Which shape is the most general of the quadrilaterals below?

Answer:

X = 3

Step-by-step explanation:

To solve this you want to first make the X variable alone by itself by moving it to the left or right it doesn't really matter, for this I moved it to the left making the new equation

-x = -1 - 2

I then make the 2 a negative using the order of operations and a negative adding a negative makes -3 making the following

-x = -3

then I change the signs making it

x = 3

Answer: slope

Step-by-step explanation:

In the linear function, f(x) =3x +10 the 3 represents the slope of the line

To solve the present problem we can just use a formula use the following strategy:

For the first choice, there are 7 possibilities (all the 7). For the second choice, there are 6 possibilities (all the 7 less the first already chosen). For the third choice 5, then 4, and 3. From this, we know that the number of possible arranges is the multiplication of these numbers.

Because the order is something thar is important, we concluded that the correct answer is: A. 2,520

The ratios of y over x are all equal to 1/3, thus we may infer that: B. the table is proportionate.

What is a Proportional Relationship?

Any pair of values in a table that depicts a proportionate relationship have the same value for the proportionality constant, k, where k = y/x.

Check each pair of values in the table to see if k is the same:

(36.75, 12.25):

k = 12.25/36.75 = 0.33

(16.8, 5.6):

k = 5.6/16.8 = 0.33

(77.1, 25.7):

k = 25.7/77.1 = 0.33

It is proportionate because the ratios of y across x are all equal to 1/3, which implies that the value of k is identical for all values.

The value of r = -9 is a solution, and r = -11 is not a solution.

We are given a quadratic equation.

r² + 11r + 28 = 10

We need to verify whether r = -9 and r = -11 are the solutions of the above quadratic equation or not.

We will first simplify the quadratic equation.

r² + 11r + 28 = 10

r² + 11r + 28 - 10 = 0

r² + 11r + 18 = 0

Now, we will draw the graph of the equation :

y = r² + 11r + 18

Now, we will see the roots of the equation.

We will see the x-coordinates of the intersection points of the graph and the x-axis.

The graph is attached below.

We can see that the roots of the equation are r = -9 and r = -2.

So, r = -9 is a solution, and r = -11 is not a solution.

The change in wavelength of the radio signal is 100m.

The change in wavelength of the radio can be calculated using the velocity of the given radio signal.

Let's substitute the values and solve.

But then, we have to convert the velocity from km to m

[tex]1km = 1000m\\3000km = x\\x = 3000000m[/tex]

we solve the wavelength here by

[tex]c = \lambda v\\3.0*10^8 = \lambda * 3.0^6\\\lambda = \frac{3.0*10^8}{3.0*10^6} \\\lambda = 1.0*10^2m\\\lambda = 100m[/tex]

QUESTION

Eight men can do a piece of work in 12

days. How long will 6 men take to do the

same work if they work at the same rate?

SOLUTION

Let X be thr time taken for 6 men to work at the same rate

Looking at the question, it is an indirect proportion

because as the number of men increases, the time taken to do the work decreases

So therefore;

8 men = 6 men

X days = 12 days

cross-multiply

6 x X = 12 x 8

6X = 96

divide both-sidde of the equation by 6

6X/6 = 96/6

X = 16 days

Therefore, it takes 16 days for 6 men men to do the work at the same rate.

Take into account that only reflection over lines which cross the center of the polygon and the midpoints of opposite sides, will map the polygon onto itself (the same for lines which cross opposite vertex of the figure).

Then, from the given answer choices, the following ones are true:

- A reflecion across line b, trough one vertex, the center d.

- A reflection across line c, trough the midpoints of opposite sides.

Now, related to the rotation, if θ (the angle of rotation) is such an angle that 360/θ is an integer, and the number of sides of the figure is multiple of the integer, then, the polygon will map onto itself after the transformation.

For θ = 60 degrees, 360/60 = 6

For θ = 120 degress, 360/120 = 3

Then, the following is true:

- A rotation of 60 degrees around the center point d.

- A rotation of 120 degrees around the center point d.

Step-by-step explanation:

The domain is [1,∞) and the range is [0,∞).

The relation given on the graph is a function for which the domain and the range are asked to be identified.

Examining the graph, the function has values corresponding the x-values from 1 (including 1). That is, at x = 1, the function value is 0. From there, the function continues without any break and extends to infinity. So the function is continuous.

Hence the domain and range can be best described in interval notation.

The domain of a function is the set of x-values for which the function has values or the function is defined.

As the function has values from x = 1 and extends to infinity, the domain is [1,∞).

The range of a function is the images of the function corresponding to the domain values.

Considering the y-values corresponding to the domain, which are the function values, the range is [0,∞).

The function that we want to get is:

t(h) = √(-h + 500)/4

And the height is 250 ft after 3.95 seconds.

Here we have the height function defined as:

h(t) = 500 - 16t²

And we want to write t as a function of h, so we just need to isolate the variable t.

h - 500 = -16*t²

(-h + 500)/16 = t²

√((-h + 500)/16) = t

√(-h + 500)/4 = t

This is the function that defines h as a function of t. Notice that we only care for the positive solution of the square root.

The time at which the height is 250ft is given by:

√(-250 + 500)/4 = t

√(250)/4 = 3.95

So the height after 3.95 seconds is 250ft.

let's take a quick look at the (a , bi) pair, "a" is positive whilst "b" is negative, that means the IV Quadrant, now let's keep in mind that tan⁻¹(x) has a range that lies on the I and IV Quadrants, so, if you check in your calculator for tan⁻¹(x) for those values, you'll notice it gives the one in the I Quadrant, namely 40.38°, however our coordinate pair is on the IV Quadrant, so we need its twin.

Make sure your calculator is in Degree mode.

The equation contains two unknown variables. They are usually x and y. The ordered pair would be written as (x, y). To determine if the ordered pair is a solution of the equation, we would substitute the value of x into the equation.

(-5,-5) a solution to the system 1 which is x + y = -10.

An approach of pinpointing a point's location on the planet is to use a coordinate system. To pinpoint a point's location, most coordinate systems use two numbers, called a coordinate. Each of these numbers represents the distance between the point and the origin, a fixed point of reference. How far left or right the point is in relation to the origin is indicated by the first integer, also referred to as the X value. How much above or below the origin the point is can be determined by the second integer, called the Y value. The origin is located at the coordinates 0, 0.

Because they indicate locations on a sphere or globe, longitude and latitude belong to a specific category of coordinate systems called spherical coordinate systems.

The reason is that if we put the values of x and y in the given equation it results up to be the same for the first one .
