F(x) =5x^2-20x+3 how to find minimum

(2,-17) should be the minimum.

Step-by-step explanation:

The minimum of a quadratic function occurs at . If a is positive, the minimum value of the function is

occurs at

Find the value of

x = 2

evaluate f(2).

replace the variable x with 2 in the expression.

simplify the result.

The final answer is -17

Use the x and y values to find where the minimum occurs.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
