(x1/6)3 simplify the expression

Answer:

Step-by-step explanation:

The formal definition of a common difference is d = a_(n + 1) - a_n)

so

d = ?

a_(n+1) = a_2 = 14

a_n      = a_1 = 24

d = 14 - 24

d = - 10

-10

In the question, it is asking you to find the common difference between the numbers 24, 14, 4,...

In order to find the common difference between the numbers, we would nee to find the change between them.

In other words, we need to find out how much it's changing by between each number.

When you look at the sequence 24, 14, 4, you would know that it is decreasing each time. This means that the common difference would be a negative number.

Now, we need to figure out how much it is decreasing by.

When you subtract 24 and 14, [tex]24-14=10[/tex], you would get 10. When you subtract 24 by 10, you would get 14. So we know that the difference would be -10.

We can also check the next number. When you subtract 14 by 4, [tex]14-4=10[/tex], you would get 10. Then, when you subtract 14 by 10, you would get 4.

This means that the common difference of the sequence is -10

Answer:

Jesse will spend 0.68$ for 1.3 lbs of lettuce. Jesse will spend about 0.46$ on a single head of lettuce.

Step-by-step explanation:

Answer:

$0.68 for 1.3 pounds of lettuce

$0.46

Step-by-step explanation:

Multiply .52 by 1.3 since its $0.52 per pound,

0.52*1.32 - 0.676

Since its money round to the nearest cent, so its $0.68

1 pound = 16 ounces

So first you have to find how much it costs for 1 ounce.

So divide 0.52 by 16

0.52/16 = 0.0325 for one ounce

Then multiply 0.0325 by 14 since its 14 ounces.

0.0325*14 = 0.455

Then round to the nearest cent since its money, so its $0.46

Natasha could have 9 red apples and 4 green apples, or 10 red apples and 3 green apples.

To determine the number of red and green apples Natasha could have, we need to consider the given information. Natasha has a total of 13 apples, and she has more red apples than green apples.

Let's assume that Natasha has r red apples and g green apples. We know that r + g = 13, since she has a total of 13 apples.

Given that she has more red apples than green apples, we can say that r > g.

Now, we need to find the possible values of r and g that satisfy these conditions. We can use trial and error to find the values that work:

Based on our analysis, Natasha could have either 9 red apples and 4 green apples, or 10 red apples and 3 green apples.

Answer:

i) sin(2x) = [tex]-\frac{\sqrt{3}}{2}[/tex]

ii) cot(x+360) = [tex]-\frac{\sqrt{3}}{3}[/tex]

iii) sin(x-180) = [tex]\frac{\sqrt{3}}{2}[/tex]

Step-by-step explanation:

sec(x) = 2

Since cos(x) is reciprocal of sec(x), this means:

cos(x) = [tex]\frac{1}{2}[/tex]

cosec(x) is negative , this means sin(x) is also negative. The only quadrant where cos(x), sec(x) are positive and sin(x), cosec(x) are negative is the 4th quadrant. Hence the terminal arm of the angle x is in 4th quadrant.

Part i)

sin(2x) can be simplified as:

sin(2x) = 2 sin(x) cos(x)

First we need to find the value of sin(x). According to Pythagorean identity:

[tex]sin^{2}(x)=1-cos^{2}(x)\\\\ sin(x)=\pm \sqrt{1-cos^{2}(x)}[/tex]

Since, angle is in 4th quadrant, sin(x) will be negative. So considering the negative value of sin(x) and substituting the value of cos(x), we get:

[tex]sin(x)=- \sqrt{1-cos^{2}(x)}\\\\ sin(x)=-\sqrt{1-(\frac{1}{2})^{2}}\\\\ sin(x)=-\frac{\sqrt{3}}{2}[/tex]

So,

[tex]sin(2x)=2 \times -\frac{\sqrt{3} }{2} \times \frac{1}{2}\\\\ sin(2x)=-\frac{\sqrt{3}}{2}[/tex]

Part ii)

We have to find cot(x + 360)

An addition of 360 degrees to the angle brings it back to the same terminal point. So the trigonometric ratios of the original angle and new angle after adding 360 or any multiple of 360 stay the same. i.e.

cot(x + 360) = cot(x)

[tex]cot(x) = \frac{cos(x)}{sin(x)}\\[/tex]

Using the values, we get:

[tex]cot(x)=\frac{\frac{1}{2}}{-\frac{\sqrt{3}}{2} }\\\\ cot(x)=-\frac{\sqrt{3}}{3}[/tex]

Part iii)

We need to find the value of sin(x - 180)

sin(x - 180) = - sin(x)

Addition or subtraction of 180 degrees changes the angle by 2 quadrants. The sign of sin(x) becomes opposite if the angle jumps by 2 quadrants. For example, sin(x) is positive in 1st quadrant and negative in 3rd quadrant.

