Given Function : f(x) = -3x² + 3x + 7
To find out the value of f(8) : Substitute 8 in the function in place of x
⇒ f(8) = -3(8)² + 3(8) + 7
⇒ f(8) = -3(64) + 24 + 7
⇒ f(8) = -192 + 24 + 7
⇒ f(8) = -161
Answer with explanation:
There are few number of white ball in 10 boxes.
Total number of Black balls in the box=60
So, we have to write number 60 in such a way that, such that it can be represented as sum of ten different digits.
That is the only way by which we can distinguish between ten boxes.
60 =0 +1+2+3+4+6+8+10+12+14
Place these balls in ten different boxes.
So, by this way we can distinguish between boxes.
The answer is
B.
Consider the fraction

.
Both the numerator and denominator, when by themselves, are irrational.
However, when they are divided, they result in the rational number

.
When

have the same irrational factor, the irrational factor will be cancelled from the fraction and (possibly) leave a rational number.
