Answer:
The equation of the plane is .
Step-by-step explanation:
An equation of the plane containing the point with normal vector is
The equation of any plane can be expressed as
This is called the standard form of the equation of a plane.
Given the points
Two vectors in the plane are
A normal vector to the plane is
Thus, an equation of the plane is
We can check our results with the graph of the plane.
Answer:
LK=12
Step-by-step explanation:
From the given figure, HI=7 and LH=9, and we know that
(1)
Now, from ΔKHL, we have
and from ΔOKH,
(2)
Also, ΔIKL is similar to ΔOHL, therefore
Using equation (2), we get
Thus, the value of LK is 12.
Answer:
B
Step-by-step explanation:
B for the first one. We have to eliminate A and C right away because they are asking for a function of t and not p. So, in that case it has to start with p. I didnt choose D because there is no such thing as 0p it is 1p. So I am pretty sure its B for the first one.
Sin 0 = 0
Sin 30 = 1/2
Sin 45 = 1/SR of 2
Sin 60 = SR of 3/2
Sin 90 = 1
