Step-by-step explanation: We are given to find the value of x from the following trigonometric equation:
sin55=cosx
We know that the sine of any acute angle is equal to the cosine of its complement and cosine of any acute angle is equal to the sine of its complement.So, from equation (i), we get
sin55 ∘ =cosx
⇒sin55 ∘ =sin(90 ∘−x)
⇒55 ∘ =90 ∘ −x
⇒x=90 ∘ −55 ∘
⇒x=35 ∘
Thus, the required value of x is 35°.
10 - 9 = y/11
1 = y/11
1 * 11 = y
11 = y
y = 11
0.03113417 is your answer
Answer:
$ 44
Step-by-step explanation:
If we analyze the statement well, we can observe something very crucial to solve it, the jumbo biscuits require 2 oz of flour and give a profit of $ 0.08, the Regular one that only requires 1 oz of flour leaves a profit of $ 0.11, which means that requiring a smaller quantity of flour leaves a greater profit, so in terms of profit it is not profitable to make Jumbo, only Regular.
Therefore, since you can make 400 biscuits, they would all be regular since there are 600 oz of flour available, it is enough to make 400, therefore the maximum profit would be:
$ 0.11 * 400 = 44
The maximum possible profit is $ 44
Answer:
sin(2θ) = 1/2 has 4 solutions instead of 2
Step-by-step explanation:
The argument of the sine function (2θ) will have a possible range of 0 to 4π in the latter equation, doubling the number of possible answers.

The number of cycles of the sine function you need to consider will match the coefficient of the variable in the sine function argument. Perhaps the graph below can give you a clue as to why.
