Using Simple interest, savings account for her needed to deposit $1,842.82 each year.

A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest. Now, before exploring the idea of basic curiosity in further detail,

t can also be computed using the annuity factor of 5% for 17 years to divide the total sum of $50,000.

The 529 plan, according to available data, is a tax-advantaged or tax-qualified savings plan designed to encourage individuals to save for future education costs of their relations or for themselves.

Data and Calculations:

N (number of intervals) = 17 years

Interest every year is equal to 5%.

Present Value = $0 PV

FV (Future Value) = $50,000 ($31,327.88 + $18,672.12)

Results: PMT = $1,842.82

Sum of all periodic payments = $31,327.88 ($1,842.82 x 17)

Total Interest = $18,672.12

Hence, in order to save $50,000 in 17 years at a 5% return for his granddaughter, the man who wanted to open a 529 college savings account for her needed to deposit $1,842.82 each year.

Hence the interest the bank will collect will be $117.53.

Answer:

Side PQ is the same as RQ

Angle QRS is the same as QPS

Step-by-step explanation:

For the given rectangle, the ordered pair that represents the location of point Z is (11,6).

What is a rectangle?

The internal angles of a rectangle, which has four sides, are all precisely 90 degrees. The two sides come together at a straight angle at each corner or vertex. The rectangle differs from a square because its two opposite sides are of equal length. Also, it is known as an equiangular quadrilateral. Rectangles can also be referred to as parallelograms because their opposite sides are equal and parallel. A rectangle's diagonals cut each other in half. It has four right angles and is a parallelogram. The complete distance that the rectangle's outside boundary covers is referred to as its perimeter. The area a two-dimensional form occupies in a plane is known as its area. It has a square unit of measurement. As a result, the rectangle's area is the space enclosed by its exterior lines. It is the same as the length times the width calculation.

The rectangle should have opposite sides of equal length.

Here,

XY = WZ

XW = YZ

From the graph, we can write the coordinates as:

X = (7,11)

Y = (11,11)

W = (7,6)

Point Z should lie directly below Y so that it is in a straight vertical line.

Then it should have the same x coordinate as Y.

It should also lie in the same horizontal line that passes through W.

So it will have the same y coordinate as W.

Therefore for the given rectangle, the ordered pair that represents the location of point Z is (11,6).

The solution of the inequality is x > -4. In the interval notation is (-4,∞).

What is inequality?

In mathematics, inequalities specify the relationship between two non-equal values. Equal does not imply inequality. Typically, we use the "not equal symbol (≠)" to indicate that two values are not equal. But various inequalities are used to compare the values, whether it is less than or greater than.

An inequality exists when two real numbers or algebraic expressions are connected by the symbols “>”, “<”, “≥”, “≤”.

The given inequality is:

6x + 8 > - 16

Subtract 8 from both sides:

6x + 8 - 8 > - 16 - 8

Using the method of undetermined coefficients, the particular solution is:

[tex]\mathrm{y_p(t) = 6e^{2t} \times cos(9t) + 3^{2t} \times sin(9t)}[/tex]

To use the method of undetermined coefficients, we assume that the particular solution has the same form as the forcing term, but with undetermined coefficients.

Let's start by finding a particular solution for the equation:

y′′ − 4y′ + 81y = 48[tex]e^{2t}[/tex]cos(9t) + 80[tex]e^{2t}[/tex]sin(9t) + 3[tex]e^{(-t)[/tex]

Since the forcing term contains both exponential and trigonometric functions, we'll assume that the particular solution is of the form:

[tex]y_p[/tex](t) = A*[tex]e^{2t}[/tex]cos(9t) + B[tex]e^{2t}[/tex]*sin(9t) + C[tex]e^{(-t)[/tex]

where A, B, and C are undetermined coefficients that we need to determine.

Let's find the first and second derivatives of [tex]y_p[/tex](t):

[tex]y'_p[/tex](t) = (2A + 9B)*[tex]e^{2t}[/tex]*sin(9t) + (2B - 9A)*[tex]e^{2t}[/tex]*cos(9t) - C[tex]e^{(-t)[/tex]

[tex]y''_p[/tex](t) = (4A - 81B)*[tex]e^{2t}[/tex]*cos(9t) + (4B + 81A)*[tex]e^{2t}[/tex]*sin(9t) + C[tex]e^{(-t)[/tex])

Substituting these expressions into the differential equation, we get:

(4A - 81B)*[tex]e^{2t}[/tex]*cos(9t) + (4B + 81A)*[tex]e^{2t}[/tex]*sin(9t) + C[tex]e^{(-t)[/tex]

4[(2A + 9B)*[tex]e^{2t}[/tex]*sin(9t) + (2B - 9A)*[tex]e^{2t}[/tex]*cos(9t) - C[tex]e^{(-t)[/tex]

