Answer: y = 17x + 114

Step-by-step explanation:

The equation for the slope-intercept form is y = mx + b.

Arrange the equation so that it resembles y = mx + b.

You will do this by multiplying and subtracting so y is on the left side of the equation and mx + b is on the right side of the equation.

y + 5 = 17(x + 7)

y + 5 = 17x + 119

y + 5 - 5 = 17x + 119 - 5

y = 17x + 114

Answer:

Y = 17x + 114

Step-by-step explanation:

1. Y + 5 = 17 (x+7)

2. Y + 5 = 17x + 119   [Multiply the numbers in parenthesis by 17.]

3. Y = 17x + 114.     [To keep the balance and move the 5 over, subtract it from 119.]

The chord joining the vertices of an ellipse is called the major axis, and its midpoint is the center of the ellipse.

The major axis of an ellipse is the chord that passes through the two vertices of the ellipse. It is the longest chord and its length is equal to twice the length of the semi-major axis of the ellipse. The midpoint of the major axis is the point that divides the major axis into two equal segments, and it coincides with the center of the ellipse. The center of the ellipse is the point of intersection of the major and minor axes, and it is equidistant from all points on the ellipse.

The measure of the major arc JLK will be 206°. Then the correct option is B.

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

The measure of the minor arc JK will be 154°.

Then the sum of the major arc and minor arc in a circle is 360°.

Then the major arc JLK will be given as,

JLK + JK = 360°

JLK + 154° = 360°

JLK = 206°

The measure of the major arc JLK will be 206°. Then the correct option is B.

Less than 1 is the eccentricity of an infinitely long ellipse.

The ratio of the focus's distance from the ellipse's centre and the ellipse's distance from one of its ends is called the eccentricity of an ellipse.

It is easy to understand how circular an ellipse is in relation to a circle when we assume its eccentricity. It also estimates the ovalness of the ellipse, and eccentricity close to 1 directs to the high degree of ovalness.

The eccentricity of an ellipse is always < 1, i.e. e < 1. The formula of the eccentricity of an ellipse is as follows:

Eccentricity = Distance from Focus/Distance from Directrix

Which can be written as

=> e = c/a.    

Where

e = Eccentricity of the ellipse

c = Distance of the focus from the centre of the ellipse

a = Distance of the endpoint of an ellipse from its centre

As we know, the eccentricity of an ellipse is always less than 1, So we can conclude that the eccentricity of an infinitely long ellipse is less than 1.

Therefore, less than 1 is the eccentricity of an infinitely long ellipse.

A polygon is called non-convex if there are "dents" or indentations in it, where the internal angle is greater than 180 degrees.

In other words, a non-convex polygon is a polygon whose line segments intersect, creating an interior angle greater than 180 degrees. This is in contrast to a convex polygon, where all of the interior angles are less than 180 degrees and none of the line segments intersect.

Non-convex polygons can have a variety of shapes and sizes, and can be composed of any number of sides. However, they are generally more difficult to work with mathematically than convex polygons, and often require more advanced techniques to analyze and understand their properties.

Step-by-step explanation:

A Venn diagram is a graphical representation of all possible logical relationships between a finite collection of sets. Venn diagrams are used to visualize how different sets overlap and the relationship between different groups of objects.

Venn diagrams are often used in statistics and probability to illustrate the relationship between different events.

In the context of probability, events A, B, and C are considered independent if the occurrence of one event does not affect the probability of the other events occurring. In other words, the probability of each event is independent of the other events.

To create a Venn diagram that illustrates three independent events A, B, and C, you would first draw three circles that are not overlapping.

Each circle represents one of the three events. Next, you would label each circle with the name of the corresponding event. In order to make the size of each circle proportional to the probability of the event occurring, you would adjust the size of each circle according to the probability of that event.

The larger the probability, the larger the circle. Finally, you would indicate the area of overlap between each pair of events. Because the events are independent, there should be no overlap between any of the circles. The Venn diagram would look something like this: In summary, to illustrate three independent events A, B, and C using a Venn diagram, you would draw three non-overlapping circles that represent each event and adjust their size to be proportional to the probability of that event.

