Answer:

Step-by-step explanation:
We want to write a quadratic function in vertex form whose vertex is (1, 0) and passes through the point (2, -17).
Recall that vertex form is given by:

Where (<em>h</em>, <em>k</em>) is the vertex and <em>a</em> is the leading coefficient.
Since our vertex is at (1, 0), <em>h</em> = 1 and <em>k</em> = 0:

It passes through the point (2, -17). Hence, when <em>x</em> = 2, <em>y</em> = -17:

Solve for <em>a: </em>

In conclusion, our quadratic function in vertex form is:

Answer:
Step-by-step explanation:
- Speed = Distance/Time
- => Speed = 15 km ÷ 13/60
- => Speed = 15 km ÷ 0.216
- => Speed = 15 km/0.216
- => Speed = 15 x 4.63/0.216 x 4.63
- => Speed = 69.45 km/1 h (Approximate)
<u>Conclusion:</u>
- Therefore, the speed is 69.45 km/h (Approximate)
