Answer:
28.83
Step-by-step explanation:
8.54 + 12.37 + 7.92 = total miles ran
28.83 total miles ran
Sure this question comes with a set of answer choices.
Anyhow, I can help you by determining one equation that can be solved to determine the value of a in the equation.
Since, the two zeros are - 4 and 2, you know that the equation can be factored as the product of (x + 4) and ( x - 2) times a constant. This is, the equation has the form:
y = a(x + 4)(x - 2)
Now, since the point (6,10) belongs to the parabola, you can replace those coordintates to get:
10 = a (6 + 4) (6 - 2)
Therefore, any of these equivalent equations can be solved to determine the value of a:
10 = a 6 + 40) (6 -2)
10 = a (10)(4)
10 = 40a
If the grist mill completes the rotation in 8 seconds. Then the final position of the bucket after 6 seconds is (0, 9).
<h3>What is coordinate geometry?</h3>
Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.
A water grist mill has a radius of 9ft and takes 8 seconds to make a complete rotation. a bucket starts at position (9,0).
Then the coordinates of the bucket's location after 6 seconds will be
The angle of rotation after 6 seconds will be
Then we have
x = 9 cos 270°
x = 0
and y will be
y = 9 sin 270°
y = -9
But the angle is in a clockwise direction, then
y = 9
