Answer:

n = 75

Step-by-step explanation:

Step 1: Write equation

-n = -75

Step 2: Divide both sides by -1

n = 75

Step 3: Check

Plug in n to verify it's a solution.

Answer:

  adjust the weights until balance is achieved

Step-by-step explanation:

Start with all of the beam weights in their 0 position.

Move the heaviest weight to successive positions farther from 0 until the beam falls. Move it back one.

Move the next-heaviest weight to successive positions farther from 0 until the beam falls. Move it back one.

Move the lightest weight along the scale away from 0 until the beam is centered in the space.

The weight of the object in the tray is the sum of the marks on the scales associated with the three weights.

_____

It helps if the device is "calibrated" before you add anything to the pan. When the pan is empty and all beam weights are in their 0 position, the beam should be centered in its space. If not, adjust the zeroing device until it is.

The attached picture shows a typical laboratory triple-beam balance. It is capable of measuring weights up to 610 grams with a resolution of 0.1 grams or better.

The complete table of the algae area is:

Day   1     2   3   4   5   6

Area  1/2  1   2   4   8   16

The initial area is given as;

A(1) = 1/2 square meters

When it doubles every day, we have:

A(n) = 2 * A(n - 1) where A(1) = 2

So, we have the following values

A(2) = 1/2 * 2 = 1

A(3) = 1 * 2 = 2

A(4) = 2 * 2 = 4

A(5) = 4 * 2 = 8

A(6) = 8 * 2 = 16

Hence, the complete table is:

Day   1     2   3   4   5   6

Area  1/2  1   2   4   8   16

The minimum possible product of three different numbers in the set {-8, -6, -4, 0, 3, 5, 7} is -192.

We can first arrange the numbers in increasing order in order to get the smallest possible product of the three different numbers in the given set.

{-8, -6, -4, 0, 3, 5, 7} → {-8, -6, -4, 0, 3, 5, 7}

The three lowest figures are -8, -6, and -4. These three integers added together yield:

-8 × -6 × -4 = -192

Any other three numbers in the set will have a product that is either positive or contains positive numbers, in which case it will be bigger than -192. As a result, the smallest possible product of the trio of numbers in this set is -192.

1. We can calculate the slope (m): m = 498.7

2. We have the equation of the trend line: y = 498.7x - 1009.75

3.  The forecasted sales for year 5 is approximately 1483.75.

4.  The forecasted sales for year 6 is approximately 1982.45.

To use the Linear Trend Equation for forecasting sales in year 5 and 6, we need to calculate the equation of the trend line first. The formula for a linear trend line is:

y = mx + b

Where:

y = dependent variable (sales)

x = independent variable (year)

m = slope of the line

b = y-intercept

To find the slope (m) and y-intercept (b), we can use the least squares method or the method of linear regression. However, since we only have four data points, we'll use a simplified version of the linear regression formula:

m = [(nΣxy) - (ΣxΣy)] / [(nΣx^2) - (Σx)^2]

b = (Σy - mΣx) / n

Let's calculate the values:

n = number of data points = 4

Σx = sum of years = 1 + 2 + 3 + 4 = 10

Σy = sum of sales = 230 + 235 + 239 + 243 = 947

Σxy = sum of (year * sales) = (1 * 230) + (2 * 235) + (3 * 239) + (4 * 243) = 4861

Σx^2 = sum of (year^2) = (1^2) + (2^2) + (3^2) + (4^2) = 30

Now we can calculate the slope (m):

m = [(nΣxy) - (ΣxΣy)] / [(nΣx^2) - (Σx)^2]

= [(4 * 4861) - (10 * 947)] / [(4 * 30) - (10^2)]

= [19444 - 9470] / [120 - 100]

= 9974 / 20

= 498.7

Next, let's calculate the y-intercept (b):

b = (Σy - mΣx) / n

= (947 - (498.7 * 10)) / 4

= (947 - 4987) / 4

= -4039 / 4

= -1009.75

Now we have the equation of the trend line:

y = 498.7x - 1009.75

To forecast sales in year 5, substitute x = 5 into the equation:

y = 498.7 * 5 - 1009.75

= 2493.5 - 1009.75

= 1483.75

Therefore, the forecasted sales for year 5 is approximately 1483.75.

To forecast sales in year 6, substitute x = 6 into the equation:

y = 498.7 * 6 - 1009.75

= 2992.2 - 1009.75

= 1982.45

Therefore, the forecasted sales for year 6 is approximately 1982.45.

The range of c for which the optimal solution does not change is c = 2.

To determine the range of c for which the optimal solution does not change, we need to identify the values of c for which the objective function remains parallel to the original objective function 2x1 + 5x2.

In the original problem, the objective function is Z = 2x1 + 5x2.

If we change the coefficient of x1 to c, the new objective function becomes Z = cx1 + 5x2.

To keep the optimal solution unchanged, we need the direction of the objective function to remain the same. This means that the slope of the new objective function should be the same as the original objective function (2x1 + 5x2).

The slope of the new objective function is equal to the coefficient of x1, which is c. Therefore, for the optimal solution to remain the same, the value of c must be equal to 2.

So, the range of c for which the optimal solution does not change is c = 2.

Answer:

[tex] \overline{XY} = 3 [/tex]

[tex] \overline{ZW} = 2 [/tex]

They are not congruent

Step-by-step explanation:

Length of segment XY:

Coordinate of X = -8

Coordinate of Y = -5

[tex] \overline{XY} [/tex] = |-8 -(-5)| = |-8 + 5| = 3

Length of ZW:

Coordinate of Z = 4

Coordinate of W = 6

[tex] \overline{ZW} [/tex] = |4 - 6| = 2

[tex] \overline{XY} [/tex] ≠ [tex] \overline{ZW} [/tex], therefore, they are not congruent.

Answer:

To find an expression that is equivalent to `y = x^2 + 8x + 18`, we can try to complete the square, factorize, or use the quadratic formula.

Completing the square:

We can add and subtract (8/2)^2 = 16 to the right-hand side of the equation to get:

y = x^2 + 8x + 18 + 16 - 16

y = (x + 4)^2 + 2

So an equivalent expression for `y = x^2 + 8x + 18` is `y = (x + 4)^2 + 2`.

Factorizing:

We can try to factorize the quadratic expression on the right-hand side of the equation. To do this, we need to find two numbers whose sum is 8 and whose product is 18. These numbers are 2 and 6, so we can write:

y = x^2 + 2x + 6x + 18

y = (x^2 + 2x) + (6x + 18)

y = x(x + 2) + 6(x + 3)

y = (x + 2)(x + 6)

So an equivalent expression for `y = x^2 + 8x + 18` is `y = (x + 2)(x + 6)`.

Using the quadratic formula:

We can use the quadratic formula to solve for x in the equation `y = x^2 + 8x + 18`. The quadratic formula states that for an equation of the form `ax^2 + bx + c = 0`, the solutions for x are given by:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

In our case, a = 1, b = 8, and c = 18. Substituting these values into the quadratic formula, we get:

x = (-8 ± sqrt(8^2 - 4(1)(18))) / 2(1)

x = (-8 ± sqrt(4)) / 2

x = -4 ± 1

So the solutions for x are x = -5 and x = -3. If we substitute these values into the original equation `y = x^2 + 8x + 18`, we get:

When x = -5, y = (-5)^2 + 8(-5) + 18 = 5 - 40 + 18 = -17

When x = -3, y = (-3)^2 + 8(-3) + 18 = 9 - 24 + 18 = 3

So an equivalent expression for `y = x^2 + 8x + 18` is `y = (x + 5)(x - 3)`.

To find the composite functions (fog)(x) and (gof)(x) using the given functions f(x) = 2x - 4 and g(x) = 2, we substitute one function into the other based on the order indicated. (fog)(x) = 0, (gof)(x) = 2, (fog)(7) = 0, and (gof)(7) = 2.

The value of (fog)(7) and (gof)(7) can be determined by evaluating the composite functions at x = 7.

a. To find (fog)(x), we substitute g(x) into f(x): (fog)(x) = f(g(x)) = f(2). Since g(x) = 2, we replace g(x) with 2 in f(x): f(2) = 2(2) - 4 = 4 - 4 = 0. Therefore, (fog)(x) = 0.

b. To find (gof)(x), we substitute f(x) into g(x): (gof)(x) = g(f(x)) = g(2x - 4). Since f(x) = 2x - 4, we replace f(x) with 2x - 4 in g(x): g(2x - 4) = 2. Therefore, (gof)(x) = 2.

c. To find (fog)(7), we evaluate (fog)(x) at x = 7: (fog)(7) = 0.

d. To find (gof)(7), we evaluate (gof)(x) at x = 7: (gof)(7) = 2.

Therefore, (fog)(x) = 0, (gof)(x) = 2, (fog)(7) = 0, and (gof)(7) = 2.
