The value of the modulus function is g ( x ) = | x | - 4

Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.

It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.

The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:

If x is positive, then f(x) = x

If x = 0, then f(x) = 0

If x < 0, then f(x) = -x

Given data ,

Let the absolute value function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = | x |   be equation (1)

Now , the function f ( x ) is shifted vertically down by 4 units

Down by d units: y = f(x) - d

Substituting the values in the equation , we get

Let the translated function be represented as g ( x )

g ( x ) = f ( x ) - 4

On simplifying the equation , we get

g ( x ) = | x | - 4

Hence , the transformed function is g ( x ) = | x | - 4

The greater angle has a measurement of 152 degrees. The smaller angle has a measurement of 28 degrees.

An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle. Angles created by two rays are located in the plane containing the rays. Angles are also generated when two planes intersect. These are known as dihedral angles. An angle is formed by joining two rays (half-lines) that have a shared terminal. The latter is referred to as the angle's vertex, while the rays are referred to as the angle's sides, legs, and arms. An angle is a figure in Plane Geometry generated by two rays or lines that share a common endpoint.

When adding or subtracting numbers, the number of digits in the result must be equal to the smallest number of digits after the decimal point of a term in the sum. How closely a measured value agrees with a reference or known value is referred to as accuracy. For example, if you get a weight measurement of 3.2 kg for a substance in a laboratory, but the actual or known weight is 10 kg, your measurement is not accurate.In this case, your measurement is nowhere near the known value.

Step-by-step explanation:

The probability that both students pick the same tire is (1/4) * (1/4) = 1/16

The probability of the first student picking a specific tire is 1 in 4, or 1/4. The probability of the second student also picking that same tire is also 1 in 4. To find the probability that both students pick the same tire, we need to multiply the probabilities of each event.

So, the probability that both students pick the same tire is (1/4) * (1/4) = 1/16. This means that the chance of both students picking the same tire is 0.0625 or 6.25%.

To summarize, there are four possible tires that could have gotten a flat, and two students are asked to identify the tire. If each student randomly chooses a tire, the probability that both students will pick the same tire is 1 in 16, or 0.0625. This means that the chance of both students picking the same tire is low, and the likelihood of them choosing different tires is much higher.

Plugging this in,

lim (h->0)8+12h +6h²+ h³-8 / h = lim (h->0) 12h +6h²+ h³ / h

The number of divisors of 1730 of the form 4n + 1 is 20.

An integer is a whole number, meaning it can be positive, negative, or zero, but it cannot be a fraction or a decimal. Integers are a subset of real numbers, which also include fractional and decimal numbers.

Integers are commonly used in mathematics and computer science for counting and for performing arithmetic operations such as addition, subtraction, multiplication, and division. They are also used to represent the magnitude of a quantity, such as the number of items in a set or the time elapsed in seconds.

In computer programming, integers are often stored as binary numbers, which are sequences of bits that represent positive or negative whole numbers. Different computer architectures have different numbers of bits for representing integers, with common sizes being 8, 16, 32, and 64 bits.

The number (10)10. (11)11. (13)13 is equal to 11 × 13 × 10 = 1730 in decimal.

A divisor of a number can be represented as (4n + 1) where n is a non-negative integer.

To find the number of divisors of 1730 of the form 4n + 1, we need to find the number of factors of 1730 that can be expressed as 4n + 1.

First, we find the prime factorization of 1730:

1730 = 2 × 3 × 5 × 29

Since 1730 is an odd number, one of its divisors must also be an odd number.

The only possible values for n are 0, 1, 2, ..., (number of odd divisors - 1).

In this case, the number of odd divisors of 1730 can be calculated as:

(number of ways to choose 0 odd factors) × (number of ways to choose 1 odd factor) × (number of ways to choose 2 odd factors) × ... × (number of ways to choose 4 odd factors)

= 1 × 4 × 5 × 1 = 20

Thus, the number of divisors of 1730 of the form 4n + 1 is 20.

By applying normal approximation to the binomial concept, it can be concluded that the indicated probability is 0.62134

Normal approximation to the binomial is a method of approximating the probabilities associated with the binomial distribution using the normal distribution.

μ = n.p

σ = √np(1-p)

where μ is the mean, n is the number of trials, p is the success probability and σ is the standard deviation.

Now we have:

x = 6

n = 18

p = 0.3

Thus we can calculate the mean:

μ = np

  = 18 * 0.3

  = 5.4

Now we calculate the standard deviation

σ = √μ (1-p)

  = √ 5.4 (1 - 0.3)

  = √ 5.4 * 0.7

  = √ 3.78

  = 1.944

Then we can find the z-score using the mean and standard deviation found in the previous step:

z-score = (x – μ) / σ

            = (6 - 5.4) / 1.944

            = 0.6 / 1.944

            = 0.309

The Tangent Line to a curve at a specific point is calculated  by the derivative of the curve at that point.

The Slope of the tangent line at a point (x₀, y₀) is given by the derivative of the curve at that point, denoted as f'(x₀).

The curve x = 3t² + 5 , y = t³ - 7 ,

we have to find the value of t such that the slope of the tangent line at that point is 1/2.

we first find the derivative of y with respect to x, which is given by:

⇒ dy/dt = 3t² and dx/dt = 6t

Using chain rule to find the derivative of y with respect to x:

⇒ dy/dx = dy/dt × dt/dx = (3t²)/6t = t/2

Next, we equate derivative to 1/2 and solve for t ;

⇒ t/2 = 1/2

⇒ t = 1

So, the point where the tangent line has slope 1/2 is

⇒ (x, y) = (3t² + 5, t³ - 7)
