Answer:
f has relative maximum at t =
and
f has relative minimum at t =
Step-by-step explanation:
Data provided in the question:
f(t) = -3t³ + 2t
Now,
To find the points of maxima or minima, differentiating with respect to t and putting it equals to zero
thus,
f'(t) = (3)(-3t²) + 2 = 0
or
-9t² + 2 = 0
or
t² =
or
t =
to check for maxima or minima, again differentiating with respect to t
f''(t) = 2(-9t) + 0 = -18t
substituting the value of t
at t =
f''(t) =
= - 6√2 < 0 i.e maxima
and at t =
f''(t) =
= 6√2 > 0 i.e minima
Hence,
f has relative maximum at t =
and
f has relative minimum at t =
Answer:
Step-by-step explanation:
Given: A bag contains 2 black balls, 4 yellow balls and 4 white balls.
Event A is defined as drawing a white ball on the first draw.
Event B is defined as drawing a black ball on the second draw.
P(B|A) is expressed as the conditional probability of occurring B given that A.
i.e. it is the probability of happening B where A is already happended.
If a white ball is drawn at first, then the number of black ball(4) remains unchanged but the total number of balls (10) will become 9.
Then,
No it is not a linear function
X = -2.1/3
I hope this helps
