Let U be the set of all integers from 1 to 20. Let A = (1, 3, 6, 9, 12, 15, 18} and B = {2, 9, 11, 20). Which choice describes the set {4, 5, 7, 8, 10, 13, 14, 16, 17, 19)?

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

alright well the answers to your question is

2xy/9 hope this have a nice day : )
