Answer:
k=6
Step-by-step explanation:
The parabola that opens up and passes through (-3,-3) will have equation,
The parabola the opens up a d passes through (-3,3) will have equation:
We want to determine the value of k, for which,
We rewrite g(x) in terms of f(x) to get:
Therefore;
Hence k=6
Answer:
The exact value of its surface area = 144π m²
The exact value of its volume = 288π m³
Step-by-step explanation:
∵ The diameter of the sphere is 12m
∴ The radius of the sphere = 12 ÷ 2 = 6m
∵ The surface area of the sphere = 4πr²
∴ The surface area = 4 × π × 6² = 144π m²
∵ The volume of the sphere = 4/3 πr³
∴ The volume = = 288π m³
