The polynomial function of least degree with leading coefficient 1 and having zero at the given points is, [tex]f(x) = x^3-3x^2+\sqrt{5}x^2 +2x-\sqrt{5} x[/tex].

What is polynomial?

A polynomial is an expression in mathematics that solely uses the operations of addition, subtraction, multiplication, and powers of positive-integer variables. It consists of indeterminates and coefficients. The polynomial x^2 + 4x + 7 is an illustration of one with a single indeterminate x.

From the given polynomial, the least degree polynomials are,

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

[tex]f(x) = x^3-3x^2+\sqrt{5}x^2 +2x-\sqrt{5} x[/tex]

These polynomial having leading coefficient 1.

Now to check x = 0, 1, (2 [tex]-\sqrt{5}[/tex]) are zeros of which polynomial.

Consider, the first polynomial

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

plug x = 0

f(0) = 0 - 5(0) + 3(0) - 0

f(0) = 0

plug x = 1

f(1) = 1^3 - 5(1)^2 +3(1) - 1

f(1) = 1 - 5 + 3 - 1

f(1) = -2

f(1) ≠ 0

Therefore, 1 is not the zero of this polynomial.

Now consider, the next polynomial

[tex]f(x) = x^3-3x^2+\sqrt{5}x^2 +2x-\sqrt{5} x[/tex]

Plug x = 0

f(0) = 0

f(1) = 0

[tex]f(2-\sqrt{5} )=0[/tex]

Therefore, the polynomial [tex]f(x) = x^3-3x^2+\sqrt{5}x^2 +2x-\sqrt{5} x[/tex] having given zeros.

Answer:

[tex]f(x)=x^3-3x^2+\sqrt{5}x^2+2x-\sqrt{5}x[/tex]

Step-by-step explanation:

Given information:

Factor Theorem

If f(x) is a polynomial, and f(c) = 0, then (x – c)  is a factor of f(x).

Therefore, the function in factored form is:

[tex]\implies f(x)=1 \cdot x(x-1)(x-(2-\sqrt{5}))[/tex]

[tex]\implies f(x)=x(x-1)(x-2+\sqrt{5})[/tex]

Expand the factored function:

[tex]\implies f(x)=x(x^2-2x+\sqrt{5}x-x+2-\sqrt{5})[/tex]

[tex]\implies f(x)=x(x^2-3x+\sqrt{5}x+2-\sqrt{5})[/tex]

[tex]\implies f(x)=x^3-3x^2+\sqrt{5}x^2+2x-\sqrt{5}x[/tex]

Oleg is training for a triathlon. One day he jogged for 2 hours at x miles per hour . Then he bicycled for 2 hours at y miles per hour. Finally. He swam a distance. The total number of miles did not exceed 30. Express this as an inequality

Answer:

Step-by-step explanation:

You want to find the maximum or minimum value and where it occurs for the function F(x)=-3x²+18x+3.

The vertex form of a quadratic is ...

  f(x) = a(x -h)² +k . . . . . . . vertex at (h, k)

The graph opens downward if a < 0, and opens upward for a > 0. When the graph opens downward, the function has a maximum at the vertex. When the graph opens upward, the function has a minimum at the vertex.

We can put the function in vertex form as follows:

  F(x) = -3(x² -6x) +3 . . . . . factor out the leading coefficient

  F(x) = -3(x² -6x +9) +3 +3(9) . . . . . . subtract and add 3(9)

  F(x) = -3(x -3)² +30 . . . . . . . . . simplify to vertex form

Comparing this equation to the form shown above, we see ...

  a = -3 < 0 . . . . . . . . . the function has a maximum

  (h, k) = (3, 30) . . . . . the maximum is 30 at x=3

__

Additional comment

The square of the binomial in parentheses is ...

  (x -p)² = x² -2px +p²

That is, to "complete the square", we add the square of half the x-coefficient. Here, that coefficient is -2p=-6, so we want to add p²=9 inside parentheses. To keep the expression the same, we need to add the opposite amount outside parentheses. We are effectively adding 0 in the form of -3(9) +3(9) = 0 so the expression can be put in vertex form.

A graphing calculator can quickly show you the minimum or maximum of the function.

The probability for success is not the same for each trial, then the option D cannot be modelled using a geometric distribution.

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

One of the assumptions to consider before the use of a geometric distribution can be valid is that, the probability of success must be the same for each outcome.

In the option D, selection is done without replacement, meaning that, the number total possible outcome will decrease as we make each selection and will also depend on how the colours are being chosen.

Hence, the probability of success will differ for each outcome, thus the option D is correct.

The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.

Angles A and B are supplementary.

We have been given that m angle ∠B= 121.3°,

To determine the measure of angle A if the measure of angle B is 121.3°.

As per the property supplementary angles,

m∠A + m ∠B = 180°

m∠A + 121.3 ° = 180°

m ∠A = 180° - 121.3°
