Let's actually find the roots, using the quadratic formula:
<span>p(x)=x^2+x+3 gives us a=1, b=1 and c=3.
-1 plus or minus sqrt(1^2-4(1)(3))
Then x = -----------------------------------------------
2
The discriminant here is negative, so the roots x will be complex:
-1 plus or minus sqrt(-11) -1 plus or minus i*sqrt(11)
x = ---------------------------------- = -------------------------------------
2 2
These are irrational roots; they cannot be expressed as the ratios of integers.</span>
Answer:
33.3%
Step-by-step explanation:
The numbers greater than 6 from the spinner are 7 and 8.
2 numbers out of total 6 numbers.
2/6 = 1/3
= 0.333
= 33.3%
X - 4 +6 -x
x - x = -2
0 = -2
No solution
If you multiply or divide by a positive number the inequality sign DOES NOT CHANGE!
If you multiply or divide by a negative number the inequality sign flips around and becomes the opposite.
Answer:
Step-by-step explanation:
tan (40) = x/12
x = 12*tan(40)
