Find a polynomial equation that has roots of -2 and double root 3
lbvjy [14]

Answer:

x³ + 2x² -3x +6

Step-by-step explanation:

We need to find the polynomial whose roots are ,

  • -2 , √3 and √3.

Say of we have zeroes as , α , β and γ , then the polynomial is ,

=> p(x) = k[ (x - α ) ( x - β) ( x - γ) ]

  • where k is constant. Substituting the respective values , we have ,

=> p(x) = k [ ( x - (-2)) ( x - √3) ( x -√3)]

=> p(x) = k[ (x+2)(x² - 3)]

=> p(x) = k[ x(x² - 3) + 2(x² - 3) ]

=> p(x) = k[ x³ - 3x + 2x² - 6 ]

=> p(x) = k[ x³ + 2x² - 3x - 6 ]

<h3><u>Hence </u><u>the</u><u> </u><u>cubic </u><u>polynomial</u><u> is</u><u> </u><u>x³</u><u> </u><u>+</u><u> </u><u>2</u><u>x</u><u>²</u><u> </u><u>-</u><u> </u><u>3x</u><u> </u><u>+</u><u> </u><u>6</u><u> </u><u>.</u></h3>

each blade on a windmill is in the shape of a triangle with a base of 7 feet and a height of 4 ft if there are four blades on th
Sunny_sXe [5.5K]

The total area of the blades is the area of a triangle multiplied by 4.

We have then:

A = (4) * (1/2) * (b) * (h)

Where,

b: base of the blades

h: height of the blades

Substituting values we have:

A = (4) * (1/2) * (7) * (4)

Doing the calculation we have that the area of the blades is given by:

A = 56 feet ^ 2

Answer:

The total area of the blades is:

A = 56 feet ^ 2
