A circle is a curve sketched out by a point moving in a plane. The area of the circular paper is more than the area of the square.

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

The arc length of radius 6 inches is equal to,

Length of the Arc of a quarter = 2πr×(1/4) = 2×π×6×0.25 =0.9448 inches

The area of the circular paper = πr² = π×6×6 = 113.097²

The area of the square with a side of 6 inches = 36 in²

Therefore, the area of the circular paper is more than the area of the square.

Answer:

8 pounds

Step-by-step explanation:

3 ft board = 2lb

12 ft board is 4 times more so

2x4 = 8 lb

Step-by-step explanation:

we have a right-angled triangle :

the Hypotenuse (baseline opposite of the 90° angle) is the 850 ft cable from the top of the tower down to the point on the ground 360 ft away from the tower.

then the ground distance (360 ft) and the height of the tower are the 2 legs.

so, we can use Pythagoras

c² = a² + b²

with c being the Hypotenuse.

in our case

850² = 360² + height²

height² = 850² - 360² = 592,900

height = 770 ft

the tower is 770 ft tall.

Answer:

770 feet

Solving

Answer:

0 People initially had the cold.

6 People will have it after 2 days.

Step-by-step explanation:

To find out how many people had it initially, plug 0 in for x (implying 0 days later.)

C= 1*3(0)

C= 1*0

C=0

Nobody had the cold initially.

To find out how many people had it after 2 days, plug 2 in for x. (implying 2 days later.)

C= 1*3(2)

C= 1*6

C=6

Therefore 6 people had the cold after 2 days.

1. The regular expression for the language L={ all words in which a's must follow the symbol b} is \(^(b*(ab*)*)*a*$\).

2. The regular expression for the language L={ all words that have at least one occurrence of the string abc in them } is .*abc.*.

3. The grammar for the language L={ all words that start with c and end with c and have only a's and b's in between} is S -> cXc, X -> ε | aX | bX.

4. The grammar for the language L={ all words using symbols a,b,c in which every b follows the symbol a} is S -> ε | aSb | aA | c, A -> ε | aAb | aA | c. The grammar is ambiguous.

1. The regular expression \(^(b*(ab*)*)*a*$\) specifies that the word should start and end with any number of 'b' and 'a' in any order, and only 'a' should follow 'b'.

2. The regular expression .*abc.* matches any word that contains the substring 'abc' at least once.

3. The grammar S -> cXc, X -> ε | aX | bX generates words that start with 'c', followed by a sequence of 'a' or 'b', and ends with 'c'. Only 'a' and 'b' symbols are allowed in between.

4. The grammar S -> ε | aSb | aA | c, A -> ε | aAb | aA | c allows for words that can have multiple occurrences of 'a' followed by 'b', 'a' followed by 'a' or 'b', or just the symbol 'c'. This grammar is ambiguous because a single sentence can have multiple parse trees or interpretations.

An ambiguous grammar in a programming language can lead to different interpretations of code, resulting in confusion, inconsistencies, and difficulties in parsing and understanding the code.

Unintended or unexpected behavior can arise due to ambiguity, making it challenging to write reliable and predictable programs. To ensure clarity, correctness, and ease of interpretation, it is crucial to have an unambiguous grammar for a programming language.

Answer:

51in

Step-by-step explanation:

Just set the equations of line OP and line O'P' equal to one another, then solve for x.

ie: 3(2x+3)=(8x-5)

To solve for x, distribute first. Then, subtract 6x from each side. Then, add 5 to each side.

ie: 6x+9=8x-5

ie: 14=2x

Now divide by 2.

ie: 7=x

Now that you have your x value, plug it back into one of the equations and solve for the measure of line OP. To check you answer, plug 7 for x into the equation where they are set equal, then solve them both and if the end result is true (51=51) it is correct.

Answer:

A

Step-by-step explanation:

The graph of f(x) = 4x is a parabola that opens upwards. Shifting the graph 1 unit upwards, reflecting the graph about the y-axis, and shifting the graph 6 units left will all result in new graphs that are transformations of the original graph. Therefore:

a. Shifting f(x) 1 unit upward: y = 4x + 1

b. Reflecting f(x) about the y-axis: y = -4x

c. Shifting f(x) 6 units left: y = 4(x - 6)

The equations of the graphs that result from the given transformations:

a. Shifting f(x) 1 unit upward.

The graph of f(x) = 4x is a parabola that opens upwards. Shifting the graph 1 unit upwards means that all the points on the graph are moved 1 unit upwards. The new equation of the graph is:

y = 4x + 1

b. Reflecting f(x) about the y-axis.

Reflecting the graph of f(x) = 4x about the y-axis means that the x-coordinates of all the points on the graph are negated. The new equation of the graph is:

y = -4x

c. Shifting f(x) 6 units left.

Shifting the graph of f(x) = 4x 6 units left means that all the x-coordinates of all the points on the graph are decreased by 6. The new equation of the graph is:

y = 4(x - 6)

When booking a show for a future date, it is normal practice for the booking agent to collect a 50% advance fee when the advances are not given for shows. This is to ensure that the performer is fully committed to performing at the event and to cover any expenses that may be incurred in the process.

The advance fee is usually non-refundable and is paid by the promoter or venue operator to the booking agent. This is to show their commitment to the performer and to demonstrate that they are serious about booking them for the event. The remaining balance is then usually paid on the day of the performance or shortly after.

The booking agent should also ensure that all parties involved in the booking are aware of the terms and conditions and have signed a contract or agreement to confirm their agreement.

Venn diagrams are used in sets in mathematics to group the union and intersection of subsets.

We are told that;

Number of students that enjoyed country = 32

Number of students that enjoyed jazz = 14

Number of students that enjoyed both country and jazz = 8

Now, the number of the students that enjoyed country and jazz should be the intersection of both circles in the venn diagram.

Secondly number of students that listened to only country = 32 - 8 = 24

Number that listened to only jazz = 14 - 8 = 6

The exponential function to model the population of Valley View is \(y = 1800(1.012)^t\).

What is an exponential function?

The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.

An exponential function is written in the form -

\(y=ab^t\)

Here, y is the function, a is the base value b is the rate and t is time period.

The number of people in Valley view is 1800. So, the base is a = 1800.

The function y depicts the towns population.

Each decade the population grows by 12%.

The growth rate per year is = 12 / 10

The growth rate is 1.2%

The value for b will be = 1 + r

b = 1 + 1.2/100

b = 1 + 0.012

b = 1.012

So, the exponential equation will be -

\(y = 1800(1.012)^t\)

Therefore, the exponential equation is \(y = 1800(1.012)^t\).
