The equation for line j can be written as y+5=5(x+5). Line k includes the point (5,3) and is perpendicular to line j. What is the equation of line k?

Answer:

Factoring a polynomial means breaking it down into simpler parts that can be multiplied together to get the original polynomial. To factor a polynomial completely, we want to find all of its factors, including any that are in the form of a constant, a variable, or a combination of both.

Let's take a look at how to factor two of the given polynomials.

x^5 - x^3

We can factor out the greatest common factor (GCF) of x^3 to get:

x^5 - x^3 = x^3(x^2 - 1)

Now, we have a difference of squares, which we can factor using the formula:

a^2 - b^2 = (a + b)(a - b)

In this case, a = x and b = 1, so we get:

x^5 - x^3 = x^3(x + 1)(x - 1)

Therefore, the polynomial x^5 - x^3 can be completely factored as x^3(x + 1)(x - 1).

3x^2 - 75

We can factor out the GCF of 3 to get:

3x^2 - 75 = 3(x^2 - 25)

Now, we have a difference of squares, which we can factor as:

a^2 - b^2 = (a + b)(a - b)

In this case, a = x and b = 5, so we get:

3x^2 - 75 = 3(x + 5)(x - 5)

Therefore, the polynomial 3x^2 - 75 can be completely factored as 3(x + 5)(x - 5).

In general, to factor a polynomial completely, we should first look for any common factors that can be factored out using the GCF. Then, we can look for special patterns, such as differences of squares, sums or differences of cubes, or quadratic trinomials that can be factored using the quadratic formula or by factoring the sum or difference of two perfect squares. Finally, we can use trial and error or other methods to find any remaining factors that are not immediately obvious.

The value of phone B is [tex]\omega = 840[/tex].

Any equation with a maximum degree of 1 is said to be linear. In a linear equation, no variable has an exponent bigger than 1, thus. There is always a straight line on the graph of a linear equation.

Given that each term in a linear equation has an exponent of 1, graphing an algebraic equation always yields a straight line.  For this reason, it is referred to as a "linear equation." There are both one-variable and two-variable linear equations.

Therefore , the solution of the given problem of inequality comes out to be Paul can drive at most 208 more miles before he will have to refill the tank.

A connection or collection of variables without the equal sign is a mathematical inequality. Equilibrium is typically followed by equity. Inequality happens when two values are not equal. Differences exist between equality and inequality. It was decided to utilize the most factors symbol because the quantities are not identical or equivalent (). Any discrepancy, regardless of how small or large, can be used to compare values.

Here,

Let x be the number of miles Paul can drive before he will have to refill the tank.

Since Paul's car can go at most 375 miles on one tank of gas, and he has already driven 167 miles, we can write the inequality:

x ≤ 375 - 167

Simplifying, we get:

x ≤ 208

Therefore, Paul can drive at most 208 more miles before he will have to refill the tank.

Interpretation: If Paul drives more than 208 miles, he will not have enough gas to complete the journey and will need to refill the tank.

Solving the equation explicitly for y and differentiating we get y' = -1/(x - 1)²

Differerentiation is the process of finding the derivative of a function.

Since we have the equation 1/x + 1/y = 1, to solve explicitly for y, we make y subject of the formula.

So, 1/x + 1/y = 1

1/y = 1 - 1/x

y = 1/(1 - 1/x)

To find y', we differentiate y with respect to x.

So, y' = dy/dx

= d[1/(1 - 1/x)]/dx

Let u = 1 - 1/x  

So,y' = d(1/u)/dx

= d(1/u)/du × du/dx

Now,

So, substituting these into dy/dx, we have that

y' = = d(1/u)/du × du/dx

= -1/u² × 1/x²

= -1/(ux)²

= -1/[(1 - 1/x)x]²

= -1/(x - 1)²

It is not possible to get 8 aces from a standard 52 cards deck. The indicated degree of likelihood as a probability value is 0 (Zero).

The procedure for probability states that the possibility of an occurrence occurring, or P(E), equals the proportion of the number of favorable outcomes to the number of total outcomes.

Mathematically,

Possibility (E) = favorable outcomes/total outcomes.

