Write 4 fractions that are equivalent to 6/8.

Talja [164]

Answer:

6/8 is an equivalent fraction of 3/4.

We can find some other equivalent fractions by multiplying the numerator and the denominator of the given fraction by the same number. Thus, the equivalent fractions of 3/4 are 6/8, 9/12, 12/16, and 15/20.

Answer:

<h2><em><u>4th</u></em><em><u> </u></em><em><u>option</u></em><em><u>:</u></em><em><u> </u></em><em><u>19</u></em><em><u> </u></em><em><u>units2</u></em><em><u> </u></em></h2>

Step-by-step explanation:

<h3>The given figure can be divided as (i) upper rectangle, (ii) lower rectangle </h3>

<em><u>Then</u></em><em><u>,</u></em>

(i) Breadth of upper rectangle = 2 units

Length of upper rectangle = 8 - 1 = 7 units

<em><u>Therefore</u></em><em><u>, </u></em>

Area of the upper rectangle = 7 × 2 = 14 units2

(ii) Breadth of lower rectangle = 1 unit

Length of lower rectangle = 5 units

<em><u>Therefore</u></em><em><u>, </u></em>

Area of the lower rectangle = 5 × 1 = 5 units2

<em><u>Since</u></em><em><u>,</u></em>

Area of the figure is = <em>Area</em><em> </em><em>of</em><em> </em><em>upper</em><em> </em><em>rectangle</em><em> </em><em>+</em><em> </em><em>Area</em><em> </em><em>of</em><em> </em><em>lower</em><em> </em><em>rectangle</em><em> </em>

= 14 units2 + 5 units2

= <em><u>19 units2 (Ans) (4th option)</u></em>

Explain why sin^-1(sin(3pi/4))does not equal 3pi/4 when y=sin x and y=sin^-1 x are inverses.

Fofino [41]

Because they're not inverses, not exactly. $\sin x$ is not invertible on its entire domain because it's not one-to-one. There are infinitely many values of $x$ such that $\sin x=0$ , for example.

The standard function $\sin^{-1}x$ has a domain of $-1\le x\le1$ and outputs values between $-\dfrac\pi2$ and $\dfrac\pi2$ . This means that its inverse, $\sin x$ , is indeed its inverse as long as $-\dfrac\pi2\le x\le\dfrac\pi2$ .

$\dfrac{3\pi}4$ is larger than $\dfrac\pi2$ and thus does not fall in the "invertible part" of the domain of $\sin x$ . We have

$\sin\dfrac{3\pi}4=\dfrac1{\sqrt2}$

which is a value between -1 and 1, so that

$\sin^{-1}\left(\sin\dfrac{3\pi}4\right)=\sin^{-1}\left(\dfrac1{\sqrt2}\right)=\dfrac\pi4$

If we wanted to recover $\dfrac{3\pi}4$ , we'd have to redefine $\sin^{-1}x$ or define a new inverse function that works on a different branch of the domain of $\sin x$ .
