10 printers / 35 computers
=(10/35) printers/computer
=(2*5/7*5) printers/computer
=2/7 printers/computers
(or)
=2 printers / 7 computers
For quadratic
.. ax^2 +bx +c = 0
the discriminant is
.. d = b^2 -4ac
You have
.. a = 2
.. b = -5
.. c = 7
so the value of the discriminant for your equation is
.. (-5)^2 -4(2)(7)
.. = 25 -56
.. = -31
Because the discriminant is negative, the roots of the quadratic are complex.
Reasoning: this is the usual interpretation of the sign of the discriminant. It derives from the fact that the square root of the discriminant is part of the roots of the quadratic. That part will be imaginary when the discriminant is negative.
_____
The graph shows there are no real roots.
Answer:
f(x) = 3x2
Step-by-step explanation:
I think the given the scatter plot is missing and it is my attachment for your question.
My answer:
f(x) = 3x2, it is a parabolic pathway. a =3 (positive) so the line is going up.
The other options are straight lines so they are wrong.
To find angle, the equation is:
b+81=180
Answer: Equation is : b + 81° = 180°
9(x) plus 9(5) hope this helps :)
