graph y=sin(x-pie/4) (couldn't find pie sign on my keyboard) Use 3.1459 We can't draw graphs for you here, but you can certainly make a table of values of x and corresponding values of y, and draw the graph yourself. you might save a little time by recognizing that sin (x - pi...

From a point on ground level, you measure the angle of elevation to the top of a moutain to be 38 degrees. Then you walk 200 m fartheraway from the mountain and find that the angle of elevation is now 20 degrees. Find the height of the mountain. Round the answer to the nearest...

i need to show that the given equation is an identity. using composite argument properties. (cosAcosB-sinAsinb)^2 + (sinAcosB+cosAsinB)^2 = 1 Composite argument properties: cos(A + B) = cosAcosB - sinAsinB sin(A + B) = sinAcosB + cosAsinB Substituting: [cos(A + B)]^2 + [sin(A...

The 8th term in an arithmetic sequence is 5, and the sum of the first 10 terms is 20. Find the common difference and the first term of the sequence. Alright so in an arithmetic squence the difference d between any two successive numbers is constant. So if the first term is x, ...

Precalculus with applications
f(x)=-4x^2 g(x)=2/x so g(f(x))= 2/(-4x^2)=-1/2x^2 I am wondering why you titled this Precalculus with applications? This problem is certainly content for algebra II. Is someone playing with course names again?

I just realized that the equation that relates x and y to the total length of material should be 2y + 4x = 600. You need 4 fence segments of length x to create 3 areas. Therefore, y = 300 - 2x A = x*(300 - 2x) = 300x - 2x^2 Since dA/dx = 0, 4x = 300 and x = 75. y = 150 Maximum...

Precalculus-------Give an example of three functions f,g,h none of which is a constant function such that? fog=foh but g is not equal to h. I tried with many functions but not getting like f=x g=1+x then h=?or any other example so that we get fog=foh

I have a precalculus test coming up and I'm not really understanding how to do everything. Please help. 1. Find the angle betweem 0 and 2pi which is coterminal to the angle -(7pi)/5. Now convert the angle you just found to degrees.
