Answer:
100
Step-by-step explanation:
Multiply 50 by 2
Answer:
That is the solutions are:
,
Step-by-step explanation:
The period of 
or 
is 
.
Let's look at the first rotation to see when 
happens.
This happens at 
and also at 
. (Notice I just looked at the x-coordinates because that is what cosine is. Sine is the y-coordinate.)
Now to find the rest of the solutions we can just make full rotations either way to get back to those points .
That is the solutions are:
Answer:
Acute angle
Step-by-step explanation:
The probability of selecting one student who is both from math and science is 1/10
There are the total number of student = 300
Out of which,the number of students who are only in Maths = 120
The number of students who are only in Science = 50 and the students who are not from any subject = 100
<h3>What is the formula for the
total students?</h3>
Total no of students=science student+math students +none
Therefore,the number of student who are from both math and science = Total student - Math student (only) - science student (only) - None
= 300 - 120 - 50 - 100
= 30
That is, there are 30 students who are both from science and math,
Thus, the probability of selecting one student who is both from math and science = 30/300 = 1/10

There are 4 variables in the expression. The variables are: a,b,c and d.
8d^2 = variable d
2bc = variables b and c
10ab = variables a and b
