The bar graph shows in the attachment bases on frequency distribution equation for Lunch is 68:22:10 which mean the equation is 68x+22y+10 is the combined information.

Step-by-step explanation:

  • Column lunch and row had Pizza,Hamburger and Sloppy joe.
  • The total 548,173 and 79 total to 800 students.
  • Creating a bar graph series name is lunch and series value is pizza....
  • hamburgers and sloppy joes.
  • Frequency distribution basis on percentage involves...
  • Number of categories/ Total number of students.
  • 68:22:10 so the distribution has about 68 percent of people....
  • Eat pizza more than hamburger and sloppy joes.

As shown in the question, the translation changes the points as follows:

(x,y)\rightarrow(x+2,y-2)

Therefore:

\begin{gathered} C(-5,-1)\rightarrow C^{\prime}(-3,-3) \\ D(-4,3)\rightarrow D^{\prime}(-2,1) \\ E(-3,2)\rightarrow E^{\prime}(-1,0) \\ F(-2,0)\rightarrow F^{\prime}(0,-2) \end{gathered}

The height h in feet of a ball thrown vertically upward from the top of a 288-foot tall building is given by h=288+48t-16t^2 whe
mr Goodwill [35]

6 sec can take penny to strike the ground.

Solution:

Given data:

H_0=288 feet

V_0=48 feet

h(t)=288+48t-16t^2

Re-arrange the terms from greatest degree to smallest degree.

h(t)=-16t^2+48t+288

We can solve it by applying quadratic formula,

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}

Here a = –16, b = 48, c = 288

$t=\frac{-48\pm \sqrt{48^2-4(-16)(288)}}{2(-16)}

$t=\frac{-48\pm \sqrt{2304+18432}}{-32}

$t=\frac{-48\pm \sqrt{20736}}{-32}

$t=\frac{-48\pm144}{-32}

Now, write find two t's using plus and minus operation.

$t=\frac{-48+144}{-32},\ \ t=\frac{-48-144}{-32}

$t=\frac{96}{-32},\ \ t=\frac{-192}{-32}

t = –3 (or)   t = 6

We cannot write time is negative. so neglect t = –3.

Therefore t = 6.

Hence 6 sec can take penny to strike the ground.
