∴n²-1=4m

⇒n²=4m+1

⇒n=√(4m+1)… … … … 1

If m=12

put the value of m in 1 equation

n=√(4×12+1)

Answer:

(a) 512 ft² , (b) 720 ft²

Step-by-step explanation:

the area of a rectangle is calculated as

area = length × width

(a)

area of pool = 32 × 16 = 512 ft²

(b)

the area of the deck is calculated as

area of outer rectangle - area of pool

area of outer rectangle = 44 × 28 = 1232 ft²

area of deck = 1232 - 512 = 720 ft²

The height of the cylinder is approximately 42/11 inches. The answer is option C.

What is the formula for the volume of the cylinder?

The formula for the volume of a cylinder is V = πr²h, where V is the volume, r is the radius, and h is the height.

We are given that the volume of the cylinder is 1 and one-third in^3 and the radius is one-third in. Substituting these values into the formula, we get:

1 and one-third = 4/3

V = π(1/3)²h = 4/3

Simplifying the equation, we get:

h = (4/3) / (π(1/3)²) = (4/3) / (π/9) = (4/3) * (9/π) = 12/π

Approximating π as 22/7, we get:

h ≈ (12/π) ≈ (12/(22/7)) = 42/11 inches

Therefore, the height of the cylinder is approximately 42/11 inches. The answer is option C.

The surface area of the shape which was formed when four identical cubes were joined, is 882 yd ².

The surface area of a cube can be found by the formula :

= Number of faces x Length of a side ²

When four identical cubes were joined, this leads to the creation of 18 faces which means that the surface area of the cube would then be :

= 18 x 7 x 7

= 18 x 49

Answer:

Therefore, Roberto will pay a total of $593,654 for his $340,000 house, including $253,654 in interest over the 30-year period.

Step-by-step explanation:

Roberto paid 20% down on a $340,000 house, which is 0.20 x $340,000 = $68,000.

So, the amount he financed is $340,000 - $68,000 = $272,000.

Roberto financed the $272,000 at 5% interest for 30 years, making monthly payments of $1460.15.

To find the total amount he will pay for the house, we need to calculate the total amount he will pay over the 30-year period.

First, we can calculate the total number of payments he will make over the 30 years by multiplying the number of years by the number of payments per year:

30 years x 12 months/year = 360 payments

The total amount Roberto will pay is the sum of all the monthly payments he makes over the 30 years:

Total amount = 360 x $1460.15 = $525,654

However, this includes both the principal amount of $272,000 and the interest he will pay over the 30 years. To find out how much he will pay in interest, we can subtract the principal from the total amount:

Total interest = $525,654 - $272,000 = $253,654

Therefore, Roberto will pay a total of $593,654 for his $340,000 house, including $253,654 in interest over the 30-year period.

To make a regular polygon with 96 sides we can take a circle as a starting point and divide it into 96 equal sides.

To create a regular polygon with 96 sides, we must take into account that all its sides must be equal, so we can take a circumference as a starting point. In this case, the circumference has 360°, so we must divide this into 96 parts and the result would be the distance between the edges of the polygon.

In this case, we must make a circle with a protractor and mark every 3.75°, when we have completed this procedure in the entire circumference we will have a regular polygon with 96 sides.

The figures to complete the table, based on the pattern, would be 6. 20, 7.00.

To complete the table, you need to find the common difference between the values in B which is :

= 0. 80                                                   = 0. 80

The next two values would therefore be :

Answer:

the charge for opening up the account was $155.

Step-by-step explanation:

To find the charge for opening up the account, we need to subtract the interest from the total amount borrowed.

The total amount repaid at the end of the loan period is the sum of the amount borrowed and the interest charged. In this case, the total amount repaid is:

$2,500 + $155 = $2,655

The interest charged on the loan is the difference between the total amount repaid and the amount borrowed. Therefore, the amount charged for opening up the account is:

$2,655 - $2,500 = $155

So the charge for opening up the account was $155.

