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

Hey there!

ORIGINAL EQUATION:
0.75(2 + 6 x 4 - 2 × 7 - 2)

WORKING WITHIN the PARENTHESES:
2 + 6 x 4 - 2 × 7 - 2

= 2 + 24 - 2 × 7 - 2

= 26 - 2 × 7 - 2

= 26 - 14 - 2

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]

Answer:

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)

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.

Step-by-step explanation:

The number of pizza pieces left is (x + 4) / 4. Option c

Let's assume the total number of pizza pieces is represented by 'x'.

Kevin takes 1/4 of the total pieces, which is (1/4) * x = x/4.

Keith takes one piece less than twice the number of pieces Kevin took, which is 2 * (x/4) - 1 = (2x/4) - 1 = x/2 - 1.

To calculate the number of pizza pieces left, we need to subtract the sum of Kevin's and Keith's pieces from the total number of pieces (x):

Leftover pieces = Total pieces - (Kevin's pieces + Keith's pieces)

= x - (x/4 + x/2 - 1)

= x - (3x/4 - 1)

= x - 3x/4 + 1

= (4x - 3x + 4) / 4

= (x + 4) / 4

Therefore, the number of pizza pieces left is (x + 4) / 4.

The correct option among the given choices would be (c) 1/2x + 1.

Answer:

[tex]k = \frac{322}{27} [/tex]

Step-by-step explanation:

x + 3 = 0 → x = - 3

25 + 4(-3)⁴ + k(-3)³ + (-3) - 11 = 13

25 + 324 - 27k - 3 - 11 = 13

349 - 27k - 14 = 13

349 - 14 - 13 = 27k

349 - 27 = 27k

322 = 27k

k = 322/27
