Answer:
(b) 1272
Step-by-step explanation:
The volume of a cone is found using the formula V=
So plug in each variable according to the image.
The radius is 9 and the height is 15, so plug those in and multiply out the answer. You were also told to use 3.14 for pi so plug that in aswell.
(3.14)(9*9)(15/3)
(3.14)(81)(5)
= 1271.7
= 1272

Answer:
g(x) is a quadratic function ⇒ 2
Step-by-step explanation:
- The quadratic function is the function that has 2 as the greatest power of the variable
- The form of the quadratic function is f(x) = ax² + bx + c, where a, b, and c are constant
Let us use the information above to solve the question
∵ f(x) =
∵ x is the exponent of the base 1.5
→ That means f(x) is not in the form of the quadratic function
∴ f(x) is not in the form of the quadratic function above
∴ f(x) does not represent a quadratic function
∴ f(x) is not a quadratic function
∵ g(x) = 500x² + 345x
∴ The greatest power of x is 2
→ That means g(x) is in the form of the quadratic function above
∵ g(x) is in the form of the quadratic function above, where a = 500,
b = 345, and c = 0 (constant values)
∴ g(x) represents a quadratic function
∴ g(x) is a quadratic function
