Which of the following completes the proof? (6 points)
By the midpoint formula
By definition of congruence
Given
By construction
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:
5+ 4x > 7, x > 1/2
Step-by-step explanation:
A boxplot is a graph that displays the middle 50 percent of a data set, using the minimumvalue, first quartile, median, third quartile, and maximumvalue.
A boxplot is a type of graph that visually displays the middle 50 percent of a data set. It is constructed using the minimum value, first quartile, median, third quartile, and maximum value.
The firstquartile is the median of the lower half of the data, while the third quartile is the median of the upper half.
The whiskers extend from the box to the minimum and maximum values within a certain range. The range can vary, but it's often defined as 1.5 times the IQR. Data points beyond the whiskers are considered outliers and are typically marked individually.