81[A*[tex]e^{2t}[/tex]cos(9t) + B[tex]e^{2t}[/tex]*sin(9t) + C[tex]e^{(-t)[/tex]]

= 48[tex]e^{2t}[/tex]cos(9t) + 80[tex]e^{2t}[/tex]sin(9t) + 3[tex]e^{(-t)[/tex]

Simplifying and grouping terms, we get:

[(4A + 18B)cos(9t) + (18A - 4B)sin(9t)][tex]e^{2t}[/tex]+ (81C + 3)[tex]e^{(-t)[/tex] = 48[tex]e^{2t}[/tex]cos(9t) + 80[tex]e^{2t}[/tex]sin(9t) + 3[tex]e^{(-t)[/tex]

Since the two sides of the equation must be equal for all values of t, we can equate the coefficients of the exponential and trigonometric functions on both sides:

4A + 18B = 48 => A = 6

18A - 4B = 80 => B = 3

81C + 3 = 3 => C = 0

Therefore, the particular solution is:

[tex]y_p[/tex](t) = 6[tex]e^{2t}[/tex]*cos(9t) + 3[tex]e^{2t}[/tex]*sin(9t)

Thus, the general solution of the differential equation is:

[tex]\mathrm{y(t) = y_h(t) + y_p(t)}[/tex]

where [tex]y_h[/tex](t) is the complementary solution. Since the characteristic equation of the differential equation is r² - 4r + 81 = 0, it has two complex conjugate roots: r = 2 ± 9i. Therefore, the complementary solution is:

[tex]y_h[/tex](t) = [tex]c_1[/tex]*[tex]e^{2t}[/tex]cos(9t) + [tex]c_2[/tex][tex]e^{2t}[/tex]*sin(9t).

A sample space is the collection of all potential results of a random experiment or process in probability theory. It's represented by the symbol (the uppercase Greek letter omega).

For instance, if we flip a fair coin, the sample space is H, T, where H stands for the outcome of a heads result and T stands for a tails result. The sample space on a normal six-sided dice is 1, 2, 3, 4, 5, and 6.

No matter how likely they are, all outcomes are included in the sample area. In order to accurately estimate the probability of an event, the sample space must be defined.

Now,

To choose a systematic sample of size n = 10 from a town with 5000 people, we will use a systematic sampling technique. Here are the steps to follow:

Determine the sampling interval: The sampling interval is the number of people in the population divided by the desired sample size. In this case, the sampling interval is 5000/10 = 500.

Select a random starting point: To ensure the sample is representative of the population, we need to select a random starting point between 1 and 500.

We can use a random number generator to choose a starting point. Suppose we choose the number 243 as our starting point.

Select every nth person: Starting from the chosen starting point, we will select every 500th person until we reach a sample size of 10.

So, we will select people with the following index numbers: 243, 743, 1243, 1743, 2243, 2743, 3243, 3743, 4243, and 4743.

The area of the triangle is approximately 1.987 square units.

The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

Using sin rule of a triangle,

[tex]\frac{Sin A}{a} = \frac{Sin C}{c} = \frac{Sin B}{b}[/tex]

In our case,

[tex]\frac{Sin 18}{1.6} = \frac{Sin Q}{4.2} = \frac{Sin P}{QR}[/tex]

From equation 1

[tex]\frac{Sin 18}{1.6} = \frac{Sin Q}{4.2} \\\frac{(Sin 18)*4.2}{1.6} = {Sin Q}\\Sin \ Q =21/8* sin\ 18\\[/tex]

Thus,

∠Q = 125.79 degrees

since sum of all angles is 180 degrees

so,

∠P = 180-125.79-18

∠P = 36.21

So From the equation 1

[tex]\frac{Sin 18}{1.6} = \frac{Sin P}{QR}\\\frac{Sin 18}{1.6} = \frac{Sin 36.2}{QR}\\QR = \frac{Sin 36.2}{\frac{Sin 18}{1.6}}[/tex]

QR = 3.06 cm

To find the area of the triangle, we can use Heron's formula:

Area = √(s(s-a)(s-b)(s-c))

where a, b, and c are the side lengths and s is the semi perimeter:

s = (a + b + c)/2

Plugging in the values we get:

s = (4.2 + 1.6 + 3.052)/2

s ≈ 4.426

Now we can use Heron's formula:

Area = √(4.426(4.426-4.2)(4.426-1.6)(4.426-3.052))

Using a calculator, we find:

Area ≈ 1.987 square units

What is an area?

In geometry, area is the measure of the amount of surface enclosed by a two-dimensional shape or a planar figure. It is typically measured in square units such as square centimeters, square inches, or square meters.

To find the area of a rectangle, we can multiply its length by its width.

Given width = 8 m and length = 16 m, the area of the rectangle is:

Area = length x width = 16 m x 8 m
Area = 128 cm^2 ------(I)

To find the area of a rectangle, we can multiply its length by its width.

