Determine the equation of a line passing through (2,1) and perpendicular to the line containing points (2-2) and (4,10)
Aleks04 [339]
(2,-2)(4,10)
slope = (10 - (-2) / (4 - 2) = (10 + 2) / 2 = 12/2 = 6
The slope of the original equation is 6, but we are looking for a perpendicular line, so we need the negative reciprocal slope. All that means is " flip " the slope and change the sign. 6 or 6/1.....flip it...1/6...change the sign....-1/6. So we will need the slope of -1/6.

y = mx + b
slope(m) = -1/6
(2,1)...x = 2 and y = 1
now we sub and find b, the y intercept
1 = -1/6(2) + b
1 = -1/3 + b
1 + 1/3 = b
3/3 + 1/3 = b
4/3 = b

so ur perpendicular equation is : y = -1/6x + 4/3

Cosine is a trigonometric function. The value of cos(x+π), when the value of cos(x)=-(√3)/2 is √3/2. The correct option is A.

<h3>What is a cosine?</h3>

Cosine is the trigonometric function equal to the ratio of the side next to an acute angle to the hypotenuse in a right-angled triangle.

Given the value of cos(x)=-(√3)/2, therefore, the value of x can be written as,

cos(x) = -(√3)/2

(x) = cos⁻¹ [-(√3)/2]

x = 5π/6 = 150°

Now, the value of cos(x+π) will be,

cos(x+π)

= cos[(5π/6)+π]

= cos(11π/6)

= √3 / 2

Hence, the value of cos(x+π), when the value of cos(x)=-(√3)/2 is √3/2.
