Find the parametric equations for the line through the point p = (-4, 5, -1) that is perpendicular to the plane -3x+0y-2z=1. use "t" as your variable, t = 0 should correspond to p, and the velocity vector of the line should be the same as the standard normal vector of the plane. x =y =z =(b) at what point q does this line intersect the yz-plane? q =

for a) P(x.y.z)= (-4, 5, -1) + t*(-3,0,-2)

for b) Q (x,y,z) = (-5/2 , 5 , 0)

Step-by-step explanation:

Since the parametric of the line is given by:

P(x.y.z)=P₀ (x₀,y₀,z₀) + t * v(x,y,z) , where P₀ is the point of the line at t=0 and v represents the velocity vector ( a vector parallel to the line)

since the velocity vector is parallel to the line , and thus perpendicular to the plane, it will be equal to the normal vector of the plane.  In our case:

-3*x + 0*y - 2*z = 1 , thus v=(-3,0,-2)

then

P(x.y.z)=P₀ (x₀,y₀,z₀) + t * v(x,y,z) = (-4, 5, -1) + t*(-3,0,-2)

P(x.y.z)= (-4, 5, -1) + t*(-3,0,-2)

for b)  the line intersects the  x-y plane at z=0 , therefore

z= z₀ + t* vz = -1 + (-2)*t = 0  → t = -1/2

x= x₀ + t* vx = -4 + (-3)*(-1/2) = -5/2

y= y₀ + t* vy = 5 + 0*(-1/2) = 5

Q (x,y,z) = (-5/2 , 5 , 0)

the answer is b i just did that

step-by-step explanation:

the most boring ever written

step-by-step explanation:

i am writing something. yes, i plan to make it the most boring thing ever written. i go to the store. a car is parked. many cars are parked or moving. some are blue. some are tan. they have windows. in the store, there are items for sale. these include such things as soap, detergent, magazines, and lettuce. you can enhance your life with these products. soap can be used for bathing, be it in a bathtub or in a shower. apply the soap to your body and rinse. detergent is used to wash clothes. place your dirty clothes into a washing machine and add some detergent as directed on the box. select the appropriate settings on your washing machine and you should be ready to begin. magazines are stapled reading material made with glossy paper, and they cover a wide variety of topics, ranging from news and politics to business and stock market information. some magazines are concerned with more recreational topics, like sports card collecting or different kinds of hairstyles. lettuce is a vegetable.
