Answer:

No, Felicia’s answer is not correct.

Step-by-step explanation:

She should have divided by 2, not multiplied. 30 divided by 2 is 15. So 15 of the 50 students in the band are boys.

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

Answer:

0.5x+20=0.25x+30, m=40

Step-by-step explanation:

Blue: y=0.5x+20

Red: y=0.25+30

We’re looking for where the y (cost) is equal, so we can set the two equations to each other:

Isolate x:

0.5x+20=0.25x+30

0.5x+20-20=0.25x+30-20

0.5x=0.25x+10

0.5x-0.25x=0.25x+10-0.25x

0.25x=10

x=40

m= 40
