What’s the slope of the line

Answers

Answer:

The slope is -3

Step-by-step explanation:

Select two points on the line.  I have selected the points (1,5) and (2,2).  The slope is the change in y over the change in x.  The y values are 2 and 5,  The x values are 2 and 1.  You find the change by subtracting.

[tex]\frac{2-5}{2-1}[/tex] = [tex]\frac{-3}{1}[/tex] = -3

Another way to look at this is seeing the slope as the rise over the run.  If you start at (1,5) and only move right or left and up and down to get to (2,2), you would have to move straight down 3 spaces and then 1 space right.  Down is negative and right is positive, so the slope would be [tex]\frac{-3}{1}[/tex] which equals -3.

Has an album that holds. 500 Each page of the album holds 5 photo. If 59​% of the album is​ empty, how many pages are filled with photos​?

Answers

The number of pages with photos rounded to the nearest whole number is 204 pages.

First, we need to find out how many pages of the album are empty. Since 59% of the album is empty, that means 41% of the album is filled with photos.

To find out how many photos are in the album, we multiply the number of pages by the number of photos per page:

500 pages x 5 photos per page = 2500 photos

To find out how many pages are filled with photos, we need to take 41% of the total number of pages:

500 pages x 0.41 = 205 pages

However, since we're looking for the number of pages with photos rounded to the nearest whole number, we round down to 204 pages. Therefore, each of the 18 students would receive 204/18 = 11.33 pages of photos (rounded to the nearest hundredth).

Answers

The answer is (a) [tex]$-\frac{9}{2}$[/tex].

How to find the area of the bounded region?

To find the area of the bounded region determined by the curves [tex]$x^2=8y[/tex]and x + 4y - 4 = 0, we first need to find the intersection points of the two curves.

From the equation [tex]$x^2=8y$[/tex], we get [tex]$y=\frac{x^2}{8}$[/tex] Substituting this in the equation x + 4y - 4 = 0, we get [tex]$x+4\left(\frac{x^2}{8}\right)-4=0$[/tex], which simplifies to [tex]$x^2+8x-32=0$[/tex]. Solving for x, we get [tex]$x=-4\pm 4\sqrt{3}$[/tex].

Since the parabola [tex]$x^2=8y$[/tex] opens upwards, the area of the bounded region can be calculated as follows:

[tex]Area }=\int_{-4-4 \sqrt{3}}^{4 \sqrt{2}} \int_{\frac{x^2}{8}}^{(4-x) / 4} d y d x[/tex]

Integrating with respect to y first, we get:

[tex]\text { Area }=\int_{-4-4 \sqrt{3}}^{4 \sqrt{2}}\left(\frac{4-x}{4}-\frac{x^2}{8}\right) d x[/tex]

Simplifying and evaluating the integral, we get:

Given: ABCD is a rhombus and △ACB ≅ △DBC

Prove: ABCD is a square

Answers

Given: ABCD is a rhombus and △ACB ≅ △DBC

Prove: ABCD is a square

Proof:

1. ABCD is a rhombus, so AB = BC = CD = DA.
2. △ACB ≅ △DBC, so AC = DB and ∠ACB = ∠DBC.
3. Since ABCD is a rhombus, opposite angles are congruent, so ∠ABC = ∠CDA and ∠BCD = ∠DAB.
4. Since ∠ACB = ∠DBC, then ∠ACB + ∠ABC + ∠BCD = ∠DBC + ∠DAB + ∠CDA.
5. Substituting the congruent angles from step 3, we get ∠ABC + ∠CDA + ∠BCD + ∠DAB = 360°.
6. Since the sum of the angles of a quadrilateral is 360°, then ABCD is a quadrilateral.
7. Since all sides and angles of ABCD are congruent, then ABCD is a square.
A B C D is a rhombus so if you turn it sideways you get a square

Sketch the vector field F(r) = -r / ||r||^3 in the xy-plane. Select all that apply. The lengths of the vectors decrease as you move away from the origin. All the vectors point towards the origin. The length of each vector is 1. All the vectors point in the same direction. All the vectors point away from the origin.

Answers

To sketch the vector field F(r) = -r / ||r||^3 in the xy-plane, we can first observe that this is a radial vector field that points towards the origin. As ||r||^3 is the cube of the distance from the origin, the denominator increases much faster than the numerator, causing the lengths of the vectors to decrease as we move away from the origin. Therefore, the first statement "The lengths of the vectors decrease as you move away from the origin. All the vectors point towards the origin" is true.

As for the second statement, "The length of each vector is 1. All the vectors point in the same direction. All the vectors point away from the origin", it is not true for this vector field. The length of each vector depends on the distance from the origin and is not constant. Also, the vectors point towards the origin and not away from it. Therefore, this statement is false.

In summary, the correct answer is: The lengths of the vectors decrease as you move away from the origin. All the vectors point towards the origin.

To sketch the vector field F(r) = -r / ||r||^3 in the xy-plane and determine which statements apply, follow these steps:

1. Recognize that F(r) is a radial vector field with its direction determined by the term -r, which points towards the origin, and its magnitude determined by 1/||r||^3.

2. Notice that as you move away from the origin (increasing the value of ||r||), the magnitude of the vector field decreases because the denominator ||r||^3 increases, making the overall value of the vector field smaller.

3. Observe that all vectors point towards the origin because of the negative sign in the term -r.

4. Since the magnitude of the vector field is determined by 1/||r||^3 and not a constant value, the length of each vector is not 1.

5. As the vector field is radial and determined by the term -r, the vectors do not point in the same direction and do not point away from the origin.

From this analysis, we can conclude that the following statements apply:

- The lengths of the vectors decrease as you move away from the origin.
- All the vectors point towards the origin.

Answers

The value of  f(-1) = 1 - (-1)²/₃ = 2/3 and f(1) = 1 - 1²/₃ = 2/3.

To find values c in (-1,1) such that f'(c) = 0, we take the derivative of f(x): f'(x) = -2x/3. Setting f'(c) = 0, we get -2c/3 = 0, which implies that c = 0. Therefore, the only value of c in (-1,1) such that f'(c) = 0 is c = 0.

Rolle's Theorem states that if a function is continuous on a closed interval [a,b], differentiable on the open interval (a,b), and f(a) = f(b), then there exists at least one point c in (a,b) such that f'(c) = 0.

In this case, f(x) satisfies the conditions of Rolle's Theorem on the interval [-1,1]. We have shown that there exists exactly one point c in (-1,1) such that f'(c) = 0, namely c = 0. Therefore, Rolle's Theorem holds true for f(x) on the interval [-1,1].

Your answer: b. diverges

To apply the Integral Test, we first need to confirm that the function f(x) = 1/(2x + 8) is continuous, positive, and decreasing on the interval [1, ∞). Since the function meets these conditions, we can apply the Integral Test.

Now, let's evaluate the integral:

To solve this, we can use the substitution method:

let u = 2x + 8, so du = 2 dx. Now, when x = 1, u = 10, and when x → ∞, u → ∞.
Now, the integral becomes:
(1/2) ∫[10,∞] (1/u) du

This is an improper integral, and its form is a p-series where p = 1. We know that a p-series converges if p > 1 and diverges if p ≤ 1. In this case, p = 1, so the integral diverges.

The final equation of the circle is: (x - 4)²+(y - 3)² =8.

What us equation of circle?

The set of all points in a plane that are equally spaced from a fixed point known as the centre is described by the equation of a circle.

It is usually written in the form (x-h)² + (y-k)² = r², where (h, k) represents the center and r represents the radius of the circle.

To find the equation of the circle, we need to find the center of the circle and its radius using the given endpoints of the diameter.

The circle's centre corresponds to the diameter PQ's midpoint.Taking the average of the x-coordinates and the average of the y-coordinates will yield the midpoint's coordinates:

x-coordinate of midpoint = (6 + 2)/2 = 4

y-coordinate of midpoint = (5 + 1)/2 = 3

(4, 3) is the center of circle.

The radius of circle is half the distance between the endpoints of      diameter:

r = 1/2 × √((6 - 2)² + (5 - 1)²) = 1/2 × √(16 + 16) = 1/2 × √(2) = 2√(2)

Therefore, the equation of the circle with center (4, 3) and radius 2√(2) is:

Use the form |x-b| c to write an absolute value inequality that has the solution set 5

Answers

One possible absolute value inequality with the solution set 5 is:

| x - 5 | ≤ 0

What is the absolute value inequality?

An absolute value inequality is a type of inequality that involves the absolute value of a variable. The absolute value of a number is its distance from zero, and it is always a non-negative value.

The general form of an absolute value inequality is:

| f(x) | < a

where f(x) is an algebraic expression involving x, and a is a positive number.

According to the given information

An absolute value inequality with the solution set of 5 can be written in the form:

| x - b | ≤ c

where b is the value around which x can vary and c is the maximum distance from b to the boundary of the solution set.

To obtain a solution set of 5, we need to choose b as the midpoint between the two endpoints of the solution set, which is (5 + 5)/2 = 5.

The distance from b to either endpoint of the solution set is 5 - 5 = 0. Therefore, we can choose c to be any value greater than or equal to 0.

Answers

The volume of the given solid is 12 cubic units.



To evaluate the given double integral, we can first identify it as the volume of a solid. In this case, the integrand is (16-8y), which represents the height of the solid at any given point (x,y) in the region R=[0,1]x[0,1].

Thus, to find the volume of this solid, we need to integrate this height function over the entire region R.

∫ ∫ R (16 − 8y)dA = ∫₀¹ ∫₀¹ (16-8y) dx dy

Evaluating this double integral using iterated integration, we get:

∫₀¹ ∫₀¹ (16-8y) dx dy = ∫₀¹ [16x - 8yx] from x=0 to x=1 dy

= ∫₀¹ (16-8y) dy

= [16y - 4y²] from y=0 to y=1

In a study of helicopter usage and patient? survival, among the 55,673 patients transported by? helicopter, 250 of them left the treatment center against medical? advice, and the other 55,423 did not leave against medical advice. If 60 of the subjects transported by helicopter are randomly selected without? replacement, what is the probability that none of them left the treatment center against medical? advice?

Answers

To calculate the probability that none of the 60 randomly selected subjects left the treatment center against medical advice, we will use some steps.

Those steps are:
1. Calculate the probability of a single subject not leaving against medical advice.
2. Calculate the probability of all 60 subjects not leaving against medical advice.

Step 1:
There are a total of 55,673 patients, out of which 55,423 did not leave against medical advice. So, the probability of a single subject not leaving against medical advice is:
P(not leaving) = (number of patients not leaving) / (total number of patients)
P(not leaving) = 55,423 / 55,673 ≈ 0.9955

Step 2:
Since the subjects are randomly selected without replacement, we need to adjust the probability for each subsequent selection. However, as the sample size (60) is much smaller than the total number of patients (55,673), the difference in probabilities will be negligible. Therefore, we can assume that the probability for each subject remains approximately the same.

To calculate the probability that none of the 60 subjects left the treatment center against medical advice, we will multiply the probability of each subject not leaving against medical advice:

P(all 60 not leaving) = (P(not leaving))^60
P(all 60 not leaving) = (0.9955)^60 ≈ 0.7409

So, the probability that none of the 60 randomly selected subjects left the treatment center against medical advice is approximately 0.7409 or 74.09%.

prove that the function f : r − {2} → r − {5} defined by f (x) = 5x 1 x − 2 is bijective

Answers

The correct answer for the function  is both injective and surjective and it's proves that the function is bijective.

Given:

[tex]f(x) = \dfrac{5x+1}{x-2}[/tex]

If the function is both injective and surjective, the function is bijective:

Check Injective:

For every value in input in the function, their always exist a different output.

for [tex]x =1[/tex]

[tex]f(x)= \dfrac{5(1)+1}{1-2} \\\\= -6[/tex]

for [tex]x=3[/tex]

 [tex]f(x)= \dfrac{5(3)+1}{3-2} \\\\= 16[/tex]

As value for different output is different, function is Injective;

To check Surjectivity:

Show that for every y ∈ R −{5}, there exists an x ∈ R −{2} such that f (x) = y.

Let y ∈ R − {5}.  find an x ∈ R − {2} such that f (x) = y.

Solve f (x) = y for x.

[tex]\dfrac{5x + 1}{x-2} = y[/tex]

[tex]5x+1=xy- 2y[/tex]

[tex]xy-5x-2y+1=0[/tex]

[tex]x(y-5)-2y+1=0[/tex]

[tex]x=\dfrac{2y-1}{ y-5}[/tex]

[tex]f(x) = y[/tex]

The function is bijective.

Answers

The first part of the question asks us to complete the table and find the slope of the graph at the given point for two different functions. For the function (3x)^4, the derivative is 12(3x)^3. For the function r(θ) = 4 sin θ at the point (0,0), the slope of the graph is 4.

Let's complete the table and find the slope of the graph at the given point using the terms "derivative" and "slope."

1. Original Function: (3x)^4

Rewrite: (3x)^4
Differentiate: Using the power rule, d/dx[(3x)^4] = 4 * (3x)^(4-1) * d/dx(3x)
Simplify: 4 * (3x)^3 * 3 = 12(3x)^3

2. Function: r(θ) = 4 sin θ, Point: (0, 0)

To find the slope of the graph at the given point, we'll differentiate the function r(θ) with respect to θ.

Differentiate: dr/dθ = d/dθ [4 sin θ] = 4 * d/dθ [sin θ] = 4 * cos θ

Now, let's find the slope at the point (0, 0) by plugging θ = 0 into the derivative:

Slope: 4 * cos(0) = 4 * 1 = 4

So, the slope of the graph at the point (0, 0) is 4. To confirm your results, you can use the derivative feature of a graphing utility.

find x such that the matrix is equal to its own inverse. a = 5 x −6 −5

Answers

For the value of x = 4/5 (= 0.8) the matrix a = [tex]\left[\begin{array}{cc}5&x\\-6&-5\end{array}\right][/tex] is equal to its own inverse.

The matrix a is given as,

a = [tex]\left[\begin{array}{cc}5&x\\-6&-5\end{array}\right][/tex]

The value of x is such that a is equal to its inverse, that is,

a = [tex]a^{-1}[/tex] ___(1)

Inverse of an matrix, say a, can be calculated using the formula ,

[tex]a^{-1}\\[/tex] = (adjoint of matrix a) / (determinant of matrix a)

Therefore, Adjoint of matrix a = [tex]\left[\begin{array}{cc}-5&-x\\6&5\end{array}\right][/tex]

where,

As element of the adjoint matrix in row 1 and column 1 is cofactor of the matrix a in row 1 and column 1,  

As element of the adjoint matrix in row 1 and column 2 is cofactor of the matrix a in row 1 and column 2,  

As element of the adjoint matrix in row 2 and column 1 is cofactor of the matrix a in row 2 and column 1,

And  as element of the adjoint matrix in row 2 and column 2 is cofactor of the matrix a in row 2 and column 2.

Therefore, determinant of matrix a = (5)(-5) - (-6)(x) = -25 +30x

Thus from the formula of inverse of a matrix we get,

[tex]a^{-1}\\[/tex] = {1/( -25 +30x)} [tex]\left[\begin{array}{cc}-5&-x\\6&5\end{array}\right][/tex]

=[tex]\left[\begin{array}{cc}-5/ (-25 +30x)&-x/ (-25 +30x)\\6/ (-25 +30x)&5/ (-25 +30x)\end{array}\right][/tex] ___(2)

Therefore, equating equation (1) and (2) we get,

[tex]\left[\begin{array}{cc}-5/ (-25 +30x)&-x/ (-25 +30x)\\6/ (-25 +30x)&5/ (-25 +30x)\end{array}\right][/tex] = [tex]\left[\begin{array}{cc}5&x\\-6&-5\end{array}\right][/tex]

⇒ -5/ (-25 +30x) = 5,

-x/ (-25 +30x) = x,

6/ (-25 +30x) = -6,

and 5/ (-25 +30x) = -5

From any one of the above four equation we can equate for the value of x we get,

5/ (-25 +30x) = -5

⇒1/ (-25 +30x) = -1

⇒ 25 - 30x = 1

⇒ 30x = 24

⇒ x =24/30 = 4/5 (=0.8)

find the volume of the solid lying under the plane 8-2x-y

Answers

The volume of the solid lying under the plane 8-2x-y is 32 cubic units.

To find the volume of the solid lying under the plane 8-2x-y, you need to use a triple integral.

To find the volume, you need to perform a triple integral over the region, integrating the function 8-2x-y with respect to x, y, and z. First, find the limits of integration for x, y, and z by determining the intersections of the plane with the coordinate axes. The intersections are (4,0,0), (0,8,0), and (0,0,8). Next, set up the triple integral as follows:

∭(8-2x-y)dzdydx, with x ranging from 0 to 4, y ranging from 0 to 8-2x, and z ranging from 0 to 8-2x-y.

Evaluate the integral with respect to z first, then y, and finally x. After evaluating, you will find that the volume of the solid is 32 cubic units.
