The area of the shaded which is obtained using the composite figure formed the shaded region and the area under the curve of the specified function is; (2·π - 3·√3)/2 square units

A composite figure is one that is composed of two or more simpler figures.

The area can be considered of comprising of a composite figure of the area under the curve of the function and the area of the shaded region

The function representing the curve under the shaded region can be presented as follows;

y = 3·cos(x) + 1

The interval specified under the curve can be expressed as follows;

0 ≤ x ≤ π/3

Therefore, the area under the curve can be found as follows;

\(\int\limits^\frac{\pi}{3} _3 {3\cdot cos(x) + 1} \, dx = [3\cdot sin(x) + x]^{\frac{\pi}{3} }_0 = 3\cdot sin(\frac{\pi}{3} ) + \frac{\pi}{3} - 0 = 3\cdot sin(\frac{\pi}{3} ) + \frac{\pi}{3}\)

sin(π/3) = (√3)/2

Therefore; 3·sin(π/3) + π/3 = 3·(√3)/2 + π/3 = (2·π + 9·√3)/6

The area of the rectangle = (4 - 0) × (π/3 - 0) = 4·π/3

The area of the shaded region = Area of the rectangle - Area under the curve of the specified function

Therefore, area of the shaded region = 4·π/3 - (2·π + 9·√3)/6 = (2·π - 3·√3)/2

How Far Can A Snail Travel In One Hour

If a snail can travel over half an inch per minute, that means in one hour a snail can travel up to 40 inches. If you want to think about how far this is in feet, it means that snails move up to 3.5 feet per hour.

Consider the fact that the average human being can walk about a mile, or 5280 feet, in one hour.

This means that snails can take up to 1,500 days, or over 4 years, to travel just one mile.

Answer:

60 Adults and 55 Children

Step-by-step explanation:

We can work this out by writing two equations for the two unknowns and substituting in one for the other.

The two unknown variables we have here are the number of children and the number of adults. We can represent these unknown variables with the letters A (adults) and C (children).

If 115 people attended the concert, it means that:

A (no. adults) + C (no. children) = 115

So our first equation is A+C=115

If the total receipts was $260, it means that the total adult prices + total children prices = 260.

The total adult prices = the cost of each adult ticket (2.5) multiplied by the number of adults that attended. This means that the total number of adult receipts can be represented as: 2.5A

Similarly the total children receipts = the cost per child multiplied by the number of children, so the total children receipts can be represented as: 2C.

Since all receipts added up to 260, our second equation is:

2.5A + 2C = 260

Now we have our two equations, let's substitute one in for the other:

A + C = 115

If we rearrange the equation by subtracting C from both sides, we see that the number of adults is = 115 - C. (A=115-C)

This means we can substitute '115-C' for A in the other equation:

2.5(115-C) + 2C = 260

This is so we only have one unknown in our equation so we can solve for it.

Now we can just expand the brackets and solve!

287.5 - 2.5C + 2C = 260

287.5 - 0.5C = 260

Add C to both sides so it is positive (not necessary but helps keep more tidy and avoid sign errors), and subtract 260 from both sides:

287.5 - 0.5C + 0.5C - 260 = 260 - 260 + 0.5C

27.5 = 0.5C

27.5/0.5=0.5C/0.5

C = 55

There were 55 children!

Now we can just minus 55 from 115 to find the number of adults (our first equation) as there was a total of 115 people.

115 - 55 = 60

60 Adults and 55 Children went to the concert.

Answer:

A the answer is 24

Step-by-step explanation:

The values of ab, b - c, and c/d are 6, -1, and 4 respectively when a = 2, b = 3, c = 4 and d = 1.Using BODMAS rule, we can simplify the given expression.ab - c/d = 24

Given ab-c/d has a value of 24.Now, we have to find the value ofab, b - c, and c/d.Multiplying d on both sides, we getd(ab - c/d) = 24dab - c = 24d...(1)Now, we can find the value of ab, b - c, and c/d by substituting different values of a, b, c and d.Value of ab when a = 2, b = 3, c = 4 and d = 1ab = a * b = 2 * 3 = 6.

