which of the following is the most appropriate unit to describe the rate at which people are entering a theme park? (2 points)
a- hours per person, because the dependent quantity is the hours
b-hours per person, because the dependent quantity is the people
c-people per hour, because the dependent quantity is the hours
d-people per hour, because the dependent quantity is the people

  D.  People per hour, because the dependent quantity is the people

Step-by-step explanation:

A unit rate is some quantity divided by one unit of another quantity. Often a "rate" is the measure of some quantity per period of time. Here, hours are the period of time, so the usual measure of rate would have hours in the denominator.

Often, too, an independent quantity is multiplied by some factor in order to obtain the value of a dependent quantity. In the case where the factor is "people per hour", multiplying by the independent quantity of hours would give the dependent number of people.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
