Complete the synthetic division problem below. What is the quotient in polynomial form?
stellarik [79]
The polynomial would be 2x+5.

We bring down the first number inside the box, 2, unchanged.

    _______
-1|  2   7   5
    _______
      2

Now we multiply that 2 by the number outside, -1:
    _______
-1|  2   7   5
    <u>      -2     
</u>      2

Now we add the two numbers in the middle column:
    ________
-1|   2   7   5
    <u>       -2      </u> 
       2   5

Multiply the 5 we brought down by the -1:
    ________
-1|   2   7   5
    <u>       -2  -5 
</u>       2   5   

Add the numbers in the last column:
    ________
 -1|   2   7   5
     <u>       -2  -5
</u>        2   5   0

The 3 numbers under the box represent the coefficients of x² and x, as well as the constant.  When we finish, we no longer have an x², but start at the next level down, which would be x.  2 would be the coefficient of x and 5 would be the constant, with 0 remainder.

The circumference of a circle is 11 pi inches.
ser-zykov [4K]

9514 1404 393

Answer:

  30.25π square inches

Step-by-step explanation:

You can use the formula for area in terms of circumference:

  A = C²/(4π)

  A = (11π)²/(4π) = (121/4)π = 30.25π . . . square inches

_____

You may be expected to find the radius first:

  C = 2πr   ⇒   r = C/(2π) = 11π/(2π) = 5.5 . . . inches

Then use the area formula:

  A = πr² = π(5.5 in)² = 30.25π in²

A trapezoid has bases of lengths 13 cm and 17 cm. The
Vedmedyk [2.9K]

Answer:

135 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = \frac{1}{2} h(a + b)

where h is the height and a, b the parallel bases

Here h = 9, a = 13 and b = 17 , thus

A = \frac{1}{2} × 9 × (13 + 17)

   = 0.5 × 9 × 30

   = 135 cm²

The following shape is only based on squares, semicircles and quarter circles. Find the Area and Perimeter of the shaded part. A
charle [14.2K]

The perimeter of the shaded region is 8π cm and the area of the shaded region is 32(π - 2) cm² or 36.53 square cm.

<h3>What is a circle?</h3>

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

We have shown a square in which a one-fourth circle is shown and making an ellipse.

The perimeter of the circle = 2πr = 2π(8) = 16π cm

The perimeter of the one-fourth is circle = (16π)/4 = 4π cm

The perimeter of 2 one-fourth circle = 2(4π) = 8π cm

The area of the one-fourth circle = (1/4)πr² = (1/4)π(8)² = 16π square cm

The area of the right-angle triangle = (1/2)(8)(8) = 32 square cm

The area of the shaded region = 2(16π - 32) = 36.53 square cm

or

= 32(π - 2)cm²

Thus, the perimeter of the shaded region is 8π cm and the area of the shaded region is 32(π - 2) cm² or 36.53 square cm.
