The coordinates of the vertices of △abc are a(-2,2), b(5,-3), and c(-4,-1). identify the perimeter of △abc. round each side length to the nearest tenth before adding.

The distance from (-2,2) to (5,-3) is 8.6,  

(5,-3) to (-4,-1) is 9.2

(-4,-1) to (-2,2) is 3.6

add them all together to get the perimeter  

8.6+9.2+3.6= 21.4

so the perimeter is 21.4

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
