Answer:
Step-by-step explanation:
If you let b = x^2 the problem becomes a whole lot easier. Note that x = √b
x^2 + x - 12
Now factor this trinomial.
(x + 4)(x - 3)
Now put b back into the equation
(√b + 4)(√b - 3)
You are correct for part A, good job! :D
As for part B, I <em>believe</em> the answers are function, nonlinear, and discrete.
Please let me know if I was wrong at any time. I hope this helps!!
Answer:
3052.08
Step-by-step explanation:
We use the volume formula for spheres
πr³
Plug in 9cm for radius and evaluate
π(9)³
π*729
3052.08
Two angles are complementary when they add up to 90 degrees<span>
m</span>∠B = 90° - m∠A = 90° - 40° = 50°
Two angles are supplementary when they add up to 180 degrees
m∠C = 180° - m∠B = 180° - 50° = 130°
