tan x = sin x/cos x
cos³ x *tan²x - cos x = cos³x *(sin²x/ cos² x) - cos= cosx*sin²x - cos x =
= cos x(sin² x - 1) = - cos x(1 - sin²x)= - cosx*cos²x = - cos³ x
Answer:
12(x+12y)
Step-by-step explanation:
Answer:
9.75
Step-by-step explanation:
6.5= 20% of 32.50
32.50+6.5= 39
39/4 = 9.75
The answer is X=5, X=-2 and x=-4
Answer:
4 / 20 (1 / 5)
20%
Step-by-step explanation:
The experimental probability is what actually happens in an experiment (as opposed to an authentic probability calculated from genetics).
In this experiment, there are 3 outcomes with :
3 tails and 1 head
(tails represent female, head represent male)
So, 4 / 20 of the time, this coin flip was what we call a "success" (meaning that it matches the guidelines that we want)
4 / 20 = 20% of the time
So, the probability of a group of 4 puppies being 3 females and 1 male is :
4 / 20 (1 / 5)
20%
