36 houses are left to be sold.

We need to convert 1/4 and 2/5 into decimals. We do this by dividing the numerator by the denominator:

1 ÷ 4 = 0.25

2 ÷ 5 = 0.4

Now, we can set up this equation to find out how many were sold in the first month:

0.25 x 80 = 20

Now, 20 isn't the answer, it is 60 houses left, because 80 - 20 = 60.

Let's do the next one:

0.4 x 60 = 24

60 - 24 = 36

36 houses are left to be sold.

Yes, the equation defines the value of y in terms of x which is ±10x.

A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation. Equations come in a variety of forms, including linear, quadratic, cubic, and others.

Given, the equation defines y as a function of x.

100x² = y²

Hence,

Y² = (10x)²

Taking square root on both sides.

y = ±10x

Since the value of the y is in the term of x. Therefore, The value of y is defined in terms of x, which is 10x, in the equation.

Answer: 0.25 or 1/4

Hope this helps :)

Step-by-step explanation:

Answer:

0.25 or 1/4

Step-by-step explanation:

1/2 as a decimal is 0.50 and that squared is 0.25, which as a fraction is 1/4.

The value of y for the linear differential equation is:

y= [5(x³+6x²+12x)/3(16+32x+24x²+8x³+4x⁴)]  + c₁ /(16+32x+24x²+8x³+x⁴)

You should know that a differential equation is in which we find the value of y with respect to x

The given parameter is

(x-2)² dy/dx = 5-8y-4xy

Differentiate y with respect to x to have

y= [5(x³+6x²+12x)]/[3(16+32x+24x²+8x³+x⁴)] + c₁/(16+32x+24x²+8x³+x⁴)]

Recall that the differential equation is (x-2)² dy/dx = 5-8y-4xy

Solving the Ordinary Differential Equation we have

y= y= [5(x³+6x²+12x)]/[3(16+32x+24x²+8x³+x⁴)] + c₁/(16+32x+24x²+8x³+x⁴)]

In conclusion, the value of y is:  y= [5(x³+6x²+12x)]/[3(16+32x+24x²+8x³+x⁴)] + c₁/(16+32x+24x²+8x³+x⁴)]

The velocity of a shell shot into the air with a velocity of 58 m/s, its height in meters after t seconds is given by y=58t - 20t² is 38 m / s.

When anything is moving, its velocity tells us how quickly that something's location is changing from a certain vantage point and as measured by a particular unit of time.

If a point moves along a path and covers a certain distance in a predetermined amount of time, its average speed over that period of time is equal to the distance covered divided by the travel time. A train traveling 100 kilometers in two hours, for instance, is doing it at an average speed of 50 km/h.

Given:

Height equation, y = 58t - 20t²,

The time, t = 0.5 seconds,

The initial velocity, u = 58 m/s,

Calculate the height at 0.5 sec,

y = 58 × 0.5 - 20 × 0.5²

y = 24 m

Calculate the acceleration at 0.5 sec by using the motion equation given below:

[tex]s = ut+1/2at^2[/tex]

24 = 58 × 0.5 + 1 / 2 × a × 0.5²

-5 = 0.125 × a

a = - 40 m / s²

Calculate the velocity by using the formula given below,

[tex]v = u + at[/tex]

v = 58 + (-40) × 0.5

v = 38 m /s

Therefore, the velocity of a shell shot into the air with a velocity of 58 m/s, its height in meters after t seconds is given by y = 58t - 20t² is 38 m / s.

Answer: The function F(x) = 32 + 1.87x converts Celsius temperatures to Fahrenheit temperatures. To confirm this, you can plug in a few different values for x (the Celsius temperature) and see if the corresponding value of F(x) (the Fahrenheit temperature) is correct.

For example, if x = 0, the function gives us F(0) = 32 + 1.87 * 0 = 32, which is the correct conversion from Celsius to Fahrenheit for 0 degrees Celsius.

If you want to find a formula for the function C that converts Fahrenheit temperatures to Celsius temperatures, you can start by rearranging the formula for F(x). The Fahrenheit temperature is equal to the Celsius temperature plus 32, multiplied by 1.8.

