Step-by-step explanation:

absolute value of 225 = | 225 | = 225    

The y-intercept of [tex]\(12x + y^3 = 2\) is at \((0, \sqrt[3]{2})\).[/tex]

To find the y-intercept of the equation [tex]\(12x + y^3 = 2\)[/tex], we first need to understand what the y-intercept represents. The y-intercept is the point where the graph intersects the y-axis, which means the x-coordinate of this point is 0.

To find the y-intercept, we set [tex]\(x = 0\)[/tex] in the equation and solve for y:

[tex]\[12(0) + y^3 = 2\][/tex]

[tex]\[y^3 = 2\][/tex]

To solve for y, we take the cube root of both sides:

[tex]\[y = \sqrt[3]{2}\][/tex]

So, the y-intercept of the equation is [tex]\((0, \sqrt[3]{2})\).[/tex]

Answer:

B

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 1, 8) and (x₂, y₂ ) = (2, - 4) ← 2 points on the line

m = [tex]\frac{-4-8}{2+1}[/tex] = [tex]\frac{-12}{3}[/tex] = - 4 → B

Answer:

The slope of the given line is -4.

So, option (B) is correct.

Step-by-step explanation:

We know that, slope (m) of a line passing through points (x₁, y₁) and (x₂, y₂) is given by,

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Now, the given line passes through the point (-1, 8) and (2,-4).

So, (x₁, y₁) = (-1, 8) and (x₂, y₂) = (2, -4)

So, by using the above formula, we get

Slope(m) of the given line passing through (-1, 8) and (2, -4) is given by,

[tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}} = \frac{-4-8}{2-(-1)}[/tex]

[tex]\implies\;m = \frac{-12}{3}=-4[/tex]

∴The slope of the given line is -4.

Hence, option (B) is correct.

Answer:

1) Expression is

[tex](n+1)+(n^3+3n^2+2n)=n^3+3n^2+3n+1[/tex]

2) The standard form of the expression is

[tex]n^3+3n^2+3n+1=(n+1)^3[/tex]

3) The expression is

[tex]n^3+3n^2+3n+1=(n+1)^3[/tex]

Where [tex](n+1)^3[/tex] is the cube of the middle integer

Step-by-step explanation:

1) Given three consecutive integers are n. n+1, and n+2

Now multiplying the three consecutive integers

[tex](n)(n+1)(n+2)=(n^2+n)(n+2)[/tex]

[tex]=n^3+2n^2+n^2+2n[/tex]

[tex]=n^3+3n^2+2n[/tex]

Therefore [tex](n)(n+1)(n+2)=n^3+3n^2+2n[/tex]

Now adding the middle integer to the result of the multiplication.

ie, adding (n+1) to the result of the multiplication [tex]n^3+3n^2+2n[/tex]

[tex](n+1)+(n^3+3n^2+2n)=n+1+n^3+3n^2+2n[/tex]

[tex]=3n+1+n^3+3n^2[/tex]

Therefore [tex](n+1)+(n^3+3n^2+2n)=n^3+3n^2+3n+1[/tex]

2) Expression is [tex]n^3+3n^2+3n+1[/tex]

Now we simplify the above expression

[tex]n^3+3n^2+3n+1=n^3+3n^2(1)+3(n)(1)^2+1^3[/tex]

[tex]=(n+1)^3[/tex]      (by using [tex](a+b)^3=a^3+3a^2b+3ab^2+b^3[/tex]  , Here a = n and b=1)

[tex]n^3+3n^2+3n+1=(n+1)^3[/tex]

3) The expression is

[tex]n^3+3n^2+3n+1=(n+1)^3[/tex]

Where [tex](n+1)^3[/tex] is the cube of the middle integer.

ie, expression is equivalent to the cube of the middle integer

Step-by-step explanation:

Centroid Of A Triangle

The centroid of a triangle is the point where its three medians intersect. It is also the center of gravity of the triangle. The medians are lines that go from each vertex to the midpoint of the opposite side.

