What is the focus of the parabola given by '-(1)/(4)(y + 2)^2 = (x - 1)'?
o a (-1,2)
b. (1,-2)
c. (0,-2)
d. (0, 2)

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
