Answer:
Distance covered in 2 hours is 60 miles. So, David will cover 880 yards of distance in 1 minute.
We could write the 5/4 various ways but I think the reduced improper fraction is simplest.
They gave you the lengths showing each side of the original triangle is congruent to each side of the new triangle. There is no information to show if the triangle was rotated or reflected, so although it is possible that it was, we can't really tell. All we know is the triangles are congruent.
0.31 rounded to the nearest tenth would be 0.3

Answer:
b^2 = 5, a^2 = 4 and k= -2.
Step-by-step explanation:
In this case we have the first focus (-2, -2), the center (1, -2) and from the graph we can deduce that the distance between the vertices 2a is 4. So 2a=5 then a=2, thus, a^2 = 4.
The hyperbola is centered at the point (h, k) = (1, -2) thus we can conclude that h=1 and k = -2.
We can deduce from the graph that the distance from the center to each focus is 3, so c=3. (c represents de distance from center to focus).
We know that c^2 = a^2 + b^2
Solving for b^2, we have that:
b^2 = c^2 - a^2 = 3^2 - 2^2 = 5
Then b^2 = 5
