3) After going 4 floors down, we are on level -4. After going 9 floors up to the desired room, we are on level -4+9=5. So the conference center is on floor 5.
Answer:
your answer is incorrect. The correct answer is
and
.
Step-by-step explanation:
If a quadratic function is
and a>0, then minimum value of the function at point
.
The given function is
Here, a=1, b=b and c=182. So.
Put
in the given function to find the minimum value of the function.
We know that minimum value is 13. So,
Taking square root on both sides.
The value of b is 26.
So, the given function is
Now, add and subtract square of half of coefficient of x.
On comparing with
, we get
Therefore, your answer is incorrect.
Answer:
11x + 4d
Step-by-step explanation:
8x + 9d + 3x -5d
To simplify this we have to group them by their like terms i.e.
= 8x + 3x + 9d - 5d
= 11x + 4d

Answer:
Option (3)
Step-by-step explanation:
If binomial (x - 6) and trinomial (-2x² + x + 9) are the factors of a polynomial then their multiplication will be equal to the polynomial.
(x - 6)(-2x² + x + 9) = x(-2x² + x + 9) - 6(-2x² + x + 9)
= -2x³ + x² + 9x + 12x² - 6x - 54
= -2x³ + 13x² + 3x - 54
Therefore, Option (3) will be the correct option.
