The basic form of the equation is:
4p(x-h) = (y-k)2
(h,k) is the vertex
4(-0.5)(x-1.5) = (y-(-4))2
-2(x-1.5) = (y+4)2
-2(x-1.5) = y2 + 8y + 16
x - 1.5 = (-1/2)(y2 + 8y + 16)
x = (-1/2)y2 - 4y - 8 + 1.5
x = (-1/2)y2 - 4y - 6.5
<u>Answer</u>
4m
<u>Explanation</u>
Δqrp is a right triangle.
If ps = 6m then, qp = 3m. So we can find line pr using pythagoras theorem.
rp = √(5²-3²) = √16 = 4m
The Δqrp≡Δqtp.
divide total cost by length:
0.76 / 3ft = 0.2533 cents per foot
rounded to nearest cent = 0.25 cents per foot
Remember solving inequalities is setting up two smaller inequalities one positive one negative. Also, when you divide or multiply by a negative number to solve for x the inequality changes over.
