone.

y + 5 = -4(x - 3)

y + 5 = -4x + 12

y + 4x = 12 - 5

y + 4x = 7

What are the steps to understanding this problem as well as the answers.
svetlana [45]

Step-by-step explanation:

1

\frac{1}{3 + 4i}  \times  \frac{3 - 4i}{3 - 4i}  =  \frac{3 - 4i}{25}  =  \frac{ 3}{25} -  \frac{4i}{25}

2)

\frac{1}{3  -  4i}  \times  \frac{3  + 4i}{3  + 4i}  =  \frac{3  + 4i}{25}  =  \frac{ 3}{25}  + \frac{4i}{25}

3)

1+0i

4)

\frac{3 - 4i}{3 + 4i}  \times  \frac{3 - 4i}{3 - 4i}  =  \frac{ - 7 - 24i}{25}  =  -  \frac{7}{25}  -  \frac{24i}{25}

5)

3 - 4i

6)

\frac{3 + 4i}{3 - 4i}  \times  \frac{3 + 4i}{3 + 4i}  =  \frac{ - 7 + 24i}{25}  =  -  \frac{7}{25}  +  \frac{24i}{25}

Find sin θ if cot θ = - 2 and cos θ < 0
Masteriza [31]

Given was <span><span>cotθ</span>=−<span>21</span></span> and cot is the reciprocal of tan
therefore 
<span><span>tanθ</span>=<span>1<span>−2</span></span></span>
solve for the hypotenuse c since t he opposite side <span>a=1</span> and the adjacent sides <span>b=−2</span> were already given. that is,
<span><span>c2</span>=<span>a2</span>+<span>b2</span></span>
<span>c=<span>√<span><span><span>(1)</span>2</span>+<span><span>(−2)</span>2</span></span></span></span>
<span>c=<span>√5</span></span>

Solving for <span>sinθ</span>

<span><span>sinθ</span>=<span><span>oppositesides</span><span>hypoteνse</span></span>=<span>ab</span></span>

<span><span>sinθ</span>=<span>1<span>√5</span></span></span> need to rationalize
<span><span>sinθ</span>=<span>(<span>1<span>√5</span></span>)</span>×<span><span>√5</span><span>√5</span></span></span>

<span><span>sinθ</span>=<span><span>√5</span>5</span></span>

Note that the adjacent side of the angle is <span>−2</span> so the angle
θ is found in the <span>2nd</span> quadrant.

The 2010 General Social Survey reported a sample where about 48% of US residents thought marijuana should be made legal. If we w
Sati [7]

Answer:

The sample size is  n  = 600

Step-by-step explanation:

From the question we are told that

    The  sample proportion is  \r  p = 0.48

     The  margin of error is  MOE  =  0.04

Given that the confidence level is 95%  the level of significance is mathematically represented as

        \alpha  =  100 - 95

        \alpha  =  5 \%

        \alpha  =  0.05

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

                   Z_{\frac{\alpha }{2}  } =  1.96

The reason we are obtaining critical value of    \frac{\alpha }{2} instead of    \alpha is because  

\alpha represents the area under the normal curve where the confidence level interval (  1-\alpha) did not cover which include both the left and right tail while  

\frac{\alpha }{2} is just the area of one tail which what we required to calculate the margin of error

Generally the margin of error is mathematically represented as

      MOE  =  Z_{\frac{\alpha }{2} } *  \sqrt{ \frac{\r p(1-  \r p )}{n} }

substituting values

          0.04= 1.96*  \sqrt{ \frac{0.48(1-  0.48 )}{n} }

         0.02041 = \sqrt{ \frac{0.48(52 )}{n} }

         0.02041 = \sqrt{ \frac{ 0.2496}{n} }

          0.02041^2  = \frac{ 0.2496}{n}

           0.0004166 = \frac{ 0.2496}{n}

=>       n  = 600
