Answer:

In geometry, the circumference is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure.

Answer:

1. Circumference = 87.92

2.Circumference = 43.96

Step-by-step explanation:

The first problem it had a radius. So in order to find the circumference you will have to use the formula <em>2πr</em>. When you plug in the 14 yd in the radius spot it will look like <em>2</em><em>π</em><em>(</em><em>1</em><em>4</em><em>)</em><em> </em>when you solve it the answer will be 87.92

The second one has a diameter so the equation you will have to use is πd. Now you will have to plug the 14 cm where the diameter is which will look like <em>π</em><em>(</em><em>1</em><em>4</em><em>)</em><em> </em>when you solve it the answer will come out as 43.96

Q4. The diagram shows a triangle inside a rectangle.
Yanka [14]

The prove to show that the area of the shaded portion is 18x  - 30 is as follows: 3x² + 13x - 30 - 3x² + 5x = 18x  - 30

<h3>How to find the area of the shaded region?</h3>

The area of the shaded region can be represented as follows:

area of the shaded region = area of rectangle - area of triangle

Therefore,

area of the rectangle = (x + 6)(3x - 5)

area of the rectangle = 3x² - 5x + 18x - 30

area of the rectangle = 3x² + 13x - 30

area of triangle = 1 / 2 × 2x × 3x - 5

area of triangle = 3x² - 5x

Therefore,

area of the shaded portion =  3x² + 13x - 30 - 3x² + 5x

area of the shaded portion = 18x  - 30

What is the solution set of {x | x &lt; -3} ∩ {x | x &gt; 5}?
valentinak56 [21]

Answer:

the empty set  {∅}

Step-by-step explanation:

{x | x < -3} ∩ {x | x > 5} is giving us

(-∞, -3) intersecting (5, ∞).

Since those two intervals do not intersect the solution is the empty set

If the sequence 1, 6, 7, 13, 20, ... were to follow the same pattern as the Fibonacci sequence, what are the next three terms?
Alex787 [66]

The Fibonacci sequence is generated by starting with the numbers 0 and 1 (or 1 and 1) and obtaining the next number by adding them together. All successive numbers are the sum of the previous two.

0 + 1 = 1

1 + 1 = 2

1 + 2 = 3

2 + 3 = 5

and so on.

For this sequence, we have

1 + 6 = 7

6 + 7 = 13

7 + 13 = 20

13 + 20 = 33

20 + 33 = 53

33 + 53 = 86

A factory produces widgets whose length must be within 1.5 mm of an ideal length of 47 mm. A factory supervisor wants to mark ru
Nat2105 [25]

Using absolute value, it is found that:

  • The situation is described by the following equation: |l - 47| = 1.5
  • The markings should be between 45.5mm and 48.5mm.

---------------------------

The definition of the <em>absolute value function</em> is as follows:

|x| = x, x \geq 0

|x| = -x, x < 0

----------------------------

The length should be set to 47mm with an allowance of 1.5mm, which means that <u>the absolute value of the difference between the length and 47 should be 1.5</u>, thus:

|l - 47| = 1.5

----------------------------

The solutions are:

l - 47 = -1.5 \rightarrow l = 45.5

l - 47 = 1.5 \rightarrow l = 48.5

The markings should be between 45.5mm and 48.5mm.
