Answer:
BD = 8
m∠BDA = 90°
∆ABD and ∆BCD are both right triangles, each with two known side lengths.
Step-by-step explanation:
Direct answer from PLATO so change it a bit.
<span>The
domain represents the A. horizontal distance covered by the flying disc. We see that x goes from x = 0 to x = 30, which the problem gives as the horizontal distance.
The range of this
function is B. 0, A. 7. The range is defined by the minimum y-value (y = 0, at x = 30), and the maximum y-value (y = 7, at x = 12).
For this function, the
range represents the flying disc's A. possible heights. This is the height as mentioned in the given, as it is the height of the disc being modelled on the graph as the disc travels horizontally.</span>
