When merida divides her age by 3 and adds 5, the result is 9 which equation represents this situation where m is meridas age?

a/ 9= (m ~ 3) x 5
b/ m= (9 - 3 ) + 5
c/ m = (9~3) +5
d/ 9= (m~ 3) +5

The height in feet of its replica at this park, rounded to the nearest whole number is 14 feet.

Distance is the measurement of an object's horizontal distance from a specific location, whereas height is the measurement of an object's height in the vertical direction.

Since the heights of real buildings are 1:10 times higher than those of model buildings, this is evident. We also know that the actual height of the US Capitol is 289 feet, so we divide that figure by 20 to determine the model's height. That amounts to 14.45, rounding to 14. Thus, the duplicate is 14 feet, rounded up to the nearest whole number.

After a work out, the simplest form of e:g is 3:10.

Ratio is an expression which shows the relationship between two numbers or variables. It can generally be expressed in two forms, viz; a:b or a/ b.

To work out the simplest form of e:g as required in the question,

e/ f = 2/ 5

2f = 5e ........... 1

f/g = 3/ 4

3g = 4f ........... 2

From equation 1,

f = 5e/2

substitute the value of f in equation 2

3g = 4(5e/2)

3g = 10e

Therefore, e:g is given as;

3/ 10 = e/ g

3:10 = e: g

Thus in its simplest form, e:g = 3:10

In order for an expression, such as x² + 4x + , to become a perfect square trinomial, it must be in the form of a² + 2ab + b².

Perfect squares are whole numbers that are the result of multiplying a given number by itself. For example, 4 is a perfect square because it is the result of multiplying 2 by itself. Similarly, 9 is a perfect square because it is the result of multiplying 3 by itself. Other examples of perfect squares include 16 (4x4), 25 (5x5), 36 (6x6), and so on.

To do this, you must factor the expression. In this case, the expression can be factored into (x + 2)².

Once the expression has been factored into a perfect square trinomial, it can be written as (x + 2)².

This is a perfect square trinomial because it represents the area of a square, as the length of each side is equal to (x + 2).

Based on the question above, Jessica sold 260 books and Josh sold 20 books.

Let x be the number of books Josh sold

We know that:

Jessica sold 13x books

Together they sold 280 books

So we can set up an equation:

x + 13x = 280

14x = 280

x = 20

Josh sold 20 books

Jessica sold 13 * 20 = 260 books

Therefore Jessica  = 260 books sold and Josh = 20 books sold.

Step-by-step explanation:

28 = 4/5x-8

A positive second derivative means that the solution curve is concave up. Therefore, all solution curves for the given differential equation in Quadrant II are concave up.

(b) To find the second derivative of y with respect to x, we can use the chain rule. Since y is a function of x, we have [tex]dy/dx = f(x) and d^2y/dx^2 = d/dx(dy/dx) = d/dx(f(x)) = f'(x).[/tex]

To find f'(x), we can use the product rule and the given differential equation:

[tex]f'(x) = d/dx(xy^4) = y^4 + xy^4dy/dx = y^4 + xy^4f(x)[/tex]

Now, to determine the concavity of the solution curves, we need to find the sign of f'(x).

In Quadrant II, x and y are both positive, so [tex]x*y^4[/tex] is positive. Therefore, f'(x) is positive as well.

A positive second derivative means that the solution curve is concave up. Therefore, all solution curves for the given differential equation in Quadrant II are concave up.

(c) To find a particular solution to the differential equation with the given initial condition, we can use separation of variables.

The equation can be rewritten as [tex]dy/y^4 = x dx[/tex]

Integrating both sides gives:

[tex]\int\limits^ {} \,dy/y^4 = \int\limits^ {} \, dx* dx\\-1/y^3 = (x^2)/2 + C\\y^3 = -1/(x^2/2 + C)\\y = (-1/(x^2/2 + C))^(1/3)[/tex]

Using the initial condition f(4) = -1, we can find the value of C:

[tex](-1) = (-1/(4^2/2 + C))^(1/3)\\(-1)^3 = -1/(4^2/2 + C)\\-1 = -1/(16/2 + C)\\C = 15/2[/tex]

So the particular solution is:

[tex]y = (-1/(x^2/2 + 15/2))^(1/3)[/tex]

To prove that (4x - 5)^2 - 5x(3x - 8) is positive for all values of x, we can start by expanding the expression:

(4x - 5)^2 - 5x(3x - 8) = 16x^2 - 40x + 25 - 15x^2 + 40x = -14x^2 + 80x - 25

Now, we can complete the square to find that this expression is always positive:

-14x^2 + 80x - 25 = (-14x^2 + 80x) - 25

= (-14x^2 + 80x + (80/2)^2 - (80/2)^2) - 25

= (-14x + 40)^2 - 25 - 40^2 + 40^2

= 15^2 - 25

= (15 - 5)(15 + 5)

= 10(20)

= 200

Since this expression is equal to 200, which is a positive number, we can conclude that (4x - 5)^2 - 5x(3x - 8) is positive for all values of x.

The midpoint of the x-intercepts of f(x) = (x - 4)(x + 4) is (0, 0).

The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.

A compass and straightedge setup can be used to locate the midpoint of the line segment they determine given two points of interest. By initially building a lens out of circular arcs with equal radii centered at the two endpoints and joining the cusps of the lens, one can determine the midpoint of a line segment immersed in a plane. The midpoint of the segment is then the place where the line joining the cusps intersects the segment.

A = L * W

2. We know that the total amount of fencing is 400 ft.

3. We also know that one side of the garden is a river and so it doesn't require fencing.

4. Therefore, the remaining fencing must be divided equally between the two other sides of the garden (200 ft per side).

5. We now know that the length and width of the garden are both 200 ft.

The perimeter of the triangle is 23.66 inches

According to the 30-60-90 triangle theorem, the hypotenuse is twice as long as the shorter leg. Additionally, the sides of this particular triangle have a ratio of 1:2: [tex]\sqrt{3}[/tex].

Now in the question

As shown in the diagram, if the shorter leg of the triangle at 30°, 60°, and 90° is extended in the direction of the right angle by an amount equal to itself and connected to the third point, we obtain a triangle that is congruent with the original triangle. It is clear that the combined triangle is an equilateral triangle with equal sides and angles.

The greatest leg, AB, in the picture is therefore twice as long as the shortest leg of the original triangle and equal to base BC.

Therefore according to the question

given that the shorter leg is 5 inches,

hypotenuse = 5*2 = 10 inches.

the longest leg = 5[tex]\sqrt{3}[/tex], and

The perimeter is thus 5 + 10 + 5[tex]\sqrt{3}[/tex] = 15 + 5[tex]\sqrt{3}[/tex] = 23.66 inches

There will be a total of 430 pages in the book or the length of the book in pages = 430.

Adrianne reads 275 pages

So, for converting the above in form of an equation,

Let us assume that the total pages in the book be x

Let us assume that the total number of pages she read = a

Assuming that the total remaining pages that she does not read = b

So, the total number of pages will be = total pages which she read + total remaining pages.

=> x = a+b

Now, solving the values given in the questions,
