all points on the dotted line are not included but all points on the solid line are included.

To show that there are infinitely many rational numbers between any two real numbers x and y, where x< y, we can use the Archimedean property of the real numbers.

The Archimedean property states that for any two positive real numbers a and b, there exists a positive integer n such that na>b. Let's choose a positive integer n such that 1/n< y-x. Then we can divide the interval(x,y) into n subintervals of equal length:

(x, y) = (x, x + (y - x)/n) ∪ (x + (y - x)/n, x + 2(y - x)/n) ∪ ... ∪ (x + (n - 1)(y - x)/n, y).

Each of these intervals  has length(y-x)/n, which is less than 1/n. therefore, there must be at least one integer k such that x+k(y-x) is a rational number. This is because the numerator k(y-x) is an integer, and the denominator n is a positive integer.Since there are n subintervals, we have found at least n different rational numbers between x and y.

However, since the choice of n was arbitrary we can choose a larger n to find even more rational numbers between x and y. Therefore, there must be infinitely many rational numbers between x and y.

Let x and y be reals with x<y. Show that there are infinitely many rationals b such that x<b<y.

B. After 24 hours, approximately 2.49 grams will be left.

C. After approximately 18.13 hours, there will be approximately one gram left.

A. To represent the number of grams present after n hours, we can use the equation:

N(n) = 15 × (1 - 0.2)^n

Where:

N(n) is the number of grams present after n hours,

15 is the initial amount of the substance in grams,

0.2 represents the decay rate of 20% per hour, and

^n represents the exponentiation operation.

B. To find out how much will be left after 24 hours, we can substitute n = 24 into the equation from part A:

N(24) = 15 × (1 - 0.2)^24

Calculating this expression, we find that approximately 2.49 grams will be left after 24 hours.

C. We need to determine the number of hours it takes until there is approximately one gram left. We can set up the equation:

1 = 15 × (1 - 0.2)^n

To solve for n, we can divide both sides of the equation by 15 and then take the logarithm (base 0.8) of both sides:

log(0.8)(1/15) = n

Using a calculator or logarithmic properties, we find that approximately 18.13 hours are required until there is approximately one gram left.

Therefore, the answers are:

B. After 24 hours, approximately 2.49 grams will be left.

C. After approximately 18.13 hours, there will be approximately one gram left.

Cartesian Equation: y = √(1 - x^2)

Graph: Second one

Step-by-step explanation:

x^2 = sin^2(θ/2),

y^2 = cos^2(θ/2),

According to that theory, by the circle equation, x^2 + y^2 = 1^2.

When θ = -π, x = sin(-π/2) = - 1, and y = cos(-π/2) = 0

When θ = π, x = sin(π/2) = 1, and y = cos(π/2) = 0

The radius is 1 in this case, (x^2 + y^2 = r^2 -> x^2 + y^2 = 1^2 -> x^2 + y^2 = 1) as the semicircle ranges from (- 1, 0) to (1,0). Therefore your graph is the second one;

When theta = 0, x = sin 0 = 0, and y = cos 0 = 1, so the semicircle passes through (0, 1). To determine the equation, let's simply isolate "y" in the equation x^2 + y^2 = 1^2,

In Cartesian form, the equation is  y = √(1 - x^2)

Answer:

0

Step-by-step explanation:

The smallest (greater or equal to zero) multiple of 13 is 0

to get a positive multiple of 13 you have to multiply 13 by a natural number:

0 = 13×0

13 = 13×1

26 = 13×2

.

.

then the smallest one is 0.

A point which is relative maxima on the interval x = –1 and x = 1 in the graph is point a.

In Mathematics and Geometry, a relative maxima can be defined as a maximum point on the graph of a function which is typically higher than the points that are directly close (beside) to it on both sides or over a specific interval on the x-coordinate (x-axis).

This ultimately implies that, a relative maxima refers to the maximum point on the graph of a function over a short (minimal) interval.

By critically observing the graph of a function, we can logically deduce that point a at the origin (0, 0) is the only point that represents relative maxima on the interval x = –1 and x = 1.

FOR PART 2;

She will make $10.50 and still owe you $5.25 for the payback. Option B is correct.

