Answer:

<h2>1)</h2><h2>x^{3} - 3timesx -2 = 0</h2><h2>2)</h2><h2>x^{3} - x^{2} - 6timesx</h2>

Step-by-step explanation:

1)

A polynomial function of x can be represented as

f(x) = (x + 1)(x + 1)(x - 2), if we put x = -1 / -1 / 2, then we will get x = 0.

Now,

f(x) = (x + 1)(x + 1)(x - 2) = (x^{2} + 2timesx + 1)(x - 2) = x^{3} + 2timesx^{2} + x - 2timesx^{2} - 4timesx -2 = x^{3} - 3timesx -2.

2)

Similarly, this function must have to be valued 0 for x = -2, 0, 3

Let g(x) be the function.

Hence,

g(x) = (x + 2)(x - 0)(x - 3) = (x^{2} + 2timesx )(x - 3) = x^{3} + 2timesx^{2}  - 3timesx^{2} -6timesx =  x^{3} - x^{2} - 6timesx

NikAS [45]
So my understanding from this you have to make it y = mx + b so m stands for the slope there’s different ways to find it as shown in the first picture. I’ll try to make another comment since this only lets me take one picture at a time.

What is the dimension of a rectangle if the perimeter is 198
AfilCa [17]

Answer:

Length = 49.5 unit and width = 49.5 unit

Step-by-step explanation:

Given as , Perimeter of rectangle = 198 unit

so ,as Perimeter of rectangle = 2× ( Length + width)

Or,                                   198 = 2 ×  (Length + width)

Or,                                   \frac{198}{2} = length + width

So, length + width = 99 unit

Now to make area maximum

Length × width = maximum

Or, (99 - width ) × width = maximum

      99 Width - width² = maximum                              Let width = W

Now differentiate both side with respect to W

D(99W - W²)\frac{D(99w - w^2)}{Dw} = 0         as, constant diff is 0

So, 99 - 2w = 0

Or, w = \frac{99}{2}

Or, w = 49.5 unit    and L = 99- 4905 = 49.5 unit      Answer

IrinaVladis [17]

Answer:

4 rows of 7 plants each

Step-by-step explanation:

To find the number of plants in each row between 5 and 12 requires us to find the factors of the total 28.

28 has factors 1,28 and 2,14 and 4,7. Only 4,7 has a number between 5 and 12. There are 4 rows of 7 plants.
