Step-by-step explanation:
Answer:
• discriminant: 73
• # of real solutions: 2
Step-by-step explanation:
Comparing the equation ...
2x^2 -9x +1 = 0
to the generic form ...
ax^2 +bx +c = 0
we find the coefficient values to be ...
a = 2; b = -9; c = 1
That makes the value of the discriminant, (b^2 -4ac), be ...
(-9)^2 -4(2)(1) = 81 -8 = 73
Since the discriminant is positive, the number of real solutions is 2.
Because 6 is just 3 doubled, and when you double you will get a bigger number while multiplying
Answer:
276 papers
Step-by-step explanation:
Make 230 into 10%=23. Multiply 23 by 2 to get 20%. Add that sum (46) to 230, to get how many more papers you graded this week=276.
