Convert. if necessary, round to the nearest tenth. (recall: 1 in. = 2.54 cm) 16 cm a. 4.5 c. 8.5 b. 6.3 d. 6.9

For this case we have the following measure:

16 cm

We want to convert this value from centimeters to inches.

For this, we use the following conversion factor:

So, by applying the conversion factor we have:

The conversion in inches is given by:

b. 6.3

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
