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

Which applies the power of a power rule properly to simplify the expression (710)5? (710)5= 710 ÷ 5 = 72 (710)5= 710 - 5 = 75 (7

Sever21 [200]

We are asked in this problem to determine the condensed form of the expression (7^10)^5. we apply here the power rule in which exponents are multiplied to each other to get the expanded form. In this case, we multiply 10 by 5 that is a total of 50. hence the answer to this problem is D. 7^50