Given that,
Borrowed money for the initial supplies, which cost a total of $15.75. She plans to charge $0.35 for each glass of iced tea.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Total money borrowed = $15.75
cost per glass of ice tea = $0.35
Total cost for 30 glasses of tea = 0.35 * 30 = $10.5
So she will pay the pack $10.5
Remaining money = 15.75 - 10.5 = 5.25

Thus, she will make $10.50 and still owe you $5.25. Option B is correct.

Answer:

V = 9.75 cubic inches.

Step-by-step explanation:

Given the following data;

Length = 2 inches

Width = 3¼ inches

Height = 1½ inches

To find the volume of rectangular prism;

Volume of rectangular prism = length * width * height

V = 2 * 3¼ * 1½

V = 2 * 13/4 * 3/2

V = 2 * 39/8

V = 2 * 4.875

V = 9.75 cubic inches

The value x in the secant line using the Intersecting theorem is 4.

Intersecting secants theorem states that " If two secant line segments are drawn to a circle from an exterior point, then the product of the measures of one of secant line segment and its external secant line segment is the same or equal to the product of the measures of the other secant line segment and its external line secant segment.

From the figure:

First sectant line segment = ( x - 1 ) + 5

External line segment of the first secant line = 5

Second sectant line segment = ( x + 2 ) + 4

External line segment of the second secant line = 4

Using the Intersecting secants theorem:

5( ( x - 1 ) + 5 ) = 4( ( x + 2 ) + 4 )

Solve for x:

5( x - 1 + 5 ) = 4( x + 2 + 4 )

5( x + 4 ) = 4( x + 6 )

5x + 20 = 4x + 24

5x - 4x = 24 - 20

x = 4

Therefore, the value of x is 4.

Option C) 4 is the correct answer.

The triangle is not a right triangle because the Pythagorean Theorem (c² = a² + b²) is not satisfied.

What is the Pythagorean Theorem?

Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named Perpendicular, Base, and Hypotenuse.

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side, which is opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In this case, the given values of a and b do not satisfy the equation:

c² = a² + b²

(86)² = (76.5)² + (40.1)²

7396 = 5862.25 + 1608.01

7396 = 7470.26

This means that the triangle with sides a = 76.5 yd, b = 40.1 yd, and c = 86 yd is not a right triangle.

Hence, The triangle is not a right triangle because the Pythagorean Theorem (c² = a² + b²) is not satisfied.

Answer:

y = -5/2x + 27/2

Step-by-step explanation:

line formula is y = mx + b

perpendicular means number next to the x (slope or m) becomes a negative reciprocal

2/5x -> -5/2x

then use point slope formula

y - y1 = m (x - x1)

y - 6 = -5/2 (x - 3)

y - 6 = -5/2x + 15/2

y = -5/2x + 15/2 + 6

y = -5/2x + 15/2 + 12/2

y = -5/2x + 27/2

The total cost of the liquid in the spherical tank is $ 6782.40

What is a Sphere?

A sphere has a spherical, symmetrical shape. It is a three-dimensional solid with equal distances between each surface point and the center. On the basis of its radius, it has a surface area and a volume. There are no faces, corners, or edges on it.

The volume of a sphere is given by the formula

Volume of Sphere = ( 4/3 )πr³

where r is the radius of the sphere

Given data ,

Let the total cost of the liquid in the spherical tank be = A

Let the radius of the spherical tank be = R

The value of R = 6 yards

Now the cost of the liquid in the tank per cubic yard = $ 7.50

And ,

The volume of spherical tank = ( 4/3 )πR³

Substituting the values in the equation , we get

The volume of spherical tank = ( 4/3 ) x 3.14 x ( 6 )³

The volume of spherical tank = 25.12 x 6 x 6 x 6

The volume of spherical tank = 904.32 yards³

Now ,

The total cost of the liquid inside the spherical tank A = cost of the liquid in the tank per cubic yard x volume of spherical tank

Substituting the values in the equation , we get

The total cost of the liquid inside the spherical tank A = 7.50 x 904.32

The total cost of the liquid inside the spherical tank A = $ 6782.40

Therefore , the value of A is $ 6782.40

Hence , the volume of sphere is 904.32 yards³ and the cost of the liquid inside the tank is $ 6782.40
