find the equation of the line passing through the points (2,4) and (3,2). find both green and grey box

Leto [7]

Answer:

y = -2x +8

Step-by-step explanation:

The 2-point form of the equation of a line is useful when two points are given.

y = (y2 -y1)/(x2 -x1)(x -x1) +y1

y = (2 -4)/(3 -2)(x -2) +4

y = -2(x -2) +4

y = -2x +8

Given:

In a right angle triangle θ is an acute angle and $\tan\theta =\dfrac{3}{5}$ .

To find:

The value of $\cos \theta$ .

Solution:

In a right angle triangle,

$\tan \theta=\dfrac{Perpendicular}{Base}$

We have,

$\tan\theta =\dfrac{3}{5}$

It means the ratio of perpendicular to base is 3:5. Let 3x be the perpendicular and 5x be the base.

By using Pythagoras theorem,

$Hypotenuse=\sqrt{Perpendicular^2+base^2}$

$Hypotenuse=\sqrt{(3x)^2+(5x)^2}$

$Hypotenuse=\sqrt{9x^2+25x^2}$

$Hypotenuse=\sqrt{34x^2}$

$Hypotenuse=x\sqrt{34}$

In a right angle triangle,

$\cos \theta=\dfrac{Base}{Hypotenuse}$

$\cos \theta=\dfrac{5x}{x\sqrt{34}}$

$\cos \theta=\dfrac{5}{\sqrt{34}}$

Therefore, the value of $\cos \theta$ is $\dfrac{5}{\sqrt{34}}$ .

Which number has the same value as 3 X 1/10?

irakobra [83]

To find the same value as 3 x 1/10 you first have to solve 3 x 1/10

so how to do this is you have to make 3 into a fraction

so to make 3 into a fraction you can put 3 as the numerator and 1 as the denominator

so you multiply
$\frac{3}{1} \times \frac{1}{10} = \frac{3}{10}$
so 3/10 has the same value as 3x1/10

HOPE THIS HELPS!!!
