Answer:
a = -0.3575
Step-by-step explanation:
The points A and D lie on the x-axis, this means that they are the x-intercepts of the parabola, and therefore we can find their location.
The points A and B are located where
This gives
Now given the coordinates of A, we are in position to find the coordinates of the point B. Point B must have y coordinate of y=2 (because the base of the trapezoid is at y=0), and the x coordinate of B, looking at the figure, must be x coordinate of A plus horizontal distance between A and B, i.e
Thus the coordinates of B are:
Now this point B lies on the parabola, and therefore it must satisfy the equation
Thus
Therefore
Answer:
7,000
Step-by-step explanation:
The number of actual steps is x.
x + x(.05) = 7350 This is actual steps plus the extra 5% equals the number shown on the tracker.
Pull out x
x (1+.05) = 7350
x (1.05) = 7350 Divide by 1.05
(x (1.05))/1.05 = 7350/1.05
x = 7,000
