Five thirds = 5/3
One half = 1/2
Just use the division symbol, as thats what fractions really are. Division.
Gotta' be careful here, EP.....dividing out sin x is like throwing away a polynomial root....
sin x - 2sin x cos x = 0
sin x ( 1 - 2cosx) = 0
So
sin x = 0 at 0° + n*180° where n is an integer .....or
1 - 2cosx = 0
1 = 2cos x
1/2 = cos x at 60° + n360° and at 300° + n360°

You know gov't jobs have to go out to bid and usually wind up with union work and waste....LOL
Volume of a sphere is 4/3 pi r^3
4/3 pi (r^3) = 4.5
r^3 = (4.5 x 3/4 )/ pi
r^3 =1.07429586
r= 1.024176 units (you didn't specify units in your question)
1094.97/2

x2+4-100
x2-96
200. there are 100 cm in one meter
A googol is a number that is equal to 1*10100
If f(x)=x+5 then f -1(x)=x-5 because subtraction is the inverse of addition.
4.25 moles x 6.022 x 10^23 atoms/mole = 25.59 x 10^23 atoms or 4.25 moles they are the same .....
HI. How many ATOMS of sulfur are present in 4.25 moles of sulfur tetrafluoride ? {nl} atoms of sulfur.
1.02374 • 1025
I have done this in detail, but my answer has disappeared. asinus
sqrt (7/81) = sqrt 7 / sqrt 81 = sqrt 7 / 9 = 2.64575/9 = .29397 Whichever one you want !
If you want to simplify this as far as you can, you'd sq. rt. the top and the bottom.
√7 √7
------- = -------
√81 9
If you want to get an approximate answer, then you'd just plug √(7/81) into your calculator.
This equals 0.2939723678960656
re-arrange to get
2 sinx cos x = sinx divide both sides by sinx
2 cosx = 1
cosx = 1/2
x = arcos(1/2) = 60 degrees (pi/3) or - 60 degrees (- pi/3)
Pfff . . .$50,000 my foot! Five cents worth of duct tape would have fixed it.
THAT's FUNNY !!! Good job.
I guess theis is a PEDMAS question?
y-2(3-1)^2 = 7
y-2(2)^2 =7
y - 2(4) = 7
y-8 =7
y = 15
Sulfur tetra flouride formula is SF4 so there are 4.25 moles of sulfur ATOMS in there.
You technically just called every Guest old
How do you know?
yup
