Answer:
2bs + b^2, this is the equation to find the surface area. B is base length and s is slant height.
Step-by-step explanation:
Notice the first two vertices are reverse from each other (a,0) to (0,a)
the fourth vertex would be the reverse of the third one.
The fourth vertex would be (2a, a)
Answer:
7.71
Step-by-step explanation:
The diameter is 3, so the arc length is 180/360 * 3pi or 3pi/2. Now you add the 3 in the base, so it is 3pi/2 + 3 or approximately 7.71 (I used a calculator for that).
To check whether a function is odd or even, we simply substitute the argument by its negative version, namely "x" by "-x".
if the expression simplifies to resemble the original expression, that simply means the expression is
even. If it resembles the original negative expression, is
odd.

well, that doesn't look like the original
- 2x³ - 9, so is not
even.
and -f(x) would be
2x³ + 9, and that doesn't look like either, so is not
odd.
thus is neither.
