Math question plz help me

Minchanka [31]

Answer:

The required equation of the line is:

$y=\frac{1}{4}x-1$

Step-by-step explanation:

Given the equation

$y=-4x+3$

comparing the equation with the slope-intercept form

$y=mx+b$

Here,

m is the slope

y is the intercept

so the slope of the line is -4.

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be: 1/4

Therefore, the point-slope form of the equation of the perpendicular line that also intersects the point (8, 1) is:

$y-y_1=m\left(x-x_1\right)$

$y-1=\frac{1}{4}\left(x-8\right)$

add 1 to both sides

$y-1+1=\frac{1}{4}\left(x-8\right)+1$

$y=\frac{1}{4}x-1$

[calculus] the distance from the point (6, -4) to the circle <img src="https://tex.z-dn.net/?f=x%5E2%2By%5E2-8y%3D0" id="TexForm

Answer:

Option C.

The distance from the point to the circle is 6 units

Step-by-step explanation:

we know that

The distance between the circle and the point will be the difference of the distance of the point from the center of circle and the radius of the circle

step 1

Find the center and radius of the circle

we have

$x^{2} +y^{2}-8y=0$

Convert to radius center form

Complete the square

$x^{2} +(y^{2}-8y+16)=0+16$

Rewrite as perfect squares

$x^{2} +(y-4)^{2}=16$

The center is the point (0,4)

The radius is

$r^{2}=16\\r=4\ units$

step 2

Find the distance of the point from the center of circle

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

(6,-4) and (0,4)

substitute the values

$d=\sqrt{(4+4)^{2}+(0-6)^{2}}$

$d=\sqrt{(8)^{2}+(-6)^{2}}$

$d=\sqrt{100}\ units$

$d=10\ units$

step 3

Find the difference of the distance of the point from the center of circle and the radius of the circle

$10\ units-4\ units=6\ units$

therefore

The distance from the point to the circle is 6 units

see the attached figure to better understand the problem
