The area of the conference table in Mr. Nathan’s office must be no more than 175 ft2. If the length of the table is 18 ft more than the width, x, which interval can be the possible widths?

Answers

Answer 1
The answer is  0 < x ≤ 7 

First, we know that width =  x
Which means that length = x +18

So, the possible equation for the Table's area is

X (X + 18)  ≤ 175

X^2 + 18x - 175  ≤ 0

Next, we need to calculate is by using complete square method
x^2 + 18x + 81 ≤ 175 + 81

(x + 9)^2 ≤ 256

|x + 9| ≤ sqrt(256)

|x + 9| ≤ +-16

-16 ≤ x + 9 ≤ 16

-16 - 9 ≤ x ≤ 16 - 9

-25 ≤ x ≤ 7

Since the width couldn't be negative, we can change -25 with 0,

so it become
 0 < x ≤ 7

Which is a graph of f(x)=4(1/2)x

Answers

We know that the basic equation of exponential equation equation is; 

y=ab^x 

Where a is the y-intercept/starting point and b is the value that x exponentially grows or decays. 

From the given equation, the two graphs with other intercepts (not 4) can be removed. 

Since b is between 0 and one, this function should be decaying. 

Next calculate the value of x when y=1. 

1=4(0.5)^x 
1/4=(1/2)^x 
log₀₋₅(1/4)=x 
2=x

Check which of the graphs have y=1, x=2. This would be the second graph, which would represent the equation y=4(0.5)^x 

Hope I helped :) 

In this exercise we have to be aware of the type of graph we have and identify its formula, like this:

As it is a graph of the equation of an exponential, we have that its form is given by:

Find dy/dx x^3+y^3=18xy

Answers

Final answer:

The student's question involves finding the derivative dy/dx for the equation [tex]x^3 + y^3 = 18xy[/tex]. This is done through implicit differentiation, resulting in dy/dx = [tex](18y - 3x^2) / (3y^2 - 18x).[/tex]

Explanation:

The student has presented an equation involving x and y and has asked for the derivative of y with respect to x (dy/dx). To find dy/dx, we use implicit differentiation because y is not isolated on one side of the equation. The given equation is [tex]x^3 + y^3 = 18xy.[/tex]

Start by differentiating both sides with respect to x:

The derivative of [tex]x^3[/tex] with respect to x is [tex]3x^2.[/tex]

The derivative of [tex]y^3[/tex] with respect to x is [tex]3y^2[/tex] times dy/dx (chain rule).

The derivative of 18xy with respect to x is 18y + 18x times dy/dx (product rule).

Bringing all terms involving dy/dx to one side gives:

[tex]3x^2 + 3y^2(dy/dx) = 18y + 18x(dy/dx)[/tex]

Solve for dy/dx:

[tex]3y^2(dy/dx) - 18x(dy/dx) = 18y - 3x^2[/tex]

Factor out dy/dx:

[tex]dy/dx (3y^2 - 18x) = 18y - 3x^2[/tex]

Finally, solve for dy/dx:

[tex]dy/dx = (18y - 3x^2) / (3y^2 - 18x)[/tex]

This expression represents the slope of the tangent to the curve at any point (x, y).

Jupiter's orbital radius is equal to 5 au. how luminous is jupiter compared to the sun

Answers

Jupiter is not as luminous as the sun. However, considering the fact that Jupiter is one of the largest gaseous planets in the solar system, and that it is relatively close to the earth compared to the Pluto, it is still visible in the night sky.

The luminosity of Jupiter compared to the Sun is [tex]\( 9.57 \times 10^{27} \)[/tex] Watts.

