Answer:
13
Step-by-step explanation:
g.f=(5)(-1)+(3)(6)=-5+18=13
so inner product=13
it is not zero .Hence they are not perpendicular.

We can write this as
0.6
with a dot above it!
Answer:
x=1
Step-by-step explanation:
6x-14=2-10x
First step is to add 10x to each side
6x+10x-14=2-10x+10x
16x-14=2
Now add 14 to each side
16x-14+14=2+14
16x=16
Divide each side by 16 to isolate x
16x/16 =16/16
x =1
The mapping rule for a 180 degree rotation is:
(x,y) (-x,-y)
1. Multiply the x-coordinate by -1.
2. Multiply the y-coordinate by -1.
3. SImplify
So the coordinate after a 180 degree rotation is: (5,-1)
Answer:
5
Step-by-step explanation:
interior angles of a triangle add up to 180 ⁰ and since it is an isosceles triangle
X=5