So,

sin(x - 180) = [tex]-(-\frac{\sqrt{3}}{2}) = \frac{\sqrt{3}}{2}[/tex]

Answer:

The answer is 3x^2+7x+2

Step-by-step explanation:

Multiply each term of the second bracket with the first bracket.

We can write:

(x+2)(3x+1)= 3x(x+2)+1(x+2)

By multiplying the terms we get:

=3x^2+6x+x+2

Now simplify by combining like terms:

=3x^2+7x+2

Thus the answer is 3x^2+7x+2....

Answer:

3x² + 7x + 2

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

x(3x + 1) + 2(3x + 1) ← distribute both parenthesis

= 3x² + x + 6x + 2 ← collect like terms

= 3x² + 7x + 2

Answer:

The volume is 36 inches cubed.

Step-by-step explanation:

The volume of a rectangular prism is W*L*H.

You are given the H=3i, W=2 in, and L=6 in.

So now we plug into our formula for the volume of a rectangular prism which will result in 2*6*3=12*3=36.

The volume is 36 inches cubed.

Answer: [tex]36\ in^3[/tex]

Step-by-step explanation:

The volume of a rectangular prism can be calculated with this formula:

[tex]V=lwh[/tex]

Where "l" is the lenght, "w" is the width and "h" is the height.

In this case we know that this rectangular solid is 3 inches high, 6 inches long and 2 inches wide. Then:

[tex]h=3\ in\\l=6\ in\\w=2\ in[/tex]

Then, substituting these values into the formula, we get that its volume is:

[tex]V=(6\ in)(2\ in)(3\ in)\\\\V=36\ in^3[/tex]

The domain is (-5, infinity).  There's no graph for x ≤ -5.

The range is [2, infinity).

Answer:

C. The domain is [-k, ∞), and the range is [C, ∞).

Step-by-step explanation:

To be able to answer this question we first need to understand what exactly are the domain and range of a function. Domain and Range can be defined as the following,

Domain: are all the possible input values a function can recieve, displayed as the x-coordinates on a graph.

Range: are all the possible output values that a function can spit out, displayed as the y-coordinates on a graph.

With this understood, we can look at the graph and easily point out the domain and range as the following values.

Domain being [-5,∞) ..... closed bracket because the value is included

Range being [2, ∞) ..... infinity values always take an open parenthesis

Based on this information we can safely assume the answer is C. The domain is [-k, ∞), and the range is [C, ∞).

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Answer:

h(x) = 6x² - 10x - 4

Step-by-step explanation:

f(x)g(x) = (2x - 4)(3x + 1)

Each term in the second factor is multiplied by each term in the first factor

2x(3x + 1) - 4(3x + 1) ← distribute both parenthesis

= 6x² + 2x - 12x - 4 ← collect like terms

= 6x² - 10x - 4

To find h(x), which is the product of f(x) and g(x), one must perform a binomial multiplication. The resulting function after simplification is h(x) = 6x² - 10x - 4.

The student is asking for the product of two functions, f(x) and g(x), defined as F(x)=2x-4 and G(x)=3x+1 respectively. To find the new function h(x), which is the result of multiplying f(x) and g(x) together, we use the following process:

h(x) = f(x) × g(x)

This translates into h(x) = (2x - 4)(3x + 1). We need to perform a binomial multiplication (also known as FOIL - First, Outside, Inside, Last) to combine these two expressions.

Applying binomial multiplication, we get:

Combining these terms, we get the final expression for h(x):

h(x) = 6x² + 2x - 12x - 4

Simplifying further:

h(x) = 6x² - 10x - 4

Step-by-step explanation:

bearing in mind that a diagonal line from the center of a square will give us an isosceles triangle, Check the picture below.

Answer:

The area of this polygon is 98.1 yd²

Step-by-step explanation:

Check the image below.

The diagonal line from the corner of a square to the center of this one will shape an isosceles triangle.

The Pythagoras theorem give us the following formula:

A² + A² = H²

Both "A" are the sides and H is the hypotenuse, seeing the figure, the diagonal coincide with the hypotenuse and the measure is 7 yd.

A² + A² = 72  

2A² = 49

A²= 49/2

A²= 24. 5

A=√24.5

A= 4.95 yd

Knowing that the diagonal ends up in the center of the square, we assume that the side of the triangle (“A” side) is the half of the side of the square, then this last one is 2A. Bearing in mind that square have all of the sides with the same measure, the four sides have a 2A size.

2A = 2(4.95) =9.9 yd

Each side of the square measures 9.9 yd

The area of a square is  

Side²= (2A)2²

(9.9)²= 98.1 yd²

The area of this polygon is 98.1 yd²