Given A(ax,by), B(bx,by), C(cx,cy) the points of the vertices, then the coordinates of the centroid [tex]P(x_c,y_c)[/tex] are

[tex]\displaystyle x_c=\frac{ax+bx+cx}{3}[/tex]

[tex]\displaystyle y_c=\frac{ay+by+cy}{3}[/tex]

The vertices are  (0,1) (2,6) (7,2), thus

[tex]\displaystyle x_c=\frac{0+2+7}{3}=3[/tex]

[tex]\displaystyle y_c=\frac{1+6+2}{3}=3[/tex]

The centroid is located at (3,3)

The coordinates of centroid are (3,3)

Step-by-step explanation:

The coordinates of centroid of a triangle are calculated by finding average of x-coordinates of vertices and the average of y-coordinates of vertices.

Given vertices are:

(0,1) (2,6) (7,2)

So,

x-coordinate of centroid:

[tex]x = \frac{0+2+7}{3}\\=\frac{9}{3}\\= 3[/tex]

y-coordinate of centroid:

[tex]y = \frac{1+6+2}{3}\\=\frac{9}{3}\\= 3[/tex]

Hence,

The coordinates of centroid are (3,3)

Answer:

16.00

Step-by-step explanation:

When you divide twenty percent(0.20) to 20.00 you will get sixteen or 4.00 dollars off

Answer:

Step-by-step explanation:

an = 6n - 13

If n  = 10  ,  a10 = 6*10 - 13 = 60-13 = 47

If n  = 11 ,  a11 = 6*11 - 13 = 66-13 = 53

If n  = 12  ,  a12 = 6*12 - 13 = 72-13 =  59

The formula to find the nth term of the sequence an, is a(n) = -13 + 6n

From the question, we have the following parameters that can be used in our computation:

a(10) = 47

a(11) = 53

a(12) = 59

a(13) = 65

The nth term of an arithmetic sequence can be represented as

a(n) = a(1) + (n - 1) * d

Where,

common difference,

d = 6

So, we have

a(n) = a(1) + (n - 1) * 6

Using the 12th term, we have

a(1) + (12 - 1) * 6 = 59

a(1)  = 59 - 66

a(1)  = -7

So,, we have

a(n) = -7 + (n - 1) * 6

Expand

a(n) = -13 + 6n

Hence, the formula to find an is a(n) = -13 + 6n

Answer:

The area of cardboard required is 40750 cm².

Step-by-step explanation:

Given:

Length (L) = 25 cm

Width (W) = 5 m = 5 × 100 = 500 cm

Height (H) = 15 cm

Area of the cardboard is same as the total surface area of the closed rectangular box.

Total surface area of the rectangular box is given as:

[tex]SA=2(LW+WH+LH)\\\\SA=2(25\times 500+500\times 15+15\times 25)\\\\SA=2(12500+7500+375)\\\\SA=2\times 20375=40750\ cm^2[/tex]

So, the area of cardboard required is 40750 cm².

After 16 hours, the charges will be same.

Step-by-step explanation:

Given,

Janet's upfront fee = $20

Charges per hour = $7.50

Let,

x be the number of hours.

J(x) = 7.50x+20

Lisa has no upfront fee.

Charges per hour = $8.75

L(x) = 8.75x

For the charges to be equal;

J(x) = L(x)

[tex]7.50x+20=8.75x\\20=8.75x-7.50x\\20=1.25x\\1.25x=20[/tex]

Dividing both sides by 1.25

[tex]\frac{1.25x}{1.25}=\frac{20}{1.25}\\x=16[/tex]

The cost of [tex]1\frac{3}{4}[/tex] pounds chocolate milk is $6.25 more than the cost of [tex]1\frac{3}{4}[/tex] pounds of Caramel.

Step-by-step explanation:

Given,

Cost of one pound of Caramels = $10.28

Cost of [tex]1\frac{3}{4}[/tex] pounds of Caramel = [tex]10.28*1\frac{3}{4}[/tex]

Cost of [tex]1\frac{3}{4}[/tex] pounds = [tex]10.28*\frac{7}{4}=\frac{71.96}{4}= \$17.99[/tex]

Final answer:

The cost for 1 3/4 pounds of milk chocolate is $6.25 more than the cost for 1 3/4 pounds of caramels, after calculating the total cost of each based on their per pound price.

