Math - equations of lines
Writing the parametric equations of the given line one x=-21-12t and since we want the x intercept the y=z=0 therefore 8+4t=0 and 14+7t=0 in both case the t value is '-2' repeating the similar procedure to find the y-intercept the value of s=-3 there after how do i fin...
Math - equations of lines
A line has the same x-intercept as [x,y,z]=[-21,8,14]+t[-12,4,7] and the same y-intercept as [x,y,z]=[6,-8,12]+s[2,-5,4]. Write the parametric equation of the line.
Math - vector equation of a parallelogram
Isn't there another way to find the vector equation because they are the correct coordinates sample answers are: [x,y]=[-1,4]+t[1,-1] [x,y]=[-1,4]+t[2,1]
Math - vector equation of a parallelogram
The vertices of a parallelogram are the origin and the points A(-1,4), B(3,6), and C(7,2). Write the vector equations of the lines that make up the sides of the parallelogram
Math - intersection of planes
You are given the following two planes: x+4y-3z-12=0 x+6y-2z-22=0 a) Determine if the planes are parallel b) Fine the line of intersection of the two planes. c) Use the two original equations to determine two other equations that have the same solution as the original two. d) ...
Math - Equations of plane(check)
Consider the plane that contains points A(2,3,1), B(-11,1,2), C(-7,-3,-6). a) Find two vectors that are parallel to the plane. Ans: AC, BC or AB will be parallel to the plane. b) Find two vectors that are perpendicular to the plane. Ans: if i find the normal vector then i can ...
