Jennifer made an error converting y=x^2 + 2z +7 to vertex form. In which step sis she make an error? Explain your answer and provide the correct form of the question in vertex form.

C

Step-by-step explanation:

Jennifer completed the square by adding 1.  However, to keep both sides equal, she should have added 1 to both sides:

y + 1 = (x² + 2x + 1) + 7

Or, she should have added 1 and subtracted 1 from the same side.

y = (x² + 2x + 1) + 7 − 1

The correct vertex form of the equation is:

y = (x + 1)² + 6

yes

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
