wat is the solution for sinx-cosx=2 ?
whats the appropriate unit of measure for -5 1/4in - 2 2/3 in
Posted on Aug 26, 2008
cscx = 2 and cscx = -2
0 ≤ x ≥ 360
cscx=2 which can also be written as 1/sinx = 2/1
do the recipricol (flip it) and sinx = 1/2 which is pie/6 or 30 degrees.

1 + sinx = 2cos^2x
Hii..this can be done as follow
cos^2 x = 1 - sin^2 x--------(1)
2cos^2 x=1+ sin x
2cos^2 x - sin x -1=0
Substituting formula (1)
2(1 - sin^2 x) - sin x - 1 = 0
2sin^2 x + sin x - 1 = 0
Factor this
(2 sin x - 1)(sin x +1) = 0
2 sin x - 1 = 0 or sin x +1 = 0
sin x = 1, and sin x = -1

Radiation machines, used to treat tumors, produce an intensity of radiation that varies inversely as the square of the distance from the machine. At 3 meters, the radiation intensity is 62.5 milliroentgens per hour. What is the intensity at a distance of 2.5 meters?
Assume X is the intensity of the radition at 0 meters.
Then 62.5 milliroentgens/hr = 1/(3^2) * X
Solve for X. X = 9 * 62.5 milliroentgens = 562.5 milliroentgens/hr
Now solve for the radiation at 2.5 meters.
R = 1/(2.5^2) * 562.5 milliroentgens = 562.5/6.25 = 90 milliroentgens/hr
I hope this helps you out.

3x+6y=90 what is the y and x intercepts
By definition, the y-intercept is the value of y when x=0. Just set x=0 in the equation and solve for y.
Hence 3(0)+6y=90 or 6y=90. This gives y=90/6=15. The point of intercept of the y-axis is (0,15).
To get the x-intercept, set y= 0 in the equation and solve for x.
3x+6(0)=90 or 3x=90. This gives x=90/3=30.
The point of intercept of the x-axis is (30,0).

The formula for the volume of a cube is V(s) = s3 where s is the side length of the cube. In which quadrant(s) is the graph of the function V(s)?
The first. The pure function V(s)=s^3 is in the first and third, but it does not make sense to have a negative value for s.

what quadrants
All in the 1st as you can't have a negative radius meaningfully. If you do, the graph is in the 1st and 4th quadrants
Pi * r^2 * h is always a positive answer anyway.

A customer went to a garden shop and bought some potting soil for $11.50 and 9 shrubs. The total bill was $94.75. Write and solve an equation to find the price of each shrub.
9s = 94.75 - 11.50
Solving for s gives s = 9.25
This assumes each shrub costs the same.
