Answer:
dx/dt= 0.2608 at h= 3.1 m
Step-by-step explanation:
a is the length of the ladder. a=5
by pythagorus theorem
differentiating with respect to t we get
......1
The variable h is the height of the ladder's top at time t, and x is the distance from the wall to the ladder's bottom
At h= 3.1
x^2= 6^2-3.1^2 = 9.1×2.9
x= 5.1371 m
given
putting values in 1 to get dx/dt
.
dx/dt= 0.2608 at h= 3.1 m

Answer:
(c)
<u>Total number of beads:</u>
(i)
<u>Probability of 2 red:</u>
- P(RR) = 15/25*15/25 = 9/25
(ii)
<u>Probability of no 2 red:</u>
- P(R'R') = 1 - 9/25 = 16/25
