Answer: 3. 4
4.
Step-by-step explanation:
8^2 + 12^3 = c^2
64 + 144 = c^2
208 = c^2
√208

The final answer is the square root of 208
8^2 + b^2 = 17^2
64 + b^2 = 289
-64 64
b^2 = 225

Answer: 
<u>Step-by-step explanation:</u>
The vertex form of a parabola is: y = a(x - h)² + k where
- (h, k) is the vertex
NOTE: p is the distance from the vertex to the focus
The vertex (h, k) is (2, -3)

Insert those values into the vertex formula to get:

3/4 an hour equals 45 minutes.
45 * 6 = 270 minutes over 6 days
1 hours = 60 minutes
270 / 60 = 4.50 hours
