Which of the following is a root of P(x)=-2x^3+x^2+4x+4?<br> -1<br> 0<br> 1<br> 2
ziro4ka [17]

Answer:

  2

Step-by-step explanation:

You know 0, 1, and -1 are not roots, because the constant is not 0 and the coefficients don't add to 0, even when negating the ones of odd-degree terms.

When evaluating polynomials by hand, it often works well to write them in "Horner form."

  P(x) = ((-2x +1)x +4)x +4

  P(2) = ((-2·2 +1)2 +4)2 +4 = (-3·2 +4)2 +4 = -2·2 +4

  P(2) = 0

2 is a root of P(x).

I like a graphing calculator for questions like this. It can give an answer instantly. (The equation was pasted directly from the question into the calculator, so the solution took 2 clicks and 2 keystrokes.)

You will take 44+(40/100 * 44) = 44 + 17.6 = $61.60 ($61.60 is going to be the retail price of the lamp).

A circle with radius of 5 cm sits inside a 11 cm * 11 cm rectangle.
Nadusha1986 [10]

Answer:

42.43  cm^{2}

Step-by-step explanation:

Given:

A circle with a radius of 5 cm sits inside a 11 cm x 11 cm rectangle.

Question asked:

What is the area of the shaded region as shown in the figure ?

Solution:

First of all calculate area of circle and then area of rectangle:-

Area\ of\  cirle=\pi r^{2}

                      =\frac{22}{7} \times5\times5\\ \\ =\frac{550}{7}\\  \\=78.571\   cm^{2}\\

<u>As here length an width both are 11 cm, we can say that this is a square.</u>

<u />Area\ of\ square=(Side)^{2}

                         =11\times11=121\ cm^{2}

Now, area of shaded region = Area of square - Area of circle

                                               = 121 - 78.571 = 42.429 cm^{2}

Therefore, the area of the shaded region will be 42.43  cm^{2}