If we solve for the Celsius temperature, we get:

x = (F - 32) / 1.8

This is the formula for the function C that converts Fahrenheit temperatures to Celsius temperatures. To use this function, you would plug the Fahrenheit temperature into the function as the input, and it will give you the corresponding Celsius temperature as the output.

For example, if you want to convert 100 degrees Fahrenheit to Celsius, you would plug 100 into the function as the input:

C(100) = (100 - 32) / 1.8 = 37.78 degrees Celsius.

Step-by-step explanation:

4x + 3 = 3(2x - 5)

4x + 3 = 6x - 15

3 = 2x - 15

2x = 18

x = 9

4(9) + 3

= 39

39 * 4 = 156

Hope it helps!

Answer: 156 inches

Step-by-step explanation:

So we know that all of the sides are equal to each other.

Now we need to know what x equals.

4x + 3 = 3(2x -5)

4x + 3 = 6x - 15

3 = 2x -15

18 = 2x

9 = x

Plug 9 into one of the equations.

4(9) + 3

36 + 3 = 39

39 * 4 = 156

Perimeter = 156 inches

It is unknown if a mathematical sentence is true or false since it uses variables, which is known as a "open sentence" in mathematics. On the other hand, a closed sentence is a mathematical statement that is known to be either true or untrue.

Given:

|x| + 3 > 3

|x| > 3- 3

|x| > 0

Now, The open sentence is an absolute inequality, so we start by analyzing the inequality sign > 0 means that, the x-values of the inequality is not less than 0.

The ratio y/x is not constant (k) for all the data points, then y does not vary directly with x.

What is the constant of variation?

The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another.

We have,

         x         y

         2         10

         4         24

         6         36

To determine whether y varies directly with x, you need to see if the ratio of y to x is constant for all the data points.

If y varies directly with x, then the ratio y/x will be constant for all the data points. In this case, you can write an equation for the direct variation in the form y = kx, where k is the constant of variation, which is equal to the ratio y/x.

If the ratio y/x is not constant for all the data points, then y does not vary directly with x.

so, let's see the k constant of variation,

k =  y/x

k = 2/10 =1/5

k = 4/24 = 1/6

k = 6/36 = 1/6

so,  k = 1/5, k=1/6, k=1/6.

Hence, the ratio y/x is not constant (k) for all the data points, then y does not vary directly with x.

The polynomial function, y= (x+4)(x-2)²(x+7) has three different roots

From the question, we have the following parameters that can be used in our computation:

y = (x+4)(x-2)^2(x+7)

Rewrite the equation properly

So, we have the following representation

y= (x+4)(x-2)²(x+7)

Set the factor to 0

So, we have

x + 4 = 0, x - 2 = 0 and x + 7 = 0

When these equations are solved, we have

x = -4 , x = 2 and x = -7

See that the counts of the values of x is 3

The amount of money Dana Jones have after 7 years with an investment of $ 1100 at 5 % interest compounded continuously is $ 1560.97

What is Compound Interest?

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

When compounded continuously , the Compound Interest Amount is calculated by the formula ,

A = Pe^rt

Given data ,

Let the investment be P

The value of P = $ 1100

The rate of interest r = 5 %

The number of years t = 7 years

The Compound Interest Amount when compounded continuously is calculated by the formula ,

A = Pe^rt

Substituting the values in the equation , we get

A = 1100 x e ^ 0.05 x 7

A = 1100 x e ^ 0.35

A = 1100 x 2.718 ^ 0.35

A = 1100 x 1.419067

A = $ 1560.97

Therefore , the value of the amount is A = $ 1560.97

Hence ,

The link between two variables known as "inverse variation" occurs when the value of one variable rises while the value of the other variable falls.

Here, we have

Inverse variations look like this: y = k/x

We need to make our own inverse variation given y = 18  and x = 7. We can plug this into the standard inverse variation with variables.

y = k/x

18 = k/7

k = 126

We've determined that k =126. Now we have what it takes to create an inverse variation. This is our final equation:

y = 126/x
