Answer:
y=3x-2
Step-by-step explanation:
The answer is 3 if I’m not mistaken
The formula for the distance between two points is
Note that, if two points have one coordinate in common, this formula simplifies to
(the first if they share the y coordinate, the second if they share the x coordinate).
So, these are the lengths of the sides:
(because they share the y coordinate)
(standard formula)
(because they share the y coordinate)
It would be 550x10 (5 tens = 50)
so you would solve for 550
<u> x10</u>
5500
Answer:
The magnitude of the boat's velocity is 5.66 m/s
Step-by-step explanation:
Given;
Radius of curvature of the circular path, r = 40 m
speed of the boat, v = 0.8 t m/s
The magnitude of the boat's velocity when it has traveled 20 m is ?
a = dv / dt,
v = 0.8 t (differentiate with respect to t)
dv / dt = 0.8 = a
thus, a = 0.8 m/s²
If the boat starts from rest, initial velocity, u = 0
Apply kinematic equation, to solve for the boat velocity at 20 m
v² = u² + 2as
v² = 0 + 2 x 0.8 x 20
v² = 0 + 32
v² = 32
v = √32
v = 5.66 m/s
Therefore, the magnitude of the boat's velocity when it has traveled 20 m is 5.66 m/s
