Answer:

3077.68

Step-by-step explanation:

the Area of the regular decagon is 3077.68

The area of the decagon with side length of 20 units is -

A = 1000√(5 + 2√5) square units.

Area is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write area -

V = ∫∫F(x, y) dx dy

Given is a regular decagon with length of each side is 20 units

The area of the regular decagon is -

A = (5/2)a²√(5 + 2√5)

We have {a} = 20. So, we can write that -

A = (5/2)(20)²√(5 + 2√5)

A = (5/2) x 400 x √(5 + 2√5)

A = 5 x 200 x √(5 + 2√5)

A = 1000√(5 + 2√5)

Therefore, the area of the decagon with side length of 20 units is -

A = 1000√(5 + 2√5) square units.

Answer:

B. 35 Square Miles

Step-by-step explanation:

Answer:

The answer is "It must be shown that both [tex]j(k(x))\ and \ k(j(x))=x[/tex]"

Step-by-step explanation:

Given:

[tex]j(x) = 11.6 e^{x} \\\\k(x) =\ln\frac{x}{11.6}[/tex]

To show that both are equal functions, and  show that both[tex]j(k(x))\ and\ k(j(x)) =x,[/tex]

For [tex]j(k(x));[/tex]  

[tex]j(k(x)) = j[(\ln \frac{x}{11.6})]\\\\j[(\ln (\frac{x}{11.6})] = 11.6e^{\ln (\frac{x}{11.6})}\\\\j[(\ln \frac{x}{11.6})] = 11.6(\frac{x}{11.6})\\\\[/tex](The natural logarithm is canceled by exponential function)  

[tex]j[(\ln \frac{x}{11.6})] = 11.6 \times\frac{x}{11.6}\\\\j[(\ln \frac{x}{11.6})] = x\\\\j[k(x)] = x\\\\for\ \ k[j(x)]:\\\\k[j(x)] = k[11.6e^x]\\\\k[11.6e^x] = \ln (\frac{11.6e^x}{11.6})\\\\k[11.6e^x] = \ln(e^x)[/tex]

Its natural logarithm leaving x will nullify expanding universe.

[tex]k[11.6e^x] = x\\\\k[j(x)] = x[/tex]

In the question, it is seen that[tex]j[k(x)] = k[j(x)] = x[/tex], shows that the functions [tex]j(x) = 11.6 e^{x} \ and \ k(x) = \ln \frac{x}{11.6}[/tex] is inverse functions.

6f^3−8f^3−15f

=(3f−4)(2f2−5)

Answer:

(3f−4)(2f^2−5)

Find the group you want to factor, such as in the first parenthesis, you remove 3f from the whole equation, and end up with 3f-4. You take the end value, and group it with -5. You will then end up with 2f^2 -5.

Answer:

y = 3x - 9

Step-by-step explanation:

Let's start by finding the slope of the line:

The formula for slope is [tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex].

Plug in the numbers and solve:

[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]

[tex]m = \frac{-3 - (-6)}{2 - 1}[/tex]

[tex]m = \frac{3}{1}[/tex]

[tex]m = 3[/tex]

The slope of the line is 3.

The slope intercept form of a line is y = mx + b, where m is the slope and b is the y coordinate of the y-intercept.

Plugging in the number we got for the slope, the equation becomes:

y = 3x + b

Let's solve for b by plugging in an ordered pair for y and x:

y = 3x + b

-3 = 3(2) + b

-3 = 6 + b

b = -9

The y-coordinate of the line is (0, -9).

Now, plugging in the number into our equation, we get:

y = 3x + (-9)

y = 3x - 9

And that's the equation of the line!

Answer:

Answer: The answer is 280 ft.

Step-by-step explanation:

divide the green area into a triangle and a rectangle so it's easier to calculate. Then find the area of the rectangle by multiplying 14 times 16. That should get you 224. Then, find the area of the tringle by multiplying 14 times 18, times 1/2. That will get you 56. If you add 56 to 224, that gets you 280.

The median is 3.5

y = 7/5x - 21/5

Step-by-step explanation:

points to use to find slope:  (3,0) and (8,7)

slope = 7-0 / 8-3

slope = 7/5

find y-intercept (or 'b')

0 = 3(7/5) + b

0 = 21/5 + b

-21/5 = b

b = -4 1/5

Answer:

B. A dilation with a scale factor of 0.5

Step-by-step explanation:

A. is wrong because it is congruent transformation because reflections keep the angles and side lengths of the figure the same.

B. is right because it is NOT congruent because a dilation of any scale factor other than 1 results in a similar figure, because the side lengths are proprtional but not equivalent

C.  is wrong because translations keep the angles and side lengths of the figure the same.

D. is wrong because a scale factor of 1 changes nothing about the figure.

Answer:

[tex]P(t)=2500(1.04)^t[/tex]

Step-by-step explanation:

None of your proposed answers has an exponent t.

Here's the logic behind the answer:

Year 0: pop. = 2500

Year 1:  pop. = 2500(1.04)  That is 104% of the previous year's pop.

Year 2: pop. = 2500(1.04)(1.04) = 2500(1.04)^2

Year 3: pop. = 2500(1.04)^2 x (1.04) = 2500(1.04)^3

See the pattern?  The exponent matches the year number.
