Answer:
C , 30 N
Step-by-step explanation:
Check the picture below.
now, let's rationalize the denominator for "r" first.
also notice, that section is just 1/4 of the area of that circle, so, let's just find the area of the whole circle with that "r", get one-quarter of it, and subtract it from the half of the area of the square.
Answer:
Value of x is 80 and yes they are vertical
Step-by-step explanation:
Answer:
d
Step-by-step explanation:
The given sample space S is
S={1,2,3,4,5,6}
The given event A and event B are
A={1,2} and B={3,4}.
As A and B have nothing in common i.e. A∩B={} thus, A and B are mutually exclusive.
As A and B are mutually exclusive then P(A or B) can be calculated as
P(A or B)=P(A)+P(B)-P(A∩B)
We know that if A and B are mutually exclusive events then P(A∩B)=0. So,
P(A or B)=P(A)+P(B)
In the given scenario
P(A)=n(A)/n(S)=2/6 and
P(B)=n(B)/n(S)=2/6
P(A or B)=2/6+2/6=4/6
P(A or B)=4/6
So, all the choices are correct
By graphing the given points, we will get the attached figure
which represents:
f(x) = 3 sin x
but sin x = cos (x - π/2)
∴ f(x) = 3 cos ( x - π/2 )
The correct choice is option ⇒⇒⇒ <span>f(x) = 3 cos(x − pi over 2 )
