Answer:
.09,1/6,1/3,2/5
Step-by-step explanation:
Answer:
(5,3)
Step-by-step explanation:
Look for the coordinates of the point of intersection where the 2 graphs cross. This gives the solution.
In this case, they cross at (5,3) and they intersect at only one location (i.e there is only 1 solution)
Answer:
v = 9
Step-by-step explanation:
Since the triangles are similar then corresponding angles are congruent
∠B and ∠Q are corresponding angles, hence
6v - 5 = 5v + 4 ( subtract 5v from both sides )
v - 5 = 4 ( add 5 to both sides )
v = 9
Answer:
Step-by-step explanation:
Let the speed of the roller coaster at the bottom is v.
radius, r = 47 m
Let the mass is m and the force at the bottom is 2.5 times the weight.
F = 2.5 mg
So, the force is



v² = 1.5 gr
v² = 1.5 x 9.8 x 47
v = 26.3 m/s
