After simplification, the value of expression is, (x + 1) / (2x - 1).

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

The expression is,

⇒ 10x² + 10x / 20x² - 10x

Now, We can simplify as;

⇒ (10x² + 10x) / (20x² - 10x)

Step-by-step explanation:

Let's call the time it took Pat and Rich to drive to the beach "x".

The time it took them to drive back was twice as long, so it took 2x hours.

The total time spent traveling was x + 2x = 3x hours.

Since they spent 9 hours traveling, 3x = 9 hours.

So, x = 9 hours / 3 = 3 hours.

This means it took Pat and Rich 3 hours to drive to the beach and 2 * 3 = 6 hours to drive back.

The rate of change of the hypotenuse is given as follows:

dh/dt = 2 in/sec.

The Pythagorean Theorem states that for a right triangle, the length of the hypotenuse squared is equals to the sum of the squared lengths of the sides of the triangle.

The hypotenuse is then given as follows:

h² = x² + y².

For this problem, the hypotenuse has the value given as follows:

h² = 33² + 44²

h = square root(33² + 44²)

h = 55.

Applying implicit differentiation, the rate of change of the hypotenuse is obtained by the equation as follows:

h dh/dt = x dx/dt + y dy/dt.

Replacing the values, the rate of change is calculated as follows:

55dh/dt = 33 x 10 - 44 x 10

55dh/dt = -110

As a result, his monthly payment of $289.41 for a loan of $43,000 compounded monthly over 20 years at an APR of 2.4% will be required.

By dividing initial principal by the risk premium, the time it has been and other factors, simple interest is determined. Simple return equals principal plus interest plus hours is the technique used in marketing. The easiest way to compute interest is by using this method. The most typical method for calculating this is as a portion of the principal amount. For example, if he borrowed $100 from a buddy and agrees to pay back the loan at 5% interest, he will just pay his share of the 100% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and you must lend money when you lend it. Typically, interest is determined as an indicator of the overall of the loan total. The loan's interest is the name given to this percentage.

given

Assuming a specific interest rate (r), principal (p), and number of times the interest is compounded annually (n), we can calculate the total amount owed on a loan (A) as follows:

A = p(1+ r/n) nl

Because in our example, n = 12 (monthly), p = $43,000, r = 2.4% = = 0.024, and t = 20 years.

A = $69457.89.

$289.41 per month for a 20-year term.

The total area of all the pieces would be: -  x² + y² + 2xy = (x + y)².

This tile collection is composed of four tiles: two squares, each with sides of length x, and two rectangles, each with sides of length x and y.

The total area of all of the pieces can be expressed algebraically as A = x² + 2xy.

This expression can also be written as A = x² + xy + xy.

This tile collection is an example of a two-dimensional shape composed of two squares and two rectangles.

By adding the areas of each of these shapes, we can calculate the total area of the tile collection.

The area of each square is x², and the area of each rectangle is xy.

Adding these three expressions together gives us the total area, A = x² + 2xy.

Answer:

y = 5x

where

y = number of fence posts that Edwin installs
x = number of hours that Edwin takes to install y posts

Step-by-step explanation:

Let y = number of fence posts that Edwin installs in x hours

We have the relation:

y ∝ x where ∝ is the symbol for is-proportional-to

We can rewrite this as an equation using the constant of proportionality,k:

y =kx

Given y = 40 fences, x = 8 hours we get

40 = k(8) = 8k

or, switching sides

8k = 40

k = 40/8 = 5

So Edwin can install 5 fences per hour

Plugging this into the equation of proportionality

y = 5x

The dimensions of the rectangular field are given as follows:

The perimeter of a rectangle is given by twice the sum of the length and the width of the rectangle, as follows:

P = 2(l + w).

For this problem, the perimeter is of 582 yards, hence:

2(l + w) = 582

l + w = 291.

The length of the field is 4 yards less than quadruple the width, hence:

l = 4w - 4.

Then the width is obtained as follows:

4w - 4 + w = 295

5w = 295

w = 295/5

w = 59.

The length is obtained as follows:

l = 4 x 59 - 4

l = 232 yards.

The solution satisfying y1(0)=14 and y2(0)=-3 are y1(t) = 14 * e^(tln(14/13)) / (1 + (14/13)e^(tln(14/13))) and y2(t) = -3 * e^(tln(-3/2)) / (1 + (-3/2)e^(tln(-3/2)))

The logistic equation is a non-linear ordinary differential equation that models the growth of populations over time.

The solution to the logistic equation with initial conditions y1(0)=14 and y2(0)=-3 is given by (from a graphing tool):

y1(t) = 14 * e^(tln(14/13)) / (1 + (14/13)e^(tln(14/13)))

y2(t) = -3 * e^(tln(-3/2)) / (1 + (-3/2)e^(tln(-3/2)))

Note: ln is the natural logarithm function.

The time t when y1(t)=7 can be found by solving for t in the equation y1(t) = 7.

From the graphing tool, we have

t = 1.08 when y1(t) = 7

he solution y2(t) becomes infinite when the denominator of the equation becomes zero.

This occurs when -3/2 * e^(t * ln(-3/2)) = -∞.

This can be written as t * ln(-3/2) = ∞, which occurs when t approaches positive infinity.

Answer:

The water cycle involves the continuous movement of water on, above, and below the surface of the Earth. In the cycle, water can exist in three states: liquid, solid, and gas. During evaporation, liquid water changes into water vapor, the gaseous state of water, as it heats up and turns into steam. When water vapor cools, it can condense back into liquid form, such as when it forms clouds. Precipitation, such as rain or snow, occurs when water droplets in the clouds become heavy enough to fall from the sky. When precipitation reaches the ground, some of it may flow into rivers and streams and eventually make its way to the ocean. Some of it may also be taken up by plants or seep into the ground, becoming part of the groundwater system. Eventually, the water in the groundwater system may evaporate back into water vapor and start the cycle over again.

The percentage of vehicles whose speeds are between 52 miles per hour and 70 miles per hour is 75%.

A statistical principle known as the empirical rule, also known as the three-sigma rule or 68-95-99.7 rule, holds that with a normal distribution, almost all observed data will fall within three standard deviations of the mean.

Given, The mean speed of a sample of vehicles along a stretch of highway is 64 miles per​ hour, with a standard deviation of 4 miles per hour.

[tex]\mu = 64[/tex] and [tex]\sigma = 4[/tex].

Now, 52 is 3 standard deviations away from the mean so 50% of the data falls into this category and 70 is 1.5 standard deviations away from the mean and 25% of the data falls into this category.

Therefore, 75% of the vehicles would fall into this category.

The collection of values that can be plugged into a function's domain are called its parameters. The x values for a function like f are contained in this collection (x).

                           The collection of numbers that the function assumes is known as its range. The values that the function outputs when we enter an x value are in this set.
