A polynomial ppp has zeros when x=-2x=−2x, equals, minus, 2, x=\dfrac13x= 3 1 ​ x, equals, start fraction, 1, divided by, 3, end
Veronika [31]

Answer:

Polynomial equation is, p=(x+2)(3x-1)(x-3)=3x^3-4x^2-17x+6

Step-by-step explanation:

Given:

The zeros of the polynomial, p, are  x=-2,\frac{1}{3}, 3.

Therefore,

x= -2\\(x+2)=0

So, (x+2) is a factor of the polynomial.

x=\frac{1}{3}\\3x=1\\3x-1=0

So, (3x-1) is a factor of the polynomial.

x=3\\x-3=0

So, (x-3) is also a factor of the polynomial.

Therefore, a polynomial can be expressed in terms of the product of its factors.

Thus, p=(x+2)(3x-1)(x-3)

Expanding (x+2)\textrm{ and }(3x-1), we get

(x+2)(3x-1)=3x^2-x+6x-2=3x^2+5x-2

Now, expanding (3x^2+5x-2)\textrm{ and }(x-3), we get

(3x^2+5x-2)(x-3)=3x^3-9x^2+5x^2-15x-2x+6=3x^3-4x^2-17x+2

Therefore, the polynomial could be p=(x+2)(3x-1)(x-3)=3x^3-4x^2-17x+6

Find the radius of a circle whose area equals the area of a rectangle that measures 2 ft. by 11 ft. (Use = 22/7) 7/2 ft. √7 ft.
serious [3.7K]
First of all, the two figures are equivalent. Find the area of the rectangle and you'll get the area of the circle

A(r) = A(c) = W*L = 2*11 = 22 ft²

A(c) = πr²

π = 22/7

So

22/7*r² = 22

Multiply both sides for 7/22 to get rid of the fraction.

7/22 * 22/7 * r² = 22 * 7/22

r² = 7

r = √7
