charles and his friends started a community group in 2008 to address problems in their neighborhood and to host civic events. the group began with 40 members, and the number of members changed over time as shown in the graph, where the y-axis represents the number of members and the x-axis represents the number of years since 2008.

which statement is true?

a.

the function indicates that the number of members is increasing at a rate that is constant.

b.

the function indicates that the number of members is increasing at a rate that is not constant.

c.

the function indicates that the number of members is decreasing at a rate that is constant.

d.

the function indicates that the number of members is decreasing at a rate that is not constant.

The true statement is:

B.  

The function indicates that the number of members is increasing at a rate that is not constant.

We could write the data points as is given on the graph as follows:

  x       y

  0      40

  1       50

  2      60

  3      80

  4      100

  5      120

  6      150

  7      190

  8      240

  9      300

  10     370

Hence, the rate of change from x=0 to x=1 is:

Rate of change from x=3 to x=5 is:

Hence, the rate is not constant.

Also we could see that with the increasing value of x the y-value also increases.

                  Hence, option: B is the correct answer.

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
