Using Algebraic expression, It will take approximately 3.47 years for an investment of $930,000 to double at an annual interest rate of 20%, compounded continuously.
Algebraic expression can be defined as combination of variables and constants.
The formula for continuous compound interest is given by:
[tex]A = Pe^{(rt)}[/tex]
where A is the amount after time t, P is the initial principal, r is the annual interest rate (as a decimal), and e is the constant 2.71828... (also known as Euler's number).
To find the time it takes for an investment to double at a 20% annual interest rate, we need to solve for t in the equation:
[tex]2P = Pe^{(rt)}[/tex]
Dividing both sides by P, we get:
[tex]2 = e^{(rt)}[/tex]
Taking the natural logarithm of both sides, we get:
[tex]ln(2) = rt ln(e)[/tex]
Since ln(e) = 1, we can simplify to:
ln(2) = rt
Solving for t, we get:
[tex]t = ln(2) / r[/tex]
Substituting P = $930,000 and r = 0.20, we get:
[tex]t = ln(2) / 0.20t = 3.47 years[/tex]
Therefore, it will take approximately 3.47 years for an investment of $930,000 to double at an annual interest rate of 20%, compounded continuously.

Write the linear equation that gives the rule for this table x 0 1 2 3 y 0 2 4 6
The linear equation that gives the rule for the given table x 0 1 2 3 y 0 2 4 6 is y = 2x.
What is linear equation?A linear equation is an equation of a straight line in the form of y = mx + b, where m represents the slope of the line, and b represents the y-intercept.
The slope of the linear equation can be found by calculating the change in y over the change in x:
slope=(y2 - y1) / (x2 - x1)
Taking (x1,y1) = (0,0) and (x2,y2) = (3,6),
slope=(6 - 0) / (3 - 0)
= 2
So slope of the linear equation is 2.
Next, we can use the point-slope form of the linear equation to find the equation of the line:
y - y1 = m(x - x1)
Taking (x1,y1) = (0,0) and m = 2,
y - 0 = 2(x - 0)
Simplifying, we get
y = 2x

This can be resolved with d = 25 miles by multiplying equation both sides by
Which equation can be used to find d?If Jen has driven 15 miles, and this is 3/5 of the total distance, we can use the following equation to find the total distance d:
15 = (3/5) * d
To solve for d, we need to isolate it on one side of the equation. We can start by dividing both sides of the equation by 3/5, which is the same as multiplying by its reciprocal, 5/3:
15 * (5/3) = d
Simplifying the expression on the left side, we get:
25 = d
Therefore, the total distance Jen needs to travel to get to the mall is 25 miles.
In summary, the equation that can be used to find the total distance d, given that Jen has driven 15 miles and this is 3/5 of the total distance, is:
15 = (3/5) * d
Which can be solved for d by multiplying both sides by 5/3, giving:
d = 25 miles

What are functions ?
Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
What are asymptotes ?
An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance. In other words, Asymptote is a line that a curve approaches as it moves towards infinity.
An asymptote of the curve y = f(x) or in the implicit form: f(x,y) = 0 is a straight line such that the distance between the curve and the straight line lends to zero when the points on the curve approach infinity.
There are three types of asymptotes namely:
1) Vertical Asymptotes
2) Horizontal Asymptotes
3) Oblique Asymptotes
The point to note is that the distance between the curve and the asymptote tends to be zero as it moves to infinity or -infinity.
What are domain of a function ?
The domain of a function is the set of values that we are allowed to plug into our function.
This set is the x values in a function such as f(x).