We know that there are four aces in total in a 52-card deck.

Therefore the probability of getting 8 aces can be expressed by using the factorial of the number. This can result in a decrease of numbers by multiplying the previous number, this is called the factorial of a number.

P(8A) = 7/52 × 6/51 × 5/50 × 4/49 × 3/48 × 2/47 × 1/46 × 0/45

Step-by-step explanation:

To find (c circle d)(x), we need to first find d(c(x)) and then simplify.

First, we need to find c(x) and substitute it into d(x), as follows:

d(c(x)) = d(4x - 2) = (4x - 2)^2 + 5(4x - 2)

Expanding the square and simplifying, we get:

d(c(x)) = 16x^2 - 24x + 9

Now, we have (c circle d)(x) = d(c(x)) = 16x^2 - 24x + 9.

In mathematics, the term "orthogonal" refers to a relationship between two objects where they are perpendicular or at right angles to each other.

More generally, it refers to a relationship where two objects are independent or uncorrelated with each other. For example, in Euclidean geometry, two lines are orthogonal if they meet at a right angle. In linear algebra, two vectors are said to be orthogonal if their dot product (also known as inner product) is zero. Similarly, in statistics, two variables are said to be orthogonal if they have a correlation coefficient of zero, indicating that they are uncorrelated.

Answer:

  65 cm

Step-by-step explanation:

You want the perimeter of the shape that results from removing a 60° sector from a circle.

The curved edge of the shape is 5/6 of the circumference of the circle.

  5/6C = 5/6(2πr) = 5/6·2·π·(9 cm) = 15π cm ≈ 47 cm

Each straight edge of the shape has a length equal to the radius. Then the straight edges have a total length of ...

  2r = 2(9 cm) = 18 cm

The perimeter of the shape is the sum of the length of its curved edge and the lengths of the straight edges:

  P = 47 cm + 18 cm = 65 cm

The perimeter is about 65 cm.

A total circle is 360°, so 1/6 of the circle is 60°. The size of a sector of a circle can be described by the angle measure of its central angle. Here, that means the removed portion is a 60° sector.

the parabola has an equation of y = (-1/8)x² + (1/2)x - 1/2, its vertex is at (2, 0), and it opens to the left with a focus at (0, -2) and a directrix at x=2.

Since the directrix of the parabola is a vertical line x=2, the axis of the parabola is horizontal, and its vertex is the point of intersection between the axis and the directrix, which is (2, 0). The focus is located at (0, -2), which is two units below the vertex, so the distance between the focus and the vertex is |p| = 2, where p is the distance between the vertex and the directrix. Since the directrix is to the right of the vertex, the parabola opens to the left. Therefore, its equation can be written in the form:

(x - h)² = -4p(y - k)

where (h, k) is the vertex. Plugging in the values we have, we get:

(x - 2)² = -8(y - 0)

Simplifying, we get:

x² - 4x + 4 = -8y or

y = (-1/8)x² + (1/2)x - 1/2

Therefore, the parabola has an equation of y = (-1/8)x² + (1/2)x - 1/2, its vertex is at (2, 0), and it opens to the left with a focus at (0, -2) and a directrix at x=2.

Moore's law is an observation made by Gordon Moore, co-founder of Intel Corporation, in 1965. It states that the number of transistors on a microchip doubles approximately every two years, while the cost of the chip is halved. Essentially, this means that computing power increases exponentially over time.

Moore's law is associated with exponential functions because it describes a situation in which a quantity (the number of transistors) grows at a rate proportional to its size, resulting in exponential growth. Exponential functions are often used to model phenomena in science, engineering, and other fields that exhibit this kind of behavior. In the case of Moore's law, the rate of growth is approximately 41% per year, or a doubling every 1.5 to 2 years. The formula for exponential growth is:

Where:

Moore's law can be expressed using this formula as:

Where:

For example, if a microchip had 1,000 transistors in 2000, according to Moore's law it would have 2,000 in 2002, 4,000 in 2004, 8,000 in 2006, and so on. The exponential function describes the growth of the number of transistors over time, and the formula allows us to predict future values based on past observations.
