Answer:
The measure of the angle between the vectors = Ф = 11.30°
Step-by-step explanation:
Given
Next, find the lengths of the vectors:
u = ⟨2, –3⟩
u = ⟨2, –3⟩
Finally, the angle is given by:
cos (Ф) = 5/√26
Ф = arc cos (cos (Ф)) = arc cos (5 √26) / (26)
Ф = 11.30°
Thus, the measure of the angle between the vectors = Ф = 11.30°
Assume the following:
Brad has been in the soccer team for b years.
Scot has been in the soccer team for s years.
"The number of years that brad has been on the soccer team is 2 less than 5 times the number of years that Scott has"
means: b=5s-2
"in total,the boys have been on the soccer team for 10 years."
means: b+s=10
so we have the equations:
i) b=5s-2
ii) b+s=10
substitute b in ii) with 5s-2, as they are equal, from i
(5s-2)+s=10
5s-2+s=10
6s=12
s=2,
then , from b+s=10, b=8
Answer: Brad has been in the team for 8 years.
8 = 4 + 2c
move 4 to the other side
the sign always changes when moving to the other side
8-4= 4-4+2c
8-4= 2c
4= 2c
divide both sides by 2 to get c by itself
4/2= 2c/2
Cross out 2 and 2 divide by 2 and then becomes 1*1*c= c
c= 4/2
Answer: c= 2
