Answer:

(5, -2).

Step-by-step explanation:

The point L' will have the same y-coordinate as L, but the x-coordinate will be opposite in sign. Since L is located at (-5,-2), L' will be located at (5,-2). So the ordered pair that describes the location of L' is (5, -2).

The first derivative of y with respect to x is d(y)/dx = 4t² + 10t, and the second derivative of y with respect to x is d(2y)/dx² = 8t + 10.

Differential equations are mathematical equations that describe how a function changes over time or with respect to its inputs.

Let x = t² + 3 and y = t² + 5t. We want to find the derivatives of y with respect to x, which means we need to use the chain rule.

The chain rule states that if y = f(u) and u = g(x), then the derivative of y with respect to x is given by

=> d(y)/dx = d(y)/du * du/dx.

First, we will find the derivative of y with respect to t, which is given by

=> d(y)/dt = 2t + 5.

Next, we will find the derivative of x with respect to t, which is given by

=> d(x)/dt = 2t.

Finally, we will multiply these two derivatives to find the derivative of y with respect to x, which is given by

=> d(y)/dx = (2t + 5)(2t) = 4t² + 10t.

Next, we will find the second derivative of y with respect to x, which is given by

=> d(2y)/dx² = d((4t² + 10t))/dt = 8t + 10.

The expression, which expresses the value of v in terms of x is:

V = x * $2,750 + $825,000

Let's call the value of each acre of property v_a = $2,750.

Then the total value of the real estate firm can be expressed as:

V = x * v_a + other assets

Where x is the number of acres of property owned.

Now, plugging in the given value for other assets,

we will get it as:

V = x * $2,750 + $825,000

So the value of the real estate firm,

V, is a function of the number of acres of property owned, x, and is equal to the product of the number of acres and the value per acre plus the value of the other assets.

Looking at the asymptotes  graph, it crosses the y-axis at y = h(x) = -1

Thus, the y-intercept is -1. The graph also crossed x-axis at..

How do you find the asymptotes on a graph?

Set the denominator to 0 and solve for x to discover the vertical asymptotes. Given that this has already been factored, solve by setting each component to zero. They are expressed as equations of lines because the asymptotes are lines.

Consequently, -1 is the y-intercept. The graph also veers off the x-axis here.

Consequently, -1 is the y-intercept. The graph also veers off the x-axis here.

As soon as the denominator equals 0, the vertical asymptotes appear. Accordingly, (2x)(x-4)=0. Vertical asymptotes are thus defined as x=0 and x=4.

Given that the degrees are identical, the horizontal asymptote in this situation corresponds to the ratio of a leading coefficients. y = [(1)(1)/(2)(1)] = 1/2.

Simply changing x = 0 makes finding the y-intercept simpler. On the other hand, because x = 0 is indeed a vertical asymptote,

Answer: the answer is c

Step-by-step explanation:

Answer:

x = 12

y = -2.5

Step-by-step explanation:

2x + 4 = 28

2x = 24

x = 12

So, we know x = 12; now we put 12 back in for x and solve for y

3(12) + 4y = 26

36 + 4y = 26

4y = -10

y = -2.5

Let's check

3(12) + 4(-2.5) = 26

36 - 10 = 26

26 = 26

So, x = 12 and y = -2.5 is the correct answer.

The equation of the parabola with given vertex and focus is (y-11)² = 36(x-7).

A parabola refers to an equation of a curve, such that a point on the curve is equidistant from a fixed point, and a fixed line.

The general equation of a parabola is: y = a(x-h)² + k or x = a(y-k)² +h, where (h, k) denotes the vertex. The standard equation of a regular parabola is y² = 4ax.

Given that, Vertex (7, 11), focus (16, 11).

Let us find an equation of the parabola for vertex (h, k)=(7, 11) and focus (16, 11).

It can be observed that both focus and vertex lie on y = 11, thus the axis of symmetry is a horizontal line.

a = 16-7 = 9 as y coordinates are the same.

Since the focus lies to the left of vertex, a = 9

Use the equation (y-11)² = 4×9(x-7)

(y-11)² = 36(x-7)

Therefore, the equation of the parabola with given vertex and focus is (y-11)² = 36(x-7).

