The answer is cos²Ф ⇒ first answer

Step-by-step explanation:

* Lets talk about the trigonometry functions

- sin²Ф + cos²Ф=1 ⇒ subtract cos²Ф from each side

∴ sin²Ф = 1 - cos²Ф

- sin²Ф + cos²Ф=1 ⇒ subtract sin²Ф from each side

∴ cos²Ф = 1 - sin²Ф

- cscФ = 1/sinФ ⇒ cscФ × sinФ = (1/sinФ) × sinФ = 1

* Now lets solve the problem sinФ × cscФ - sin²Ф

∵ sinФ × 1/sinФ = 1

∴ sinФ × cscФ - sin²Ф = 1 - sin²Ф

∵ 1 - sin²Ф = cos²Ф

∴ sinФ × cscФ - sin²Ф = cos²Ф

* The answer is cos²Ф

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
