The equation of the quadratic function is f(x) = x²+ 2/3x - 1/9

From the question, the given parameters are:

Roots = (-1 - √2)/3 and (-1 + √2)/3

The quadratic equation is then calculated as

f(x) = The products of (x - roots)

Substitute the known values in the above equation

So, we have the following equation

[tex]f(x) = (x - \frac{-1-\sqrt{2}}{3})(x - \frac{-1+\sqrt{2}}{3})[/tex]

This gives

[tex]f(x) = (x + \frac{1+\sqrt{2}}{3})(x + \frac{1-\sqrt{2}}{3})[/tex]

Evaluate the products

[tex]f(x) = (x^2 + \frac{1+\sqrt{2}}{3}x + \frac{1-\sqrt{2}}{3}x + (\frac{1-\sqrt{2}}{3})(\frac{1+\sqrt{2}}{3})[/tex]

Evaluate the like terms

[tex]f(x) = x^2 + \frac{2}{3}x - \frac{1}{9}[/tex]

So, we have

f(x) = x²+ 2/3x - 1/9

Answer:

Step-by-step explanation:
Slope is gradient which is, change in y
                                              change in x
so, on the graph, change in y = 10-2.5 = 7.5
                              change in x = 5-0 =5
so, gradient is, 7.5/5
                     = 3/2

Answer:

A) y = 23°

B) ∠A = 67°, ∠C = 113°, ∠D = 113°

Step-by-step explanation:

Hello!

Angle A and B are vertical angles, meaning they are equal in measure. We can solve for y by setting the two equations equal to each other.

Vertical angles are the opposite angles formed by the intersection of 2 lines.

Supplementary angles are angles that add up to 180°.

The value of y is 23°.

Measure of Angle A is 67°, as Angle A and B are vertical and equal in measure

Measure of Angle C is 113°, because the sum of angles on a line are equal to 180°, and are supplementary.

Measure of Angle D is also 113°, because it is vertical to Angle C.

Step-by-step explanation:

Factorize the polynomial using the given details.

Since one of the factors known, try to factor it out and futher:

Find its zero's:

Answer:

[tex]x=1, \quad x=\dfrac{3}{2}, \quad x=2[/tex]

Step-by-step explanation:

Factor Theorem

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

If the coefficients in a polynomial add up to 0, then (x - 1) is a factor.

Given polynomial function:

[tex]f(x)=2x^3-9x^2+13x-6[/tex]

Sum the coefficients:

[tex]\implies 2-9+13-6=0[/tex]

As the sum of the coefficients is zero, (x - 1) is a factor.

Therefore:

[tex]\implies f(x)=(x-1)(ax^2+bx+c)[/tex]

Expand the brackets:

[tex]\implies f(x)=ax^3+bx^2+cx-ax^2-bx-c[/tex]

[tex]\implies f(x)=ax^3+(b-a)x^2+(c-b)x-c[/tex]

Compare the coefficients with the given polynomial.

As the coefficient of the leading term of the polynomial is 2:

[tex]\implies a=2[/tex]

As the coefficient of the term in x² is -9:

[tex]\implies b-a=-9[/tex]

[tex]\implies b-2=-9[/tex]

[tex]\implies b=-7[/tex]

As the constant of the given polynomial is -6:

[tex]\implies c=6[/tex]

Substitute the found values of a, b and c into the factored form of the polynomial:

[tex]\implies f(x)=(x-1)(2x^2-7x+6)[/tex]

Factor the quadratic:

[tex]\implies 2x^2-7x+6[/tex]

[tex]\implies 2x^2-4x-3x+6[/tex]

[tex]\implies 2x(x-2)-3(x-2)[/tex]

[tex]\implies (2x-3)(x-2)[/tex]

Therefore, the fully factored polynomial is:

[tex]\implies f(x)=(x-1)(2x-3)(x-2)[/tex]

To find the zeros, set the function to zero:

[tex]\implies f(x)=0[/tex]

[tex]\implies (x-1)(2x-3)(x-2)=0[/tex]

Apply the zero-product property:

[tex]\implies x-1=0 \implies x=1[/tex]

[tex]\implies 2x-3=0 \implies x=\dfrac{3}{2}[/tex]

[tex]\implies x-2=0 \implies x=2[/tex]

Therefore, the real zeros of the given polynomial are 1, ³/₂ and 2.

