Evaluate each expression for the given values of the variables. a) a+b a-14, bm-4, x 3 b) mx +b c) tu 4) for each of the following equations, find the indicated value. given se. pa-p find se when p -0.4 and n 30 (round to four decimal places) given v#m-r2.3 find v when r 2 and h 8 (round to the hundredths place) b)

the equation of the parabola is y2=12x

explanation:

the vertex is midway between the focus ad the directrix

so, the vertex is (0,0)

let p=(x,y) be a point on the parabola.

the distance of p from the directrix is equal to the distance from the focus.

x+3=√(x−3)2+(y−0)2

(x+3)2=(x−3)2+y2

x2+6x+9=x2−6x+9+y2

y2=12x

graph{y^2=12x [-10, 10, -5, 5]}

i just took the quiz, c.) x=1 is the