Given width = 5 m and length = 6 m, the area of the rectangle is:

Area = length x width = 6 m x 5 m
Area = 30 m^2 -----(II)

The area of a triangle is given by the formula A = 1/2 x b x h, where A is the area, b is the base of the triangle, and h is its height.

Given that the height of the triangle is 8 m and its base is 5 m, the area of the triangle is:

A = 1/2 x b x h = 1/2 x 5 m x 8 m
Area = 20 square m  ---------(III)

Adding (I), (II) and (III), we get

Area = 128 + 30 + 20

Area = 178 sq.m

Hence, the area of the complex figure is 178 square meters.

The area of the canvas is 8 1/8 square units.

The area of a canvas with dimensions of 2 1/2 x 3 1/4 can be calculated by multiplying the length by the breadth.

2 1/2 and 3 1/4 must first be converted into improper fractions:

2 1/2 = (2 x 2 + 1) / 2 = 5/2

3 1/4 = (3 x 4 + 1) / 4 = 13/4

The area may now be calculated by multiplying the two fractions:

(5/2) x (13/4) = (5 x 13) / (2 x 4) = 65/8

The canvas's surface area is 65/8 square units as a result. This can be expressed as a mixed number as well:

What is volume ?

Volume is a physical quantity that measures the amount of three-dimensional space that a substance or object occupies. It is usually measured in cubic units, such as cubic meters, cubic centimeters, cubic feet, or cubic inches.

To construct the box, we start with a square piece of cardboard that is 8 inches by 8 inches. We will cut out squares from each corner with side length x inches. This will leave us with a rectangular piece of cardboard with dimensions 8-2x by 8-2x, and we can fold up the sides to form the open box.

The height of the box will be x inches, and the length and width of the base of the box will be 8-2x inches. Therefore, the volume of the box will be:

Volume = Length x Width x Height

The answer that you are looking for is 70º

Step-by-step explanation:

Usually, in three-sided figures, there is a total of 3 angles all adding up to 180º.

So in turn, since most quadrilaterals are made up of 2 triangles all the sides have to equal to 360º.

We can use the equation 360 = 110×2+q2

To find the value of q.

The First step to do is to simplify all terms with 110×2 being equal to 220 and q2 staying the same.

We then use the opposite symbol to remove 220 leaving q2 by itself while 360 is subtracted by 220 and turned into 140.

The only thing left to do is to do the opposite operation of multiplying, which is dividing and dividing both sides by 2 leaving q = 70.

You can find the equation below:
360 =  110×2+q2
360 =  220 + q2
-220 = -220 + q2
 140 = q2
  ÷2 = ÷2

According to the given composite function the correct answer is , (g o h)[tex](n/2) = 8n^2 + 42n + 35.[/tex]

What is a composite function?

A composite function is a function that is formed by combining two or more functions. It is obtained by taking the output of one function and using it as the input of another function.

Suppose we have two functions, f(x) and g(x). The composite function of f and g, denoted by f o g, is defined as:

(f o g)(x) = f(g(x))

In words, this means that we apply the function g to the input x, and then we apply the function f to the output of g. The result is a new function that combines the effects of both f and g.

For example, if we have [tex]f(x) = x^2[/tex] and g(x) = 2x + 1, then the composite function f o g is:

[tex](f o g)(x) = f(g(x)) = f(2x + 1) = (2x + 1)^2 = 4x^2 + 4x + 1[/tex]

The composite function f o g takes an input x, applies g to it to get 2x + 1, and then applies f to that to get [tex]4x^2 + 4x + 1[/tex] as the final output.

To compute (g o h)(n/2), we need to first evaluate h(n/2) and then substitute the result into g(n) in place of n.

So, first we evaluate h(n/2):

h(n/2) = 4(n/2) + 5 = 2n + 5

Now we substitute this expression into g(n):

[tex]g(h(n/2)) = 2(h(n/2))^2 + h(n/2)[/tex]

[tex]= 2(2n + 5)^2 + (2n + 5)[/tex]

[tex]= 2(4n^2 + 20n + 25) + 2n + 5[/tex]

[tex]= 8n^2 + 42n + 35[/tex]

Therefore, [tex](g o h)(n/2) = 8n^2 + 42n + 35.[/tex]

The cost of Shai's haircut is $25 and the cost of his shave is $30, so the subtotal before tax and tip is:

$25 + $30 = $55

The sales tax is 8.25%, so the tax amount is:

$55 * 0.0825 = $4.54

The total cost before tip is:

$55 + $4.54 = $59.54

If Shai tips 25% on the subtotal, the tip amount is:

$55 * 0.25 = $13.75

So the total cost including tax and tip is:

$59.54 + $13.75 = $73.29

Therefore, Shai must pay a total of $73.29 if he gets his hair cut and beard shaved and he tips the barber 25%. The answer is option (B).
