Answer:

You use cotx = cosx/sinx.

Step-by-step explanation:

I guess you mean cotx sinx = cosx.

You substitute the identity cotx = cosx / sinx:

cotx sinx = (cosx / sin x) * sin x

The sin x ' s cancel to give cosx.

Which table has greater constant of proportionality?
marissa [1.9K]

The table with greater proportionality is table 3.

<h3>What is constant proportionality?</h3>

The constant of proportionality is the ratio between two directly proportional quantities.

As, the constant proportionality is

k= y/x

For table 1,

k = 1/1 = 2/2 =1

For table 2,

k = 6/1= 12/2 = 2

For table 3,

k = 5/1 = 10/2 = 5

For table 4,

k = 4/1 = 8/2 = 4

Hence, table 3 is with greater proportionality.

y = 2(4) + 1

Y is actually equal to 9 minutes, not twelve.
