Find the value of Sin^-1(tan π/4).

zvonat [6]

Answer:

D

Step-by-step explanation:

1. Remind that

$\tan \left(\dfrac{\pi }{4}\right)=1.$

Here you can use trigonometric table to find the value of $\tan\left(\dfrac{\pi}{4}\right)$ , or you can remind that $\dfrac{\pi}{4}=45^{\circ}$ and $\tan45^{\circ}=1$ because special right triangle 45°-45°-90° is isosceles (with congruent oppposite and adjacent legs) and the ratio between the opposite leg and adjacent leg is equal to 1.

2. Now

$\sin^{-1}\left(\tan\left(\dfrac{\pi}{4}\right)\right)=\sin^{-1}1=\dfrac{\pi}{2},$

because

$\sin\dfrac{\pi}{2}=1.$

If the function f(x) has a domain of (g,h) and a range of (j,k), then what is the domain and range of g(x) = m(f(x)] + p?

sertanlavr [38]

Answer:

$Dom\{g(x)\} = Dom\{f(x)\} = (g, h)$ .

$Ran \{g(x)\} = (m\cdot j+p,m\cdot k +p)$

Step-by-step explanation:

From Mathematics we remember that the domain of a functions corresponds to the set of values of the independent variable ( $x$ in this case) so that images exist and the range of a function is the set of images.

In this case, we know the domain and range of $f(x)$ and we must find the domain and range of $g(x)$ .

Domain

The domain of $g(x)$ is the domain of $f(x)$ . That is, $Dom\{g(x)\} = Dom\{f(x)\} = (g, h)$ .

Range

We have to define the bounds of the range of $g(x)$ , given that range $f(x)$ is modified by streching and horizontal translation operations:

Lower bound ( $f(x) = j$ )

$g(x) = m\cdot j +p$

Upper bound ( $f(x) = k$ )

$g(x) = m\cdot k +p$

In consequence, the range of $g(x)$ is $Ran \{g(x)\} = (m\cdot j+p,m\cdot k +p)$

A vender bought an earphone for $1378 and she sold it in order to make a profit of 17. 5% calculate the profit made in cash and

Inessa [10]

The profit he made from selling his hearing aids at a profit of 17% is $234.26.

<h3>How to calculate the profit obtained?</h3>

To calculate the profit obtained, we must calculate how much money is equal to 17% of $1,378.

$1,378 ÷ 100 = $13.78
$13.78 × 17 = $234.26

Based on the above, 17% of $1,378 equals $234.26. On the other hand, to calculate the final sale price of the earphone, we add the initial value plus the value of the profit.

$1,378 + $234.26 = $1,612.26

The weight of 72 books is 9 kg.what is the weight of 80 such books? How many such books would weigh 6kg?

Alex17521 [72]

9 divided by 72 = 0.125
0.125 is the weight of one book
0.125 times 80 = 10kg.
So 80 books weight 10kg.
72 divided by 9 = 8 books make up 1 kg.
8 times 6 =48
