Answer:

-\cos nw_0t

Step-by-step explanation:

We can use the double angle identity for sine.

\sin (A+B)=\sin A \cos B+\sin B\cos A

The given expresion is

\sin (nw_0t-90)

We apply the identity to get:

\sin (nw_0t-90)=\sin nw_0t \cos 90-\cos nw_0t \sin 90

We simplify to obtain;

\sin (nw_0t-90)=\sin nw_0t (0)-\cos nw_0t (1)

This simplifies to:

\sin (nw_0t-90)=-\cos nw_0t The correct answer is D

Sarah is paid biweekly. Her annual salary is $33,000.
bezimeni [28]

Answer:

$1269.23

Step-by-step explanation:

Since Sarah is paid biweekly (every 2 weeks), and there are 52 weeks in a year...

52 ÷ 2=26

Sarah is being paid 26 weeks out of the year.

Divide 33,000 by 26 (I only list 4 places after the decimal):

33000 ÷ 26=1269.2307

Round 1269.2307 to the nearest cent (hundredth):

1269.23

Compare the two functions in the table. Will the value of function y = 2x eventually exceed the value of function y = x10?
Andrew [12]
First we rewrite the functions:
 y = 2x
 y = x ^ 10
We note that the second function always has values of y greater than the first function. However, there is a value of x for which the first function is greater.
 For x = 1 we have:
 y = 2 (1) = 2
 y = (1) ^ 10 = 1
 We note that:
 2> 1
 Answer: 
 Yes, the value of function y = 2x eventually exceed the value of function y = x ^ 10.
