Answer:
The first one is 60 and the second one is 12
Step-by-step explanation:
5*12=60 6*12=72 72-60=12
C. Reflected over the y-axis and translated up 1 unit
Answer:
tgere would be 72 slices.
Step-by-step explanation:
12/1÷1/6
12/1×6/1
72/1
Answer:
180
Step-by-step explanation:
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 !
