Answer:
2.25×3
Step-by-step explanation:
2 1/4 is equal to 2.25. So a expression could be 2.25×3.
<span>2 inches = 25 miles
?,,,,,,,,,,,,,,,</span><span>60 miles
</span>
60 x 2 / 25 = 4.8 inches
<span>1/4 = 0.25 inches
0.25 x 25 / 2 = 3.125 miles

Answer:
y=-3(x-1)^2+5
Step-by-step explanation:
The vertex form of a parabola is y=a(x-h)^2+k where (h,k) is the vertex.
We are given the vertex (h,k) is (1,5) so that makes the equation we have
y=a(x-1)^2+5.
We still need to find a.
We do have the point (0,2) on our parabola.
So replace (x,y) with (0,2) and solve for a.
2=a(0-1)^2+5
2=a(-1)^2+5
2=a(1)+5
2=a+5
-3=a
So the equation is
y=-3(x-1)^2+5
