what is the area of the regular polygon shown below?

The Area of Piece of Land is  = 150 +[tex]24\sqrt{11}[/tex]  squared yards

The area of a trapezium can be calculated using the lengths of two of its parallel sides and the distance (height) between them.

As the yard is in shape of Trapezium.

We have to find the area of trapezium.

Area of piece of property = Area of Triangle +  Area of rectangle + Area of Triangle

Area of Triangle I,

base = [tex]\sqrt{(13)^{2}{-(12)^{2}}[/tex] = [tex]\sqrt{169-144}[/tex]= 5yds

Area = [tex]\frac{1}{2}*b*h[/tex]

        =0.5 x 5 x 12

       = 30 squared yds

Area of rectangle = length x breadth

                             = 10 x 12

                             = 120 squared yds

Area if Triangle II, base = [tex]\sqrt{(15)^{2}{-(7)^{2}}[/tex]= [tex]\sqrt{225-49}[/tex]= [tex]4\sqrt{11}[/tex]

Area= [tex]\frac{1}{2}*b*h[/tex]

        =0.5 x [tex]4\sqrt{11}[/tex]  x 12

        = [tex]24\sqrt{11}[/tex] squared yds

Area of piece of land = 30 + 120 + [tex]24\sqrt{11}[/tex]

                                    = 150 +[tex]24\sqrt{11}[/tex] squared yards

Hence, the area of piece of land= 150 +[tex]24\sqrt{11}[/tex]  squared yards

Answer:

p(x) = 500(1.02)^x

Step-by-step explanation:

I took the test and got a 100.

The exponential function is p(x) = 500(1.02)×, option (D) is correct.

It is defined as the function that rapidly increases and the value of the exponential function is always positive. It denotes with exponent [tex]y = a^x[/tex]

where a is a constant and a>1

We have the functions given in the options:

As we know the standard form of the exponential function is:

f(x) = a(b)×

The exponential function will increase or decrease exponentially.

From the option:

p(x) = 500(1.02)×

p(x) is an exponential function.

Thus, the exponential function is p(x) = 500(1.02)×, option (D) is correct.

Answer:

  (a)  46°

  (b)  86°

Step-by-step explanation:

When the secants cross externally (figure a), the angle where they cross is half the difference of the subtended arcs.

When they cross internally (figure b), the angle is half the sum of the subtended arcs.

Answer:

$172,984.44

Step-by-step explanation:

We can use the formula

[tex]A = P(1 + \frac{r}{n})^{nt}[/tex] to compute the final amount

Here P is the principal amount, the original deposit = $25,000

r is the annual interest rate = 6.5% = 0.065 in decimal

n is the number of times the compounding takes place. Here it is quarterly so it is 4 times a year

t is the number of time periods ie 30 years

A is the accrued amount ie principal + interest

Computing different components,

[tex]nt = 4 \times 30 = 120[/tex]

[tex]r/n = 0.065/4 = .01625[/tex]

[tex]1 + r/n = 1.01625[/tex]

[tex](1 + r/n)^{nt} = 1.01625^{120}[/tex]

Therefore

[tex]A = 25000 \times 1.0625^{120} = 172,984.44[/tex]

Answer:

585 m^2.

Step-by-step explanation:

Surface area = area of base + 4 * area of a triangular side

= 13^2 + 4 * 1/2 * 13 * 16

= 169 + 26 * 16

= 585

Answer:

585 m²

Step-by-step explanation:

The surface area of the given pyramid is made up of 4 congruent triangles and a square base.

Area of a triangle = 1/2 × base × height

                             = 1/2 × 13 × 16

                             = 104 m²

Area of a square = (base edge)²

                            = 13²

                            = 169 m²

Total Surface Area = area of 4 triangles + area of base square

                               = (4 × 104) + 169

                               = 416 + 169

                               = 585 m²

Answer:

128

Step-by-step explanation:

There are 2 lengths, 16 x 2 = 32. 48 - 32 = 16. 16 divded by 2 equals 8. 8 x 16 = 128.

Answer:

  261 in²

Step-by-step explanation:

The surface area of a square pyramid can be found from the formula ...

  A = s(s +2h)

where s is the side length of the base and h is the slant height of a face.

