Answer:

Step-by-step explanation:

The range of values for x is {2, 26, 2.5, 5} in the given case where we have to enter values.

To provide a range of values for x based on the given information, we need to solve the equation 2x+10 = 14, 62, 15, and 20.

Let's solve the equation for each given value: 1. 2x+10 = 14:

Subtract 10 from both sides of the equation: 2x = 4

Divide both sides of the equation by 2: x = 2 2. 2x+10 = 62:

Subtract 10 from both sides of the equation: 2x = 52

Divide both sides of the equation by 2: x = 26 3. 2x+10 = 15:

Subtract 10 from both sides of the equation: 2x = 5

Divide both sides of the equation by 2: x = 2.5 4. 2x+10 = 20:

Subtract 10 from both sides of the equation: 2x = 10

Divide both sides of the equation by 2: x = 5

Therefore, the range of values for x is {2, 26, 2.5, 5}.

The circumference of the base of the silo that the farmer plans to build to store chicken feed is 28.8 ft.

A cone is simply a 3-dimensional geometric shape with a flat base and a curved surface pointed towards the top.

The volume of a cone is expressed as;

V = (1/3)πr²h

Where r is radius of the base, h is the height of the cone and π is constant pi ( π = 3.14 )

A circle is simply a closed 2-dimensional curved shape with no corners or edges.

The circumference of a circle is expressed mathematically as;

C = 2πr

Where r is radius and π is constant pi ( π = 3.14 )

Given the data in the question;

We substitute our values into the expression above find the radius of the base of the silo.

V = (1/3)πr²h

132ft³ = (1/3) × 3.14 × r² × 6ft

132ft³ = 6.28ft × r²

r² = 132ft³ / 6.28ft

r² = 21.0191ft²

r = √21.0191ft²

r = 4.58ft

Now, since the radius of the base of the silo is 4.58ft, the circumference of the base will be;

C = 2πr

C = 2 × 3.14 × 4.58ft

C = 28.8ft

Therefore, the circumference of the base of the silo that the farmer plans to build to store chicken feed is 28.8 ft.

Answer:

14w

Step-by-step explanation:

Width = w

Length is 6 time its width. so, multiply w by 6

length = 6*w = 6w

Perimeter of rectangle = 2* (length + width)

                                        = 2*(6w + w)

                                        = 2*7w

                                         = 14w

The dimension of the rectangle 18 feet by 13feet

A rectangle is a 2 dimensional shape having two sides.

Area of a rectangle = length * width

Given the following parameters

Length = x + 8

Width = x + 3

Area = 234ft^2

Substitute the given parameters into the formula

(x+8)(x+3) = 234
x² + 3x + 8x + 24 = 234

x² + 11x = 234 - 24
x² + 11x = 210

x² + 11x - 210 = 0

Factorize

x² + 21x - 10x - 210 = 0

x(x+21) - 10(x+21) = 0
x - 10 = 0
X = 10

Leength = x + 8

Length = 18 feet

Width = x + 3

Width = 3 + 10
Width = 13feet

Hence the dimension of the rectangle 18 feet by 13feet

By taking a quotient, we will see that the number of guests is 540.

Because we know that each guest ate a fixed amount of pizza, and there was no pizza left, we know that the number of guests will be equal to the quotient between the total number of pizzas bought, and the amount of pizza that each guest ate.

This is:

[tex]N = \frac{90}{1/6}[/tex]

We can rewrite that quotient as:

[tex]N = \frac{90}{1} / \frac{1}{6} = \frac{90*6}{1*1} = 540[/tex]

So the number of guests is 540.

The equation h(t) = -16t² + 24t is an illustration of a quadratic model

The equation that represents the path of the kick ball is given as

h(t) = -16t² + 24t

The fielder catches the ball at a height of 3 ft above the ground.

This means that:

h(t) = 3

So, we have:

-16t² + 24t = 3

Hence, the equation when the fielder catches the ball is -16t² + 24t = 3

In (a), we have:

-16t² + 24t = 3

Rewrite as:

-16t² + 24t - 3 = 0

Next, we determine the solutions of -16t² + 24t - 3 = 0 using a graphing technology

From the graph (see attachment), we have the following solutions

t = 0.14 and t = 1.36

Hence, the fielder will catch the ball after 0.14 seconds or 1.36 seconds

Answer:

f⁻¹(x) =

Step-by-step explanation:

Given function,

→ f(x) = 5x - 6

We are supposed to find ths inverse of the given function. Consider the function, y = f(x).

→ y = 5x - 6

Add 6 to both sides.

→ y + 6 = 5x - 6 + 6

Solve the equation.

→ y + 6 = 5x

Division both sides by 5.

→ y + 6/5 = 5x/5

Solve the equation.

→ (y + 6)/5 = x

Can be re-written as,

→ x = (y + 6)/5

Now, recall f(x) = y, this implies x = f⁻¹(y).

→ f⁻¹(y) = (y + 6)/5

So the final answer is:

→ f⁻¹(x) = (x + 6)/5
