DE=DFSo triangle is isosceles
<E=<F=55°Find the ‘exact’ perimeter of each triangle
Answer:
[tex]\huge\boxed{\sf 8 + 4\sqrt{2} \ cm }[/tex]
Step-by-step explanation:
[tex]\theta = 45 \textdegree[/tex]
opposite = 4 cm
Using tan first to find the adjacent side:
[tex]\displaystyle tan \theta = \frac{opposite}{adjacent} \\\\tan \ 45 = \frac{4}{adjacent}\\\\1 = \frac{4}{adjacent} \\\\Multiply \ 'adjacent' \ to \ both \ sides\\\\adjacent = 4 \ cm[/tex]
Finding Hypotenuse now by using Pythagorean theorem:
[tex](Hyp)^2 = (base)^2 + (perp)^2[/tex]
where base = 4, hyp = 4
(Hyp)² = (4)² + (4)²
(Hyp)² = 16 + 16
(Hyp)² = 32
Take sqrt on both sides
[tex]Hyp = 4\sqrt{2}[/tex] cm
Exact perimeter of triangle:
= base + perpendicular + hypotenuse
= 4 + 4 + 4√2
= [tex]8 + 4\sqrt{2}[/tex] cm
[tex]\rule[225]{225}{2}[/tex]
The formula for area of a circle is pi*r^2. If the radius is 20, what is the area?
Answer:
area of circle = πr^2
just substitute 20 for r:
π(20)^2
= 400π
If the question ask for an answer in terms of pi, this is your answer. If it doesn't, simplify it further to get:
= 1256.637061 (m/cm)^2
You can round this however you like, but I would say either 3 significant figures, either 1 or 2 decimal places.

Choose the kinds of symmetry the following figure has: point, line, plane, or none.
none
plane
point
line
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.

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]

) 6 students are going on a field trip and 35 students are staying at school. What is the ratio of
the number of students who are going on the field trip to the total number of students?
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
