The area for both polygons are:

Green polygon: 8

Red polyogon: 9

hope this helps

Step-by-step explanation:

AB = sqrt((4-0)^2 + (6-(-1))^2) = sqrt(16+49)=sqrt(65)

CD=sqrt((-8-(-4))^2 + (0-7)^2) = sqrt(49+16)=sqrt(65)

Therefore, sides AB and CD are congruent because they have the same measure.

BC = sqrt((4-(-4)^2 + (-1-0)^2) = sqrt(64+1)=sqrt(65)

AD=sqrt((0-(-8))^2 + (7-6)^2) = sqrt(64+1)=sqrt(65)

Therefore, sides BC and AD were congruent because they have the same measure.

This means ABCD is a parallelogram because there are two pairs of opposite congruent sides.

Now, notice that AB=BC, meaning sides AB and BC are congruent.

This means that parallelogram ABCD has one pair of consecutive congruent sides, and is thus a rhombus.

Step-by-step explanation:

we can use the pythagorean theorem so (15)²= (12)² + (x)²--> (15)²-(12)²=x²

take the square root of both sides ans x=9

note! this is a special type of triangle called a 3-4-5 special right triangle because all the sides when divided by a factor of 3 will simplify down to the sides 3-4-5 (only true when the hypotheneuse is the 5 because it's the longest side of a triangle)

Explanation:

Can we rotate the figure some angle smaller than 360 degrees and have it match up with its original image? The answer to that is "no". Any such rotation will change the image to something else. Therefore, this figure does not have any point symmetry (aka rotational symmetry).

Can we reflect one half of the figure over some line to get the other half? The answer here is also "no". The diagram has no reflectional symmetry either.

Plane symmetry is ruled out because that only applies to 3D settings.

If the question ask for an answer in terms of pi, this is your answer. If it doesn't, simplify it further to get:

You can round this however you like, but I would say either 3 significant figures, either 1 or 2 decimal places.

Answer/Step-by-step explanation:

The exponential function modeling the number of lions ⇒  the years passed since 2010 is appointed as

[tex]f(x)=2^1^+^2^x[/tex]

Well, If you have an question like what is exponential function?

Let's me tell you:

exponential functions which are expressed as some constant raised to the power of the argument called exponential function.

You might be asking how to find which function can model the given question..

[tex]\mathrm{Since \;2012 - 2010 = 2 \;and\; the\; number \;of\;lions = 32 =2^5}[/tex]

[tex]\mathrm{and \;2013 -2010 = 3\; and\; the\; number \;of\; lions\; =128 = 2^7}[/tex]

Hence, there is increment of 2 exponent as 1 year was changed.

Now, we have:

[tex]f(x)=2^2^x^+^a[/tex]

[tex]\mathrm{Thus,\; it\; increases \;every \;year \;by\; a \;ratio \;of \;2^(^2^)}[/tex]

[tex]\mathrm{Thus, \;in \;2011, \;it \;was \;2^(^5^) - 2^(^2^) = 2^(^3^)\; lions}[/tex]

[tex]\mathrm{In\; 2010, it\; was 2^(^3^) - 2^(^2^) = 2}[/tex]

Since Lions were introduced in the park in 2010, using f(x), it means;

[tex]x = 0, f(x) = 2[/tex]

[tex]x = 1, f(x) = 2^(^3^)[/tex]

[tex]x = 2, f(x) = 2^(^5^)[/tex]

[tex]x = 3, f(x) = 2^(^7^)[/tex]

Let's use the generic formula: y = ab^(x)

At x = 0 and y = 2, we have:

[tex]2 = a * b^(^0^)[/tex]

Thus,a = 2

At x = 1, y = 2^3

b = 8/2

b = 4

So the exponential equation is;

[tex]y = 2(4^(^x^))[/tex]

Answer:

6:41

Step-by-step explanation:

We know that the number of students going on the field trip is 6.

To find the total number of students, add the number of students going on the trip and the number of students staying at the school: 6 + 35 = 41

So the ratio of the number of students going on the field trip to the total number of students is 6:41

Answer: Train A weighs 418 tons and Train B weighs 61 tons

Step-by-step explanation:

Let a represent the weight of Train A, and let b represent the weight of Train B.

We can set up a system of equations.

a + b = 479

a - b = 357 ( as we are given that a is heavier than b )

We can add the two equations:

a + b + a - b = 479 + 357

Combine like terms (which cancels out the b):

2a = 836

Divide both sides by 2:

a = 418

We can plug this back into the first equation:

418 + b = 479

Subtract 418 from both sides:

b = 61

The approximate lateral area of the circular cone with has the base diameter 18 in and height 40 in long is 1,159 square inches

Lateral area of the cone is the area bounded by the surface of the cone, and this Lateral area of the cone can be found out using the following formula.

[tex]A=\pi r\sqrt{h^2+r^2}[/tex]

here. (h) is the height of the cone and (r) is the radius of the cone.

A cone has a circular base with a diameter of 18 inches. The height of the cone is 40 inches.

Put these values in the above formula as,

[tex]A=(3.14) (9)\sqrt{40^2+9^2}\\A\approx1159\rm \; in^2[/tex]

Hence, the approximate lateral area of the circular cone with has the base diameter 18 in and height 40 in long is 1,159 square inches
