Write the cubic polynomial function f(x)in expanded form with zeros −6, −4,and −1,given that f(−2)=−32.

Answers

Answer:

[tex]f(x)=4x^3+44x^2+136x+96[/tex]

Step-by-step explanation:

Polynomials

It's possible to build a polynomial function by knowing its zeros and leading coefficient.

Given the zeros of a third-degree polynomial: x=x1, x=x2, and x=x3, the function is:

[tex]f(x)=a(x-x_1)(x-x_2)(x-x_3)[/tex]

Where a is the leading coefficient.

We are given the zeros -6, -4, and -1, thus:

[tex]f(x)=a(x+6)(x+4)(x+1)[/tex]

The value of a can be calculated by substituting the point (-2,-32):

[tex]a(-2+6)(-2+4)(-2+1)=-32[/tex]

Calculating:

[tex]a(4)(2)(-1)=-32[/tex]

[tex]-8a=-32[/tex]

Dividing by -8:

[tex]a = -32/(-8) =4[/tex]

a = 4.

The polynomial is now complete:

[tex]f(x)=4(x+6)(x+4)(x+1)[/tex]

Operating:

[tex]f(x)=4(x^2+10x+24)(x+1)[/tex]

[tex]f(x)=4(x^3+11x^2+34x+24)[/tex]

[tex]\mathbf{f(x)=4x^3+44x^2+136x+96}[/tex]

Work out the percentage change to 2 decimal places when a price of £12 is increased to £15.99. Work out the percentage change to 2 decimal places when a price of £12 is increased to £15.99.

Answers

Answer:

[tex]\%Increase = 33.25\%[/tex]

Step-by-step explanation:

Given

Initial = 12

Final = 15.99

Required

Determine the percentage increment

This is calculated as thus:

[tex]\%Increase = \frac{Final - Initial}{Initial} * 100\%[/tex]

Substitute values for Initial and Final

[tex]\%Increase = \frac{15.99 - 12}{12} * 100\%[/tex]

[tex]\%Increase = \frac{3.99}{12} * 100\%[/tex]

[tex]\%Increase = \frac{3.99* 100\%}{12}[/tex]

[tex]\%Increase = \frac{399\%}{12}[/tex]

[tex]\%Increase = 33.25\%[/tex]

Hence, the percentage increment is 33.25%

A line passes through the point (10,9) and has a slope of 3/2. Write an equation in slope intercept form for this line

Answers

Answer:

The equation of line passing through (10,9) and having slope 3/2 is: [tex]y = \frac{3}{2}x-6[/tex]

Step-by-step explanation:

The slope intercept form of a line is given by:

[tex]y=mx+b[/tex]

We are given

Slope = m = 3/2

Point = (10,9)

Putting the value of the slope in the equation we get

[tex]y = \frac{3}{2}x+b[/tex]

b is the y-intercept. To find the y-intercept we have to put the point through which the line passes in the equation.

Putting (10,9) in the equation

[tex]9 = \frac{3}{2}(10) +b\\9 = 15+b\\b = 9-15\\b = -6[/tex]

Putting b=-6 in the equation

[tex]y = \frac{3}{2}x-6[/tex]

Hence,

The equation of line passing through (10,9) and having slope 3/2 is: [tex]y = \frac{3}{2}x-6[/tex]

Find the equation of the circle that has a diameter with endpoints (-4,8) and (4,-4)

Answers

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

First we need to find the distance between two points which is the diameter of the circle .

_________________________________

Suppose :

a = ( - 4 , 8 )

b = ( 4 , - 4 )

We have following equation to find the distance between two points.

[tex]distance = diameter = d[/tex]

[tex]d = \sqrt{ ( \: {y(b) - y(a)} \: )^{2} + ( \: {x(b) - x(a)} \: )^{2} } \\ [/tex]

Now just need to put the coordinates :

[tex]d = \sqrt{ ({ - 4 - 8})^{2} + ( \: {4 - ( - 4)} \: )^{2} } \\ [/tex]

[tex]d = \sqrt{ ({ - 12})^{2} + ({4 + 4})^{2} } [/tex]

[tex]d = \sqrt{ ({ - 12})^{2} + ({8})^{2} } [/tex]

[tex]d = \sqrt{144 + 64} [/tex]

[tex]d = \sqrt{208} [/tex]

[tex]d = \sqrt{4 \times 52} [/tex]

[tex]d = \sqrt{4 \times 4 \times 13} [/tex]

[tex]d = \sqrt{ {4}^{2} \times 13 } [/tex]

[tex]d = 4 \sqrt{13} [/tex]

This is the diameter of the circle.

We know that :

[tex]diameter = 2 \times radius[/tex]

So :

[tex]4 \sqrt{13} = 2 \times radius[/tex]

Divide sides by 2

[tex] \frac{4 \sqrt{13} }{2} = \frac{2 \times radius}{2} \\ [/tex]

[tex]2 \sqrt{13} = radius[/tex]

Remember it.

_________________________________

To find the equation of the circle except the radius , we need the coordinates of the centre.

