ANSWER

- \frac{\pi}{4}

EXPLANATION

The given function is,

f(t) = 2 \csc(t + \frac{\pi}{4} ) - 1

This function has a period of
2\pi
just as the parent function

f(t) = \csc(t )

A sample period of this parent function is

[ 0 , 2\pi]

Which begins at zero.

For the transformed function,

f(t) = 2 \csc(t + \frac{\pi}{4} ) - 1
There has been a horizontal shift of
\frac{\pi}{4}
to the left.

The transformed function will have a sample period,

[ - \frac{\pi}{4} , \frac{7\pi}{4} ]

Therefore a sample period begins at

- \frac{\pi}{4}

4 more than the difference of 12 and a number j
Bezzdna [24]

The algebraic expression for the mathematical statement given as 4 more than the difference of 12 and a number j is 4 + 12 - j

<h3>How to determine the arithmetic expression?</h3>

The mathematical statement is given as:

4 more than the difference of 12 and a number j

4 more than means 4 +.

So, we have:

4 + the difference of 12 and a number j

the difference of 12 and a number j means 12 - j

So, we have

4 + 12 - j

Hence, the algebraic expression for the mathematical statement given as 4 more than the difference of 12 and a number j is 4 + 12 - j

Step-by-step explanation:

We can calculate the total cost as follows.  The 1.00 represents the before-tax cost of the dehumidifier and the 0.0575 the 5.75% sales tax:

Total cost of dehumidifier = (1.00+0.0575)($169.99) = $179.76 (to the nearest

How many solutions does the equation 4x + 8 = − 2 − 2 + 5x have?
ikadub [295]

Answer:

12 =x

There is one solution

Step-by-step explanation:

4x + 8 = − 2 − 2 + 5x

Combine like terms

4x+8 = -4+5x

Subtract 4x from each side

4x-4x+8 = -4+5x-4x

8 = -4+x

Add 4 to each side

8+4 = -4+4+x

12 =x
