Cancel the common factor of the numerator and the denominator and write specified expression

lisabon 2012 [21]

Step-by-step explanation:

Hello,

I hope you mean to cancel the common factor that exists in numerator and denominator,right.

so, Let's look for the common factor, 

here, the expression is, 

=4(x-2)/ (x+5)(x-2)

so, here we find the common factor is (x-2)

now, we have to cancel it. And after cancelling we get,

=4/(x+5)

Note:{ we cancel the common factor if the common factors are in multiply form.}

Hope it helps

PLEASE HELP ASAP!!! WILL GIVE BRAINLIEST!!!

Natasha_Volkova [10]

Answer:

put 0 in y<=2x+4

y<=4

so if y=4, then y<=2x+4 is true, but y can not equal 4 because they don't want y<2x+4 be true. So y should be 3, 2, 1, 0.

(0, 2)

put -2 in y<=2x+4

y<=0

so if y=0, then y<=2x+4 is true, but y can not equal 0 because they don't want y<2x+4 be true. So y should be negative.

(-2, -1)

suppose for an angle theta in a right triangle cos theta = C. Sketch and label this triangle, and then use it to write the other

VARVARA [1.3K]

Answer:

$sin\theta = \sqrt{1-C^2}$

$tan\theta = \dfrac{\sqrt{1-C^2}}{C}$

$cot\theta = \dfrac{C}{\sqrt{1-C^2}}$

$sec\theta = \dfrac{1}{C}}$

$cosec\theta = \dfrac{1}{\sqrt{1-C^2}}$

Step-by-step explanation:

Given that:

$\theta$ is an angle in a right angled triangle.

and $cos\theta = C$

To find:

To draw the triangle and write other five trigonometric functions in terms of C.

Solution:

We know that cosine of an angle is given by the formula:

$cosx =\dfrac{Base}{Hypotenuse}$

Here, we are given that $cos\theta = C$ OR

$cos\theta = \dfrac{C}{1}$

i.e. Base = C and Hypotenuse of triangle = 1

Please refer to the right angled triangle as per given statements.

$\triangle PQR$ , with base PR = C units

and hypotenuse, QP = 1 unit

$\angle R$ is the right angle.

Let us use pythagorean theorem to find the value of perpendicular.

According to pythagorean theorem:

$\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}$

$1^{2} = C^{2} + QR^{2}\\\Rightarrow QR = \sqrt {1-C^2}$

$sin\theta = \dfrac{Perpendicular}{Hypotenuse}\\\Rightarrow sin\theta = \dfrac{\sqrt{1-C^2}}{1}\\\Rightarrow sin\theta = \sqrt{1-C^2}$

$tan\theta = \dfrac{Perpendicular}{Base}\\\Rightarrow tan\theta = \dfrac{\sqrt{1-C^2}}{C}$

$cot\theta = \dfrac{Base}{Perpendicular}\\\Rightarrow cot\theta = \dfrac{C}{\sqrt{1-C^2}}$

$sec\theta = \dfrac{Hypotenuse}{Base}\\\Rightarrow sec\theta = \dfrac{1}{C}}$

$cosec\theta = \dfrac{Hypotenuse}{Perpendicular}\\\Rightarrow cosec\theta = \dfrac{1}{\sqrt{1-C^2}}$

0.138 into a decimal

Andru [333]

Step-by-step explanation:

13.8% = 0.138 in decimal form.

Percent means 'per 100'. So, 13.8% means 13.8 per 100 or simply 13.8/100.

If you divide 13.8 by 100, you'll get 0.138 (a decimal number). Read more below on this webpage.

As you can see, to convert from percent to decimal just divide the percent value (13.8) by 100, and remove the "%" sign.
