Problem 1

The roots are x = 0, x = 2, x = -3

------------------

Explanation:

The term "root" is another way of saying "zeros of a function" or "x intercept".

To find the roots, set each factor equal to zero and solve for x.

x-2 = 0 solves to x = 2, while x+3 = 0 solves to x = -3

Problem 2

Roots are x = 1, 1.) WHat are the real zeros of the function y=x(x-2)(x+3), №18010211, 11.06.2022 14:02 and 1.) WHat are the real zeros of the function y=x(x-2)(x+3), №18010211, 11.06.2022 14:02

------------------

Explanation:

Factor by grouping

x^3 - x^2 + 5x - 5 = 0

(x^3 - x^2) + (5x - 5) = 0

x^2(x - 1) + 5(x - 1) = 0

(x^2 + 5)(x - 1) = 0

x^2 + 5 = 0 solves to the roots 1.) WHat are the real zeros of the function y=x(x-2)(x+3), №18010211, 11.06.2022 14:02 and 1.) WHat are the real zeros of the function y=x(x-2)(x+3), №18010211, 11.06.2022 14:02

x-1 = 0 solves to x = 1

1) Wat are the real zeros of the function y=x(x-2)(x+3):

1.) WHat are the real zeros of the function y=x(x-2)(x+3), №18010211, 11.06.2022 14:02

To find the x-intercept, set y = 0:

x( x -2 ) ( x + 3) = 0

Apply the Zero Product Property:

x - 2 = 0 or x + 3 = 0

x = 2 or x = -3

Find the union of solutions:

x = 0 or x = 2 or x = -3

2) Find all of the solutions of the equation

x^3 -x^2 +5x - 5 = 0

x = 1 or no real solution

Apply grouping:

Factor out --> 1.) WHat are the real zeros of the function y=x(x-2)(x+3), №18010211, 11.06.2022 14:02

Apply zero product property:

x - 1 = 0

Rearrange variables to the left side of the equation--> x=1 or no real solutions.

Problem 2

Roots are x = 1, x = i\sqrt{5} and x = -i\sqrt{5}

------------------

Explanation:

Factor by grouping

x^3 - x^2 + 5x - 5 = 0

(x^3 - x^2) + (5x - 5) = 0

x^2(x - 1) + 5(x - 1) = 0

(x^2 + 5)(x - 1) = 0

x^2 + 5 = 0 solves to the roots x = i\sqrt{5} and x = -i\sqrt{5}

x-1 = 0 solves to x = 1

Note: i = \sqrt{-1}

Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg
