4. The minute hand of a clock is 10 cm in length and begins by pointing at the
the 7
number 9 on the face of the clock.
a) Draw this clock face and collect data
representing the distance of the tip
of the minute hand above or below
the level of 9 on the face of the clock,
relative to the angle of rotation.
b) Use your data to sketch a graph of the
angle versus the distance above or below
the number 9.
c) How does this graph compare to that of
y = sin e?

step-by-step explanation:

the answer is 89 d

i took the test

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
