Answer: Choice C. (-1, -5)</h3>
Explanation:
The reflection rule we use is

when we want to reflect over the y axis. The x coordinate flips from positive to negative, or vice versa, while the y coordinate stays the same.
Therefore, 
Answer:
h = 5 cm
Step-by-step explanation:
Given that,
The volume of ice-cream in the cone is half the volume of the cone.
Volume of cone is given by :

r is radius of cone, r = 3 cm
h is height of cone, h = 6 cm
So,

Let
is the volume of icecream in the cone. So,

Let H be the depth of the icecream.
Two triangles formed by the cone and the icecream will be similiar. SO,

So, volume of icecream in the cone is :

or
h = 5 cm
So, the depth of the ice-cream is 5 cm.
Since the cross section is constrained to be perpendicular to the base, the shape of it is constrained to be a ...
Rectangle
_____
That rectangle may be a square, but is not required to be.
Answer:
i cant help with the first one but the others i think i can
- plastic (insulator) -stainless steel (conductor) -silver (conductor) -wood (insulator)
Also radiation could effect the system but changing the conductivity of some of the materials also change change the way the materials accept heat.
Sorry about the first one :)
