Complete the point-slope equation of the line through (3,6)(3,6)left parenthesis, 3, comma, 6, right parenthesis and (5,-8)(5,−8

ArbitrLikvidat [17]

Answer:

The required equation of line in point-slope form is:

$y-6 = -7(x-3)$

Step-by-step explanation:

Given points are:

(x1,y1) = (3,6)

(x2,y2) = (5,-8)

The point-slope form of an equation is given by:

$y-y_1 = m(x-x_1)$

Here m is slope of the line and (x1,y1) is a point on line

The slope is calculated using the formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Putting the values we get

$m = \frac{-8-6}{5-3}\\m=\frac{-14}{2}\\m= -7$

Putting in the equation

$y-y_1 = -7(x-x_1)$

Now we have to put a point in the equation, putting (3,6) in the equation

$y-6 = -7(x-3)$

Hence,

The required equation of line in point-slope form is:

$y-6 = -7(x-3)$

Let L be the line parametrized by x = 2 + 2t, y = 3t, z = −1 − t. (a) Find a linear equation for the plane that is perpendicular

Elden [556K]

Answer:

Step-by-step explanation:

Given that L is a line parametrized by

$x = 2 + 2t, y = 3t, z = −1 − t$

The plane perpendicular to the line will have normal as this line and hence direction ratios of normal would be coefficient of t in x,y,z

i.e. (2,3,-1)

So equation of the plane would be of the form

$2x+3y-z =K$

Use the fact that the plane passes through (2,0,-1) and hence this point will satisfy this equation.

$2(2)+3(0)-(-1) =K\\K =5$

So equation is

$2x+3y-z =5$

b) Substitute general point of L in the plane to find the intersecting point

$2(2+2t)+3t-(-1-t) =5\\4+8t+1=5\\8t=0\\t=0\\(x,y,z) = (2,0,-1)$

i.e. same point given.

a rectangular section of land has a length of 5•10^3 meters and a width of 6•10^2 meters. what is the area of land in square met

monitta

A = lw
A = (5 × 10^3)(6 × 10^2)
= 5000 × 600
= 300000
= 3 × 10^6 m^2
