Which is the graph of f(x) = x2 – 2x + 3?

Vertex: (1, 2)

Focus: (1, 9/4)

Axis of symmetry: x = 1

Directrix: y = 7/4

X/Y coordinates for graph:

    x  = 1     0     1     2     3

    y  = 6    3     2     3     6

Graph:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
