Answer:
Step-by-step explanation:
You already have this set up to answer your question. This quadratic is in work form, aka vertex form, where the vertex is (3.5, 15). The first coordinate of the vertex is the time it takes to reach its max height, which is the second coordinate of the vertex. So it takes 3.5 seconds to reach a max height of 15 meters.
Answer: -1
Step-by-step explanation:
I assume the points are (-3, r) and (9,2).
Substituting into the slope formula,
If the radius of a circle is perpendicular to a chord, 1. the radius bisects the chord and 2. right angles are created at the point where they meet.
Answer:
u=2t-v
Step-by-step explanation:
t=(u+v)÷2 |×2
2t=u+v
-u=v-2t |:(-1)
u=-v+2t
u=2t-v