The dimension are 75 * 50 i.e, Width = 50 cm , Length = 75 cm

Define Dimension

A measurable extent of a particular kind, such as length, breadth, depth, or height.

Let,

T = how taller the poster is

W = how wide the poster is

According to question given,

T = W + 25  ---eq(i)

The total height is calculated by multiplying the top border by 5 and the bottom border by 5. The entire height is then multiplied by the border's width, 5, times 2, so there are two tall sides. then multiplying by 5 times 2 widths.The equation looks like that,

5 * (2 (T + 10)) + 5 * (2 * W) = 1350

Now substitute the eq(i) value,

5 * (2 ((W + 25) + 10)) + 5 * (2 * W) = 1350

Now, solve for W,

5 * (2W +50 + 20) + 10W = 1350

10W + 5(70)+ 10W = 1350

20W + 350 = 1350

20W = 1350 - 350

20W = 1000

W = 1000/20

W = 50

Now, put the W value in eq(i)

T = 50 + 25

T = 75

The graph of g and f have equal intercepts while the slope of the graph of f is 5 times larger than the slope of the graph of g

Given: f(x) = 2x-5 and g(x)=2(0.2x)-5

To compare the two graphs, we can make use of the equation of a line:

The general form of the equation of a line is y = mx + c

Where m is the slope and c is the intercept

So we will compare two the functions with the equation of a line:

Comparing f(x) = (2x-5) with y = mx + c

The slope(m) of the line = 2 and the intercept(c) = -5

Also, comparing g(x) = 2(0.2x)-5 with y = mx + c

The slope(m) of the line = 2(0.2) = 0.4 and the intercept(c) = -5

Since the slope of f(x) = 2 and the slope of g(x) = 0.4. Thus:

slope of f(x) / slope of g(x)  = 2/0.4 = 5

So we can say the slope of  f(x) is  5 times the slope of g(x)

Therefore, the graph of g and f have the same intercept. But the slope of f(x) is  5 times the slope of g(x)

The equation of the line that is perpendicular to y = x + 6 is expressed as: y = -x - 7

The equation of a line can be written as y = mx + 1. The value of m is the slope while the value of b is the y-intercept.

The slopes of two lines that are perpendicular to each other are negative reciprocals. This means, if we multiply their slope values together, we will get -1.

Given the line, y = x + 6, the slope of the line is 1. The slope of the line it is perpendicular to is -1, because -1 is the negative reciprocal of 1.

Substitute m = -1 and (x, y) = (2, -9) onto y = mx + b to find the value of b:

-9 = -1(2) + b

-9 = -2 + b

-9 + 2 = b

-7 = b

b = -7

To write the equation of the perpendicular line, substitute m = -1 and b = -7 into y = mx + b:

Answer:

b) n > (-1/40)

Step-by-step explanation:

Given equation,

→ n - (3/8) > (-2/5)

Now the value of n will be,

→ n - (3/8) > (-2/5)

→ n > (-2/5) + (3/8)

Hence, value of n is -1/40.

Quinn got paid $121,560 in his first career and on switching, he made 55% less, i.e. he made 45% of his previous career.

This is because, if in a previous career he made 100%, then a 55% reduction in salary annually would mean, he is left with only 45%.

Let us suppose, previous salary as x

then, x= $121,560

so, 45% of x= 45% of $121,560

i.e. 45% of x= 45/100 x 121560

therefore, 45% of x= $54,702

Quinn makes $54,702 now.

Therefore, a reduction in 55% of earlier salary would mean that Quinn's salary reduced from $121,560 to $54,702
