We have the following vectors:
u = (a, b)
v = (c, d)
We observe that the vectors form an angle of 90 degrees.
Therefore, the product u.v is equal to zero.
We have then:
u.v = (a, b). (c, d) = 0
u.v = ac + bd = 0
ac = -bd
Answer:
B) ac = -bd
Answer:
Each class donated $300
Step-by-step explanation:
1,792 has to be rounded to 1,800, because the answer is estimated, so 1,800 divided by 6 is 300

They are between the parallel lines and on opposite sides of the transversal
Answer:
600, 150
Step-by-step explanation:
Kyle is x
ken is y
x = 4y
x+y = 750
replace x with 4y
4y + y = 750
5y = 750
y = 150
so ken earned 150
x + 150 = 750
x = 600
so Kyle earned 600
