In 11.71 years the amount will double to the principal amount

The interest charged on a loan or deposit is known as compound interest. It is the idea that we use the most frequently on a daily basis. Compound interest is calculated for an amount based on both the principal amount and Compounded interest. This is the major distinction between compound and simple interest is this.

The formula  used for

where P = Principal amount

r = Rate of interest in decimal

n = Number of compounds per year  

t = Time period  

Here from the given data,

Principal amount, p = $ 2500

Rate of interest, r = 6% = 6/100 = 0.06

Number of compounds, n = 2    [ ∵ 12/6 = 2 ]

Here we need to find the time period

Let's assume that after 'n' years the amount will be doubled i.e $ 5000

From the given problem,

Amount, A = 2500(1+0.06/2)²ⁿ        

= 2500(1+0.06/2)²ⁿ  

= 2500(1 + 0.03)²ⁿ  

= 2500 (1.03)²ⁿ    

As we assumed after 'n' years the amount is $ 5000

=>  2500 (1.03)²ⁿ   = 5000

=> (1.03)²ⁿ   = 2  

Apply to log on both sides

=> log (1.3)²ⁿ  = log 2

=> 2t log (1.3) = log 2

=> 2t = log 2/ log(1.03)

=> 2t = 0.301029996/(0.0128372247)

[ use calculator for log (1.03) and log 2]

=> 2t = 23.4497722

=> t = 11.7248861  

=> t = 11.71 ≅ 11 years

Therefore,

In 11.71 years the amount will double to the principal amount

What is linear equation?

A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.

Given linear equation is

x + 2 - 6x = -13

Combine like terms:

(x - 6x) + 2 = -13

-5x + 2 = -13

The additive inverse of 2 is -2.

Add -2 on both sides:

-5x + 2 -2 = -13 -2

-5x = -15

Divide both sides by -5:

-5x/-5 = -15/-5

x = 3

Putting x = 3 in the expression 2x + 3

2x + 3 = (2×3) + 3

The 85th percentile of a normal distribution is the score that is greater than or equal to 85% of the scores in the distribution. This means that the score at the 85th percentile is the same as the score that would be earned by the top 15% of individuals in the distribution.

To find the score at the 85th percentile, we can use the standard normal distribution table or use a calculator to find the z-score corresponding to the 85th percentile. The z-score is the number of standard deviations that a score is above or below the mean of the distribution.

Using a calculator or table, we find that the z-score corresponding to the 85th percentile is 1.04. Since the mean of the distribution is 100 and the standard deviation is 15, this means that the score at the 85th percentile is 100 + (1.04 * 15) = 120.4.

Therefore, the score of an individual who is at the 85th percentile on the Weshcler IQ test is 120.4.

A function assigns the values. The function is f(x) = (8x - 8)/(x² + 2x).

A function transfers each element's value from one set to a particular element in another set.

There is a denominator and a numerator in a rational function.

The x-values that the function approaches but never reaches are known as vertical asymptotes. We can get the vertical asymptotes by setting the denominator to zero.

Since x=-2 and x=0 are the vertical asymptotes, our function's denominator will be x(x+2) = x2+2x.

Y values that the function approaches but never reaches are known as horizontal asymptotes. The degree of the numerator must be less than the degree of the denominator since the horizontal asymptote is y=0. Our numerator will be x - 1 because the x-intercept is equal to 1.

At this time, One can assume that the function is f(x) = (x - 1)/(x2+2x).

Next, we must apply the f(2)=1 condition. If we enter x=2, f(x) ought to be equal to 1. However, we must multiply the function's right side by a constant called C.

Then, the constraint f(2)=1 must be used. F(x) should be equal to 1 if we substitute x=2. The right side of the function must be multiplied by a constant C, though.

1 = C(2 - 1)/(2²+2(2))

Solve for C.

1 = C / 8\s8 = C

Consequently, the equation will be f(x) = [8(x - 1)] / [(x2 + 2x)].

f(x) = (8x - 8) / (x² + 2x)

Thus, f(x) = (8x - 8)/(x2 + 2x) is the function.

Answer:

(y - 5) = 1/4 (x - 8)

Step-by-step explanation:

Point-slope form is written in the form:

(y - y) = m (x - x)

Where the two y's and two x's are from the points, and m is the slope. To write the equation, you'd plug your points into the equation and solve for m, the slope.

(1 - 5) = m (-8 - 8)

-4 = m (-16)

m = 4/16 = 1/4

Plug m into the point-slope form equation as well as one of your points, and you have an equation.

The expression for the area that includes an exponent is 6² + (6 × 2) + 24

Area of the entire figure is 72 square inches

The dimension of the entire figure is 9 inches by 8 inches

From the question, we are to write an expression for the area of the entire figure

Area of the entire figure = Area of green shape + Area of white shape + Area of blue shape

Area of the entire figure = 6² + (6 × 2) + 24 square inches

The expression is 6² + (6 × 2) + 24

Thus,

Evaluating

Area of the entire figure = 6² + (6 × 2) + 24

Area of the entire figure = 36 + 12 + 24

Area of the entire figure = 72 square inches

b. The dimension of the entire figure

Width of the entire figure = Length of the green square + Width of the white rectangle

Width of the entire figure = 6 inches + 2 inches

Width of the entire figure = 8 inches

Then,

Length of the entire figure = Length of the white rectangle + Width of the blue rectangle

First, we will determine the width of the blue rectangle

Using the formula,

Area = l  × w

Where l is the length

and w is the width

24 = (2 + 6) × w

24 = 8 × w

w = 24/8

w = 3 inches

Length of the entire figure = 6 inches + 3 inches

Length of the entire figure = 9 inches

Finding the nth term rule of a quadratic sequence: The nth term rule of a quadratic sequence can always be written in the form an² + bn + c.

To find this rule, we need to find a, b and c

Given data ,

Let the expression be represented as = A

Now , the value of A is

A = 3 , 8 , 15 , 24 , 35 ..

Now , taking the difference of the second term and first term , we get

d₁ = 8 - 3 = 5

d₂ = 15 - 8 = 7

d₃ = 24 - 15 = 9

So , the difference of the numbers in the sequence is odd multiples

Therefore , the sequence goes in the multiples of ( n + 2 )

Now , when n = 1

a₁ = 3

when n = 2

a₂ = 8

So , a₂ = n ( n + 2 )

substituting the value for n = 2 , we get

a₂ = 2 ( 2 + 2 )

a₂ = 2 x 4

a₂ = 8

when n = 3

a₃ = 15

substituting the value for n = 3 , we get

a₃ = 3 ( 3 + 2 )

a₃ = 3 x 5

a₃ = 15

Therefore , the nth term of the quadratic sequence will be

aₙ = n ( n + 2 )
