The point will move 37.68 feet in a hour.
The circumference of the circle, also known as the perimeter of the circle, is the measurement of the circle's boundary. The area of a circle, on the other hand, defines the region it occupies. If we open a circle and draw a straight line through it, the length of the line is the circumference. It is typically measured in units such as centimetres or metres.
We have the minute hand is 6 ft long.
So, the radius = 6 feet
Then, the distance travelled by the tip is
= 2πr
= 2 x 3.14 x 6
= 12 x 3.14
= 37.68 feet
Thus, the minutes hand travel 37.68 feet.

Answer:
the graph of the parabola opens upwards.
Step-by-step explanation:
For any quadratic equation of the form
is true that:
if the main coefficient "a" is negative then the graph of the parabola opens downwards.
If the main coefficient "a" is positive, the parabola opens upwards
In this case the parabola is
Note that and therefore the graph of the parabola opens upwards.
