Andy and Jim are going to compete in the 100-meter dash against each other. Let A be the time it takes Andy to complete the race, and I be the time it takes Jim to complete the race. Based on previous results, they know
that pa = 11.5 seconds and o A = 1 second. They also know that pj = 10.5 seconds and oj = 0.5
seconds.
Assume that their times are independent. Let D be the difference between their times in a random 100-meter
dash (D = A - J).
Find the mean of D.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

mrb

step-by-step explanation:

i used the pitagoras theoreme

but which class are u may know that first

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
