(8x4+64x3+3x-28)÷(x-8)
1 answer:
check the picture below.
recall that the division is done with the dividend and divisor sorted in descending order, notice the dividend has a jump from x³ to x, so the x² is missing, but is really there, but it has a coefficient of 0, as you see there in red, so we add any missing terms on either side.

Answer:
Area of red band is
Step-by-step explanation:
We know that area of square =
Please refer to the attached figure, we have to calculate the area of red band.
Required area = Area of square <em>ABCD </em>- Area of <em>purple square </em>
Side of purple square =
So, area of purple square =
<em>ABCD </em>is a square with purple square at the center and there is symmetry in the figure.
So, width of red band towards both the end is 5 inches.
Required area =
Using formula
Hence, Area of red band is
You could set up a ratio:
which then becomes:
which then becomes:
Answer:
Option b is correct
Step-by-step explanation:
In order to check the end behavior of a polynomial function we just check the leading term and its coefficient and the procedure is as follows:
Here we can see that highest exponent of the polynomial function is 4
therefore degree of the polynomial is 4. and therefore is leading term.
because of even degree it will be same from both ends that is either both sides rises or both sides falls. Since number in the front of leading is negative therefore it falls at both ends. that is falls to the left and falls to the right.
therefore option b is correct.
