Answer:

C. sin(90° - θ)

Step-by-step explanation:

A trig function of an angle equals the cofunction of the angle's complement.

The cofunction of  cosine is sine, and the complement of θ is 90° - θ.

∴ cosθ = sin(90° - θ)

Answer:  Option 'C' is correct.

Step-by-step explanation:

Since we have given that

\cos \theta

We need to find the correct cofunction identity for it.

Cofunction identities represent the relationship among the trigonometric functions.

The value of trigonometric function of an angle is equal to cofunction of its complement.

As we know that sine is a complement of cosine.

so, it becomes,

\cos \theta=\sin(90^\circ-\theta)

Hence, Option 'C' is correct.

I got this! Basically, the instructions say 12 gallons per 3 minutes. So you plug in the 12/3 to find the ratio of how many gallons per 1 minute.

Step-by-step explanation:

So, for the chart you just mulitply and evauluate

Time (min)           | 2 |  3 |  4 |   5  |   6 |

cricket20 [7]

Answer:

At price 3 and 11, the profit will be $0

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

<em> A certain companies main source of income is a mobile app. The companies annual profit (in millions of dollars) as a function of the app’s price (in dollars) is modeled by P(x)=-2(x-3)(x-11) which app prices will result in $0 annual profit?</em>

My answer:

Given:

  • x is the app price
  • P(x) is the profit earned

If we want to find out the app price that will result in $0 annual profit? It means we need to set the function:

P(x)=-2(x-3)(x-11) = 0

<=> (x-3)(x-11)= 0

<=> x - 3 = 0 or x - 11=0

<=> x = 3 or x = 11

So at price 3 and 11, the profit will be $0

Hope it will find you well.
