Yes, this is a parabola; it is a u-shaped graph.

The vertex is at (5, 120), and each corresponding point on either side of the graph is the same distance from the vertex.

Answer:

Yes. This is a parabola

Step-by-step explanation:

Yes. This is a parabola.

Reasons:

I. It is open down

2. Symmetrical about a vertical line

3. Has a vertex

4. Any point on the curve is equidistant from a point and a line.

Hence parabola

 <span>for the first part, realize that the hour and minute hands are moving at different rates; in one hour, the minute hands moves all the way around the face of the clock, and thus moves a total of 360 degrees or 2 pi radians; the hour hand moves only 1/12 away around the clock, so covers only 30 degrees or Pi/6 radians. 

Now, the LINEAR distance traveled by the tip of each hand is also determined by the length of the hand. In the case of the minute hand, it sweeps out a circle of radius 10 cm, so traces out a circle of radius 10 cm. Since the circumference of a circle is 2*pi*r, the minute hand (remember it made one complete cycle) covers a distance of 2*pi*10cm=20 Pi cm 

The hour hand covers only 1/12 a circle, but that circle is only 6 cm in radius, so the distance traveled by the tip of the minute hand is: 

1/12 *[2 *pi*r]=1/12*[12*pi]=pi 

so the difference is 19pi 

for the last part, you should draw a diagram of the two hands, the minute hand is 10 cm in length, the hour hand is 6 cm in length, and they are 30 degrees apart...from that drawing, see if you can figure out the remaining leg of the triangle you can form from them 

good luck</span><span>

Find the length of a rectangle given the information below.
ahrayia [7]

Answer:

156ft would be the answer

Step-by-step explanation:

Simple, 184-28=156. If it was the area you would divide 184 by 28 to get about 6.57.  

L+W=P

aka length + width= perimeter. But LxW=Area, LxW=A, or bXh (base times the height)
