f(x) = 4x^2+2x+6 What is the value of the discriminant of f? How many distinct real number zeros does f have?
Sauron [17]

Answer:

The value of Discriminant of the function is -92

It has ZERO distinct real number zeros.

Step-by-step explanation:

Given:

f(x)=4x^{2} +2x+6

Which is a Quadratic Equation in the general form of

ax^{2}+bx+c=0

where a,b and c are constants.So on comparing the given equation with general form we get,

a=4\\b=2\\c=6

Formula for discriminant we have

Discriminant=b^{2}-4ac\\ =2^{2}-4(4)(6)\\ =4-96\\=-92

now for zeros  we have

x=\frac{-b+\sqrt{b^{2-4ac} } }{2a} \\or\\x=\frac{-b-\sqrt{b^{2-4ac} } }{2a} \\

on substituting these values we get

x=\frac{-2+\sqrt{-92} }{8}

or

x=\frac{-2-\sqrt{-92} }{8}

the term \sqrt{-92} is imaginary

hence the zeros are not real number

The surface area of a triangular pyramid is 1,936 inches squared. If the dimensions are multiplied by 1/4, what will be the new
rosijanka [135]

Answer:

121 inches squared

Step-by-step explanation:

If the dimensions are multiplied by 1/4, we have that the surface area will by multiplied by (1/4)^2, as the dimensions are in inches and the surface area is in inches squared.

So, If the original surface area is 1936 inches squared, the new surface area will be:

New surface area = 1936 * (1/4)^2 = 1936 / 16 = 121 inches squared.
