The inverse of the equation y = log(1/4)[tex]x^{5}[/tex] is x = 1/([tex]y^{(log(4)/5)}[/tex]).

What is an inverse equation?

To find the inverse of the equation y = log(1/4)[tex]x^{5}[/tex], we can follow these steps:

Step 1: Interchange the x and y variables to obtain x = log(1/4)[tex]y^{5}[/tex].

Step 2: Solve for y in terms of x. To do this, we need to isolate the y term on one side of the equation. We can start by taking both sides of the equation to the power of 1/5:

[tex]x^{1/5}[/tex] = log(1/4)y

y = [tex](1/4)^{(1/log(x^(1/5)))}[/tex]

Step 3: Simplify the expression. Recall that [tex]a^b^{c}[/tex], so we can rewrite the exponent in the denominator as log([tex]x^{1/5}[/tex]) = (1/5)log(x). Substituting this into the expression for y, we get:

y = [tex](1/4)^{(1/(log(x^(1/5))))}[/tex]

To calculate the monthly lease payment, we need to use the formula:

Monthly Payment = Depreciation + Finance Charge

The depreciation represents the portion of the car's value that is lost during the lease period, while the finance charge is the interest charged on the lease.

First, let's calculate the depreciation:

MSRP = $51,500

Residual Value = 49% of MSRP = 0.49 x $51,500 = $25,235

Depreciation = (Negotiated Price - Residual Value - Down Payment) / Lease Term

Depreciation = ($49,000 - $25,235 - $4,000) / 36 = $541.53

Next, let's calculate the finance charge:

Lease Balance = (Negotiated Price - Down Payment) - Residual Value

Lease Balance = ($49,000 - $4,000) - $25,235 = $19,765

Money Factor = Annual Interest Rate / 2400

Money Factor = 7.8% / 2400 = 0.00325

Finance Charge = Lease Balance x Money Factor

Finance Charge = $19,765 x 0.00325 = $64.26

Finally, we can calculate the monthly payment:

Monthly Payment = Depreciation + Finance Charge

Monthly Payment = $541.53 + $64.26 = $605.79

Therefore, the monthly lease payment is $605.79.

What is rectangle?

A rectangle is a two-dimensional geometric shape with four straight sides and four right angles (90 degrees). It is a type of quadrilateral, which means it has four sides. The opposite sides of a rectangle are equal in length, and the adjacent sides are perpendicular to each other.

The formula for calculating the area of a rectangle is A = l x w, where "A" is the area, "l" is the length, and "w" is the width. The perimeter of a rectangle can be calculated by adding the lengths of all four sides, which is given by the formula P = 2(l + w).

Rectangles are commonly found in many aspects of everyday life, such as in buildings, furniture, electronic devices, and books. They can be used in architecture and engineering for creating stable and functional structures. In mathematics, rectangles are often used in geometry and algebraic expressions, as well as in statisticalanalysis and graphing.

Here we have a rectangle with length 16m and breadth 13 m.

Now, area of the rectangle is length × breath = 13×16 = 208 m².

And here we also have two square parts with side 4 m .

So, area of the square is side × side = 4×4 = 16 m².

Now, numbers of square are 2.

So, total area of two square is (2×16) = 32 m².

If we will subtract the total area of two square from area of the rectangle then we will get the area of shaded region .

So, area of the shaded region [tex] = 208 - 32 = 176 \: {m}^{2} [/tex]

Therefore, area of the shaded region is 176 m² .

Here compound shapes are one rectangle and two squares.

Answer:

Step-by-step explanation:

If the value of the tent depreciates by 12% each year, then its value at the end of each year is 100% - 12% = 88% of its value at the beginning of the year.

So after the first year, the value of the tent will be:

$866 x 0.88 = $761.28

After the second year, the value of the tent will be:

$761.28 x 0.88 = $670.58

After the third year, the value of the tent will be:

$670.58 x 0.88 = $590.99

Therefore, the tent will be worth $590.99 in 3 years, to two decimal places.

Answer:

After one year, the value of the tent will be worth 100% - 12% = 88% of its original value.

After two years, the value of the tent will be worth 88% - 12% = 77.44% of its original value.

After three years, the value of the tent will be worth 77.44% - 12% = 68.1472% of its original value.

To find out how much the tent will be worth in 3 years, we can use the following formula:

Value after 3 years = original value x (1 - depreciation rate)^number of years

Value after 3 years = $866 x (1 - 0.12)^3 = $518.98

Therefore, the tent will be worth $518.98 in 3 years.

What is rectangle?

A rectangle is a type of quadrilateral with four sides and four right angles (90-degree angles). It is characterized by two pairs of parallel sides of equal length.

Let's represent the width of the brick walkway by "x" feet.

Then the dimensions of the entire rectangle including the brick walkway will be [tex]$(25+2x)$[/tex] feet by [tex]$(13+2x)$[/tex] feet.

The area of the rectangle with the walkway will be:

[tex]$$(25+2x)(13+2x)$$[/tex]

We know that the area of the walkway itself is 287 square feet. So we can set up the following equation:

[tex]$$(25+2x)(13+2x) - 25\cdot 13 = 287$$[/tex]

Simplifying and solving for x, we get:

[tex]$$4x^2 + 86x - 216 = 0$$[/tex]

Using the quadratic formula, we get:

[tex]$x = \frac{(-86 \pm \sqrt{86^2 - 4(4)(-216)})}{2(4)}$$[/tex]

[tex]$$x \approx 2.061 \text{ or } x \approx -26.311$$[/tex]

The probability of selecting a blue or green ball on the first draw is 2/3 or approximately 0.67.

What is probability ?

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, where 0 indicates that the event is impossible, and 1 indicates that the event is certain to occur. If an event has a probability of 0.5, it means that the event is equally likely to occur or not occur. The probability of an event can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
Probability is an important concept in mathematics, statistics, and many other fields, as it allows us to make predictions and decisions based on the likelihood of certain outcomes.

According to the question:
The total number of balls in the bag is:

6 blue balls + 5 yellow balls + 4 green balls = 15 balls

The probability of selecting a blue or green ball on the first draw can be found by dividing the number of blue and green balls by the total number of balls:

P(blue or green) = (number of blue balls + number of green balls) / (total number of balls)

P(blue or green) = (6 + 4) / 15

P(blue or green) = 10 / 15

P(blue or green) = 2/3

Therefore, the probability of selecting a blue or green ball on the first draw is 2/3 or approximately 0.67.
