What is the vertex of the function f(x) = x2 + 12x?
saul85 [17]

Answer:

6, - 36 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

x = - \frac{b}{2a}

f(x) = x² + 12x ← is in standard form

with a = 1, b = 12, c = 0 , then

x = - \frac{12}{2} = - 6

Substitute x = 6 into f(x) for corresponding value of y

f(6) = 6² + 12(- 6) = 36 - 72 = - 36

vertex = (6, - 36 )

Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the .10 significa
nata0808 [166]

Answer:

 The  test statistics is t  =   -1.40

  The critical value is  Z_{\alpha }   = 2.33

   The null hypothesis is rejected

Step-by-step explanation:

From the question we are told that

   The sample size  for men is  n_1 =  80

    The sample  proportion of men that own a cat is  \r p _M  =  0.40

     The  sample  size for  women is n_2  =  80

     The sample  proportion of women that own a cat is  \r p_F  =  0.51

     The level of significance is  \alpha  =  0.10

   The  null hypothesis is  H_o  :  \r p _M   =  \ r P_F

    The alternative hypothesis is  H_a  :  \r p _M  <  \r p_F

Generally the test statistic is mathematically represented as

        t  =    \frac{(\r p_M - \r p_F)}{\sqrt{\frac{(p_M*(1-p_M)}{n_1 } }  +  \frac{p_F*(1-pF)}{n_2 } }

=>  t  =    \frac{(0.40  - 0.51)}{\sqrt{\frac{(0.40 *(1-0.41)}{80} }  +  \frac{0.51*(1-0.51)}{80 } }

=>   t  =   -1.40

The critical value of  \alpha  from the normal distribution table is

     Z_{\alpha }   = 2.33

The p-value  is obtained from the z-table ,the value is  

    p-value =  P( Z < -1.40) =   0.080757

=>    p-value = 0.080757

Given that the p-value  <  \alpha then we reject the null hypothesis

Please find the equation of the line using the given information.<br><br> (−2, 0) and (−2, 5)
steposvetlana [31]

Answer:

x=-2

Step-by-step explanation:

The first step is to find the slope

m = (y2-y1)/ (x2-x1)

   = (5-0)/(-2--2)

   = (5-0) /(-2+2)

   = 5/0

The slope is undefined

That means it is a vertical line  (up and down)  The x value does not change

x=-2