The standard equation of the parabolas with vertex (7, 11) and focus (16, 11) are:

(y - 11)² = 36(x - 7)

A parabola is an equation of a curve, such that any point on the curve is equidistant from a fixed point called the focus and a fixed line called the directrix of the parabola.

We have,

(y - k)² = 4p (x - h) open right

(y - k)² = -4p (x - h) open left

Where focus = (h - p, k)  or (h + p, k) and vertex = (h, k)

Now,

Equation of parabola (y - k)² = -4p (x - h) that open left.

(h, k) = (7, 11)

h = 7 and k = 11

(h - p, k) = ( 16, 11)

h - p = 16

7 - p = 16

7 - 16 = p

p = -9

So,

(y - 11)² = 36(x - 7)

Equation of parabola (y - k)² = 4p (x - h) that open right.

(h, k) = (7, 11)

h = 7 and k = 11

(h + p, k) = (16, 11)

h + p = 16

7 + p = 16

p = 16 - 7

p = 9

So,

(y - 11)² = 36 (x - 7)

Thus,

The standard equation of the parabolas is:

(y - 11)² = 36(x - 7)

The total amount present in the account is  $555 in 5 years with a rate of 2.2%.

Simple interest is a way to figure out how much interest will be paid on a sum of money at a specific rate and for a specific duration of time. Contrary to compound interest, where we add the interest of one year's principal to the following year's principal to compute interest, the principal amount under simple interest remains constant.

Simple interest is a quick and simple approach to figure out how much money has accrued interest. Interest is always applied to the initial principle amount and is calculated at the same rate for each period of time. Any bank where we deposit money will pay us interest on that amount. Simple interest is one of several forms of interest that banks charge.

It is given The initial Principal is $500

The interest earned is $55

The total amount present in the account is $(500 + 55) = $555 in 5 years

While plotting graphs with power to x values, it usually depends on two things. For example, lets take an equation, y = kxⁿ

As the value of coefficient of x, that is k increases the graph becomes narrower and as the value of k decreases the graph becomes wider. Here in the questions given all have the same coefficients for x, k=1.

So here the graph only depend on the power of x.

As the power increases the graph gets gets narrower. So the graph of x¹⁰ will be narrower than x⁴. As both 10 and 4 are even numbers, for all values of x, y will be positive and parabolas are formed.

In the case of x⁷,  as 7 is odd the value of y can be both positive and negative.

We learn from the question that Johnny will need to buy 11 bags.

When you don't have much room, planters are a terrific choice since they let you showcase little trees and plants everywhere there is some sunshine. And you can still accept gardening and enjoy the benefits of raising your own food even if you just have a small patio, driveway, or balcony.

We'll start by determining the planter's volume. To achieve this, we'll calculate a triangular pyramid's volume:

Volume = (Ground Area x Altitude) / 3.

The planters measures 4 square feet in base area and 8 feet in height, so:

Volume = (4 x 8) / 3

Volume = 16 cubic feet

Now we know that Johnny needs 16 cubic feet of potting soil, and each bag of soil has 1.5 cubic feet, so:

Number of Bags = Volume / Volume per Bag

Number of Bags = 16 / 1.5

Number of Bags = 10.67

Let's evaluate each equation to see if they are equivalent to "6x = 20":

6x ÷ 6 = 20 ÷ 6:

Dividing both sides of the equation by 6 gives us "x = 20/6" or "x = 10/3." This equation is not equivalent to "6x = 20."

6x ÷ 6 = 20 ÷ 20:

Dividing both sides of the equation by 6 gives us "x = 20/6" or "x = 10/3." Then, dividing both sides of the equation by 20 gives us "x = 1."

This equation is equivalent to "6x = 20" since both sides simplify to the same value.

6x + 5 = 20 + 5:

Adding 5 to both sides of the equation gives us "6x + 5 = 25." This equation is not equivalent to "6x = 20."

6x − 1 = 20 − 1:

Subtracting 1 from both sides of the equation gives us "6x − 1 = 19."

This equation is not equivalent to "6x = 20."

6x × 6 = 20 × 20:
