x + 9 = 37

To solve for x bring 9 to the right side by subtracting 9 to both sides (what you do on one side you must do to the other). Since 9 is being added on the left side, subtraction (the opposite of addition) will cancel it out (make it zero) from the left side and bring it over to the right side.

x + 9 - 9 = 37 - 9

x + 0 = 28

x = 28

Check:

28 + 9 = 37

37 = 37

n - 5 = 9

To solve for n you must add 5 to both sides (what you do on one side you must do to the other). Since 5 is being subtracted, addition (the opposite of subtraction) will cancel it out (make it zero) from the left side and bring it over to the right side.

n - 5 + 5 = 9 + 5

n + 0 = 14

n = 14

Check:

14 - 5 = 9

9 = 9

Hope this helped!

Step-by-step explanation:

* Lets explain how to restrict the domain of the quadratic function

- The quadratic function is two-to-one function

- The inverse of it is one-to-two which is not a function

- So we can not find the inverse of the quadratic function until restrict its

 domain

- We restrict the domain at the x-coordinate of the vertex of the function

∵ f(x) = (x - h)² + k is the standard form of the quadratic function, where

  (h , k) are the coordinates of its vertex

- To restrict the domain we put x > h for the right part of the parabola

  or x < h for the left part of the parabola

* Lets solve the problem

∵ f(x) = (x - 2)²

∵ f(x) = (x - h)² + k is the standard form of the quadratic function

∴ h = 2 and k = 0

∴ The vertex of the parabola is (2 , 0)

- We will restrict the domain at x = 2

∴ The domain of the function f(x) to have inverse is x > 2 or x < 2

* The restriction domain is x > 2 or x < 2

- To find the inverse of the function switch x and y and solve for the

  new y

∵ f(x) = (x - 2)²

∵ f(x) = y

∴ y = (x - 2)²

- Switch x and y

∴ x = (y - 2)²

- take square root for both sides

∴ ± √x = y - 2

- Add 2 for both sides

∴ ± √x + 2 = y

∴ [tex]f^{-1}=\sqrt{x}+2=====OR=====f^{-1}=-\sqrt{x}+2[/tex]

* For the domain x > 2 of f(x) the inverse is [tex]f^{-1}(x) = \sqrt{x}+2[/tex]

 For the domain x < 2 of f(x) the inverse is [tex]f^{-1}(x)=-\sqrt{x}+2[/tex]

For this case we have to:

Initial weight = [tex]123 \frac {1} {4} = \frac {4 * 123 + 1} {4} = \frac {493} {4} = 123.25 \ pounds[/tex]

Final weight =[tex]120 \frac {1} {2} = \frac {2 * 120 + 1} {2} = \frac {241} {2} = 120.5 \ pounds[/tex]

We subtract to know how many pounds he lost:

[tex]123.25-120.5 = 2.75[/tex]

So, Kerry lost 2.75 pounds.

ANswer:

Kerry lost [tex]2 \frac {3} {4}[/tex] pounds.

Answer:[tex]2.75\ pounds[/tex] or [tex]2\frac{3}{4}\ pounds[/tex]

Step-by-step explanation:

You can convert the mixed numbers to decimal numbers. Divide the numerator by the denominator of the fraction and add it to the whole number part:

[tex]123\ \frac{1}{4}\ pounds=(123+0.25)\ pounds=123.25\ pounds[/tex]

[tex]120\ \frac{1}{2}\ pounds=(120+0.5)\ pounds=120.5\ pounds[/tex]

To calculate how many pounds Kerry lost, you need to subtract his weigth of a month ago and his actual weigth.

Therefore, you get that he lost:

[tex]pounds\ lost=123.25\ pounds-120.5\ pounds[/tex]

[tex]pounds\ lost=2.75\ pounds[/tex] or [tex]2\frac{3}{4}\ pounds[/tex]

Answer:

587.18 in^2

Step-by-step explanation:

Given:

Diameter = d = 11 inches

Slant height = l =28.5 inches

Radius will be half of diameter

r = d/2 = 11/2 = 5.5 in

We know that the formula for surface area of cone is:

[tex]SA = \pi rl+\pi r^2\\Putting\ the\ values\\SA = (3.14*5.5*28.5)+(3.14 * 5.5 * 5.5 )\\= 492.195+94.985\\=587.18\ in^2[/tex]

Hence, second option is correct ..

Answer: second option.

Step-by-step explanation:

We know that we can calculate the surface area of a cone with this formula:

[tex]SA=\pi rl + \pi r^2[/tex]

Where "r" is the radius and "l" is the slant heigth.

We know that the radius is half the diameter, then the radius of this cone is:

[tex]r=\frac{11in}{2}\\\\r=5.5in[/tex]

Since we know tha radius and the slant height, we can substitute values into the formula, using 3.14 for π.

Therefore, we get:

 [tex]SA=(3.14)(5.5in)(28.5in) + (3.14)(5.5in)^2=587.18in^2[/tex]

Step-by-step explanation:

Given is the height of a ball as

[tex]h(t) = 8t^2+ 4t +125[/tex]

where t is time, in seconds, after the ball was thrown and h(t) is the corresponding height, in meters

When t=2.3, substitute this for t

h(2.3) = [tex]8(2.3)^2 +4(2.3)+ 125 \\=176.52m[/tex]

[tex]4x^2+28x + 48=\\4(x^2+7x+12)=\\4(x^2+3x+4x+12)=\\4(x(x+3)+4(x+3))=\\4(x+3)(x+4)[/tex]

Answer:

A

Step-by-step explanation:

Given

4x² + 28x + 48 ← factor out 4 from each term

= 4(x² + 7x + 12)

To factor the quadratic

Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term

The factors are + 4 and + 3, since

4 × 3 = 12 and 4 + 3 = 7, thus

x² + 7x + 12 = (x + 3)(x + 4) and

4x² + 28x + 48 = 4(x + 3)(x + 4) → A

Answer:

The maximum height  is 191.063 ft

Step-by-step explanation:

We can easily solve this question by plotting the graph of the equation below

h(t)=-16t^2+Vt+h

Where

h = initial height = 2ft

V = initial speed = 110 ft/s

t = time in seconds

Please, see attached image below

The maximum height corresponds to

191.063 ft

The maximum height the ball will attain is 115.02 feet.

The maximum height can be found by identifying the vertex of the quadratic equation representing the projectile's height.

Given the equation h(t) = -16t^2 + Vt + h, where V is the initial speed of the ball and h is the initial height, we substitute the given values V = 110 and h = 2 into the equation.

The equation becomes h(t) = -16t^2 + 110t + 2.

To find the maximum height, we need to find the vertex of this quadratic equation. The x-coordinate of the vertex can be found using the formula x = -b/2a, where a = -16 and b = 110. Plugging in these values, we have x = -110 / (2*(-16)) = 110/32 = 3.4375.

Now we can substitute this x-value back into the equation to find the y-coordinate of the vertex. h(3.4375) = -16(3.4375)^2 + 110(3.4375) + 2 = 115.02 feet.

Therefore, the ball will attain a maximum height of 115.02 feet.

Answer:A

Step-by-step explanation:

Think about it as a process of elimination.

It can't be "B' for the simple fact that "increased by'' is a term that is often used for addition problems.

It can't be "C" because, as previously stated, sum is a term that is used in addition problems.

It can't be "D" because this is a unit that you are using.

A. "c cubed" matches the expression c^3, which means raising c to the power of 3, not the other options.

The correct phrase that matches the expression c^3 is "A.) c cubed."

In mathematics, when you see an exponent of 3 (as in c^3), it indicates that you should multiply the base, c, by itself three times. This is commonly referred to as "c cubed." It signifies that you should raise c to the power of 3, meaning c * c * c. The other options are not accurate representations of c^3:

B.) "c increased by 3" does not involve exponentiation; it implies adding 3 to c.

C.) "the sum of 3 and c" is simply c + 3 and does not involve cubing.

D.) "3 cubed" represents 3^3, which equals 27, and is different from c^3.

Step-by-step explanation:

For odd functions : −f(x) = f(−x) for all x

For even functions :f(x) = f(−x) for all x

1) -f(x)= -2x^3 -2x

f(-x) = -2x^3-2x

yes

2 ) f(-x) = 5x^3 -4 ≠ f(x)

no

3  )  f(-x) = -4x -4   ≠ f(x)

no

1) [tex]f(-x) = -2x^3-2x[/tex]

The function [tex]f(x)=2x^3 + 2x[/tex] is odd function.

2 ) [tex]f(-x) = 5x^3 -4[/tex] ≠ f(x)

The function [tex]f(x) = -5x^3 - 4[/tex] is not even function.

3 ) f(-x) = -4x - 4 ≠ f(x)

The function f(x) = 4x - 4 is not an even even function.

If we obtain an expression that exists equivalent to f(x), we have an even function; if we obtain an expression that stands equivalent to -f(x), we contain an odd function; and if neither occurs, it is neither!

