The slope of the line would be 3/4
Her tax is $3198.
3.9/100=0.039.
0.039*8200=$3198.
I believe the answer is cos^2 theta. Sec^2 theta on the right side of the equation is the inverse of Cos^2 theta, so multiplying the two together will get you 1. Cos^2 theta * Tan^2 theta = Sin^2 theta, and Cos^2 theta * 1 = Cos^2 theta. This all leads to the third and last step in the picture above.
1. TRUE
2. FALSE, A function can only have one output for each input.
3. FALSE, The X - Axis is always the horizontal plane.
4. TRUE