Answer:

      5x^2 - 19x + 15

Step-by-step explanation:

We must multiply the pool's length and width to determine its area. We can factor the equation f(x)=(x-3)(5x+2) to determine the length and width:

f(x) = (x-3)(5x+2)

f(x) = 5x^2 - 13x - 6

One of the parameters is the pool's length (x-3), while the other is its breadth (5x+2). We multiply these two elements to determine the area:

Area is length times width (x-3)

(5x+2)

By extending this statement using FOIL (First, Outer, Inner, Last), we may make it simpler:

Area is equal to  5x^2 - 13x - 6x + 15

Area: 5x^2 - 19x + 15

The pool at Philip and Laura's home is therefore  5x^2 - 19x + 15 square feet in size. We are unable to establish the precise square footage of the pool because we were not given a specific figure for x.

The inequality expression g - 17 ≥ 17 when solved has a solution of g ≥ 34

Given the inequality expression

g - 17 ≥ 17

To solve the inequality g - 17 ≥ 17, we need to isolate the variable g on one side of the inequality.

We can do this by adding 17 to both sides of the inequality:

g - 17 + 17 ≥ 17 + 17

Simplifying, we get:

g ≥ 34

So the solution to the inequality is all values of g that are greater than or equal to 34.

We can graph this solution on a number line by placing a closed circle at 34 and shading to the right, to indicate that any value greater than or equal to 34 satisfies the inequality.

What are the two numbers if their sum is −7 and their difference is 14?

The sides of the dilated triangle are parallel to the sides of the original triangle, but their lengths are multiplied by the scale factor k.

A triangle is a closed two-dimensional figure with three straight sides and three angles. It is one of the basic shapes in geometry and is used in many different areas of mathematics, science, and everyday life. A triangle is defined by its three vertices (or corners), which are the points where the sides of the triangle intersect. The three sides of the triangle are the line segments connecting the vertices. The three angles of the triangle are the angles formed by the intersection of two sides.

Here,

To dilate a triangle with a center at the origin, we need to multiply the coordinates of each vertex by the scale factor k. However, in this case, the center of dilation is not at the origin, but at the point Irgun. To perform the dilation, we can follow these steps:

Plot the original triangle with vertices (2,0), (4,-4), and (6,2).

Draw a line segment from the center of dilation Irgun to each vertex of the triangle.

Measure the distance from Irgun to each vertex, and multiply it by the scale factor k = 1.5 to find the new distance.

Use the new distances to construct the dilated triangle by drawing line segments from Irgun to points that are 1.5 times farther away from Irgun than the corresponding vertices of the original triangle.

The resulting dilation of the triangle with center at Irgun and scale factor k = 1.5 is shown below:

In this image, the original triangle is shown in black, and the dilated triangle is shown in blue. The center of dilation Irgun is marked with a red dot. Note that the new vertices of the dilated triangle are (0.5,0), (3,-6), and (7.5,3), which are 1.5 times farther away from Irgun than the corresponding vertices of the original triangle.

What is Linear equation ?

A linear equation is an algebraic equation in which each term is either a constant or a product of a constant and a variable raised to the first power, also called a linear term.

A linear equation can be written in the form of:

y = mx + b

where y is the dependent variable, x is the independent variable, m is the slope or gradient of the line, and b is the y-intercept (the point where the line crosses the y-axis).

The equations that are true for x = -2 and x = 2 are:

[tex]x^{2}[/tex] - 4 = 0, which is true for x = -2 but not for x = 2

4[tex]x^{2}[/tex] = 16, which is true for x = 2 but not for x = -2

Is sin (θ) = - 2/ 3, the options that are possible include:

Since sec(θ) is negative, cos(θ) is also negative (sec(θ) = 1/cos(θ)). This means θ is in the second or third quadrant, but since sin(θ) is negative, θ must be in the third quadrant. Now let's check if the given tan(θ) value is correct:

tan(θ) = sin(θ)/cos(θ)

Since we already know that cos(θ) is negative, we have cos(θ) = -(√5)/3.

Now calculate tan(θ):

tan(θ) = (-2/3) / (-(√5)/3) = 2/√5
