Answer:

y-4=-2/5(x+5)

Step-by-step explanation:

Points slip form is y-y₁=m(x-x₁)

Since you have a graph we can see the line goes down 2 and over 5. Since the slope is going downwards it is a negative slope. This mean m=-2/5. Then pick any point on the line ( I chose (-5,4)) and plug it in for y₁ and x₁.

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

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

[tex]\pi = 180[/tex]

[tex] \frac{17 \times 180}{12} = \frac{3060}{12} = 255[/tex]

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:

x = 13

Step-by-step explanation:

Vertical angles are always congruent (equal)

⇒ ∠A =∠B

⇒ (8x - 12) = (6x + 14)

⇒ 2x = 26

⇒ x = 13

Angle A and Angle B are vertical angles . If mAngle A = ( 8x - 12 )° and mAngle B = ( 6x + 14 )°, then find the value of x .

We have to find the value of x

Concept of this question belongs to vertical angles i.e. vertical angle are always equal .

[tex] \pink{\boxed {Therefore , \: value \: of \: x \: i s \: 13}}[/tex]

We are verifying our answer by putting the value of x in given Angle A and Angle B ,

Therefore , our answer is correct .

Answer:

-5

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}.

∠ MAJ = 50°

Step-by-step explanation:

the chord- chord angle KAJ is half the sum of the of the arcs intercepted by the angle and its vertical angle, that is

∠ KAJ = [tex]\frac{1}{2}[/tex] (KJ + LM ) = [tex]\frac{1}{2}[/tex] (190 + 70)° = [tex]\frac{1}{2}[/tex] × 260° = 130°

then

∠ MAJ and ∠ KAJ are adjacent angles and sum to 180° , so

∠ MAJ + 130° = 180° ( subtract 130° from both sides )

∠ MAJ = 50°

Answer:

max = 150

Step-by-step explanation:

the maximum height is the value of the y- coordinate of the vertex.

given a quadratic equation in standard form : y = ax² + bx + c = 0 ( a ≠ 0 )

then the x- coordinate of the vertex is

x = - [tex]\frac{b}{2a}[/tex]

- 16x² + 64x + 86 = 0 ← is in standard form

with a = - 16 and b = 64 , then

[tex]x_{vertex}[/tex] = - [tex]\frac{64}{-32}[/tex] = 2

substitute x = 2 into the quadratic for corresponding y- coordinate

- 16(2)² + 64(2) + 86 = - 16(4) + 128 + 86 = - 64 + 128 + 86 = 150

vertex = (2, 150 )

then maximum height is 150 units

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.
