Answer:
3.5, 4.2
Step-by-step explanation:
reflect make it not negative and its on y axis so y not affected
First we write the kinematics equations:
a
v = a * t + vo
r = a * (t ^ 2/2) + vo * t + ro
For Wanda we have: a = 0
v = 5
r = 5 * t
For Dave we have: v = 10
r = 10 * (t-120)
To solve the system of equations, we graph both functions and see where
they intersect.
We have to intersect in the ordered pair:
(t, r) = (240, 1200)
answer If they continue walking at these rates, Dave catch up to Wanda in 240s (1200 ft)

The answer A. Census
Census is a survey of <em>every member of a given population</em>. This means that the respondents include all members of the group that you want to study. For example, you want to do a study on the preferred restaurant of the students of a particular school. If you will do a census, you need to get the response of each student in that school.
