(09.04 MC) Jim is designing a seesaw for a children's park. The seesaw should make an
angle of 30° with the ground, and the maximum height to which it should rise is
1.5 meters, as shown below:
1.5 meters
30
What is the maximum length of the seesaw? (6 points)
3.0 meters
3.5 meters
4.0 meters
4.5 meters

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

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x

unlimited solutions.

where are the graphs?
