Answer:

$-\frac{8496}{25}$

Step-by-step explanation:

$177\cdot -1.92 = -177-(1.77*92)=-177-162.84=-339.84=\dfrac{33984}{100}=-\frac{8496}{25}$

1. Draw the graph of f(x) = cos x for 0 I know how to construct the graph but I don’t know how to get the figures. Please help

Answer:

Please refer to the attached figure.

Step-by-step explanation:

Given the function:

$f(x) =cosx \ where\ \{0^\circ\leq x\leq 360^\circ\}$

OR, the given function can also be written as:

$y = f(x) = cosx$

We know that graph of cosine is a wave.

and the range of cosine function is [-1, 1]

First of all, let us have a table of values at major values of x.

$x = 0, f(x) = 1\\x = 90, f(x) = 0\\x = 180, f(x) = -1\\x = 270, f(x) = 0\\x = 360, f(x) = 1$

So, the table of values for f(x) is:

$\begin{center}\begin{tabular}{ c c }x & cosx \\0 & 1 \\90 & 0\\180 & -1\\270 & 0\\360 & 1\\\end{tabular}\end{center}$

Let us mark these points on the xy coordinate axis where x axis represents value of x and y axis represents value of $f(x) = cosx$ and then join the points using a wave.

-3x-5<10 Equations

Andrew [12]

Answer:

x>-5

Step-by-step explanation:

First, we need to isolate the variable. To start doing this we can add five to both sides. We now have -3x<15. We then have to divde by -3. When working with inequalites you flip the inequality sign when dividing by a negative number. That then leaves us without answer, x>-5.

Calculate the pay for the following day of a

USPshnik [31]

Answer: $122.50

Step-by-step explanation:

In Out

8:00 12:00 = 4 hours

12:45 17:30 = 4.75 hours

Total 8.75 hours

8.75 hours x $14/hr = $122.50

Note: to subtract 12:45 from 17:30, borrow 1 hour from 17 and add 60 minutes to 30:

17:30 → 16:90

- 12:45 - 12:45

4: 45

4 hours 45 minutes = $4\frac{3}{4}$ = 4.75 hours
