Given line ax+by=c and point (h, k), the perpendicular line through (h, k) can be written as
b(x-h) -a(y-k) = 0
In order for this to be in standard form, it must be rearranged somewhat, and any common factors removed.
We can start with
20(x-8) -5(y-3) = 0
4x -32 -y +3 = 0
4x -y = 29
The standard-form equation of the desired line through (8, 3) is
4x -y = 29

Answer:
In terms of the class, the dot product represents the weighed class average.
Step-by-step explanation:
The two vectors are:
- The weight of each of the semester's exams.
In decimal:
- The class average on each of the exams
In decimal:
-----------------------
Dot product:
Suppose there are two vectors, u and v
u = (a,b,c)
v = (d,e,f)
There dot product between the vectors u and v is:
u.v = (a,b,c).(d,e,f) = ad + be + cf
------------------
So
In terms of the class, the dot product represents the weighed class average.
Answer:
C) {(3, 4), (3, 5)}
Step-by-step explanation:
We know that,
<em>'Function is a relation in which every element of the domain is mapped to a unique element in the co-domain'.</em>
So, we get that,
<em>In the ordered pair (x,y), the if 'x' is mapped to two values say y and z, then for the relation to be a function, y must be equal to z.</em>
So, according to the options, we see that,
In option C i.e. the relation {(3,4), (3.5)}, we have that, 3 does not have unique image i.e. it is mapped to 4 and 5 both.
Thus, this relation does not satisfy the definition of a function.
So, option C will not represent a function.
