The ellipse's equation is [tex]$\frac{x^2}{3^2}+\frac{y^2}{4^2}=1$[/tex] , The hyperbola's equation is [tex]$ \frac{x^2}{(-4)^2}-\frac{y^2}{(-7)^2}=1$[/tex] and  [-3, 3] is the ellipse's domain.

The ellipse's equation is (Part A) [tex]$\frac{x^2}{3^2}+\frac{y^2}{4^2}=1$[/tex] , The hyperbola's equation is shown in Part B as [tex]$ \frac{x^2}{(-4)^2}-\frac{y^2}{(-7)^2}=1$[/tex]

Part C: [-3, 3] is the ellipse's domain.

The hyperbola's domain lies between [-, -4].

The ellipse and hyperbola's domains do not intersect, hence the system of equations cannot be solved. The origin is the location of the ellipse's centre;8 units make up the vertical main axis. The minor axis equals six units.

Here is a general representation of the ellipse equation:;[tex]$\frac{x^2}{b^2}+\frac{y^2}{a^2}=1$[/tex]

a= The semi-major axis, where 8/2 = 4.

The semi-minor axis, b= 6/2 = 3.

Therefore, the ellipse's equation is

[tex]${\frac{-x^2}{3^2}+\frac{y^2}{4^2}=1}$[/tex]

The negative vertex and the domain of the hyperbola are equal.

∴ The hyperbola's domain is [x -4] = [-, -4]

The inequality of p is p < 10

From the question, we have the following parameters that can be used in our computation:

Total amount = $140

Coupon = $20

Number of people = 12

The inequality of p is then represented as

p < (Total amount - Coupon)/Number of people

Substitute the known values in the above equation, so, we have the following representation

p < (140 -20)/12

Evaluate

p < 10

After addition, 3/5 + 2/7 can be expressed as a fraction as 31/35.

Math is not complete without fractions. The same fundamental procedures that may be applied to integers also apply to fractions. To solve the given problem, we need to add the given fractions using the common denominator property of fractions.

The Least Common Multiple (LCM) of 5 and 7 is 35. Hence, the common denominator is 35.

So, 3/5 + 2/7 = (3 × 7) / (5 × 7)  + (2 × 5) / (7 × 5)

                    = 21/35 + 10/35

Correct options are B, E. The point (0, -5) lies on the graph. The function is undefined for x = 1.

The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x.

In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The range is made up of all values that the function's output can take.

The three (3) statements which are true include the following:

A. The radius of the circle is 3 units.

B. The center of the circle lies on the x-axis.

D. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

In Mathematics, the standard form of the equation of a circle is represented by this mathematical expression;

(x - h)² + (y - k)² = r²   ....equation 1.

Where:

From the information provided above, we have the following equation of a circle:

x² + y² – 2x – 8 = 0      ......equation 2.

In order to determine the true statements, we would rewrite the equation in standard form and then factorize by using completing the square method:

x² – 2x + y² = 8 = 0

x² – 2x + (2/2)² + y² = 8 + (2/2)²

x² – 2x + 1 + y² = 8 + 1

(x – 1)² + (y - 0)² = 9         .......equation 3.

Comparing equation 1 and equation 3, we have the following:

Center (h, k) = (1, 0)

Radius (r) = 3

Additionally, this line and the center of the given circle lies on the x-axis (x-coordinate) because the y-value is equal to zero (0).

(x – 0)² + (y - 0)² = 3²

x² + y² = 9.

Answer:

To calculate the volume of a triangular pyramid, we can use the formula:

V = (1/3) * B * h

where V is the volume, B is the area of the base, and h is the height of the pyramid.

Since the base of the pyramid is a right-angled triangle, we can use the Pythagorean theorem to find the length of the other two sides, which are the legs of the triangle. The hypotenuse is 6 cm and the angle opposite to the hypotenuse is 30°, so we can use the sine function to find the length of the other leg:

sin(30) = opposite / hypotenuse

opposite = (sin(30) * hypotenuse) = (1/2 * 6) = 3

Now we can use the area formula for a right-angled triangle:

B = (1/2) * base * height = (1/2) * 3 * 6 = 9

To find the height of the pyramid, we can use the fact that all side faces form an angle of 60° with the base. We can use the sine function to find the height of the pyramid:

sin(60) = opposite / hypotenuse

opposite = (sin(60) * hypotenuse) = (√3/2 * 6) = 3√3 cm

Now we can substitute the values of B and h into the volume formula:

V = (1/3) * B * h = (1/3) * 9 * 3√3 = 3√3 cm³

So the exact volume of the triangular pyramid is 3√3 cm³.

Simon's age is 18.

Step-by-step explanation:

Let Simons age be s and the age of each twin be t.

s + 2t = 48

s - t = 3

Subtract the second equation from the first:

s - s + 2t - (-t) = 45

2t + t = 45

3t = 45

t = 45/3 = 15.

Now we find Simon's age by plugging t = 15 in the second equation:

s - t = 3

s - 15 = 3

s = 3 + 15 = 18.

Account B has more money than account A. Then account that has the greater principal will be account B.

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

The formula for interest is written as,

I = (PRT)/100

Where P is the principal, R is the rate of interest, and T is the time.

Dakota procured $10.50 in revenue in Record An and $35.00 in revenue in Record B following 21 months. In the event that the straightforward financing cost is 3% for Record An and 5% for Record B.

Then the account has the greater principal will be given as,

10.50 = [P₁ x 3 x (21/12)] / 100

1050 = 5.25P₁

P₁ = $200

The commutative property applies only to addition and multiplication of real numbers.

What is commutative property in math?

This law simply states that with addition and multiplication of numbers, you can change the order of the numbers in the problem and it will not affect the answer. Subtraction and division are NOT commutative.

so as ask in question that, does the commutative property apply to all real numbers?

The commutative property applies to addition and multiplication of real numbers, meaning that a + b = b + a and a * b = b * a for any real numbers a and b.

However, it does not apply to subtraction or division, meaning that a - b ≠ b - a and a / b ≠ b / a for all real numbers a and b.

Therefore, the commutative property applies only to addition and multiplication of real numbers.

When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself.

Range, which shows statistical dispersion, is the size of the smallest interval in descriptive statistics that encompasses all the data. It is best suited to capturing the dispersion of tiny data sets because it only depends on two observations.

Answer: -3/2

Step-by-step explanation:

To find the slope of the line perpendicular to the given one, we first need to change the equation to y=mx+b to find the original slope.

[tex]6x-9y=216[/tex]             [subtract both sides by -6x]
[tex]-9y=-6x+216[/tex]        [divide both sides by -9]
[tex]y=\frac{2}{3} x-24[/tex]

Now we know slope is 2/3. The slope of the perpendicular line is the opposite sign and reciprocal of the slope.

Opposite would make it -2/3.

Reciprocal would be -3/2.
So the slope is -3/2.
