Answer:
the answer is
Step-by-step explanation:
1= A(3, 2) B (1, -1) C(4, -2)
2= A(3, 8) B(1, 5) C(4, 4)
3= A(3, -4) B(1, -7) C(4, -8)
4= A(7, 2) B(5, -1) C(8, -2)
5= A(-1, 2) B(-3, -1) C(0, -2)
Answer:
2x-8
Step-by-step explanation:
From the question the meaning of the expression is
Let the number be x
2x - 8

Answer:
Part A:
The surface area of a cylinder is given by
A= 6πr² if h= 2r
Part B:
Total Cost of covering the cylinder = Rate *2πrh + rate*2πr²
Cost of covering only the side = Rate *2πrh
Step-by-step explanation:
Part A:
The surface area of a cylinder is given by
A= 2πrh + 2πr²
Where h= height and radius = r
But we have the height twice as radius so h= 2r
So putting h= 2r we get
A= 2πr(2r) + 2πr²
A= 4πr² + 2πr²= 2πr²(2+1) = 2πr²(3)= 6πr²
Part B:
Cost = Rate * area of the wall + rate * area of the top and bottom
Cost = Rate *2πrh + rate*2πr²
Where area of the top and bottom= πr² +πr² =2 πr²
and area of the side = 2πrh
Multiplying both with the rate and then adding would give the total cost of materials needed to cover the outside of the cylinder and from top and bottom as well.
If you do not need to cover top and bottom then the expression would be
Cost of covering only the side = Rate *2πrh
Part C:
Already done above.
Answer:
Step-by-step explanation:
irdk maf is hard am i right
B) should be your answer
The first one (the one given), is 6 "points" (forgot what it's called sorry) from 0 on all sides. To dilate it 1/3, divide 6 and 3
6/3 = 2
The one's that have points that land on points with 2 in it is B
so B is your best answer
hope this helps
