Answer:

The square rug. The area of the rug is 39.69 ft² and is 0.33 ft² bigger than the rectangle rug.

Step-by-step explanation:

The find the area of a square, you multiply the length or the width (they all have the same length in a square) by the width (or the length), which would be the same exact number. So in that case—

The square has a side length of 6.3. To find the area of the square, we simply multiply 6.3 · 6.3 =39.69.

So, the area of the square is 30.69 ft²

————————————————————————————————————————

To find the area of a rectangle, you have to multiply the width by the length. (Or vise versa) This is showed by the following formula.

L·W=A

Where L=length, W=width, and A=area.

If the length is 8.2 and the width is 4.8, we can do the multiplicant equation that follows.

8.2·4.8= 39.36 ft².

Now that we have the area of both figures, we can compare them.

The square rug— 39.69

The rectangular rug— 39.36

Of we subtract the areas

39.69 and 39.36, we get the answer that the square rug is bigger by 0.33 ft².

Which of the following represents the zeros of f(x) = x3 − 11x2 + 38x − 40?
Delvig [45]
The answer is <span>5, 4, 2
</span>
Among all choices we have 5, so
x = 5
x - 5 = 0
Let's divide the expression by (x - 5) using the long division:
                          x³ - 11x² + 38x - 40
(x - 5)  * x² =      x³ - 5x²                   Subtract
____________________________
                              -6x² + 38x - 40
   (x - 5) * (-6x) =    -6x² + 30x          Subtract
____________________________
                                           8x - 40
                    (x - 5) * 8 =     8x - 40   Sutract
____________________________
                                              0

Thus: x³ - 11x² + 38x - 40 = (x - 5)(x² - 6x + 8)

Now, let's simplify x² - 6x + 8.

x² - 6x + 8 = x² - 2x - 4x + 8 =
                  = x² - 2*x - (4*x - 4*2) = 
                  = x(x - 2) - 4(x - 2) =
                  = (x - 4)(x - 2)

Hence:
x³ - 11x² + 38x - 40 = (x - 5)(x - 4)(x - 2)
To calculate zero:
x³ - 11x² + 38x - 40 = 0
(x - 5)(x - 4)(x - 2) = 0
x - 5 = 0            or             x - 4 = 0              or      x - 2 = 0
x = 5                 or              x = 4                   or      x = 2

A) Interest = principal * rate * time

I = (800)(0.05)(3) = $120

b) $800 + $120 = $920 after the three years. $920 * (1 - 0.02) = $901.60.
