Answer:

\frac{9}{2}\pi +35

Step-by-step explanation:

The area of trapezoid is given by the formula:

A=\frac{1}{2}(b_1+b_2)h

Where

A is the area

b_1 is base 1

b_2 is base 2, and

h is the height

Looking at the figure, base 1 is the left line which goes from y = 3 to y = 3, so 6 units. Also, base 2 is the right line which goes from y = -3 to y =5, so 8 units.

The height is the horizontal distance in the middle, which goes from x = -2 to x = 3, so 5 units. Hence area of trapezoid is:

A=\frac{1}{2}(b_1+b_2)h\\A=\frac{1}{2}(6+8)*5\\A=35

Now, area of semicircle is:

A=\frac{\pi r^2}{2}

Where

A is the area

r is the radius

Looking at the figure, the diameter (twice radius) goes from y = -3 to y = 3, so 6 units. But radius is half of that, so 3 units. Hence area of semicircle is:

A=\frac{\pi r^2}{2}\\A=\frac{\pi (3)^2}{2}\\A=\frac{9}{2} \pi

Total area of the figure is \frac{9}{2}\pi +35

Use synthetic division to divide (x^3 +12x^2 +48x +26) / (x+4)
deff fn [24]

Answer:

The correct option is C

Step-by-step explanation:

(x^3 +12x^2 +38x +26) / (x+4)

Use the coefficients of dividend.

And the divisor is -4:

Bring down 1 and  multiply it by -4 and add to 12

12-4 = 8

Now multiply 8 by -4 = -32

48-32 = 6

Now multiply 6 by -4 = -24

26-24= R2

                        1     12    38    26

                              -4    -32    -24

                       _______________

                        1      8     6      R2

Thus the correct option is C ....

Can someone answer this please??
anyanavicka [17]

  volume of A = 1728

volume of B = 729  

<span> (1728 / 729) = (a / b)^3  (a = width of A, b = width of B)
  a / b = cube root (1728 / 729)  = 4/3   </span><span> b = 10 (given)
a / 10 = 4/3 </span><span>
  a = 40/3 = 13.33333</span>
 so width of A is 13.33m