The midpoint of the diameter is the centre of the circle .

So we have to find the midpoint of the diameter .

Look :

[tex]midpoint = center = o[/tex]

[tex]o = ( \: \frac{x(a) + x(b)}{2} \: , \: \frac{y(a) + y(b)}{2} \: ) \\ [/tex]

[tex]o = ( \: \frac{ - 4 + 4}{2} \: , \: \frac{8 - 4}{2} ) \\ [/tex]

[tex]o = ( \: \frac{0}{2} \: , \: \frac{4}{2} \: ) \\ [/tex]

[tex]o = ( \: 0 \: , \: 2 \: )[/tex]

This the coordinates of the centre.

_________________________________

Equation of the circle has a form like this :

[tex]( {x - m})^{2} + ({y - n})^{2} = {r}^{2} [/tex]

In which :

[tex]m = x - coordinate \: \: of \: \: the \: \: center \\ [/tex]

[tex]n = y - coordinate \: \: of \: \: the \: \: center \\ [/tex]

[tex]r = radius[/tex]

_________________________________

[tex]o = ( \: 0 \: , \: 2 \: )[/tex]

[tex]radius = 2 \sqrt{13} [/tex]

Thus :

[tex] ({x - 0})^{2} + ({y - 2})^{2} = ({2 \sqrt{13} })^{2} \\ [/tex]

[tex] {x}^{2} + ({y - 2})^{2} = 4 \times 13[/tex]

[tex] {x}^{2} + ({y - 2})^{2} = 52 [/tex]

This is the equation of the circle .

And we're done....

"X is the number of red marbles that Tonya has in her hand after she selects four marbles from a bag containing four red marbles and two green ones and then notes how many there are of each color."

Answers

Answer:

Explained below.

Step-by-step explanation:

There are four red marbles (R) and two green marbles (G) in the bag.

The random variable X is defined as the number of red marbles that Tonya has in her hand after she selects four marbles from the bag.

The probability of selecting a red marble is:

[tex]P(X)=\frac{4}{6}=0.667[/tex]

The sample space of X can be defined as follows:

Outcomes: {(RGGG), (RRGG), (RRRG), (RRRR), (RRGR), (RGRR), (GRRR), (RGRG), (GRRG), (RGGR), (GRGR), (GRGG), (GGRG), (GGGR), (GGGG)}

Answers

Answer:

Here is how to find the equation of the line using point-slope form

Formula for the equation of a line in point-slope form: y - y₁ = m(x - x₁)

Now that we have the formula, we plug in what we are given.

y - 9 = 4(x + 3)

We can covert this into slope-intercept form by solving for y.

[tex]y - 9 = 4(x + 3)\\\\y - 9 = 4x + 12\\\\y = 4x + 21[/tex]

Our equation for this line is: y = 4x + 21.

We can prove this by graphing the line, like so:

Answers

Answer:

$ 14.25 this is probably the answer

The required two expressions are

(1-0.05)P

0.95 P

Step-by-step explanation:

First method : Here, the original price of pillow = P,

She marks them down 5%

Thus, the selling price = P - 5% of P = P - 0.05 P = (1-0.05)P

Second method :

Since, some number is 100% of itself,

⇒ 100 % = P

⇒ 1 % = P/100 = 0.01 P

Also, by decreasing 5 % from 100 %

The remaining percentage = 100 - 5 = 95%

⇒ 95 % = 95 × 0.01 = 0.95 P

Stephanie also is 2/5 m Ike’s in 1/4 hour. What is her speed in mikes per hour?

Answers

Answer:

1.6 m/hr

Step-by-step explanation:

(Time) 1/4 of an hour = .25 or 15 mins

Distance = 2/5 mile or .40

Speed = distance / time

Speed = .40 / .25

Speed = 1.6 m/hr

Answer:

1 3/5 or 1.6 mph

Step-by-step explanation:

2/5 of a mile = 0.4 miles

0.4 x 4 = 1.6 or 1 3/5 (you get the 4 from multiplying 1/4 of an hour by 4 to get one hour)

Answers

Answer: The correct option is option (B) 1.08(0.87y).

Step-by-step explanation:

The answer is B

A beach is 2 3/5 miles long. Pets are allowed on 1/3 of the beach. How many miles of beach are pets allowed?

Answers

They are allowed in .87 miles of the beach 2.6*.3333= .87 miles

Answer:

13/15 of 1 mile, or 0.86666 miles

Step-by-step explanation:

If you are working with fractions, you can take the 2 3/5 miles of beach and convert that to 13/5 (10/5 = 2, then add the 3/5 = 10/5+3/5 = 13/5). Once converted, you can find out how much of that number allows pets by dividing that number by 3, or multiplying the result by 1/3.

13/5 * 1/3 = 13/15.

Another way to do this is to convert the original miles (2 3/5) to a decimal, which gives you 2.6 miles. Then take the 2.6 miles and again, either divide by 3 or multiply by 1/3 (which is basically the same thing). 2.6 ÷ 3 = 0.86666

Hope this helps!
