Answer:
8 cm
Step-by-step explanation:
4+4=8 To get the diameter, double the radius and add them together.
F(g(3))
f(4 * 3^2 + 9)
f(45)
3 * 45 - 1
134
Answer:
10
Step-by-step explanation:
the range is the difference between the biggest and the smallest number
55-45=10
Answer:
-4
Step-by-step explanation:
[√2(cos(3π/4) + i sin(3π/4))]⁴
(√2)⁴ (cos(3π/4) + i sin(3π/4))⁴
4 (cos(3π/4) + i sin(3π/4))⁴
Using De Moivre's Theorem:
4 (cos(4 × 3π/4) + i sin(4 × 3π/4))
4 (cos(3π) + i sin(3π))
3π on the unit circle is the same as π:
4 (cos(π) + i sin(π))
4 (-1 + i (0))
-4
