Answer:

  1/x = (1+√5)/2 ≈ 1.618034

Step-by-step explanation:

Since you are only interested in the second part, we presume you have solved the quadratic equation to find ...

  x = (√5 -1)/2 ≈ 0.618034

The second part asks for 1/x. The usual method for rationalizing the denominator will be useful for this. Multiply numerator and denominator by the conjugate of the denominator.

  [tex]\dfrac{1}{x}=1\div\dfrac{\sqrt{5}-1}{2}=1\times\dfrac{2}{\sqrt{5}-1}\\\\=\dfrac{2(\sqrt{5}+1)}{(\sqrt{5}-1)(\sqrt{5}+1)}=\dfrac{2\sqrt{5}+2}{5-1}=\boxed{\dfrac{\sqrt{5}+1}{2}\approx1.618034}[/tex]

Additional comment

You may notice that 1/x = x+1.

Answer:

Evan's plant is 80 millimeters taller than Raj's plant

Step-by-step explanation:

If the plant will grow 1 centimeter every month, we can write an equation that relates the height of the plant with the number of months elapsed:

Let

H = height of the plant

M = number of months elapsed

H0 = initial height = 10cm

H (M) = (1)M + H0

H (M) = (1)M + 10

Where (1) is the constant rate of growth of 1 centimeter per month.

This is the equation of a line that intersects the H axis at H = 10.

Find the next 3 terms if it is a arithmetic sequence, 20.5, 12.4, 4.3, -3.8, -11.9

Answers

Answer: -20 -28.1 and -36.2

Step-by-step explanation:

20.5 - 12.4 = 8.1

12.4 - 4.3 = 8.1

4.3 - (-3.8) = 8.1

(-3.8) - (-11.9) = 8.1

(-11.9) - ([tex]n_{1}[/tex]) = 8.1

[tex]n_{1}[/tex] = -20

(-20) - ([tex]n_{2}[/tex]) = 8.1

[tex]n_{2}[/tex] = -28.1

(-28.1) - ([tex]n_{3}[/tex]) = 8.1

Rewrite the quadratic equation in standard form 4x^2=2x-6

Answers

Answer:

Answer Below....

Step-by-step explanation:

Answer:

4x^2 - 2x + 6

Step-by-step explanation:

The "standard form" of the quadratic equation is ax^2 + bx + c.

Here we have 4x^2 = 2x - 6, whose terms must be rearranged to resemble ax^2 + bx + c.  Term 4x^2 stays where it is, but + 2x - 6 on the right side must be moved to the left side, which results in:  4x^2 - 2x + 6

The ratio of men to women working for a company is 8 to 5. If there are 273 employees total, how many women work for the company?

Answers

Answer:

105 women

Step-by-step explanation:

8 to 5, sooo \/

8x + 5x = 273

13x = 273

x=273/13

x=21

8*21 = 168 men

5*21 = 105 women

(to check we can add 168 and 105 together and make sure we get 273. We do!)

-4x + 6x = 44

2x = 44

x = 44/2 = 22

x = 22

therefore value of x is 22 and 4x is 88

x = 22°

4x = 4(22) = 88°

Answers

Answer:

3√5

Step-by-step explanation:

Square root of 45

Square Root of 45: √45 = 6.708

We can find the square root of 45 using the following steps:

Step 1: Check whether the number is a perfect square or not. In this case, 45 is not a perfect square as it cannot be broken down into a product of two same numbers.

Step 2: Once the number is checked, the following process needs to be followed:

If the number is a perfect square, it can be written in this format √x2 = x

If it is not a perfect square, the square root is found using the long division method. It can also be written in its simplified radical form.

Since 45 is not a perfect square, we find its square root using the long division method. The simplified radical form of the square root of 45 is given below.

Simplified radical form of the square root of 45-

45 can be written as a product 9 and 5. Hence, square root of 45 can be expressed as, √45 = √(9 × 5) =  3√5. 45 is not a perfect square, hence, it remains within roots. The simplified radical form of the square root of 45 is 3√5.

8*9*11 = 792. cant be the box cuz 792 does not equal 729

Kendra has a painting canvas that is 29 inches wide by 33 inches high. She painted a red rose, which covered 30% of the canvas.
What was the area of the canvas which was covered by the red rose?

Answers

Answer:

287.1 inches of the canvas.

Step-by-step explanation:

To solve this, we need to first figure out the total area of the canvas. To do that, multiply width by height.

29*33=957

Now set up your equation for solving for the area of the canvas that the rose covers.

x/957=30/100

We did it where: x is the area of the rose covers, 957 is the amount of inches that the canvas takes up, and the right side of the equation is the percent.

Now cross multiply.

100x=28,710

Now divide both sides by 100.

x=287.1

The red rose covers 287.1 inches of the canvas.

Write an equation of the line (4,3) and (9,-2)

Answers

Answer:

y= -x + 7

Step-by-step explanation:

to get the equation of a line is y=mx+b

the slope, m, would be calculated (y1-y2)/(x1-x2)

thus we would substitute in (3--2)/(4-9)

which simplifies to 5/-5

or -1

now we know that m= -1

to solve for b we have to put the equation into point-slope form which is

y-y1= m(x-x1)

this would be y-3 = -(x-4)

y-3 = -x+4

y= -x+7

What is the domain and the range to this

Answers

Answer:

Look Down below :P

Step-by-step explanation:

If you were looking for if it even has a domain and range let's say if the point (15/4,7) should have read (15/4,17) then a plot of these points appears to show a hyperbola and the x and y (f(x)) axes look like Asymptotes. If the general function has the form f(x)=a/x, then there should be a consistent value for a which can be found be substituting the points in the equation. Take one point (17,15/4) and we get 15/4=a/17, from which a=255/4. f(x)=255     x/4. We have no negative values as examples so we cannot assume that the function is defined for negative values of x. f(x)=255 x/4 fits all the points except for (15/4,7), which is possibly mis-typed. The domain of the function is therefore all values of x>0 and the range of f(x) is f(x)>0, assuming continuity and extrapolation of the function.

If the point (15/4,7) is valid then f(x) as defined above is invalid or incomplete. f(x) may be a piece wise function where f(x)=7 if and only if x=15/4. For 0<x<15/4 and x>15/4, f(x)=255 x/4. These would be the domain for x. The range of f(x) is f(x)>0 and f(x)=7 only when x=15/4.

What is the image of the point (-5, -9) after a rotation of 90° counterclockwise
about the origin?

Answers

Answer:

(9, -5)

Step-by-step explanation:

If you rotate a figure 90 degrees counterclockwise, the coordinates will go from (x, y) to (-y, x).

So, let's start out with -y. The y-value of (-5, -9) is -9, and the negative value of that is -(-9) or 9. That goes first in our point: (9, x.) Now, we just keep our x-value the way it is, -5, and put that in our y-value: (9, -5). And there's our point after a 90 degree counterclockwise rotation.
