Gong must have driven the truck for 149 miles as per the given problem.

Let’s discuss the problem in detail.

In addition to the base rate of $19.95, there was an extra fee of 71 cents for every mile driven. When Gong returned the truck, he was required to pay $125.74.

Now we have to calculate how far did he drive the truck before stopping.

First, let’s convert all dollars into cents.

Base fee = 1995 cents.

71 cents for each mile.

Total Gong gave 12574 cents.

Assume Gong drive for x miles.

Therefore,  12574 = 1995 + 71 * x

= 71x = 12574 - 1995

= 71x = 10579

= x = 10579/71 = 149 miles.

Hence, Gong drove the truck for 149 miles before stopping.

The binary number system or base two number system is a system of writing numbers using two symbols, namely 0 and 1.The modern binary number system was discovered by Gottfried Wilhelm Leibniz in the 17th century. This number system is the basis of all digital-based number systems. From the binary system, we can convert it to the Octal or Hexadecimal number system. We can also refer to this system as Bits, or Binary Digits. Binary groupings on a computer always add up to 8, with the term 1 Byte/byte. In computer terms, 1 Byte = 8 bits. Computer design codes, such as ASCII, American Standard Code for Information Interchange use a 1 Byte coding system.

In modern digital communication systems, where data is transmitted in the form of binary bits, a system is needed that is resistant to noise contained in the transmission channel so that the transmitted data can be received correctly. Errors in sending or receiving data are fundamental problems that have a very significant impact on communication systems.[2] The commonly used binary has 8 digit numbers and only contains the numbers 1 and 0, no other numbers.

The mass of the marble in kg is 486 kg .

Now, According to the question:

A sculptor needs to lift a piece of marble.  

It is a cuboid with dimensions 1 m by 0.6 m by 0.3 m.  

Marble has a density of 2.7 g/cm³.

We need to find what is the mass of the marble in kg .

Let's find out :

Volume of Cuboid = Length × Width × Height

Volume = (1m)(0.6m)(0.3m)

Volume = 0.18[tex]m^3[/tex]

Also , We know that

Density = [tex]\frac{Mass}{Volume}[/tex]

Density = 2.7[tex]\frac{g}{cm^3}[/tex]

Density = 2.7 [tex]\frac{10^-^3kg}{(10^-^2m)^3}[/tex]

Density = 2.7[tex]\frac{10^-^3kg}{(10^-^6m)}[/tex]

Density = 2.7[tex](10^-^3^+^6)kgm^-^3[/tex]

Density = 2.7[tex](10^6)kgm^-^3[/tex]

Now, Density = [tex]\frac{Mass}{Volume}[/tex]

2.7[tex](10^6)[/tex] = [tex]\frac{Mass}{0.18}[/tex]

Mass = [tex]2.7(10^6)[/tex] × 0.18

Mass = 486kg

Therefore , the mass of the marble in kg is 486 kg .

The Pythagorean Triplets states that in any right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two legs of the right triangle. The Pythagorean Triplets is (3,4,5).

Pythagorean triplets:

The Pythagorean numbers consist of three positive integers a, b, and c such that a2 + b2 = c2. Such triples are usually written as (a, b, c), with a familiar example being (3, 4, 5). If (a, b, c) are Pythagorean numbers, then (ka, kb, kc) for all positive integers k. A primitive Pythagorean number is one in which a, b, and c are relatively prime (that is, they have no common divisors greater than 1). For example, (3, 4, 5) is a primitive Pythagorean number, but (6, 8, 10) is not. A triangle whose sides form a Pythagorean triple is called a Pythagorean triangle and is always a right triangle.

Based on the Question:

Let the smallest even number be 2m

(i) (3,4,5)

  2m = 4

⇒ m = 2

⇒ m² −1 = 4−1 = 3

⇒ m² +1 = 4+1 = 5

∴(3,4,5) is a Pythagorean triplet.

(ii) (10,24,26)

  2m = 10

⇒ m = 5

⇒ m²−1 = 25−1 = 24

⇒ m²+1 = 25+1 =26

∴(10,24,26) is not a Pythagorean triplet.

(iii) (6,7,8)

  2m = 6

⇒ m = 3

⇒ m² −1 = 9−1 = 8

⇒ m² +1 = 9+1 = 10

∴(6,7,8) is not a Pythagorean triplet.

(iv) (2,3,4)

2m=2

⇒m=1

m² −1 = 1−1 = 0

m²+1 = 1+1 = 2

∴(2,3,4) is not a Pythagorean triplet.

We can use the Law of Cosines. The Law of Cosines states that for a triangle ABC with sides a, b, and c, and angle A opposite side c, the measure of angle A can be found: cos A = (b^2 + c^2 - a^2) / (2bc)

Measure or determine the lengths of all three sides of the triangle (a, b, and c). Let's say a = 5, b = 6, and c = 7.

Substitute the side lengths into the formula above and solve for cos A. cos A = (6^2 + 7^2 - 5^2) / (267) = 0.6

Use the inverse cosine function to find the measure of angle A in degrees or radians. In this case, A = 60 degrees.

To find the length of side HI in triangle HIG, we can use the Pythagorean Theorem. The Pythagorean Theorem states that for any right triangle, the length of the hypotenuse (the side opposite the right angle) is equal to the square root of the sum of the squares of the other two sides.

Measure or determine the lengths of the two legs of the triangle (HG and GI). Let's say HG = 8 and GI = 6

Substitute the side lengths into the formula HI^2 = HG^2 + GI^2 and solve for HI. HI = √(8^2 + 6^2) = √(64+36) = √100 = 10

Therefore, the length of side HI is 10.

The formula of an image in a straight line is y = mx + c, where m is the slope of the line, x is the x-coordinate of the point and c is the y-intercept.

A straight line is a line whose points all lie in the same plane and all have the same distance from each other, making them all equidistant. The line does not curve or bend in any way, and can extend infinitely in either direction. Straight lines are the most basic form of geometric shape and are the foundation of all other shapes. The line is defined by two points, known as its endpoints, and any point that lies on the line is called a point on the line. Straight lines are important in mathematics, as they are used to describe relationships between points on a graph, and they can also be used to define equations and boundaries.

The y-intercept is the point at which the line crosses the y-axis. The slope of the line is determined by the ratio of the change in the y-coordinate to the change in the x-coordinate. To calculate the slope of a line, the formula m = (y2 - y1)/(x2 - x1) is often used, where (x1, y1) and (x2, y2) are two points on the line. Using the slope and the y-intercept, the formula can be used to plot the points of the image along a straight line.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

The values on the table can be represented as:

(x, g(x)) = (-3, 0.375) (-1, 0.75) (1, 1.5) (3, 3) (5, 6) (7,12) (9, 24)

The above values show that as the values of x increases by 2, the values of function g(x) doubles.

Only an exponential function has this property.

Hence, the table of values represents an (a) exponential function.
