Find s10 for (-1) + (-7) + (-13) + (-19) + a. 250 b. -280 c. (-23) d. 132

the answer is stop cheating on things stoopid

step-by-step explanation:

im eatin up the 44

faster, im not sure why but i know it is faster

a≈380.13mi² would be your answer if the radius was 11 miles

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
