Answer:
yes they intersect
point of intersection is (-17.6,38.2,18.6)
Step-by-step explanation:
the direction vector for L2 is given but for L1 it is not given.
Let's first find the direction vector for the L1 as;
from points Q1 and Q2 we can find the direction vector by subtracting there corresponding coordinates (x,y,z) as;
-1-(-2), 5-7, 2-3
direction vector for L1= [1,-2,-1]k
Now the equation for L1 is;
x1=-2+k
y1=7-2k
z1=3-k
direction vector for L2 is =[−6, 3, 6]T
So the equation for the L2 is;
x2=-8-6T
y2=4+3T
z2=9+6T
If these points are intersecting then there x coordinates must be equal, y coordinates must be equal and z coordinates must also be equal as;
x1=x2; y1=y2; z1=z2;
-2+k=-8-6T.......(a)
7-2k=4+3T.......(b)
3-k=9+6T.........(c)
subtracting (a) and (c) we get
-2+k=-8-6T
-( 3-k=9+6T)
______________
-5+2k=-17-12T.......(d)
adding (b) and (d) we get
7-2k=4+3T
-5+2k=-17-12T
______________
-2=13-9T
T=1.6 putting in (a) we get k as;
-2+k=-8-6(1.6)
k=-15.6
putting T and k, if it satisfy the equation then they intersect
(c)=3-(-15.6)=9+6(1.6)
18.6=18.6 satisfied.
thus they intersect each other and their point of intersection is
x=-2-15.6
x=-17.6
y=7-2(-15.6)
y=38.2
z=3-(-15.6)
z=18.6
point of intersection is (-17.6,38.2,18.6)

Answer:
A. 25.
Step-by-step explanation:
We have been given that Garland started the week with an odometer reading of 58,240 miles and a full tank. He ended the week with an odometer reading of 58,615, and he re-filled the tank with 15 gallons of gas.
To find the mileage for Garland's bike we will divide total distance traveled by total used fuel.
Therefore, Garland get a mileage of 25 miles per gallon and option A is the correct choice.
A)all the sides of the shape are added together?
