Answer:
Write a cosine equation with the following properties: Amplitude: 3. Period: 2pi. Midline: 2. Phase shift: 4 units shifted left. In the form of: y=a cos b(x-h) +k.
Answer:
x^4 - 81 = 0
(x² - 9)(x² + 9) = 0
Notice that the first of these is itself a difference of two squares:
(x - 3)(x + 3)(x² + 9) = 0
So the solutions are x = 3, x = -3, x = 3i, x = -3i

Answer:
1149.8 m³
Step-by-step explanation:
The volume (V) of a sphere is calculated as
V = 
πr³ ( r is the radius )
Here diameter = 13, thus radius = 13 ÷ 2 = 6.5
V = × 3.14 × 6.5³
= × 3.14 × 274.625
= 
≈ 1149.8 m³ ( to the nearest tenth )
