Write the equation of the parabola in standard form and find the vertex of its graph.

y=x^2+10x+16

a: y=(x+5)^2-9; vertex: (5,-41)
b: y=(x-5)^2+11; vertex: (5,41)
c: y=(x+8)(x+2); vertex: (10,16)
d: y=(x+5)^2-9; vertex: (-5,-9)
e: y=(x+5)^2+41; vertex: (-5, 41)

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
