Answer:
The answer would be 100^32
If the discriminant, b^2 — 4ac is positive (or > 0), then the solution will be two (2) distinct real solutions.
If the discriminant is positive ( > 0), there are 2 real solutions.
If the discriminant is = 0, there is 1 real repeated solution.
If the discriminant is negative (< 0), there are 2 complex solutions (but no real solutions).
Answer:
726 children
242 adults
Step-by-step explanation:
a + c = 968
6c + 11a = 7018
Use Substitution: c = 968-a
6(968-a) + 11a = 7018
5808 - 6a + 11a = 7018
5a = 1210
a = 242
c = 968 - 242 = 726
Answer:
which agrees with answer A
Step-by-step explanation:
Notice there are three right angle triangles for which we can apply the Pythagorean theorem:
In the small triangle at the bottom we have the Pythagorean theorem rendering:
(a)
in the second right angle triangle on top of the previous one, if we call the vertical side on the right side "z", we have:
(b)
and finally in the large right angle triangle:
(c)
We can combine equations b and c to obtain:
and then combine this and (a) to get:
