Define the solution of an equation?

A solution of an equation is a value or set of values that, when substituted into the equation, makes it true. In other words, a solution is a value that satisfies the equation.

The given equation is, 4/p - 2/3q = ?-2p/3pq

or we can write as, [tex]\frac{4}{p} - \frac{2}{3q} = x - \frac{2p}{3pq}[/tex]

here find the missing term x in above equation.

Simplification,

[tex]\frac{4}{p} - \frac{2}{3q} + \frac{2p}{3pq} = x[/tex]

[tex]\frac{(4*3q)-2p}{3pq} + \frac{2p}{3pq} = x[/tex]

[tex]\frac{12q-2p}{3pq} + \frac{2p}{3pq} = x[/tex]

[tex]\frac{(12q-2p)+2p}{3pq} = x[/tex]

[tex]\frac{12q}{3pq} = x[/tex]

[tex]\frac{4}{p} = x[/tex]

Therefore, the missing term is:  [tex]\frac{4}{p}[/tex]

The events A and B are independent. Suppose P(A) = 0.25 and P(B)
= 0.45. What is the probability of either A or B occurring

Answers

The probability of either A or B occurring is 0.55625.

The probability of either A or B occurring when given that events A and B are independent, and P(A) = 0.25 and P(B) = 0.45, can be calculated as follows: 0.25 + 0.45 - 0.25*0.45= 0.55625.:

When the events A and B are independent, then the probability of the two events occurring together is given as:P(A ∩ B) = P(A) × P(B)This is a formula for independent events, and when events A and B are independent, it implies that P(A ∩ B) = 0.

Therefore:P(A ∪ B) = P(A) + P(B) - P(A ∩ B)When the probability of A and B is given as P(A) = 0.25 and P(B) = 0.45, we can substitute these values in the above equation as:P(A ∪ B) = P(A) + P(B) - P(A) × P(B)Thus:P(A ∪ B) = 0.25 + 0.45 - 0.25*0.45= 0.55625Therefore, the probability of either A or B occurring is 0.55625.

Answers

The measure of angle PQR is 50 degrees thus correct option is C) 50 degrees.

What is proportion?

A proportion is a statement that two ratios or fractions are equal. In proportion, the numerator of one fraction is proportional to the numerator of another fraction, and the denominator of one fraction is proportional to the denominator of another fraction. For example, if we have two ratios, a/b, and c/d, we can write them as a proportion as follows:

a/b = c/d

This means that the ratio of a to b is equal to the ratio of c to d. We can also write this as a fraction:

a/b = c/d = (a/b)/(c/d)

If the measure of angle PQR to the measure of angle PQS is in the ratio of 5:9, and the measure of angle PQS is 90 degrees, we can use this information to find the measure of angle PQR.

Let x be the measure of angle PQR in degrees. Then we can set up the following proportion:

5/9 = x/90

To solve for x, we can cross-multiply:

9x = 5 * 90

9x = 450

x = 50

Therefore, the measure of angle PQR is 50 degrees. Answer choice C) 50 degrees is the correct answer.

Six small and four medium bottles of lotion give a combined total of 93 fluid ounces of lotion. Which of the following pieces of information could help you determine the number of fluid ounces of lotion in a small bottle and the number of fluid ounces in a medium bottle?

Please answer this question. Giving out BRAINLIEST.This is due today, please help.

Answers

Answer is
b. 8 small and 4medium bottle

Answer:

B

Step-by-step explanation:

In answer choice B, there is the same number of medium bottles as the number of medium bottles that you are given in the question.

Because you know that there are 93 fluid ounces in six small bottles and four medium bottles, you know that any different amount of fluid ounces with the answer choice would be because of the increase in small bottles.

By having a consistent change with only one variable (which is the small bottle) you can find the rate of change. Once you figure out how many fluid ounces are in the small bottles, you can find the total amount of fluid ounces that are in the small bottles. The amount that remains is the total fluid ounces for medium bottles.

A water balloon is dropped from the second floor of a five-story building. The height in feet is modeled by f(x) = -8x^2 + 80x where x is the number of elapsed seconds. How long will the water balloon be in the air?

Answers

When A water balloon is dropped from the second floor of a five-story building, The water balloon will be in the air for 10 seconds.

To find the time the water balloon will be in the air, we need to find when the height function f(x) equals zero since this is the point at which the balloon hits the ground.

Setting f(x) = 0 and solving for x, we get:

-8x^2 + 80x = 0

=> x(-8x + 80) = 0

=> x = 0 or x = 10

Since x = 0 is the initial time when the balloon is dropped, we can discard that solution. Therefore, the water balloon will be in the air for 10 seconds.

Answers

The height of the cone is 11 mm and the slant height of the cone is 23 mm and the ant crawls 31 mm to get from the base of the cone to the top of the hill.

What is the volume of the right circular cone?

A right circular cone is a three-dimensional geometric shape that has a circular base and a vertex that is located directly above the center of the base. The axis of the cone is a line that passes through the vertex and the center of the base.

The volume of a right circular cone can be found using the formula:

[tex]V = (1/3)\pi r^2h[/tex]

where V is the volume of the cone, r is the radius of the circular base, and h is the height of the cone.

1) To find the height of the cone, we need to use the formula for the volume of a cone, which is [tex]V = (1/3)\pi r^2h[/tex]. Rearranging this formula, we get:

[tex]h = 3V / \pi r^2[/tex]

Substituting the given values, we get:

[tex]h = 3(8792) / (3.14)(20^2)[/tex]

h ≈ 11

Therefore, the height of the cone is approximately 11 mm.

2) To find the slant height of the cone, we can use the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In the case of the cone, the slant height is the hypotenuse of a right triangle formed by the height and the radius of the base. Therefore, we have:

[tex]s^2 = r^2 + h^2[/tex]

Substituting the values we found in part 1, we get:

[tex]s^2 = 20^2 + 11^2[/tex]

s ≈ 23

Therefore, the slant height of the cone is approximately 23 mm.

3) To find the distance the ant crawls to get from the base of the cone to the top of the hill, we can use the Pythagorean theorem again. This time, we need to find the distance along the slant height from the base of the cone to the top of the hill. This distance is the hypotenuse of a right triangle formed by the distance from the base to the apex (which is the height of the cone) and the radius of the base. Therefore, we have:

[tex]d^2 = r^2 + s^2[/tex]

Substituting the values we found in parts 1 and 2, we get:

[tex]d^2 = 20^2 + 23^2[/tex]

d ≈ 31

Therefore, the ant crawls approximately 31 mm to get from the base of the cone to the top of the hill.

Complete the table. Enter your answers in the boxes.

Answers

There are 44 Democratic senators and no Independent senators based on ratio.

Since the ratio of Republicans to Democrats is 5:4, we can represent the number of Republican senators as 5x and the number of Democratic senators as 4x, where x is a positive integer. The total number of senators is given as 100, so we have:

5x + 4x + Independent = 100

Simplifying:

9x + Independent = 100

To find the values of x and Independent, we need to solve for these variables. We can start by subtracting Independent from both sides of the equation:

9x = 100 - Independent

Now, we need to find a value of x that makes the right-hand side of the equation divisible by 9. Since the sum of the digits of 100 is 1 + 0 + 0 = 1, which is not divisible by 9, we need to find a value of Independent that makes the sum of the digits of 100 - Independent divisible by 9. The only value that works is Independent = 1, which gives us:

9x = 99

x = 11

Now we can substitute this value of x back into the equation to find the number of Republican and Democratic senators:

Republican = 5x = 5(11) = 55

Democrat = 4x = 4(11) = 44

Answers

Answer: The equation of a line can be written in slope-intercept form as:

y = mx + b

where m is the slope and b is the y-intercept.

We are given that the line has a slope of -3 and passes through the point (2, 2). We can use the point-slope form of the equation of a line to find the equation of this line:

y - y1 = m(x - x1)

where (x1, y1) is the given point and m is the slope.

Substituting the given values, we get:

y - 2 = -3(x - 2)

Expanding the right side:

y - 2 = -3x + 6

Adding 2 to both sides:

y = -3x + 8

Therefore, the equation of the line that has a slope of -3 and passes through the point (2, 2) is:

y = -3x + 8.

Answer: f(x,y)=e^(ax+by) with a^2+b^2=1. Prove that : f''(xx)+f''(yy)=1

Answers

Proved that if the function f(x,y)=e^(ax+by) with a^2+b^2=1, then f''(xx)+f''(yy)=1

To find the second partial derivatives of f(x, y), we differentiate f(x, y) twice with respect to x and y:

f'(x, y) = ae^(ax + by) and f''(xx) = a^2e^(ax + by)

f'(x, y) = be^(ax + by) and f''(yy) = b^2e^(ax + by)

Adding these second partial derivatives, we get:

f''(xx) + f''(yy) = a^2e^(ax + by) + b^2e^(ax + by)

Since a^2 + b^2 = 1, we have:

f''(xx) + f''(yy) = e^(ax+by)

But f(x, y) = e^(ax+by), so:

f''(xx) + f''(yy) = f(x, y)

Therefore, we have proved that f''(xx) + f''(yy) = 1.

Trevor's stack of books is 7 7/8 inches tall. Rick's stack is 3 times as tall. What is the difference in the heights of their stacks of books?​

Answers

For rectangle type books,  the difference in the heights of their stacks of books is 15 3/4 inches.

What exactly is a rectangle?

A rectangle is a type of quadrilateral (a four-sided polygon) that has four straight sides and four right angles. It is a two-dimensional shape, meaning it lies flat in a plane, and is defined by its two sets of parallel sides, each pair of which are equal in length.

In a rectangle, opposite sides are parallel and congruent (equal in length), and adjacent sides are perpendicular (meet at a right angle). The diagonals of a rectangle bisect each other (divide each other into two equal parts) and are congruent.

The area of a rectangle is calculated by multiplying its length and width, while its perimeter is found by adding the lengths of all its sides. The formula for the area of a rectangle is A = l x w, where A is the area, l is the length, and w is the width. The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.

Now,

To solve this problem, we need to first find out the height of Rick's stack of books. We know that his stack is 3 times as tall as Trevor's stack, so:

Rick's stack = 3 x Trevor's stack

Rick's stack = 3 x 7 7/8 inches

Rick's stack = 23 5/8 inches

Now that we know the height of both stacks, we can find the difference between them:

Difference = Rick's stack - Trevor's stack

Difference = 23 5/8 inches - 7 7/8 inches

Difference = 15 6/8 inches

Difference = 15 3/4 inches

Therefore, the difference in the heights of their stacks of books is 15 3/4 inches.

A square has four equal sides and four right angles. It is a special type of rectangle, and like rectangles, it is also a two-dimensional shape with all its sides lying in a plane.

A square has several important properties. Its sides are equal in length, and its diagonals are congruent (equal in length) and bisect each other at right angles. All angles in a square are also right angles, which means that it is a special type of rectangle where all angles measure 90 degrees.

The area of a square is calculated by squaring the side. For example, if a square has a side length of s, its area would be A = s². The perimeter of a square is found by adding up the lengths of all four sides, which is P = 4s.

Now,

The sides of the squares will be 2m, 2m and 1 m.

then area of the figure will be =2²+2²+1²

What is the probability that a randomly selected unicyclist from Corvallis, OR. Is not between 30 and 39?

Answers

The probability that an arbitrarily chosen Corvallis unicyclist is not between the ages of 30 and 39 is roughly 0.995, or 99.5%.

To find the probability that a randomly selected unicyclist from Corvallis is not between 30 and 39, we need to first determine the total number of unicyclists in Corvallis. We can find this by summing up the frequencies for all age groups:

Total number of unicyclists = 16 + 86 + 1 + 1 + 68 + 15 + 14 = 201

Next, we need to determine the frequency of unicyclists who are not between 30 and 39. We can do this by adding up the frequencies for all age groups that are not between 30 and 39:

Frequency of unicyclists not between 30 and 39 = 16 + 86 + 1 + 68 + 15 + 14 = 200

Finally, we can calculate the probability of selecting a unicyclist who is not between 30 and 39 by dividing the frequency of unicyclists not between 30 and 39 by the total number of unicyclists:

P(not between 30 and 39) = Frequency of unicyclists not between 30 and 39 / Total number of unicyclists

P(not between 30 and 39) = 200 / 201

P(not between 30 and 39) ≈ 0.995

Therefore, the probability that a randomly selected unicyclist from Corvallis is not between 30 and 39 is approximately 0.995 or 99.5%.

What is AP?

Arithmetic Progression (AP) is a sequence of numbers in which the difference between the two consecutive numbers is always the same. Each number in the sequence is called a term of the progression. It is a type of sequence where the difference between consecutive terms is constant.

The given expression is an arithmetic progression (AP), in which the common difference between consecutive terms is 7. An AP is a sequence of numbers where each term after the first is formed by adding a fixed value to the preceding one.

The first term of the AP is given as a_1=-54 and the common difference (d) is 7. Thus, the nth term of the given AP can be found using the formula a_n = a_1 + (n-1)d. Substituting the values in this formula, we get a_n = -54 + (n-1)7.

Therefore, the nth term of the given AP is a_n = -54 + (n-1)7.

For example, if n = 10, then the 10th term of the given AP is a_10 = -54 + (10-1)7 = -54 + 63 = 9.

To determine whether (3, 20) is a solution of y = 4x + 8, we need to substitute x = 3 and y = 20 into the equation and check whether the equation is true:

y = 4x + 8

20 = 4(3) + 8

20 = 12 + 8

20 = 20

Since the equation is true, we can say that (3, 20) is a solution of y = 4x + 8.

Answer:

Step-by-step explanation:

y= 4x+8

substituting x=3,

y= 4(3)+8

y= 12+8

y=20

∴ (3,20) is a solution of y= 4x+8

If A and B are two mutually exclusive events with P(A)=0.45 and P(B)=0.45 , find the following probabilities: a) P(A and B)= b) P(A or B)= c) P(notA)= d) P(notB)= e) P(not(A or B))= f) P(A and ( not B))= Note: You can earn partial credit on this problem. You have attempted this problem 0 times. You have unlimited attempts remaining.

Answers

The probabilities of the events are:

a) P(A and B) = 0

b) P(A or B)  = 0.9

c) P(notA) = 0.55

d) P(notB) = 0.55

e) P(not(A or B)) = 0.1

f) P(A and (not B)) = 0.45

How to find the probability of A and B?

Probability is the measure of the likelihood or chance of an event occurring. It deals with the study of random events and the analysis of their outcomes.

Since A and B are mutually exclusive, they cannot happen at the same time. This means that P(A and B) = 0.

a) P(A and B) = 0

b) P(A or B) = P(A) + P(B)

P(A or B) = 0.45 + 0.45 = 0.9

c) P(notA) = 1 - P(A)

P(notA) = 1 - 0.45 = 0.55

d) P(notB) = 1 - P(B)

P(notB) = 1 - 0.45 = 0.55

e) P(not(A or B)) = 1 - P(A or B)

P(not(A or B)) = 1 - 0.9 = 0.1

f) P(A and (not B)) = P(A) - P(A and B)

P(A and (not B)) = 0.45 - 0 = 0.45

Find the smallest and largest value of the function [tex]y=3x^2-x^3[/tex]

Answers

The smallest value οf the functiοn is negative infinity, and the largest value is 8.

The functiοn [tex]y = 3x^2 - x^3[/tex] is a cubic functiοn. Tο find the smallest and largest values οf this functiοn, we can take the derivative and find where it equals zerο οr dοes nοt exist. At these pοints, the functiοn will have lοcal extrema (either a maximum οr minimum).

[tex]y = 3x^2 - x^3[/tex]

[tex]dy/dx = 6x - 3x^2[/tex]

Setting the derivative equal tο zerο, we get:

6x - 3x^2 = 0

3x(2 - x) = 0

Sο the critical pοints are at x = 0 and x = 2.

Tο determine whether these critical pοints cοrrespοnd tο a lοcal maximum οr minimum, we can use the secοnd derivative test. Taking the secοnd derivative οf the functiοn, we get:

[tex]d^2y/dx^2 = 6 - 6x[/tex]

At[tex]x = 0, d^2y/dx^2 = 6[/tex], which is pοsitive, sο this critical pοint cοrrespοnds tο a lοcal minimum. At[tex]x = 2, d^2y/dx^2 = -6[/tex], which is negative, sο this critical pοint cοrrespοnds tο a lοcal maximum.

Tο find the smallest and largest values οf the functiοn, we need tο evaluate the functiοn at these critical pοints and at the endpοints οf the interval οf interest. The interval οf interest is nοt specified, sο we will assume that we want tο find the smallest and largest values οver the entire real line.

y(-∞) = -∞ (as x apprοaches negative infinity, y apprοaches negative infinity)

y(0) = 0

y(2) = 8

y(∞) = -∞ (as x apprοaches infinity, y apprοaches negative infinity)

Therefοre, the smallest value οf the functiοn is negative infinity, and the largest value is 8.

4. Joey is trying to determine the volume of his toy box. He is able to

completely fill the base of the toy box with eight 1-inch cubes. After

creating 2 more layers, the entire toy box is filled. What is the volume of his

toy box?

Answers

The volume of Joey's toy box is 24 cubic inches.

If the base of the toy box is filled with 8 1-inch cubes, then the volume of the base is:

Volume of base = 8 cubes x [tex](1 inch/cube)^3[/tex] = 8 cubic inches

If the toy box has two more layers on top of the base, then it has a total of three layers. Let's call the height of each layer "h". Then the total height of the toy box is:

Total height = 3h

The volume of each layer is the same as the volume of the base, which is 8 cubic inches. Therefore, the volume of the entire toy box is:

Volume of toy box = volume of base + volume of 2 layers

Volume of toy box = 8 cubic inches + 2(8 cubic inches)

Volume of toy box = 8 cubic inches + 16 cubic inches

Volume of toy box = 24 cubic inches

Therefore, the volume of Joey's toy box is 24 cubic inches.

Find the rate of change of given functions. (a) [6pt] \( f(x)=-5 x^{2}+3 x-7 \) (a) (b) [8pt] \( g(x)=\frac{-5 x+7}{2 x-3} \) (b)

Answers

The rate of change of each given function are:

f(x) = 5x² + 3x - 7; f'(x) = 10x + 3g(x) = [tex]\frac{-5x + 7}{2x - 3}[/tex]; [tex]g'(x)=\( \frac{-10x+11}{(2x-3)^2} \)[/tex]

To find the rate of change of given functions, we have to differentiate the given function w.r.t the variable provided. We will solve each part of the question and differentiate the functions step by step.

(a) f(x) = 5x² + 3x - 7

The function is, f(x) = 5x² + 3x - 7

Differentiating the above function, we get;

f'(x) = (5x² + 3x - 7)/dx

f'(x) = 10x + 3

Therefore, the rate of change of function f(x) = 5x² + 3x - 7 is 10x + 3.

Now, let us solve the second part of the question.

(b)[tex]\( g(x)=\frac{-5 x+7}{2 x-3} \)[/tex]

The function is,[tex]\( g(x)=\frac{-5 x+7}{2 x-3} \)[/tex]

Differentiating the above function using the quotient rule, we get;

[tex]\[\begin{aligned} g'(x)&=\frac{(2x-3)\cdot (-5)-(7)\cdot(2)}{(2x-3)^2}\\ &=\frac{-10x+11}{(2x-3)^2}\end{aligned}\][/tex]

Therefore, the rate of change of function [tex][tex]\( g(x)=\frac{-5 x+7}{2 x-3} \) is \( \frac{-10x+11}{(2x-3)^2} \).[/tex][/tex]
