Answer:
Both A and B
Step-by-step explanation:
A set of ordered pairs is not a function if there is a repeating output (Y value.)
Y values of A= 5, 2, -2, -5.
Y values of B= 2, -2, 4, -3.
There are no repeating outputs.
Answer:
Step-by-step explanation:
The volume of a cylinder can be determined using the formula V = Bh where B is the area of the base of the cylinder and h is the height.
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
In the real world, calculating volume is probably not something that you will use as often as calculating area.
However it can still be important. Being able to calculate volume will enable you to, for example, work out how much packing space you have when moving house, how much office space you need, or how much jam you can fit into a jar.
It can also be useful for understanding what the media mean when they talk about the capacity of a dam or the flow of a river.
The first 3 are correct but for the last one I’m not sure
2(4z-9-11)=166-46
8z-18-22=120
8z-40=120
Add 40 from both side
8z-40+40=120+40
8z=160
Divided 8 from both side
8z/8=160/8
z=20. Hope it help!
