Since p and q are real numbers, the value of q is 21.

In Mathematics and Geometry, a quadratic equation can be defined as a mathematical expression that can be used to define and represent the relationship that exists between two or more variable on a graph.

In Mathematics, the standard form of a quadratic equation is represented by the following equation;

ax² + bx + c = 0

Next, we would solve the given quadratic equation by using the completing the square method;

x² - 8x - 5 = 0

x² - 8x = 5

In order to complete the square, we would have to add (half the coefficient of the x-term)² to both sides of the quadratic equation as follows:

x² - 8x + (-8/2)² = 5 + (-8/2)²

x² - 8x + 16 = 5 + 16

x² - 8x + 16 = 21

By simplifying, we have;

The probability that all 4 people spend more than an hour a day using the Internet is 0.053 or 5.3%.

The given problem is an example of a binomial probability distribution, where there are only two outcomes - success and failure. Here, success means spending more than an hour a day using the internet, and failure means spending an hour or less a day.

The probability of success is p = 0.48, and the probability of failure is q = 1 - p = 0.52.

To find the probability that all 4 people spend more than an hour a day using the Internet, we need to use the formula for the binomial probability distribution:

Each cube has a volume of 1 cm³, and the rectangular prism contains 320 cubes, so the volume of the rectangular prism is 320 cm³.

Volume is a physical quantity that measures the amount of space occupied by an object or a substance. It is typically measured in cubic units such as cubic meters (m³) or cubic centimeters (cm³).

Here,

Length side = 4 cubes

= 5 cm

Width side = 2 cubes

= 2 cm

Height side = 2 cubes

= 2 cm

The length of the rectangular prism is 4 cubes which are equal to 5 cm each, so the length is 4 x 5 cm = 20 cm. The width of the rectangular prism is 2 cubes which are equal to 2 cm each, so the width is 2 x 2 cm = 4 cm. The height of the rectangular prism is 2 cubes which are equal to 2 cm each, so the height is 2 x 2 cm = 4 cm.

To find the volume of the rectangular prism, we multiply the length by the width by the height:

What is triangle?

A triangle is a three-sided polygon with three angles. It is a fundamental geometric shape and is often used in geometry and trigonometry.

To find the surface area of the pyramid, we need to find the area of each face and add them together.

First, let's find the area of the base, which is a square with side length 4 feet:

Area of base = 4 feet x 4 feet = 16 square feet

Next, we need to find the area of each triangular face. We know that the height of each triangular face is 6 feet, and the base of each triangular face is one of the sides of the square base, which is 4 feet. To find the area of a triangle, we use the formula:

Area of triangle = 1/2 x base x height

Area of each triangular face = 1/2 x 4 feet x 6 feet = 12 square feet

There are 4 triangular faces, so the total area of all the triangular faces is:

Total area of triangular faces = 4 x 12 square feet = 48 square feet

Now we can find the total surface area by adding the area of the base and the area of the triangular faces:

Total surface area = area of base + area of triangular faces

Total surface area = 16 square feet + 48 square feet

Total surface area = 64 square feet

Therefore, the surface area of the pyramid is 64 square feet.

Five points on the inverse function g(x) = log₄(x) are: (1, 0), (4, 1), (16, 2), (1/4, -1/2), and (2, 0.5).

Given that

f(x) = 4^x.

To find the inverse of the function f(x) = 4^x,

We need to interchange the positions of x and y and solve for y. So, we have:

x = 4^y

Taking the logarithm base 4 of both sides, we get:

y = log₄(x)

Therefore, the inverse of the function f(x) = 4^x is g(x) = log₄(x)

To find five points on the inverse function g(x), we can choose five x-values and find the corresponding y-values:

If x = 1, then g(x) = log₄(1) = 0, so the point is (1, 0).

If x = 4, then g(x) = log₄(4) = 1, so the point is (4, 1).

If x = 16, then g(x) = log₄(16) = 2, so the point is (16, 2).

If x = 1/4, then g(x) = log₄(1/4) = -1/2, so the point is (1/4, -1/2).

If x = 2, then g(x) = log₄(2) ≈ 0.5, so the point is (2, 0.5).