__

For s = 9 in, and h = 10 in, the surface area is ...

  A = (9 in)(9 in +2×10 in) = (9·29) in² = 261 in²

The surface area of the square pyramid is 261 square inches.

Answer:

0.0102 g

Step-by-step explanation: A common formula for determining the amount of sample remaining in terms of its half-life is

where

t = 50 000 yr

      Calculate n

n = 50 000/5730

n = 8.726

N₀ = 4.30 g                       Calculate N

N = 4.30 × 2.36 × 10⁻³

N₀ = 0.0102 g please mark me brainliest

Answer:

  0.0102 g

Step-by-step explanation:

You want to know the amount of C-14 remaining in a tree branch after 50,000 years if it originally had 4.30 grams, and C-14 has a half-life of 5730 years.

The number of grams (N) remaining is given by the formula ...

  N = N₀(1/2)^(t/5370)

where t is the number of years and N₀ is the initial amount of C-14.

The amount of C-14 remaining in the tree branch will be ...

  N = 4.30×(1/2)^(50000/5730) ≈ 0.010154 . . . . grams

This can be rounded several ways, depending on the criterion you choose.

The initial value 4.30 has 3 significant figures, so this could be rounded to 3 significant figures as 0.0102 g. This is the value we show at the top of this answer.

The initial value is accurate to a hundredth of a gram, so this could be rounded to a hundredth of a gram as 0.01 g.

The value 50,000 years has 1 significant digit, so we could round this to 1 significant digit as 0.01 g.

__

Additional comment

The problem statement gives the initial amount twice, once with 3 significant figures, and once with only 2 significant figures. If the answer is rounded to 2 significant figures, it would be 0.010 g.

There does not appear to be any justification for an answer of 0.0100 grams.

2. Basketball balls

3. Volleyball balls

4. Tennis balls

Step-by-step explanation:

The unit circle is a circle in the form of

[tex] {x}^{2} + {y}^{2} = 1[/tex]

while x = cos t

y= sin t

, where t is an angle

So we plug in -1/7, for x to find y

[tex]( \frac{ - 1}{7} ) {}^{2} + {y}^{2} = 1[/tex]

[tex] {y}^{2} = \frac{49}{49} - \frac{1}{49} [/tex]

[tex]y = \frac{4 \sqrt{3} }{7} [/tex]

If the point is in the 2nd quadrant, your value of y is positive

If it in the third quadrant, the y value is negative

Answer:

Average per floor = 162 dollars.

Step-by-step explanation:

Remark

First find the number of floors

Then make a total   income received from those floors.

Then divide the total income by the number of floors, to get the average

Number of floors

Total number of floors = 6 + 2 + 1 = 9 floors

Total income

Total income = cost per floor * the number of floors.

Total income

6 * 140 =  840

2 * 220 = 440

1 * 178   = 178

Total    = 1458

Average income / Floor

Average income / Floor = Total amount / number of floors

Average Income / Floor = 1458 / 9 =  162

Answer:

a) 80
b) 56

Step-by-step explanation:

a) Calculate the volume of the the cup using volume of cylinder equation: [tex]V = \pi r^{2} h[/tex]

Where V = Volume, r=radius, and h=height. Your answer should be in cubic inches ([tex]in^3[/tex]).
You're given diameter, so use equation [tex]d/2 = r[/tex] to find radius.
Substituting these equations will give you: [tex]V = \pi (d/2)^2 h[/tex]
However, the given volume of the sink is 3000[tex]\pi[/tex], meaning that you should modify your results to match this value. Do not substitute [tex]\pi[/tex] for 3.14..., leave it as a symbolic value. Your final V of the cup should = 37.5 [tex]\pi[/tex]
Divide the volume of the sink by the volume of the cup. This number will be the amount of cups needed to empty it. In equation form:
[tex]Vsink / V cup =[/tex] # of cups.
Note the the [tex]\pi[/tex] will cancel each other out, so there's not need to factor that in.
b) Repeat the steps above with the new d (diameter) value.

Option D) also does not return an integer.

[tex]{\: \: \: \: \: \: \: \: \: \: \: \: \: \sf{44 \div 3 = 14.66}}[/tex]

And lastly option E) does not result in an integer so the only one that results in an integer is option C) and that is the 42nd answer.
