3) Vertex: (-7, 0) Axis of Symmetry: x=-7
6) Vertex: (-2, -1) Axis of Symmetry: x=-2
Answer:
Step-by-step explanation:
If you cut the square apart along a diagonal, you'll then have two isosceles triangles. Each such triangle will have 3 sides and 3 angles.
Next time, please type in a more descriptive title for your question.
40,000 cause 4x10 is forty and then add the zeros
Answer:
For this case we know that 
represent the radius, 
the height and the rate given is:
And replacing we got:
And that represent 
Step-by-step explanation:
For a tank similar to a cylinder the volume is given by:
For this case we know that represent the radius, the height and the rate given is:
For this case we want to find the rate of change of the water level when h =6m so then we can derivate the formula for the volume and we got:
And solving for 
we got:
We need to convert the rate given into m^3/min and we got:
And replacing we got:
And that represent

Answer: Choice A) 212 square meters</h3>
========================================================
Explanation:
14.10 has four sig figs. The 0 at the end is significant. This measurement is accurate to the hundredths place. If the author wrote 14.1, then it would be accurate to the tenths place with three sig figs.
15.0 has three sig figs. The 0 is significant. If they wrote 15 or 15. then we'd be dealing with 2 sig figs instead; however they placed the 0 there to tell the reader "this measurement is accurate to the tenths place"
---------------------
Multiply the values given
14.10*15.0 = 211.5
Round that to three sig figs. We pick the smaller sig fig count to round to since we cannot be certain it is accurate to four sig figs. In a sense, we pick the weakest link and use that to determine rounding when it comes to multiplication and division.
This means 211.5 rounds to 212
