Answer:
I think it's 19.21, but in your case it would be 19.2. Sorry if I'm wrong
Y=-0.5x²+1.25
To find the vertex we need to write given equation in the vertex form.
y=a(x-h)²+k
(h,k) - coordinates of the vertex
y=-0.5x²+1.25 can be written as
y=-0.5(x-0)²+1.25
So, h=0, k=1.25
Vertex is (0, 1.25)

Answer:
10
Step-by-step explanation:
When the equation says that Jill bikes 2/3 hour at 18 mph, it means that the amount of miles she biked is 2/3 of 18. 18 divided by 3 is 6. 6 times 2 is 12, so she biked 12 miles. If she walks 2/5 hour at 5 mph, then she walked 2 miles because 5 divided by 5 is 1 and 1 times 2 is two. The question is asking how much more she biked than walked, so 12-2=10.
