Answer:

Answer 1 & 4 IS CORRECT

Step-by-step explanation:

1.  The composite figure consists of two rectangular pyramids.

4. The total volume is 45 units3.

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

The x in f(x) will change to (x - 3)

= (x - 3) + 5

The new function g(x) = x + 2

Hence, Option D is correct

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:

$765.85

Step-by-step explanation:

The furniture store bought it for $425 (the starting price). They mark it up by 70%.

To solve, multiply 425 with 70%, and then add the number you get to the original price:

425 x 0.70 = 297.5

297.5 + 425 = 722.5

Now, multiply the price gotten by 6%:

722.5 x 0.06 = 43.35

Add the tax amount to the total amount:

43.35 + 722.5 = 765.85

$765.85 is the amount paid by Angela.

Answer:

765.85

Step-by-step explanation:

To find the new price, find the mark up

mark up = 425 * 70%

425 *.7

297.5

Add this to the original price to find the new price

425 + 297.5

722.50

Now we need to find the tax

722.5 * 6%

722.5 *.06

43.35

Add this to the sale price

722.5 +43.35

765.85

Answer:

yes, no, no

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.

3 ) f(-x) = -4x - 4 ≠ f(x)

Therefore, the function f(x) = 4x - 4 is not an even even function.

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

In order to solve your question, we're going to need to find the sales price of the boots.

Lets gather some important information from the question.

Important information:

Original price is $120

40% off

With the information above, we can find the sales price.

Since we know that the original price of the boots is $120, and the boots are 40% off, we're going to need to find how much of 120 is 40% and then subtract it to get our sales price.

[tex]120*.40=48\\\\120-48=72[/tex]

Once you're done solving, you should get 72.

This means that the sales price of the boots is $72.

$72 should be your FINAL answer.

Answer: $72

Step-by-step explanation:

10% of $120 = $12 so

40% is $48, subtracted from $120 = $72

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°

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]

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!

Answer:

Triangle

Step-by-step explanation:

A regular polygon of n sides has interior angles of:

a = 180 (n-2) / n

Given a = 60:

60 = 180 (n-2) / n

n = 3 (n-2)

n = 3n - 6

6 = 2n

n = 3

The polygon has three sides, so it's a triangle.

A regular polygon with each angle measuring 60° is an equilateral triangle.

A regular polygon is a polygon with all sides and angles equal. To find the type of polygon where each angle measures 60°, we use the formula for the measure of each interior angle of a regular polygon, which is (n-2) x 180° / n, where n is the number of sides.

Let's solve for n:

Set the angle measure formula to 60°: (n-2) x 180° / n = 60°

Multiply both sides by n to clear the fraction: (n-2) x 180° = 60n

Distribute 180°: 180n - 360° = 60n

Move the terms involving n to one side: 180n - 60n = 360°

Simplify: 120n = 360°

Divide both sides by 120: n = 3

Therefore, a regular polygon with each angle measuring 60° is an equilateral triangle.
