The present p value which have to be invest in future is $7619.05 at simple interest rate r.

Simple Interest:

Simple interest (S.I) is a method of calculating the amount of interest on a specific amount of money.

The simple interest formula helps determine the amount of interest given a principal, interest rate, and term.

The formula for simple interest is:

SI = PTR/100

where SI = simple interest

P = principal

R = interest rate (percentage)

T = term (years)

For calculating total amount

             Amount (A) = principal Book (P) + Interest (I)

where

Amount (A) is the total amount repaid at the end of the borrowed period.

The simple interest total amount formula can also be written as:

                                    A = P(1 + RT)

where

A = Total amount after specified period

P = Principal or original loan amount

R = Interest rate (annual)

T = Time (annual )

According to the Question:

Simple interest: I = PTR            ---------------------------- (1)

Future amount : A = p + I = p + PTR         ------------------ (2)

Given that:

r = 10% = 0.1

t = 6 months = 0.5 year

A = future amount = 8000

Now,

8000 = p + p (. 1)(0.5)

⇒ 8000 = 1.05 p

⇒ p = 8000/1.05

⇒ p = $ 7,619.05

Now,

Putting the value of p in equation (2)

I = 7619.05 (0.1) (0.5 ) = 380.95

7619.05 + 380.90 = $8,000

Here, we'll utilize that fundamental transformation to recast z = a + bi in a different (sometimes more practical) form that is based on the polar transformation. The trigonometric form of a complex number is the name of this new representation.

Given

8 + 3i

Required

Rewrite in trigonometric form.

The trigonometric form of a complex equation is

z = r[cosθ + isinθ]

Let a = 3 and b = 8

Where

r is calculated by

r² = b² + a²

And

θ is calculated by

θ = arctan(a/b)

Substituting 3 for a and 8 for b

r² = a² + b² becomes

r² = 3² + 8²

r² = 9 + 64

r² = 73

√r² = √73

r = √73

r = 8.544

Calculating θ

θ = arctan(a/b) becomes

θ = arctan(3/8)

θ = arctan(0.375)

θ = 20.556°

θ = 20.6 --- Approximated

The required answer is the fourth root of 625 is 5. In summary, the fourth root of 625 is 5.

To find the fourth root of 625, we need to determine the number that, when raised to the power of 4, equals 625. Here's the step-by-step process:

Step 1: Start with the number 625.

Step 2: Take the fourth root of 625.

Since we're looking for the fourth root, we need to find a number that, when raised to the power of 4, equals 625.

Step 3: Determine the number that, when raised to the power of 4, equals 625.

To find this number, we can use the concept of exponentiation. Let's denote the unknown number as "x". Mathematically, we have [tex]x^4 = 625[/tex]..

Step 4: Solve the equation [tex]x^4 = 625[/tex].

To solve this equation, we need to find the value of x. Taking the fourth root of both sides of the equation, we have [tex]\sqrt[4]{(x^4)} =\sqrt[4] {625}.[/tex]

The fourth root of 625 is (625)^(1/4).

Step 5: Simplify the expression.

Answer: To calculate the length of a loan, you need to know the total cost of the loan, the monthly payment amount, and the interest rate. In this case, the total cost of the car is $16,000, the monthly payment amount is $250, and the interest rate is 7.3%.

First, you need to calculate the total interest that will be paid on the loan. This can be done by multiplying the total cost of the loan by the interest rate, and then dividing by 100 to convert the result to a percentage. In this case, the total interest paid would be $16,000 * 7.3 / 100 = $1,168.

Next, you need to subtract the total interest from the total cost of the loan to find the total amount of the loan that will be used to pay for the car. In this case, the total amount of the loan used to pay for the car would be $16,000 - $1,168 = $14,832.

Finally, you can use this total amount and the monthly payment amount to calculate the length of the loan by dividing the total amount by the monthly payment amount. In this case, the length of the loan would be $14,832 / $250 = 59.32 months, or just over four years. The answer is 59.32 months.

The homeowner should go with option 1 for his budget of $40,200 to use complete budget.

Any equation that can be rearranged in the standard form as is referred to as a quadratic equation (from the Latin quadratus, "square").

ax² + bx + c = 0

where x is a value that is unknown, a, b, and c are numbers that are known, and a is a negative number. The numbers a, b, and c are the equation's coefficients; they are referred to as the constant or free term, the quadratic coefficient, and the linear coefficient, respectively.

Solutions of the equation and roots or zeros of the expression on its left-hand side are the values of x that satisfy the equation. There can only be two solutions to a quadratic equation. One suggests that there is only one solution, which is a double root.

Given a rectangular pool of  35-foot by 20-foot

area of pool = 35 x 20 = 700 sq. foot

and to built a patio around pool of equal width,

budget of patio of $40,200 all amount to be used,

Option 1: Surround the pool with a concrete band of equal width on all sides. The concrete costs $50 per square foot.

the area covered by amount is 40200/50 = 804

let width of patio be x

new length = 35 + x and new breadth = 20 + x

area covered by patio = new area including width - area of pool

new area including width = area covered by patio +  area of pool

new area including width = 804 + 700 = 1504

1504 =  (35 + x)(20 + x )

1504 = x² + 35x + 20x + 700

x² + 55x - 804 = 0

solving the equation by quadratic formula

x = (-b ± [tex]\sqrt{b^{2} - 4ac }[/tex])/ 2a

where a = 1, b = 55, and c = -804

x = (-55 ± [tex]\sqrt{(55)^{2} - 4*1*(-804) }[/tex])/2

x = (-55 ± √(3025 + 3216))/2

x = (-55 ± 79)/2

taking positive values

x = (-55 + 79)/2 = 12

new length = 35 + 12 = 47 foot

new breadth = 20 + 12 = 32 foot

area covered by patio = (47x32) - (35x20)

area covered by patio = 804 sq. foot

and cost will be 804 x 50 = $40,200

for option 2:  Surround the pool with a tile band of equal width on all sides. The tile costs $80 for each square foot tile.

area for patio = 40200/80 = 502.5

since the area is in fraction the cost will come in approximation.

This is so because a fair coin has 2 sides.

So, we have:

n = 1024

There is only one occurrence of having 10 tails in a row in the 1024 possible outcomes.
