The list of the buildings arranged in the order from shortest to tallest

  • Marina 101
  • The Wuhan Center
  • The Zifeng Tower
  • The Shanghai tower

The heights in feet shows that

2072 feet(is the tallest) > 1,476 feet >  1,437 feet > 1400 feet (is the least)

<h3>How to arrange the buildings from shortest to tallest</h3>

Given that the z scores are 127 for The Shanghai tower and -0.84 for Marina

z score = (X - mean) / standard deviation

X = z score * standard deviation + mean

The Shanghai tower

= 1.27 * 318.31 + 1667.25 = 2071.5037 feet

Marina 101

= -0.84 * 318.31 + 1667.25 = 1399.8696 feet

The Zifeng Tower

= 1,476 feet

The Wuhan Center

= 1,437 feet

comparing the heights

2072 feet > 1,476 feet >  1,437 feet > 1400 feet

What is the equation of the quadratic graph with a focus of (6, 0) and a directrix of y = −10 ?
Mademuasel [1]

Answer:

(x-6)^{2}=20(y+5)^{2}


Step-by-step explanation:

The standard for for the equation of a parabola is  (x-h)^{2}=4p(y-k)

The focus is given as  (h, k+p)

The directrix is given by y=k-p

  • Comparing focus given as (6,0)  to formula of focus (h,k+p) , we see that h=6 and k+p=0
  • Comparing directrix given as y=-10  to formula of directrix y=k-p , we can write k-p=-10

We can use the two system of equations [ k+p=0  and  k-p=-10 ] to solve for k  and  p.

<em>Adding the two equations gives us:</em>

2k=-10\\k=\frac{-10}{2}\\k=-5

<em>Using this value of k , we can find p  by plugging this value in either equation. Let's put it in </em><em>Equation 1</em><em>. We have:</em>

k-p=-10\\-5-p=-10\\-5+10=p\\p=5


Now, that we know h=6  ,  k=-5  ,  and p=5  , we can plug these values in the standard form equation to figure out the parabola's equation. Doing so and rearranging gives us:

(x-6)^{2}=4(5)(y-(-5))^{2}\\(x-6)^{2}=20(y+5)^{2}\\

This is the equation of the parabola with focus (6,0)  and directrix  y=-10
