Answer: the baby weighs 16.5 pounds
The dot product of the two vectors will be given as follows:
v*w=(-7i+4j)*(-6i+5j)
=(-7*(-6))i+(4*5)j
=-42i+20j
Hence the answer is:
v*w=(-42i+20j)
This is a trick question. First just understand that any number over itself is 1 so

is just

so it is just
2
Answer: 9xy−16.3x−10.2
Step-by-step explanation:
Distribute:
=0.95x+−9+9xy+−18x+(−0.25)(−3x)+(−0.25)(4.8)
=0.95x+−9+9xy+−18x+0.75x+−1.2
Combine Like Terms:
=0.95x+−9+9xy+−18x+0.75x+−1.2
=(9xy)+(0.95x+−18x+0.75x)+(−9+−1.2)
=9xy+−16.3x+−10.2
