For six you can write 1/4 because there is 4 pennies and 1 represents each penny
for number 5 you can put 2/10 because there is 10 coins and 2 quarters
and for number 7 is that Bradley has 10 coins not 9 so it would be 1/10
At max a rotation can be equal to π or 180°
So if it's rotated 110° counterclockwise then it's equal to rotation of supplementary angle clockwise
Supplementary angle=180-110=70°
70° rotation clockwise
Answer:
-13
Step-by-step explanation:
Given are two vectors v and w.
v=(6,7,-3) and
w=(-7,5,2)
We are to find the dot product of v.w
We have
Dot product is obtained by multiplying corresponding pairs and adding them
Here we have
v.w=6(-7)+7(5)-3(2)
=-13
