if you could show me step by step please-Start by using the very useful identity sin(2x) = 2sin(x)cos(x).We can now write
2sin(x)cos(x)sin(x) = cos(x)
2cos(x)sin^2(x) = cos(x)
2cos(x)sin^2(x) - cos(x
I need to know the name of a mathematician who in some way has made a contribution that has advanced the field of mathematics. I also need to know how his/her contribution has changed something in soc
Do step by step, im only checking so if I screwed up I need to know where. Write an equation (slope-intercept form) m=5 and x-intercept is -2.-So we have m = 5 and the x-intercept is 2.
The x-interce
You can combine 5w and 3w since they have the same variable w so you would get 8w = 24 and you can divide both sides by 8 to get the solution of w = 3-8w=24 i,e w=3
1.a) In how many ways eight people be seated around a circular table?
b) In how many ways can they seated if Bob and Raj insist on sitting next to each other?

How would you solve tan2xcotx-3=0?
Thanks in advance :)-tan2x = 2tanx / 1 - tan^2x
cotx= 1 / tanx
Using these results you can simplify the equation to get:
2 / 1 - tan^2x = 3
3 tan^2x = 1
tan^2x = 1/
I see only two terms, so that immediately makes me wonder if it is a difference of squares. Are the two terms both perfect squares?
Yes they are.
So this is in the form (a^2 - b^2), and it factors a
So, my homework problem says, Solve the following equation for m. p = 6n - 5m/14.
My answer was m = 6n/5 - 14p/5
I checked my answer on an online calculator, and it said the answer was
m = 2 (7p -
can you tell me how to solve the question and give me the answer? thanks-The overall speed is 24/6 = 4 meters per second-Well you asked meters per second, so 24/6=4.
4m/s.-speed=velocity=distance/tim
According to the meteorologist for the weekend, there is 60% probability of rain for Wednesday and 70% probability of rain for Thursday. Whats the probability that:
a) it will only rain Wednesday
b) i
thanks-Difference of squares
4c^2 - 9 = 0
(2c + 3)(2c - 3) = 0
So if 2c + 3 = 0 then c = -3/2
And if 2c - 3 = 0 then c = 3/2
S = {-3/2, 3/2}-4c²-9=0
is a difference of two squares, so it factors as

I have 2 questions: m²+5m=0
and d²-21d=0
Thanks & explain! :}-m(m+5) = 0
m+5=0/m
m+5 =0
m = - 5
d( d- 21) = 0d -21 = 0d = 21-For real this is 10th grade stuff? Where I`m at we get this in the 7th g
1-if R and S are relations on set A then prove that a) R and S are symmetric=>RUS and R∩S are symmetricb) R is reflexive and S is any relation=> RUS is reflexive
2-If R and S are transitive relation
