Answer:

H) 2

Step-by-step explanation:

$\frac {\sqrt {1 - \cos^{2}x}}{\sin x} + \frac {\sqrt {1 - \sin^{2}x}}{\cos x}$

= $\frac {\sin x}{\sin x} + \frac {\cos x}{\cos x}$ [since 0 < x < (π/2) and $\sin^{2}x + \cos^{2}x = 1$ ]

= (1 + 1)

= 2

We know that in general,

by $\sqrt {x}$ we mean the positive square root of x only.

Answer:

The number of unsold cakes was 2

Step-by-step explanation:

<u><em>The question in English is</em></u>

In the school Francisco I. Madero of Ciudad Delicias, the celebration was held for commemorate the arrival of spring, after the parade the stalls were set up of the kermesse. The first grade group bought 8 cakes and sold 3/4 of the total.

How much of the cake was not sold?

Let

x ----> number of cakes sold

y ----> number of cakes that didn't sell

we know that

The first grade group bought 8 cakes

$x+y=8$ -----> equation A

The first grade group sold 3/4 of the total.

$x=\frac{3}{4}(x+y)$ ---> equation B

substitute equation A in equation B

$x=\frac{3}{4}(8)=6$

Find the value of y

$6+y=8$

$y=2$

therefore

The number of unsold cakes was 2

So for this, you will be doing two different multiplications: 3 x 4 and √8 x √3.

3 x 4 = 12

√8 x √3 = √24

Now our result is 12√24, however, this can be simplified. Using the product rule of radicals (√ab = √a x √b), our simplification is such:

12√24 = 12√(8 x 3) = 12√(4 x 2 x 3) = 2 x 12√(2 x 3) = 24√6

In short, the answer is 24√6, or the first option.
