The answer is 88 because both numbers are fractions and you need to divide it. So you flip one of the fractions from bottom to top, in this case your next step can be 11/2 multiplied by 16. And then you divied 16 by 2 which is 8. After that you multiply 8 to 11 and that gives you 88 =)
Answer:
B. 
Step-by-step explanation:
The given circle is centered at
and has radius 3 units.
The equation is given by

where (a,b) is the center and r is the radius.
We substitute the values to obtain;


There are a few ways to solve this, the simplest of which is probably factoring. Start by finding factors of C (10) that add up to be B (-2).
fac(10) { -10, 1 ; -5, 2 }
Well, there are no factors of 10 that can add to b - so we will use the quadratic formula.
(-b +- sqrt(b^2 - 4ac)) / 2a
where a = 1, b = -2, c = 10
b^2 - 4ac = (-2)^2 - 4(1)(10) = 4 - 40 = -36
-b +- sqrt(-36) / 2a
(2 +- sqrt(-36)) / 2
sqrt(-36)
sqrt(-1 * 36)
sqrt(-1) * sqrt(36)
i * 6
6i
2 + 6i / 2 ; 1 + 3i
2 - 6i / 2 ; 1 - 3i
Solutions: 1 + 3i, 1 - 3i
