Answer:
n = 24
p(a) = 10/24
p(b) = 15/24
[ p(a) + p(b) - [p(a) ×p(b)] ] -1 = answer
[ 35/24 - 6/24 ] -1 = 39/24 - 24/24 = 5/24
This formula only applies if the track is circular. If it is, then we write the equation:
2*r*pi=400
Dividing by 2pi, we see that:
r=200/pi
This is approximately 63.66.
The sum of the first n natural numbers and 0=
n*(n+1)/2
Answer:
Initial height of the anchor is 75 meters.
Step-by-step explanation:
We are given the following in the question:

where, I is the anchor's elevation in meter after t seconds dropped from the ship.
We have to find the initial height of anchor that is we have to put t = 0 in the equation.
Putting t = 0, we get,

Thus, initial height of the anchor is 75 meters.
