Remember that the radicand (the area under the root sign) must be positive or zero for a radical with an even index (like the square root or fourth root, for example). This is because two numbers squared or to the fourth power, etc. cannot be negative, so there are no real solutions when the radicand is negative. We must restrict the domain of the square-root function.
If the domain has already been restricted to
, we can work backwards to add 11 to both sides. We see that
must be under the radicand, so the answer is
A.
I believe the answer is 25% because 6/24 is 1/4 and 1/4= 25%
The volume is 25.12

- b)
- c)
<h3>
What is the equation of a circle?</h3>
- The equation of a circle of radius r and center
is given by:
Item a:
- Center C(5,2), hence
.
The point at the circumference is A(11,10), hence:
Hence:
Item b:
- Center C(-2,-5), hence
.
The point at the circumference is A(3,-17), hence:
Hence:
Item c:
- Center C(5,-1), hence
.
The point at the circumference is A(-2,-5), hence:
Hence:
