Find the equation of a line perpendicular to y - 12 = 2x – 8 that passes through the point (2, 3). (answer in slope-intercept fo
Alla [95]

Answer:

\displaystyle y=-\frac{1}{2}x+4

Step-by-step explanation:

<u>Equation of a Line</u>

We can find the equation of a line by using two sets of data. It can be a pair of ordered pairs, or the slope and a point, or the slope and the y-intercept, or many other combinations of appropriate data.

We are given a line

y - 12 = 2x -8

And are required to find a line perpendicular to that line. Let's find the slope of the given line. Solving for y

y = 2x +4

The coefficient of the x is the slope

m=2

The slope of the perpendicular line is the negative reciprocal of m, thus

\displaystyle m'=-\frac{1}{2}

We know the second line passes through (2,3). That is enough information to find the second equation:

y-y_o=m'(x-x_o)

\displaystyle y-3=-\frac{1}{2}(x-2)

Operating

\displaystyle y=-\frac{1}{2}(x-2)+3

Simplifying

\displaystyle y=-\frac{1}{2}x+4

That is the equation in slope-intercept form. Intercept: y=4

What is the area of the shaded sector?
gavmur [86]
The area of the shaded sector is one-fourth of the area of the whole circle so:
area = r^2 \pi  \\ area = 6^2 \pi  \\ area = 36 \pi
area of shaded region=  \frac{36 \pi }{4} \\ area = 9
The area of the shaded region is 9pi units^2

Find all exact solutions on the interval 0 ≤ x &lt; 2π.
masya89 [10]

Answer:

View Image

x = π/6, 5π/6, 7π/6, 11π/6

Step-by-step explanation:

The only things you need to know are 2 things:

1.) csc^2(x)=(csc(x))^2   , the exponent of trig functions are written in the middle

2.) csc(x)=\frac{1}{sin(x)}   , csc() is just the inverse of sin()
