Answer:
Step-by-step explanation:
87+95+76+88+x/5=85
346+x=85x5
x=425-346
x=79
Taking the point directly under the center of the bridge as the origin,
x = 20t, y = 15t, z = 10
let s be thedistance between them at time t,
s^2 = (20t)^2 + (15t)^2 + 10^2 = 625t^2 + 100
2s ds/dt = 1250t
ds/dt = 625t/s
when t = 3, s = √(625*9+100) = 75.6637
ds/dt = 625*3/75.6637 = 24.78 m/s
17/tan(65) = 7.9272 yards. If you need more explanation let me know!
Since, the coordinates of the midpoint of line GH are M.
The coordinates of endpoint G are (-4,1)
We have to determine the coordinates of endpoint H.
The midpoint of the line segment joining the points and is given by the formula .
Here, The endpoint G is (-4,1) So,
Let the endpoint H be
The midpoint coordinate M is .
So,
Now,
So, the other endpoint H is (-9,-13).
