Answer: A
Step-by-step explanation:
To find the inner product of two vectors (a,b) and (c,d) you would use the equation (a * c) + (b * d)
So for (7,2) and (0,-2) the inner product would be
(7 * 0) + (2 * -2)
= 4
The vectors are only perpendicular when the inner product is equal to 0. Since it is equal to -4 in this case, the vectors are not perpendicular.
A -4; no
Answer:
z = 4/5
Step-by-step explanation:
3(5z + 7) = 33
Divide each side by 3
3/3(5z + 7) = 33/3
5z+7 = 11
Subtract 7 from each side
5z+7-7 = 11-7
5z = 4
Divide by 5
5z/5 = 4/5
z = 4/5
Answer:
10 centimeter=92 milimeter
Step-by-step explanation:
we know that
one centimeter contains 10 milimeter or
1 centimeter is equal to 10 milimeter
1 centimeter=10 milimeter
we have to find
how many milimetersare there in 9.2 milimeters
9.2 centimeter=? milimeter
for this we will multiply by 9.2 on both sides
1 centimeter=10 milimeter
9.2 centimeter=10*(9.2)=92 milimeter
10 centimeter=92 milimeter
