Find dy/dx of y=csc(square root of x)

Vitek1552 [10]

Answer:

$y' = -\dfrac{\cot x \csc x}{2 \sqrt{x}}$

Step-by-step explanation:

y = csc x

y' = -cot x csc x

$y = \csc \sqrt{x}$

$y' = \dfrac{d}{dx} [\csc \sqrt{x}]$

$y' = (-\cot x \csc x) \dfrac{d}{dx} \sqrt{x}$

$y' = (-\cot x \csc x) \dfrac{d}{dx} x^{\frac{1}{2}}$

$y' = (-\cot x \csc x) \dfrac{1}{2} x^{-\frac{1}{2}}$

$y' = -\dfrac{\cot x \csc x}{2 \sqrt{x}}$

Identify the factors of the terms of the expression. <br>3). 5+6a+11b<br>4). 13m-2n

xeze [42]

Answer:

factors are 5, 6, a, 11, b

Step-by-step explanation:

3) 5 + 6a + 11b

<u>Algebraic expressions: 5 + 6a + 11b </u>

Are combinations of numbers, variables, and at least one arithmetic.

<u>Term are: 5, 6a, 11b</u>

Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable(s).

<u>Factors are: 5, 6, a, 11, b </u>

Something which is multiplied by something else. A factor can be a variable, number, a term, or a longer expression.

<u>Coefficient: 6, 11 </u>

The numerical factor of a multiplication expression that contains a variable.

<u>Constant: 5 </u>

A number that cannot change its value.

4). 13m-2n (note: it applies as above)

If tan x = 1.731 then sin x =?

lbvjy [14]

Answer:

0.866

Step-by-step explanation:

If tan x = 1.731 then sin x =

Given data

tan x = 1.731

x= tan^-1 (1.731)

x= 59.98°

x= 60° approx

Aso

sin x=??

substitute

sin 60°= 0.866

Hence the answer is 0.866

A long string with a balloon at the end was tied to the ground. After a breeze came up, the balloon was 55 feet to the right of

Alexxx [7]

Answer:

<em>The slope is 0.55</em>

Step-by-step explanation:

<u>Right Triangles</u>

The string, the ground, and the height of the balloon form a right triangle where the trigonometric ratios are satisfied.

The image below shows the geometric construction. We are required to find the slope the string forms with the ground.

It can be found by using the tangent ratio:

$\displaystyle \tan\theta=\frac{y}{x}$

Substituting y=30 and x=55

$\displaystyle \tan\theta=\frac{30}{55}$

$\displaystyle \tan\theta=0.55$

The slope is 0.55
