Answer: 0.88 (the 8 recurs)

Step-by-step explanation:

\frac{4}{9}÷\frac{1}{2}

\frac{4}{9}×\frac{2}{1}  (Then the the fraction should reciprocal so the values should shift to          the opposite side were 2 goes up and 1 goes down and the sign turns to the multiplication sign)

then u should multiply the two fractions which gives 8/9

next you should divide 8 by 9 which gives 0.88(the number eight is recurring which means that the number 8 keeps repeating no matter how many times you try to divide)

{\qquad\qquad\huge\underline{{\sf Answer}}}

Let's solve ~

Equation of directrix is : y = 1, so we can say that it's a parabola of form : -

\qquad \sf  \dashrightarrow \: (x - h) {}^{2}  = 4a(y - k)

  • h = x - coordinate of focus = -4

  • k = y - coordinate of focus = 5

  • a = half the perpendicular distance between directrix and focus = 1/2(5 - 1) = 1/2(4) = 2

and since the focus is above the directrix, it's a parabola with upward opening.

\qquad \sf  \dashrightarrow \: (x - ( - 4)) {}^{2}  = 4(2)(y - 5)

\qquad \sf  \dashrightarrow \: (x  + 4) {}^{2}  = 8(y - 5)

\qquad \sf  \dashrightarrow \:  {x}^{2}  + 8x + 16 = 8y - 40

\qquad \sf  \dashrightarrow \: 8y =  {x}^{2}  + 8x + 56

\qquad \sf  \dashrightarrow \: y =  \cfrac{1}{8} {x}^{2}   + x + 7
