Answer:
600 *10=6000 if each of these are of 10
52 kilometers in 4 hours = 52 x 4 = 208 km in 4 hours
Total of 5 hours = 208 km + 62 km = 270 km
Average speed = 270 km / 5 hours = 54 km per hour
Answer
54 km per hour
<span>there was a 10% decrease</span>
<span> we have that
standard form of equation for parabola:
(x-h)^2=-4p(y-k)
(h,k) --------->being the (x,y) coordinates of the vertex.
Parabola opens downwards because focus is below vertex on the axis of symmetry.
For given problem:
</span><span>vertex: (-3,2)
axis of symmetry: x=-3
p=distance from vertex to focus on the axis of symmetry=2-(-1)=3
4p=12
Directrix: y=2+p=5
Equation:
(x+3)^2=-12(y-2)
the answer is </span>(x+3)^2=-12(y-2)
Answer:
option C : 2
Step-by-step explanation:
because there can be one triangle from BA till 20cm . and other till D
