HELP WHAT IS THE ANSWERS

Temka [501]

Answer: Letter Choice, (B) ====> 4,256 pi cm^2

Step-by-step explanation:

Formula: Surface Area of Cylinder = (2pi ) (r^2 ) + 2pi (r) (h)

Showing Work:

Radius of the Base ===> 28cm

Height =====> 48cm 

(2pi ) (r^2) + 2pi (28)(48)

2 (pi) (r^2) + (circumference) (height)

2( pi) (r^2 + 2)( pi)(r)(h)

2 pi * (2) (r^2 + (2)(r)(h)

2pi * (r^2 + rh)

2(r)(pi)(r + h)

2( 28)(pi)(28 + 48)

56(pi)(76)

4256(pi)^2

Therefore, Your Answer ======> Letter Choice; (B) ======> 4,256pi cm^2

Given P(x) = 2x3 - 11x2 + 18x - 15 is divided by x – 3. Use synthetic division to find the quotient and the remainder.

katrin [286]

You can find the remainder right away by simply plugging in $x=3$ . The polynomial remainder theorem guarantees that the value of $p(3)$ is the remainder upon dividing $p(x)$ by $x-3$ , but I digress...

Synthetic division yields

3   |   2   -11   18   -15
.    |           6   -15     9
- - - - - - - - - - - - - - - - -
.    |   2     -5     3     -6

which translates to

$\dfrac{2x^3-11x^2+18x-15}{x-3}=2x^2-5x+3-\dfrac6{x-3}$

(and note that $p(3)=2(3)^3-11(3)^2+18(3)-15=-6$ , as expected)
