Answer:

Marginal Cost=Change in Total Cost/Change in Total Quantity

Step-by-step explanation:

Marginal cost is calculated by dividing the change in total cost by the change in quantity. Let us say that Business A is producing 100 units at a cost of £100. The business then produces at additional 100 units at a cost of £90. So the marginal cost would be the change in total cost, which is £90. Divided by the change in quantity, which is the additional 100 units. That gives us: £90/100, which equals £0.90 per unit as the marginal cost.

The expression to show the total number of songs on Iris's playlist after {w} weeks is → y = 120 + 4w.

In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that Iris has 120 songs on her playlist. Each week, she downloads 4 new songs.

We can write the expression to show the total number of songs on Iris's playlist after {w} weeks as -

y = 120 + 4w

Therefore, the expression to show the total number of songs on Iris's playlist after {w} weeks is → y = 120 + 4w.

To complete the hole on schedule the minimum amount of time the drill must continue to work is 18 hours

The rate of the drill for the remaining part of creating the whole is 56 feet per hour of digging

The remaining depth of the hole = the total hole - the depth before the rock

The remaining depth of the hole = 1012 - 2.75

The remaining depth of the hole = 1009.25

At a rate of 56 feet per hour the number of hours to dig 1009.25

56 feet = 1 hour

1009.25 feet = ?

cross multiplying

? * 56 = 1 * 1009.25

? = 1009.25/56

? = 18  

approximately 18 hours will take the drill to reach complete the hole

The values of x in the absolute value function 5 - 9|4 - 8x| = -103 are (b) {-1, 2}

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

5 - 9|4 - 8x| = -103

Subtract 5 from both sides of the equation

so, we have the following representation

- 9|4 - 8x| = -108

Divide both sides by -9

|4 - 8x| = 12

Remove the absolute bracket

Thisgives

4 - 8x = 12 or 4 - 8x = -12

So, we have

-8x = 8 or -8x = -16

Divide

x = -1 or x = 2

Hence, the values of x are (b) {-1, 2}

Answer:

Step-by-step explanation:

You want to identify the given shapes as a regular or irregular polygon, or neither.

A regular polygon is one that has all sides congruent, and all interior angles congruent. Polygon E is marked as having congruent sides and congruent angles.

Polygon E is a regular polygon.

A polygon is a closed figure formed by line segments connected end-to-end. A simple polygon is one that has no intersecting line segments. A convex polygon is one that has all interior angles measuring 180° or less.

Any simple polygon that is not a regular polygon is an irregular polygon.

Polygons A, B, D are irregular polygons.

A circle is not a polygon. Figure C is neither a regular polygon nor an irregular polygon.

Answer:

5.6

Step-by-step explanation:

We want to find the value of x, which is part of the segment that includes the length 10.

We need to use Power of Points, one property of which essentially says that if we have two intersecting chords such that they are each cut into two parts to make a and b, and c and d, then ab = cd (see attachment).

Here, we can say that a = 10, b = x, c = 7, and d = 8. Plug these in:

ab = cd

10 * x = 7 * 8

10x = 56

x = 56/10 = 5.6

The answer is 5.6.

Each diagonal has two parts (a, b, c, and d).

The formula is ab = cd

We have the values:

a = 10

b = x

c = 8

d = 7

Put these in the formula:

10x = (8)(7)

Solve for x.

10x = (8)(7)

10x = 56

10x/10 = 56/10

x = 5.6

Therefore, the answer is x = 5.6

Interior angles of a polygon = (sides - 2) × 180

Exterior angles are always 360

Please Mark as Brainliest if you found it helpful!

The measures of an exterior angle are 2520°, and an interior angle is 360° in the given regular polygon with 16 sides.

An interior angle is defined as an angle produced on the inside of a polygon by extending the sides of the polygon.

Interior angles of a polygon = (sides - 2) × 180°

To determine the measures of an exterior angle and an interior angle given a regular polygon with 16 sides.

Interior angles of a polygon = (sides - 2) × 180°

In this case, the number of sides is 16

Interior angles of a polygon = (16 - 2) × 180

Interior angles of a polygon = (14) × 180

Interior angles of a polygon = 2520

And, Exterior angles are always 360° in the regular polygon.

The number on the rectangles is zero. And the number on the triangles is negative 3.

Let 'R', 'T', and 'C' be the number on the rectangles, triangles, and circles, respectively.

There are 3 more characters on the rectangle than there are on the triangle. Three greater than the number on the rectangle is the number on the circle. The circle has the number 3 on it.

Then the equations are given below.

R = 3 + T            ...1

C = 3 + R           ...2

The number on the circles is 3. Put C = 3 in equation 2, then we have

Step-by-step explanation:

The amount remaining after 50 years is approximately 45.5% of the Initial amount, A₀.

The given exponential function represents the amount A(t) (in grams) of cesium-137 remaining after t years:

A(t) = A₀ * (1/2)^(t/30)

We are asked to find the initial amount A₀ and the amount remaining after 50 years.

1. Initial amount:

The initial amount, A₀, is the amount of cesium-137 present at t = 0 years. To find A₀, we substitute t = 0 into the equation:

A(0) = A₀ * (1/2)^(0/30)

A(0) = A₀ * 1

Since anything raised to the power of zero is 1, we have A(0) = A₀ * 1, which simplifies to A(0) = A₀.

Therefore, the initial amount of the sample is A₀.

2. Amount after 50 years:

To find the amount remaining after 50 years, we substitute t = 50 into the equation:

A(50) = A₀ * (1/2)^(50/30)

Now we can calculate the amount using the given formula:

A(50) = A₀ * (1/2)^(5/3)

To round the answer to the nearest gram, we evaluate the expression and round the result to the nearest gram:

A(50) = A₀ * 0.455

A(50) ≈ A₀ * 0.455

Therefore, the amount remaining after 50 years is approximately 45.5% of the initial amount, A₀.

The area of the segment is 9( π-2) units²

The area of a figure is the number of unit squares that cover the surface of a closed figure.

A segment is the area occupied by a chord and an arc. A segment can be a major segment or minor segment.

Area of segment = area of sector - area of triangle

area of sector = 90/360 × πr²

= 1/4 × π × 36

= 9π

area of triangle = 1/2bh

= 1/2 × 6²

= 18

area of segment = 9π -18

= 9( π -2) units²

therefore the area of the segment is 9(π-2) units²