To find the luminosity of Jupiter compared to the Sun, we can use the inverse square law of brightness. The luminosity of a celestial body depends on its distance from the observer. Given that Jupiter's orbital radius r = 5 AU (Astronomical Units) and the Sun's luminosity is [tex]\( L_{\odot} = 3.828 \times 10^{26} \)[/tex] Watts, we can calculate the luminosity of Jupiter [tex](\( L_J \)).[/tex]

Find the distance ratio [tex](\( \frac{r_{\text{Jupiter}}}{r_{\text{Sun}}} \))[/tex]:

[tex]\[ \text{Jupiter's distance ratio} = \frac{5 \, \text{AU}}{1 \, \text{AU}} = 5 \][/tex]

Apply the inverse square law:

[tex]\[ \frac{L_{\text{Jupiter}}}{L_{\odot}} = \left( \frac{r_{\text{Sun}}}{r_{\text{Jupiter}}} \right)^2 \][/tex]

[tex]\[ L_{\text{Jupiter}} = L_{\odot} \times \left( \frac{r_{\text{Jupiter}}}{r_{\text{Sun}}} \right)^2 \][/tex]

[tex]\[ L_{\text{Jupiter}} = 3.828 \times 10^{26} \times (5)^2 \][/tex]

[tex]\[ L_{\text{Jupiter}} = 3.828 \times 10^{26} \times 25 \][/tex]

[tex]\[ L_{\text{Jupiter}} = 9.57 \times 10^{27} \, \text{Watts} \][/tex]

So, the luminosity of Jupiter compared to the Sun is [tex]\( 9.57 \times 10^{27} \)[/tex] Watts.

Here some steps are given to write the above function in vertex form.

Step 1: Factor a out of the first two terms

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

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

[tex]\text{Put a=x and b=3 in the identity, we get}[/tex]

[tex]x^2+2(x)(3)+3^2=(x+3)^2[/tex]

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

Hence, the f(x) can be written as

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

Therefore, the missing value in last step is 3

A dish tv satellite dish is the shape of a paraboloid. the dish is 36 inches wide, and 8 inches deep. how many inches should the receiver be located from the vertex for optimal reception? (round to the nearest thousandth)

Answers

The receiver is situated 10.125 inches from the vertex, is the correct response.

What is Parabola?

The line perpendicular to the directrix and passing through the focus (that is, the line that splits the parabola through the middle) is called the "axis of symmetry". The point where the parabola intersects its axis of symmetry is called the "vertex" and is the point where the parabola is most sharply curved. The distance between the vertex and the focus, measured along the axis of symmetry, is the "focal length". The "latus rectum" is the chord of the parabola that is parallel to the directrix and passes through the focus. Parabolas can open up, down, left, right, or in some other arbitrary direction. Any parabola can be repositioned and rescaled to fit exactly on any other parabola—that is, all parabolas are geometrically similar.

According to our question-

Make the origin of the parabola the vertex. Then, it has the equation y = bx^2.

The parabola crosses via (18,8), therefore 8 = b(182^) b = 0.02469 because

Its equation is y = 0.02469x2.

For best reception, the receiver should be positioned at the paraboloid's focus point.

The focus has a y-coordinate of

a = 1/(4b) = 1/0.098765

= 10.125 in

The receiver is situated 10.125 inches from the vertex, is the correct response.

Hence we can say that, the receiver is situated 10.125 inches from the vertex.

Final answer:

Using the formula [tex]f = \(\frac{d^2}{16h}\)[/tex] for a parabolic dish, where the dish is 36 inches wide (diameter) and 8 inches deep, the optimal location of the receiver is calculated to be approximately 10.125 inches from the vertex for best reception.

Explanation:

The question asks where the receiver should be placed on a satellite dish that has the shape of a paraboloid for optimal reception. The given dimensions are that the dish is 36 inches wide and 8 inches deep. A parabolic dish reflects signals to a focal point where the receiver is typically placed for optimal signal reception. We can use the properties of a parabolic shape to find the location of the focal point, also known as the focus of the parabola.

To find the focal length (distance from the vertex to the focus) of a paraboloid, we use the formula [tex]f = \(\frac{d^2}{16h}\)[/tex], where d is the diameter and h is the depth. Substituting our values in (d = 36 inches, h = 8 inches) we get the focal length [tex]f = \(\frac{36^2}{16 \times 8}\) = \(\frac{1296}{128}\) \approx 10.125[/tex] inches. Therefore, the receiver should be located approximately 10.125 inches from the vertex of the satellite dish for optimal reception.

The receiver's optimal location, rounded to the nearest thousandth, is therefore 10.125 inches from the vertex.
