Answer:
D. -√3/2
Step-by-step explanation:
Remember your unit circle.
Alternatively, you can plug in cos(7π/6) into your calc (Put it in rad mode) and calculate your answer.
Answer:
25
Step-by-step explanation:
90 - 65 = 25
Therefore, x is 25
Thenks and mark me brainliest :))
Answer:
2 sin (2A) cos (2A)^4 + 2cos (2A)
---------------------------------------------------
sin (2A)
Step-by-step explanation:
You're correct, the answer is C.
Given any function of the form

, then the derivative of y with respect to x (

) is written as:

In which

is any constant, this is called the power rule for differentiation.
For this example we have

, first lets get rid of the quotient and write the expression in the form

:

Now we can directly apply the rule stated at the beginning (in which

):

Note that whenever we differentiate a function, we simply "ignore" the constants (we take them out of the derivative).
6/100 • 30 = 1.8
1.8 + 30 = 31.8
Answer is $31.8
