Answer:
4t^2 + t - 1.
Step-by-step explanation:
(3t^2 + 2t −2 )+(t^2 + 3t − 4) − (4t − 5)
= 3t^2 + 2t −2 + t^2 + 3t − 4 - 4t + 5
= 4t^2 + t - 1.
Answer:
9 and 12
Step-by-step explanation:
Step-by-step explanation:
The equation of a parabola that relates it focus is

So here, we isolate x^2.


Next, we factor out 4.

Our p=8 so this tells us the distance of the vertex to the focus.
Answer:
x ≈ 46.49
Step-by-step explanation:
Use Cosine. (
)
Cos43° = 
34 ÷ Cos43° = x
x = 46.48913368...
x ≈ 46.49
