ANSWER

The vertex of this parabola is (-7,4)

EXPLANATION

The given parabola has equation:

{y}^{2}  - 4x - 8y - 12 = 0

{y}^{2}  - 8y = 4x +12

Complete the square for the quadratic equation in y.

{y}^{2}  - 8y +  {( - 4)}^{2}  = 4x + 12 +  {( - 4)}^{2}

{y}^{2}  - 8y +  {( - 4)}^{2}  = 4x + 12 +  16

{( y- 4)}^{2}  = 4x + 28

{( y- 4)}^{2}  = 4(x +7)

The vertex of this parabola is (-7,4)

What is the number of degrees in the smaller angle formed by the hour and minute hands of a clock at 5:44?
Arisa [49]

The hour hand of the clock moves 360 degrees in 12 hours.

The quantity of degrees the hour hand moves per hour is in this way 360/12 = 30 degrees.

The hour hand of the clock moves 360 degrees in 12 *60 = 720 minutes.

The quantity of degrees the hour hand moves every minute is accordingly 360/720 = 1/2 degrees.

So the hour hand moves 1/2 degree for each minute.

The minute hand moves 360 degrees in a one hour.

The quantity of degrees the minute hand moves every minute is accordingly 360/60 = 6 degrees.

At 5:44, the quantity of minutes the hour hand has moved is 5 * 60 + 44 = 344 minutes.

At a half degree for each minute, the hour hand has moved .5 * 344 = 172 degrees.

At 5:44, the quantity of minutes the minute hand has moved is 44 minutes.

At 6 degrees for each minute, the minute hand has moved 6 * 44 = 264 degrees.

The angle between the minute hand and the hour hand is along these lines 264 degrees minus 172 degrees = 92 degrees.

<span>Since that angle is under the 180 degrees, it must be the littler edge between the hour hand the minute</span>

A large diamond with a mass of 4289.6 grams was recently discovered in a mine. If the density of the diamond is 3.51 grams over
sweet [91]
There are several information's already given in the question. Based on those information's the answer can be deduced.
Mass of the diamond = 4289.6 grams
Density of the diamond = 3.51 gm/cm^3
Then
Volume of the diamond = 4289.6/3.51
                                      = 1221.9 cm^3
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the third option or the penultimate option.

Hey there!

In order to answer this question, it's easiest to start with one of the money amounts and work your way to the other ones. Keep in mind that, no matter what, the amount of collective money won't exceed 1.50, meaning you can't have two 1 dollar bills, etc. When I wrote it out, I did it in this order:

1 = 1 dollar
0.5 = Half dollar
0.25 = Quarter

1 + 0.5 = 1.50
1 + 0.25 + 0.25 = 1.50
0.5 + 0.5 + 0.5 = 1.50
0.5 + 0.5 + 0.25 + 0.25 = 1.50
0.5 + (0.25*4) = 1.50
0.25*6 = 1.50

Since no other combinations add up to 1.50, your answer is 6. 

Hope this helped you out! :-)
