Hit the "2nd" button, then hit tan.
Just divide 275,000,000 by 2,500,000,000, and multiply the decimal by 100 to get the percent.
y=7 would be a horizontal line... therefore, it has a slope of zero.
If you are talking about real numbers, then there's no solution. There is an imaginary solution, which is i, the square root of -1.
square root of -4=2i
square root of -9=3i, etc.
Combine like terms:
4x^8-5x^8=-x^8
3x-70x=-67x
-34-(-42)=8.
-x^8-67x+8 is the result.
Just hit the "2nd" button.
3.05/5=0.61
7-3=4
It would be 6.1*(10^3), since in scientific notation, the first term has to be more than one but less than 10.
You would do cos^-1(b/c).
Just find (sin 75°)*75 to figure out.
All you need to do to find ? is to divide 15,000 by 93.62.