Therefore , the solution of the given problem of unitary method comes out to be 66.05, 66.33, 66.96, 66.83, 66.70, 66.03, 66.12, 65.64 for the closing values provided.
What is a unitary method?By utilizing what is explicitly learned thus far, taking variable of this global accessibility, and incorporating all crucial elements from previous expression research that utilized a particular approach, the goal can be achieved. It will be possible to get in touch with the entity again if the expected claim outcome actually happens; otherwise, both crucial processes will surely miss the statement.
Here,
We must take the average of the most recent three closing prices and repeat the procedure for the remaining prices in order to determine the 3-day SMA (Simple Moving Average).
Here's a step-by-step procedure:
=> Day 1: (66.21 + 65.90 + 67.05) / 3 = 66.05
=> Day 2: (65.90 + 67.05 + 67.03) / 3 = 66.33
=> Day 3: (67.05 + 67.03 + 66.80) / 3 = 66.96
=> Day 4: (67.03 + 66.80 + 66.65) / 3 = 66.83
=> Day 5: (66.80 + 66.65 + 66.65) / 3 = 66.70
=> Day 6: (66.65 + 66.65 + 65.80) / 3 = 66.03
=> Day 7: (66.65 + 65.80 + 65.92) / 3 = 66.12
=> Day 8: (65.80 + 65.92 + 65.21) / 3 = 65.64

What is the total cost of a $707 tablet computer that is on sale at 14% off if the local sales tax rate is 5%?
Answer:
$638.42
Step-by-step explanation:
First, we need to calculate the sale price of the tablet computer after the 14% discount is applied. To do this, we can multiply the original price by 0.86 (1 - 0.14), which gives:
Sale price = $707 x 0.86 = $608.02
Next, we need to add the sales tax to the sale price. To do this, we can multiply the sale price by 0.05 (5%), which gives:
Sales tax = $608.02 x 0.05 = $30.40
Finally, we can find the total cost of the tablet computer by adding the sale price and the sales tax, which gives:
Total cost = $608.02 + $30.40 = $638.42
Therefore, the total cost of the tablet computer with the discount and sales tax included is $638.42.

For what value of k will V= x+ k/x have a relative minimum at x = 3?
The value of k will make V = x + k/x have a relative minimum at x = 3 is k = 9
What is a relative minimum?A relative minimum of a function is the minimum value of the function in a particular interval.
Since we have the function V = x + k/x. We desire to find the value of k that will make V = x + k/x have a relative minimum at x = 3
So, to find the relative minimum of V, we differentiate with respect to x and equate to zero.
So, V = x + k/x
dV/dx = d(x + k/x)/dx
= dx/dx + kd(1/x)/dx
= 1 - k/x²
Equating dV/dx to zero, we have that
dV/dx = 0
⇒ 1 - k/x² = 0
1 = k/x²
k = x²
For a relative minimum at x = 3, substitute x = 3 into the equation. So, we have that
k = x²

Max is finding the perimeter of different-sized equilateral triangles.
The constant of proportionality between the side length and the perimeter of the equilateral triangle would be = 3.
What is constant of proportionality?The constant of proportionality is defined as the constant value that exists between two variables that are in a direct proportional relationship to each other.
For example, the constant of proportionality (k) between the side lengths and the perimeter of the equilateral triangle= y/X= 15/5= 3 or 24/8 = 3 or 27/9 = 3 or 30/10=3.
Therefore, the constant of proportionality which is the constant value existing between the two variables= 3.

construct a right angle triangle with one side 4cm and hypotenuse 5cm.
Answer:
See the explanation below.
Step-by-step explanation:
You need to calculate the remaining side.
Pythagorean theorem: c^2 = a^2 + b^2
=> 5^2 = 4^2 + b^2
b^2 = 25 - 16 = 9
b = √9 = 3
Draw a right triangle with the sides of 3cm and 4cm are perpendicular to form 90 degrees angle. Then connect the ends of 2 lines to form the hypotenuse which will be 5 cm long.

The triangles given are congruent as shown below.
What is Congruence of Triangles?Two or more triangles are said to be congruent if and only if sides and angles of one triangle is equal to the corresponding sides and angles of another triangle.
1) KL = LN [Since L is the midpoint of KN]
ML = LP [ Since L is the midpoint of MP]
∠MLK = ∠MLP [Vertically opposite pair of angles are equal.]
ΔMKL ≅ ΔPNL [Using the SAS Congruence Rule]
2) ∠BAD = ∠BCD [Given]
∠ABD = ∠CBD [Since BD bisects ∠ABC]
BD = BD [Common side]
ΔABD ≅ ΔCBD [Using AAS Congruence rule]
3) QR = ST [Given]
RS = TU [given]
QS = SU [Since S is the midpoint of QU]
ΔQRS ≅ ΔSTU [By SSS Congruence rule]
Hence the triangles are congruent.
