It would take approximately 11.6 years for the account balance to reach $20,000 if compounded annually.
What is the difference between compound interest and simple interest?The costs a borrower pays a lender for a loan are known as interest. For instance, banks charge interest on the loans that consumers take out.
Simple interest is the term used to describe interest that is based on the principle amount that a person borrows or invests. Contrarily, compound interest is computed on the principle borrowed or invested by the individual as well as the accrued interest from the prior period.
The formula for compound interest is:
A = P(1 + r/n)ⁿˣ
where, A is the amount
P is the principal amount = $10,000
r is the rate = 6% = 0.06
x is time.
n = 1
Substituting the values,
$20,000 = $10,000(1 + 0.06/1)¹ˣ
2 = (1.06)ˣ
Taking the natural logarithm of both sides:
ln(2) = t * ln(1.06)
t = ln(2) / ln(1.06) ≈ 11.6
Therefore, it would take approximately 11.6 years for the account balance to reach $20,000.

Solve the equation by factoring y= x^2-8x+16=7
The solution of the equation by factoring is x = 6.645 and x = 1.355.
What is factoring?The breaking or breakdown of an entity (such as a number, a matrix, or a polynomial) into a product of another entity, or factors, whose multiplication results in the original number, matrix, etc., is known as factorization or factoring in mathematics. An algebraic expression is factorised when it is written as the product of its factors. Certain variables, factors, or algebraic expressions might be present.
The given equation is:
x² - 8x + 16 = 7
x² - 8x + 16 - 7 = 0
x² - 8x + 9 = 0
Using the quadratic formula we have:
x = 8 ±√(8)² - 4(1)(9) /2(1)
x = 8 ± 5.29/2
x = 8 + 5.29/2 and x = 8 - 5.29/2
x = 6.645 and x = 1.355
Hence, the solution of the equation by factoring is x = 6.645 and x = 1.355.

Determine if it is Exponential growth.
Use the information below to plug in the numbers to the formula. f(x)=a(1+or-r)^x
The value of x for each value of f(x) will lie between two consecutive whole numbers. List the whole numbers.
initial value: 1,000
decay rate: 20%
f(x) = 500
The value of x that corresponds to f(x) = 500 lies between 0 and 1. The whole numbers between 0 and 1 are 0 and 1, so the answer whole numbers are 0 and 1.
Describe Exponential Growth?Exponential growth is a mathematical concept that describes a process where a quantity grows at an increasing rate proportional to its current value. In other words, the larger the quantity, the faster it grows. This leads to a graph that is characterized by a rapid upward curve that becomes steeper and steeper over time.
Exponential growth is often represented by the equation y = abˣ, where y is the final amount, a is the initial amount, b is the growth factor or base, and x is the time or number of periods.
The function f(x) = a(1 - r)ˣ represents exponential decay, where "a" is the initial value, "r" is the decay rate as a decimal, and "x" is the time variable.
In this case, the initial value is 1,000, and the decay rate is 20%, or 0.20 as a decimal. Therefore, the equation for the function becomes:
f(x) = 1,000(1 - 0.20)ˣ = 800ˣ
To find the whole numbers that correspond to a value of f(x) = 500, we can set the equation equal to 500 and solve for x:
500 = 800ˣ
Taking the natural logarithm of both sides, we have:
ln(500) = ln(800ˣ)
Using the property of logarithms, we can bring down the exponent:
ln(500) = x ln(800)
Solving for x, we divide both sides by ln(800):
x = ln(500) / ln(800) ≈ 0.717
Therefore, the value of x that corresponds to f(x) = 500 lies between 0 and 1. The whole numbers between 0 and 1 are 0 and 1, so the answer is:
The whole numbers are 0 and 1.

given: trapezoid abcd where ba is congruent to cd angle abc is congruent to angle dcb
prove bd is congruent to ac
By the hypotenuse-leg congruence theorem (HL theorem), triangles ABD and CBD are congruent.
What is Trapezoid ?
A trapezoid is a four-sided polygon with at least one pair of parallel sides. It is also known as a trapezium in some countries.
To prove that BD is congruent to AC, we will use the fact that the opposite sides of a trapezoid are parallel.
Since AB and CD are parallel, and BC is a transversal, we know that angles ABC and DCB are supplementary (they add up to 180 degrees).
From the given information, we know that angle ABC is congruent to angle DCB. Therefore, both angles must be equal to 90 degrees (since their sum is 180 degrees).
Now consider the right triangles ABD and CBD.
In triangle ABD, we have a right angle at angle ABD, and we know that AB is congruent to CD (given).
In triangle CBD, we have a right angle at angle BCD, and we know that BC is congruent to BC (reflexive property).
We also know that angle ABD is congruent to angle BCD (since they are both equal to 90 degrees minus angle ABC/DCB).
Therefore, by the hypotenuse-leg congruence theorem (HL theorem), triangles ABD and CBD are congruent.
This means that BD is congruent to AC (the corresponding sides of congruent triangles are congruent).
Therefore, we have proven that BD is congruent to AC in trapezoid ABCD.

the scale factor between 0 and 1 ____ the size of an object, or makes it ___. A scale factor of 1 ______ the size of an object; that is, the size is ____. A scale factor greater than 1 ______ an object, or make it ___.
An object's size in real life and its size on a map or a blueprint are compared using a scale factor, which is a mathematical concept. The scale factor may exceed, fall short of, or be equal to 1.
What is scale factor and how is it calculated?The size of the object is decreased and becomes smaller if the scale factor is between 0 and 1. This is so because the scale factor only approximates the object's true size. The size of the thing on the map will be half that of the real object, for instance, if the scale factor is 0.5.
When the scale factor is 1, the object's size is said to remain constant. As a result, the map or blueprint is created using the same dimensions.
In other words, the map or blueprint is created at the exact same scale as the final product.
The size of the thing is enlarged and made larger if the scale factor is greater than 1. This is so because the scale factor is a multiple of the object's actual size. The size of an object on a map will appear twice as large as it is in reality, for instance, if the scale factor is 2.
In general, it's crucial to comprehend scale variables in order to appropriately depict an object's size on maps, blueprints, and other scaled representations.

An aquarium can be modeled as a right rectangular prism and it can hold 1120 cubic inches of water when it is full. Its length is 20 in and width is 8 in. Find the height of the aquarium in inches. Round your answer to the nearest tenth if necessary.
The height of the right rectangular prism aquarium is 7 inches
How to determine the height of the aquariumWe can use the formula for the volume of a right rectangular prism to find the height of the aquarium.
The formula is V = l x w x h,
Where V is the volume, l is the length, w is the width, and h is the height.
In this case, we know that the volume of the aquarium is 1120 cubic inches, the length is 20 inches, and the width is 8 inches.
Therefore, we can write:
1120 = 20 x 8 x h
Simplifying the right side of the equation, we get:
1120 = 160h
Dividing both sides by 160, we obtain:
h = 1120/160 = 7
