Answer:
-3x+8
Step-by-step explanation:
-2x-x+8=
-3x+8
Answer:
(4,1)
Step-by-step explanation:
Reflected over x = -3, new point : (1,4)
Reflected over y=x, new point = (4,1)
Answer:
21
Step-by-step explanation:
3/(x-3) = 8/(2x+6)
or, 3(2x+6) = 8(x-3) ( by cross multiplication)
or, 6x + 18 = 8x - 24
or, 8x - 6x = 24 + 18
or, 2x = 42
or, x = 42/2
=21
So
bowl is a half sphere
cylinder is a cylninder
cone is cone
bowl:
area of circle=4/3 pi times r^3
half bowl=4/3 times 1/2 times pi times r^3=2/3pi r^3
cylinder=height times pi times radius^2
this cylinder=r times pi times r^2=pi times r^3
cone=1/3 times height times pi times radius^2
thgis cone=1/3 times r tiimes pi times r^2=1/3 times pi times r^3
compare
bowl=2/3 pi r^3
cylinder=pi r^3
cone=1/3 pi r^3
the cylinder is biggest
CYLINDER IS THE ANSWER
2.
sphwere=4/3 times radius^3 times pi
this sphere=4/3 times pi times r^3
cylinder=height times radius^2 time pi
this cylinder=2r times r^2 times pi=2r^3 times pi
cone=1/3 times height time r^2 times pi
this cone=1/3 times 2r times r^2 times pi=1/3 times 2r^3 times pi=2/3 times r^3 times pi
sphere:4/3 pi r^3
cylinder: 2 pi r^3
cone: 2/3 pi r^3
Answer: 69
Step-by-step explanation: Sorry I do not know the answer because I am not smart. I just need the points so I can answer more questions. Have a great day though and I wish you luck with your question:)
