Answer:
Step-by-step explanation:
M equals 3.5
Answer:
38.56
Step-by-step explanation:
Parallel slope = 2
This is because the original line has slope 2. Parallel lines have equal slopes.
--------------------------
Perpendicular slope = -1/2
The original slope 2 or 2/1 turns into -1/2 after flipping the fraction and the sign. Note the original slope and perpendicular slope multiply to -1. This is true for any pair of perpendicular lines where neither line is vertical.
When I factor[ 2cos (square) - 5cos -3], I get (2cos + 1)(cos - 3). 2cos + 1 = 0, 2cos = -1, cos = -0.5,. Using inv cos on calculator, I get 120 degree related angle.
Answer:
x=-1, x=3, x=4
Step-by-step explanation:
1. Substitute 0 for f(x)
0=(x+1)(x-3)(x-4)
2. Set each set of parenthesis equal to 0
0=x+1, 0=x-3, 0=x-4
3. Solve for x
x=-1, x=3, x=4
