The quadratic functions shown are written in factored form. The roots of a quadratic function will make the factors equal to 0. Drag each function to show whether it has roots at x=−1 and x=5, roots at x=1 and x=−5, or neither.

Roots x = -1 and x =5

k(x) = (x + 1)(x - 5)

m(x) = 1/2(x + 1 )(2x - 10)

Roots x = 1 and x = -5

n(x) = (3x + 15)(x - 1)

f(x) = (x - 1)(x + 5)

q(x) = (2x - 2)(3x + 15)

Neither

h(x) = 1/2(x + 1)(2x - 20)

Step-by-step explanation:

incomplete question. how do you expect anyone to you when you do not post the question in its entirety?

(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
