Answer:
b)0, yes
Step-by-step explanation:
Given:
Vectors (4,8) . (6,-3)
Finding inner product of vectors:
= 4x6 + 8x-3
=24-24
=0
Now to check the angle between them using formula a.b=|a|.|b|cosθ
|a|=
=8.9
|b|=
=6.7
Putting values of a.b=0 and |a|=8.9, |b|=6.7 in a.b=|a|.|b|cosθ we get,
0= 8.9(6.7)cosθ
cosθ =0
θ=90 degrees
Hence the two vectors are perpendicular !
These two should be the points as then 2 points will remain on both sides
Slope
Equation in point slope form
- y+2=3/4(x+6)
- y=3/4x+6-2
- y=3/4x+4
When x=-15
- y=3/4(-15)+4
- y=-45/4+4
- y=(-45+16)/4
- y=--29/4
Just above 7
Answer:
Step-by-step explanation:
Fist we multiply the values:
2*4y-2*1=6
8y-2=6
8y=6+2
8y=8
y=8:8
y=1
Answer: B) FG
In geometry, a branch of mathematics, perpendicular lines are defined as two lines that meet or intersect each other at right angles (90°).

Answer: 3 × 1/ 10 is not less than 3 × 10
Step-by-step explanation:
Because 3 × 1 / 10 is (0. 3) and 3 × 10 is (30) they are equivalent.
