A force is specified by the vector F= 160i+80J-120k N. Calculate the angles made by F with positive x,y,z-axis?

I know you would do the sqrt of the whole thing with each one suqared so you end up with |F| = 215.41 Now X = cos^-1 (160/215.41) = 42 degrees what would y and z equal? If i do the same for y but use sin instead of cos, I get 21.80 degrees is that correct? for Z i would use tan?

Which ordered pairs from the replacement set are solutions to the equation? y = -2x + 9 ; Replacement Set {((-1, 11), (0, 8), (1, 7), (2, 5)} (-1, 11) (0, 8) (1, 7) (2, 5) Cartman found these three ordered pairs for the equation y = 54x + 130: {(0, 130), (15, 940), (20, 1210)}. What is the range he will need to use for his y-axis when he graphs it? 0 to 20 0 to 1210 0 to 250 Which of the following best describes the technique used to graph the equation, y = -2x + 8, using slope and y-intercept? Mark a point at 8 on the y-axis, move upward 2 and right 1, mark the point and draw the line. Mark a point at 8 on the y-axis, move downward 2 and right 1, mark the point and draw the line. Mark a point at -2 on the y-axis, move upward 8 and right 1, mark the point and draw the line. Mark a point at -2 on the y-axis, move downward 8 and right 1, mark the point and draw the line. Under water, pressure increases 4.3 pounds per square inch (psi) for every 10 feet you descend. This is represented by the equation p = 0.43d + 14.7, where p is the psi and d is the depth in ft. Find the pressure at 200 feet. 215.13 psi 860 psi 100.7 psi

Answer
*the first one is the (-1,11), (1,7), (2,5) because you just plug in the x and y coordinates so it would be -2(-1)+9=11... 2+9=11... 11=11 and the same thing with the others. *the second one does the same thing... the answer is 0 to 1210 * the third ones answer is: Mark a point at 8 on the y-axis, move downward 2 and right 1, mark the point and draw the line. * the fourth one you plug in too and the answer is 100.7 i know these are right im in honors geometry and ive done this before.. so i hope i helped :)

algebra, your help would be appreciated <33?

Hi, Which of the following best describes the technique used to graph the equation, y = -2x + 8, using slope and y-intercept? a. Mark a point at 8 on the y-axis, move upward 2 and right 1, mark the point and draw the line. (This is y = 2x + 8) b. Mark a point at 8 on the y-axis, move downward 2 and right 1, mark the point and draw the line. <==ANSWER c. Mark a point at -2 on the y-axis, move upward 8 and right 1, mark the point and draw the line. (This is y = 8x - 2.) d. Mark a point at -2 on the y-axis, move downward 8 and right 1, mark the point and draw the line. (This is y = -8x - 2.) Under water, pressure increases 4.3 pounds per square inch (psi) for every 10 feet you descend. This is represented by the equation p = 0.43d + 14.7, where p is the psi and d is the depth in ft. Find the pressure at 200 feet. y = .43d + 14.7 y = .43(200) + 14.7 y = 86 + 14.7 y = 100.7 a. 215.13 psi b. 860 psi c. 100.7 psi <==ANSWER I hope that helps!! :-)