Explanation:

To find out how much more the cost for 1 3/4 pounds of milk chocolate is than the cost for 1 3/4 pounds of caramels, we first need to calculate the cost of 1 3/4 pounds of each type of candy. Since the cost per pound of caramels is $10.28 and the cost per pound of milk chocolate is $13.85, we can set up our calculations as follows:

Total cost of caramels = 1.75 (pounds) * $10.28 (per pound) = $17.99

Total cost of milk chocolate = 1.75 (pounds) * $13.85 (per pound) = $24.24

Now, we subtract the total cost of caramels from the total cost of milk chocolate to find the difference:

Cost difference = $24.24 - $17.99 = $6.25

So, the cost for 1 3/4 pounds of milk chocolate is $6.25 more than the cost for 1 3/4 pounds of caramels.

Answer:

16 serving.

Step-by-step explanation:

Given: 3/4 cup servings.

Now, computing the number of serving in 12 cups of cherries.

Using unitary method to solve.

∴ Number of serving= [tex]total\ cups \times number\ of\ serving\ per\ cup[/tex]

Number of serving in one cup is [tex]\frac{4}{3}[/tex]

Number of serving in 12 cups = [tex]12\times \frac{4}{3} = 16 \ serving[/tex]

Number of serving in 12 cups= [tex]16\ serving[/tex]

∴ There are 16 serving is possible in 12 cups of cherries.

Final answer:

To calculate the number of 3/4 cup servings in 12 cups of cherries, divide 12 by 3/4, which equals 16 servings.

Explanation:

To determine how many 3/4 cup servings are in 12 cups of cherries, we can divide the total number of cups by the size of one serving.

First, we express the serving size and the total amount in the same units: 3/4 cup and 12 cups.

Next, we divide the total amount of cherries by the serving size: 12 cups ÷ 3/4 cup.

To perform the division, we can multiply 12 by the reciprocal of 3/4, which is 4/3 (12 × 4/3 = 16).

The result is that there are 16 servings of 3/4 cup in 12 cups of cherries.

Answer:

C. (1/3,-7); x=1/3; translated to the right 1/3 unit and down 7 units.

Step-by-step explanation:

The function is (1/3,-7); x=1/3; translated to the right 1/3 unit and down 7 units.

A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.

The parent function is:

g(x) = IxI

And we have:

f(x) = I6x - 2I - 7

Rearranging the function:

f(x) = 6Ix - 1/3I - 7

Then, now let's define some transformations:

If we start with g(x), a translation of N units to the right is:

f(x) = g(x - N)

if we start with g(x), a translation of N units up is:

f(x) = g(x) + N

A translation down would be:

f(x) = g(x) - N

And a vertical dilation of scale factor A is written as:

f(x) = A × g(x)

Then in this case we have:

A translation to the right of 1/3 units.

A dilation of scale factor 6.

A translation down of 7 units.

And the axis of symmetry will be when the absolute value part is equal to zero, or when

6Ix - 1/3I = 0

And that is when x = 1/3.

Therefore, the function is (1/3,-7); x=1/3; translated to the right 1/3 unit and down 7 units.

The value of each share decreased by $8.

Step-by-step explanation:

Number of shares of a certain stock Linda owned = 4

Total value of shares went down by = $32

So find the change in value of each share.

Solution:

Let the total value of each share in dollars be = [tex]x[/tex]

Value of 4 shares in dollars will be = [tex]4x[/tex]

The total value of shares went down by $32

So, new value of 4 shares = [tex]4x-32[/tex]

New value of each share = [tex]\frac{New\ value\ of\ total\ shares}{4}[/tex]

⇒ [tex]\frac{4x-32}{4}[/tex]

Splitting the denominators.

⇒ [tex]\frac{4x{{4}-\frac{32}}{4}[/tex]

⇒ [tex]x-8[/tex]

Original value of each share in dollars was = [tex]x[/tex]

New value of each share in dollars = [tex]x-8[/tex]

Thus, we can see that the value of each share decreased by $8.