Value of b - c when a = 2, b = 3, c = 4 and d = 1b - c = 3 - 4 = -1Value of c/d when a = 2, b = 3, c = 4 and d = 1c/d = 4/1 = 4Putting these values in equation (1), we get6d - 4 = 24dSimplifying, we get-18d = -4d = 2/9

Answer:

I think the volume would be 9 times greater, and the surface area would be 3 times greater

Step-by-step explanation:

Answer:

the volume would be 9 times greater

the surface area would be 3 times greater

Step-by-step explanation:

Because if the shell grows from 1 inch diameter to 3 inch diameter, the surface area will increase 3x more. And the volume I assume is 3x greater because of the height is presumably 3 inches as well.

Answer:

15% of 25

Step-by-step explanation:

Given the following questions:

25% of 15
15% of 25

We find the answer by using the formula to calculate percentage for both questions.

Question one:
\(\frac{p\times n}{100}\)
\(\frac{25\times15}{100} =25\times15=375\div100=3.75\)
\(=3.75\)

25% of 15 is 3.75

Question two:
\(\frac{p\times n}{100}\)
\(\frac{15\times 25}{100}=15\times25=375\div100=3.75\)
\(=3.75\)

15% of 25 is 3.75

Finally:
\(3.75=3.75\)

\(15-3.75=11.25\)
\(25-3.75=21.25\)
\(11.25 < 21.25\)

Which means 15% of 25 is "greater than" 25% of 15.

Area of sector would be,

⇒ Area of sector = 102.6 feet squared

We have to given that,

Radius of circle = 14 ft

Angle θ = 60°

Now, We know that,

Area of sector = [θ/360]πr²

Where, r is radius of circle.

Hence, We can substitute all the values, we get;

Area of sector = [θ/360]πr²

Area of sector = [60/360](22/7)(14)²

Area of sector = [1/6][22/7][196]

Answer:

y = 15°

Step-by-step explanation:

Since ∠QOR and ∠UOT are vertical, they are congruent so ∠UOT = 5y. Since POS is a straight line (which has a measure of 180°) and ∠POS = ∠POU + ∠UOT + ∠TOS, we can write:

5y + 5y + 2y = 180

12y = 180

Step-by-step explanation:

The total cost of all the items he wants to buy with the applied discount and before tax is $9.9.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Bashir has a loyalty card good for a 10% discount at his local hardware store.

So, Each good he buys at (100 - 10)% = 90% of the value before tax.

He wants to buy some items that cost $11  before the discount and tax.

Therefore the amount he has to pay is,

Answer:

a) \(\Delta A \approx 26.389\,cm^{2}\), b) \(r_{A} \approx 0.019\), c) \(\delta = 1.9\,\%\)

Step-by-step explanation:

a) The area of the circular disk is modelled after this expression:

\(A = \pi \cdot r^{2}\)

The total differential is given by the following formula:

\(\Delta A = 2\pi r \cdot \Delta r\)

The maximum absolute error in the calculated area of the disk is:

\(\Delta A = 2\pi \cdot (21\,cm)\cdot (0.2\,cm)\)

\(\Delta A \approx 26.389\,cm^{2}\)

b) The relative error is given by:

\(r_{A} = \frac{\Delta A}{A}\)

\(r_{A} = \frac{26.389\,cm^{2}}{\pi \cdot (21\,cm)^{2}}\)

\(r_{A} \approx 0.019\)

c) The percentage error is:

\(\delta = r_{A}\times 100\,\%\)

\(\delta = 0.019 \times 100\,\%\)

\(\delta = 1.9\,\%\)

\(let \: x \: be \: the \: length \\ let \: y \: be \: the \: width\)
