Answer:
The graph is constant in the interval [4,6]
Step-by-step explanation:
We are given that,
Taylor dropped a rubber ball from a height of 8 feet.
So, at time t= 0 sec, the ball is being thrown.
Now, the next events follows as below:
1. After a second, the ball hits the ground.
2. It bounces up to 5 feet in the next second.
3. The ball again hits the ground in the next second.
4. Now, the ball again jumps up to height 2.5 feet, when Taylor holds the ball for 2 seconds more.
So, we get the figure given below, we see that,
The graph is constant in the interval [4,6].
See the picture attached.
We know:
NM // XZ
NY = transversal line
∠YXZ ≡ ∠YNM
1) <span>We know that ∠XYZ is congruent to ∠NYM by the reflexive property.</span>
The reflexive property states that any shape is congruent to itself.
∠NYM is just a different way to call ∠XYZ using different vertexes, but the sides composing the two angles are the same.
Hence, ∠XYZ ≡ <span>∠NYM</span> by the reflexive property.
2) Δ<span>XYZ is similar to ΔNYM by the AA (angle-angle) similarity theorem
The AA similarity theorem states that if two triangles have a pair of corresponding angles congruent, then the two triangles are similar.
Consider </span>Δ<span>XYZ and ΔNYM:
</span>∠YXZ ≡ <span>∠YNM
</span>∠XYZ ≡ ∠NYM
Hence, ΔXYZ is similar to ΔNYM by the AA similarity theorem.