Therefore, five points on the inverse function g(x) = log₄(x) are: (1, 0), (4, 1), (16, 2), (1/4, -1/2), and (2, 0.5).

The resort should sell a number of 255 packages at a price of $2400 per person to maximize their monthly profit and the maximal profit is $613,400.

Maximal profit refers to the highest level of profit that a business or organization can achieve given certain constraints such as cost, demand, or pricing. It is the point at which a company or business generates the most revenue after accounting for all expenses associated with production and distribution of goods or services. To determine the maximal profit, a business will need to find the optimal balance between costs and revenue, while also taking into account factors such as competition and market demand. This involves analyzing a variety of financial metrics such as revenue, cost of goods sold, gross profit margin, and net profit margin, among others.

Let's begin by defining some variables:

P = price of the package

Q = number of packages sold

R = revenue

C = cost

Profit = revenue - cost

Based on the information given, we can create the following equations:

R = P * Q

C = 1600 + 2000 * Q

Profit = R - C = P * Q - (1600 + 2000 * Q)

We want to find the price that will maximize the monthly profit. To do this, we need to find an expression for profit in terms of P only. We can use the equation for C to substitute Q in the expression for profit:

C = 1600 + 2000 * Q

Q = (C - 1600) / 2000

Profit = P * Q - (1600 + 2000 * Q)

Profit =

Profit = P * ((C - 1600) / 2000) - C + 1600

Now we can find the derivative of profit with respect to P:

dProfit/dP = (C - 1600) / 2000

To find the value of P that maximizes profit, we need to set the derivative equal to 0:

dProfit/dP = 0

(C - 1600) / 2000 = 0

C = 1600

This means that profit is maximized when revenue equals cost, which makes sense. Substituting C = 1600 into the expression for profit, we get:

Profit = P * ((1600 + 2000 * Q - 1600) / 2000) - 1600

Profit = P * Q - 1600

Now we need to find the corresponding values of P and Q. We know that for every increase of $100 in price, there will be a decrease of 5 in the number of packages sold. This means that:

Q = 300 - (P - 2000) / 100 * 5

Substituting this into the expression for profit, we get:

Profit = P * (300 - (P - 2000) / 100 * 5) - 1600

To find the maximum profit, we can take the derivative of this expression with respect to P and set it equal to 0:

dProfit/dP = 300 - (P - 2000) / 20 = 0

P = 2400

This means that the price that will maximize the monthly profit is $2400 per person. To find the corresponding number of packages sold, we can substitute this into the equation for Q:

Q = 300 - (2400 - 2000) / 100 * 5 = 255

Therefore, the resort should sell 255 packages at $2400 per person to maximize their monthly profit. To find the maximal profit, we can substitute these values into the expression for profit:

Profit = 2400 * 255 - 1600 = $613,400.

Let's call the amount of money Andy has "x".

According to the problem, Kelly has 7 pence more than Andy, so Kelly has x + 7 pence.

Georgia has a penny less than Andy, so Georgia has x - 1 pence.

The total amount of money they have is 1.48, which we can write as 148 pence.

So we can set up the equation:

x + (x + 7) + (x - 1) = 148

Simplifying and solving for x:

3x + 6 = 148

3x = 142

x = 47.33

Since we're dealing with pence, we'll round down to the nearest whole number:

x = 47

So Andy has 47 pence, Kelly has 54 pence (47 + 7), and Georgia has 46 pence (47 - 1).

The equation of the ellipse is ((x+2)² / 36) + ((y-4)² / 35.12) = 1

To find the center of the ellipse, we can find the midpoint between the two vertices:

Midpoint = ((-8 + 4)/2, (4 + 4)/2) = (-2, 4)

So the center of the ellipse is (-2, 4).

To find the semi-major axis (a), we can find the distance from the center to one of the vertices:

Distance = √[(-8 - (-2))² + (4 - 4)²] = √36 = 6

So the semi-major axis is 6.

To find the distance between the foci (2c), we can find the distance between the two foci:

Distance = √[(-3 - (-1))² + (4 - 4)²] = 2

So 2c = 2 and c = 1.

Now we can use the relationship between a, b, and c in an ellipse:

c² = a²- b²

(1)² = (6)² - b²

b² = 35

b ≈ 5.92

So the semi-minor axis is approximately 5.92.
