F(x) = 4x^2+2x+6 what is the discriminant of f? How many distinct real number zeros does f have?

Sunny_sXe [5.5K]

Answer:

The discriminant of f is 92, and it has no real zeros

Step-by-step explanation:

The discriminant of a quadratic is $b^2-4ac$ , where the quadratic is in the form $ax^2+bx+c$ . The discriminant of this one is therefore:

$2^2-4(4)(6)=4-96=-92$

Since the square root of a negative number is imaginary, this quadratic has no real number zeros. Hope this helps!

A website sells a dress at £40 and shoes at £32. The website has an offer: Buy a dress and shoes together and get 1/2 off the pr

tekilochka [14]

Answer:

$\pounds36$

Step-by-step explanation:

Cost of one dress = $\pounds40$

Cost of one pair of shoes = $\pounds32$

Cost of one dress and a pair of shoes is $40+32=\pounds72$

They get half off the price because they buy both

$\dfrac{72}{2}=\pounds32$

The shipping and handling charge is $\pounds4$ .

So, the total amount Ruth has to pay is $32+4=\pounds36$ .
