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

Hence, it has three different roots

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.

What are Inverse variations?

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

We still need to find what y equals when x is 6. Let's plug in 6 for x

y = 126/6

y = 21

Hence, the value of y is 21, when x = 6.

4x + 3 = 6x - 15

3 = 2x - 15

2x = 18

x = 9

4(9) + 3

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

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.

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.

Step-by-step explanation:

A parabola is a curve that is shaped like a U. The direction in which a parabola opens depends on the sign of the coefficient of the x^2 term in the equation defining the parabola. If the coefficient is positive, the parabola opens upwards. If the coefficient is negative, the parabola opens downward.

In the equation y = -x + 2, the coefficient of the x^2 term is 0, so the direction of the parabola does not depend on it. However, the coefficient of the x term is -1, which is negative. This means that the parabola defined by this equation opens downward.

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 ,