There should be no overlap between any of the circles since the events are independent.

a) Mass of the Death Star: To find the mass of the death star, the given density function will be integrated over the entire volume of the star. Mass of the death star=∫∫∫ρ(r,θ,ϕ)dV =4π/15×r15 .

where dV=r2sinθdrdθdϕ As we have ρ(r,θ,ϕ)=r3ϕ2, so the integral will be

Mass of the death star=∫∫∫r3ϕ2r2sinθdrdθdϕ

Here, the limits for the variables are given by r = 0 to r

= r1;

θ = 0 to π; ϕ

= 0 to 2π.

So, Mass of the death star is given by:

Mass of the death star=∫02π∫0π∫0r1r3ϕ2r2sinθdrdθdϕ

=1/20×(4π/3)ρ(r,θ,ϕ)r5|02π0π

=4π/15×r15

b) Total energy of Obi Wan's home planet:

Total energy of Obi Wan's home planet can be obtained using the relation

E=∫4/3πρr3dVUsing the same limits as in part (a),

we haveρ(r,θ,ϕ)

=Mr33/3V

=∫02π∫0π∫0RR3ϕ2r2sinθdrdθdϕV

=4π/15R5 So,

E=∫4/3πρr3dV=∫4/3π(4π/15R5)r3(4π/3)r2sinθdrdθdϕE

=16π2/45∫0π∫02π∫0Rr5sinθdϕdθdr

On evaluating the integral we get,

E=16π2/45×2π×R6/6=32π3/135×R6

a) Mass of the death star=4π/15×r15, b) Total energy of Obi Wan's home planet=32π3/135×R6

i only have one, sorry!

Answer:

Step-by-step explanation:

Let the larger number = y

Let the smaller number = x

x/y = 9/11

y - x = 6

Add x to both sides of the second equation

y = 6 + x

Substitute into the first equation

x/(x + 6) = 9/11

Cross multiply

11x = 9(x + 6)

Remove the brackets

11x = 9x + 54

Subtract 9x from both sides.

2x = 54

x = 54/2

x = 27

y = 27 + 6

y = 33

(27,33)

The way I've done it, there isn't a second pair.

The isotopes of gallium-69 are Ga71 and Ga67.

Ga71 is an isotope of gallium-69 because it has the same number of protons (31) but a different number of neutrons (40) compared to the standard isotope of gallium-69 (31 protons and 38 neutrons).

Ga67 is another isotope of gallium-69 because it also has 31 protons but a different number of neutrons (36) compared to the standard isotope of gallium-69.

These isotopes have different mass numbers due to the varying number of neutrons, while still retaining the same number of protons. Isotopes of an element have the same atomic number (number of protons) but different mass numbers.

The best way to solve this problem is to imagine the situation as follows: Suppose that each position (first, second and third) is a numbered box. (first is box number one, and so on).

Now, imagine that each student is a ball that is numbered from 1 up to 11.

The situation translates to calculate in how many different ways we can put a ball in each box, without putting 2 balls in each box. We have the following

To solve this, we will use the multiplication principle. This principle relays on multiplying the number of possibilites for each box. Consider the case in which we will fill the box number 1. We can choose any of the numbers, so we have 11 posibilites. Now, suppose that we chose one number for box 1, and now we want to fill box 2. Then, we will have 10 possibilites only, since we already picked one. In the same manner, to fill the third box we have 9 possibilities. So the total number of possibilites is the product of this three numbers. That is

The (x, y) coordinates of point P are approximately (31.19, 20.67).

It is stated that the point P lies at a distance of r = 37 units from the origin and forms an angle of θ = 35° with respect to the x-axis, we can use trigonometry to find the x and y coordinates.

Using the trigonometric definitions, we have,

x = r * cos(θ) = 37 * cos(35°) ≈ 31.19

y = r * sin(θ) = 37 * sin(35°) ≈ 20.67

Therefore, the approximate (x, y) coordinates of point P are (31.19, 20.67). The coordinates (31.19, 20.67) represent the position of point P in the Cartesian coordinate system based on the given distance and angle measurements.
