Step-by-step explanation:

$(1 + \cos(x) )(1 - \cos(x) )$

$1 - \cos {}^{2} (x)$

$= \sin {}^{2} (x)$

$\frac{1}{ \cot {}^{2} (x) } - \frac{1}{ \cos {}^{2} (x) }$

$\frac{1}{ \frac{ \cos {}^{2} (x) }{ \sin { }^{2} (x) } } - \frac{1}{ \cos {}^{2} (x) }$

$\frac{1}{ \cot {}^{2} (x) } - \frac{ \csc {}^{2} (x) {} }{ \cot {}^{2} (x) }$

$\frac{ - \cot {}^{2} (x) }{ \cot {}^{2} (x) }$

$- 1$

$\sec {}^{2} ( \frac{\pi}{2} - x ) )( \sin {}^{2} (x) - \sin {}^{4} (x))$

$( \csc {}^{2} (x) )( \sin {}^{2} (x) - \sin {}^{4} (x )$

$\csc {}^{2} (x) ( \frac{1}{ \csc {}^{2} (x) } - \frac{1}{ \csc {}^{4} (x) } )$

$1 - \frac{1}{ \csc {}^{2} (x) }$

$1 - \sin {}^{2} (x)$

$\cos {}^{2} (x)$

The height of the cone is 4 cm (approx).

Step-by-step explanation:

Given,

The radius (r) of the cone = 4.96 cm

Volume (V) = 102 cm³

To find the height (h) of the cone.

Formula

The volume of a cone V = $\frac{1}{3}$ πr²h

Now,

According to the problem,

$\frac{1}{3}$ πr²h = 102

or, $\frac{1}{3}$ × $\frac{22}{7}$ ×(4.96)²h= 102

or, h = $\frac{102X7X3}{4.96^{2}X22 }$

or, h = 3.95 = 4 (approx)

so,

Height = 4 cm (approx)

What is 18 & 20 & can you show work please??

irina1246 [14]

18. Make the values have the same denominators.

4 2/3(8/8)= 112/24
5 3/8 (3/3)= 129/24

Add the values

112/24+129/24= 241/24

Simplify the answer

241/24= 10 1/24

The answer for question 10 1/24 ounces.

20. Multiply 1 1/4 by 5. (There are 5 days from Monday through Friday)

1.25(5)= 6 1/4

The answer to question 20 is 6 1/4.

Hope this helps!
