Solve for x. 2x/3 + 1 = 3 x = 1 x = 6 x = 3 x = 2

4. The cosine function can be made to have the same values as the sine function for each angle by including a shifted _______ in

r-ruslan [8.4K]

Answer: Option D

phase

Step-by-step explanation:

By definition, the cosine function has the following form

$y = cos (x - \phi)$

Where $\phi$ is known as the phase angle

By definition the sinx function is equal to the cosx function with a phase shift of $\frac{\pi}{2}$

So if we have the function

$y = cos (x - \phi)$ and we want to transform it into the function $y=sin(x)$ then $\phi = \frac{\pi}{2}$

Finally

$y = cos(x - \frac{\pi}{2})=sin(x)$

the answer is the option D

How many DVDs. A small independent movie company determines the profit P for producing n DVD copies of a recent release is P = −

Softa [21]

The company should produce "85" DVD's to maximize the profit.

According to the question,

The profit P for producing n DVD copies are

$P=-0.02n^2+3.4n -16$

Let,

The number of units be "n".

Now,

To find the minimize profit,

→ $P'(n) = 0$

→ $-0.04n+3.4=0$

By substracting "3.4" from both the sides, we get

→ $-0.04n+3.4-3.4=-3.4$

→ $-0.04n = -3.4$

→ $n = \frac{-3.4}{-0.04}$

→ $n = 85$

Thus the answer above is right.
