Y=ax+b, y=cx+d (a≠0, c≠0)
If the two line cross perpendicularly ⇔ ac= -1
So a tangent of the perpendicular line is "-(1/5)".
Then, the equation of the perpendicular line is y=-(1/5)x+a (a is <span> y-intercept</span>).
On the other hand, this equation pass r(1, 3), so
3 = -(1/5) times 1 + a
∴ a=16 / 5
Therefore, y=-(1/5)x+16 /5 is answer.
By the way, I'm Japanese so if you find some mistakes in my English, please let me know.
Well,
1/2 is one way of showing that two teachers are getting the paper equally
And 3/6 is also equal to 1/2
So, 1/2 and 3/6 are the answers
Answer:
27 cubic millimeterse
Step-by-step explanation:
V= lwh
v=3 times 3 times 3
v= 9 times 3
v=27
(sorry if its wrong, its 90% chance im right!)
Answer:
Option D is correct.
Step-by-step explanation:
Let V be the volume of hay in each stack
Given:
Length of the each stack is 
And Jay stores hay in cubic stacks on his farm.
The volume of the cone is.
Now, we substitute value of length of stack in above equation.
Therefore, the volume of hay in each stack is