For odd functions :

−f(x) = f(−x) for all x

For even functions :

f(x) = f(−x) for all x

1) [tex]f(-x) = -2x^3-2x[/tex]

Therefore, the function [tex]f(x)=2x^3 + 2x[/tex] is odd function.

2 ) [tex]f(-x) = 5x^3 -4[/tex] ≠ f(x)

Therefore, the function [tex]f(x) = -5x^3 - 4[/tex] is not even function.

The equation of a function whose parent function, f(x) = x + 5, is shifted 3 units to the right will be; g(x) = x + 2

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that, the parent function f(x) = x + 5 is shifted 3 units to the right

If the function of x is translated horizontally to the right by h units, then the new function will be g(x) = f(x - h)

If the function of x is translated horizontally to the left by h units, then the new function will be g(x) = f(x + h)

Thus, f(x) = x + 5 is shifted 3 units to the right:

The new function is

g(x) = f(x - h)

Here h = 3

f(x) = x + 5

Final answer:

The correct equation after shifting the parent function f(x) = x + 5 three units to the right is g(x) = x + 2.

Explanation:

The equation of a function that is shifted 3 units to the right from its parent function, f(x) = x + 5, will incorporate that horizontal shift by subtracting 3 from the variable x before applying the rest of the function. Therefore, the new function, g(x), will have the form g(x) = (x - 3) + 5 which simplifies to g(x) = x + 2. This accounts for the fact that the input to the function is effectively 3 units greater for the same output as the original function.

Answer:

# m∠A = 65.3°

# m∠A = 25.8°

# m∠A = 22.7°

Step-by-step explanation:

* Lets revise the trigonometry function to solve the problem

- In any right angle triangle:

# The side opposite to the right angle is called the hypotenuse

# The other two sides are called the legs of the right angle

* If the name of the triangle is ABC, where B is the right angle

∴ The hypotenuse is AC

∴ AB and BC are the legs of the right angle

- ∠A and ∠C are two acute angles

- For angle A

# sin(A) = opposite/hypotenuse

∵ The opposite to ∠A is BC

∵ The hypotenuse is AC

∴ sin(A) = BC/AC

# cos(A) = adjacent/hypotenuse

∵ The adjacent to ∠A is AB

∵ The hypotenuse is AC

∴ cos(A) = AB/AC  

# tan(A) = opposite/adjacent

∵ The opposite to ∠A is BC

∵ The adjacent to ∠A is AB

∴ tan(A) = BC/AB

* Lets solve the problems

# In Δ ABC

∵ m∠B = 90°

∵ AB = 2.3 ⇒ adjacent to angle A

∵ BC = 5 ⇒ apposite to angle A

- To find m∠A use the tangent function because we have opposite

  and adjacent sides

∴ tan A = BC/AB

∴ tan A = 5/2.3 ⇒ use tan^-1 to find m∠A

∴ m∠A = [tex]tan^{-1}\frac{5}{2.3}=65.29756[/tex]

* m∠A = 65.3°

# In Δ ABD

∵ m∠B = 90°

∵ AB = 5.4 ⇒ adjacent to angle A

∵ DA = 6 ⇒ the hypotenuse

- To find m∠A use the cosine function because we have adjacent

  and hypotenuse sides

∴ cos A = AB/DA

∴ cos A = 5.4/6 ⇒ use cos^-1 to find m∠A

∴ m∠A = [tex]cos^{-1}\frac{5.4}{6}=25.84193[/tex]

* m∠A = 25.8°

# In Δ ABE

∵ m∠B = 90°

∵ EB = 2.4 ⇒ opposite to angle A

∵ EA = 6.8 ⇒ the hypotenuse

- To find m∠A use the sine function because we have opposite

  and hypotenuse sides

∴ sin A = EB/EA

∴ sin A = 2.4/6.8 ⇒ use sin^-1 to find m∠A

∴ m∠A = [tex]sin^{-1}\frac{2.4}{6.8}=22.6673[/tex]

* m∠A = 22.7°

we need two steps

Step 1: List the prime factors of each number.

Step 2: Multiply those factors all numbers have in common. If there are no common prime factors, the GCF is 1.

To find the GCF of 18 and 72

18 = 2 * 3* 3

72 = 2 * 2 * 2 * 3 * 3

Common prime factors 2, 3, 3

Therefore GCF = 2* 3 * 3 = 18

Your question asks to find the sales price of the boots.
