If 1-cosA=1/2 then prove that Tan^2 A+4sin^2=6.​

i believe the answer is d.

hope it you! : d

make sure you have version 2.50

try looking in the very back of the book : )

step-by-step explanation:

you can download it here

there is nothing below so i cannot

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
