Answer:
it is orthogonal
Step-by-step explanation:
if you do the dot product.
U dot V = 0
(3 times 0) + (0 times 6 ) = 0
0 + 0 = 0
therefore it is orthogonal.
the dot product says that if u dot v equals zero, then you can say that it is orthogonal.
I can help you with something else ??
Question 1:
The labeled points are points from the drawing are:
A,B,C,D,E
Question 2:
The intersection of the two lines is a point since the necessary condition for the two lines to intersect is that they should be on the same plane, hence they form a point.
Thus the correct answer is: True
Question 3:
The name for a given line is given from the end points that forms the line. Hence given that the two points forming the line is B and P, the correct answer is option C]
Question 4:
There are 5 letters and you use 2 to name the line, so the number of choices will be given by:
5C2=5!/(2!(5-2)!)
=(5×4×3×2×1)/(2×1×3×2×1)
=10
Question 5:
Collinear points are three or more points which lie on the same single straight line. In our case the points are:
T,X,V
Answer:
x = {-0.454, 15.954}
Step-by-step explanation:
we can solve this equation by putting it into the quadratic formula
x = [-b +/- sqrt(b^2 - 4ac)] / 2a
x = [-248 +/- sqrt(248^2 - 4(-16)(116))] / 2(-16)
x = [-248 +/- sqrt(61504 + 7424)] / -32
x = [-248 +/- sqrt(68928)] / -32
x = (-248 +/- 262.541425) / -32
x = (-248 + 262.541425) / -32
x = (-248 - 262.541425) / -32
x = {-0.454419531, 15.9544195}
rounding to the nearest thousandth would make it x = {-0.454, 15.954}
