Keep your mom, you only have one. But anyway;
Use the Pythagorean Theorem: A^2 + B^2 = C^2
12^2 + 21^2 = C^2
144 + 441 = C^2
585 = C^2
square root of 585 = approximately 24.2
Answer:
Answers are below
Step-by-step explanation:
Hour 0 1 bacterium
Hour 1 3 bacterium
Hour 2 9 bacterium
Hour 3 27 bacterium
Hour 4 81 bacterium
Hour 5 243 bacterium
Hour 6 729 bacterium
After 24 hours, the number of the bacterium will reach 282,429,536,481.
B) This table represents exponential growth because of the number of bacterium always being multiplied by 3.
C) The reason that any number to the zero power is one is that any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, 1.
D) Y = 1 + 3 to the power of x
E) The rule would change by having all of the numbers multiplied by 100 since there is 100 bacterium at Hour 0.
The approximate area of the decagon with a side of 8cm comes to be 492.40 cm².
The side of the regular decagon = 8cm
<h3>What is a regular decagon?</h3>
A regular decagon is a polygon with 10 sides that are equal to each other.
The area of a regular decagon with side a is:
![A=\frac{5}{2} a^{2} \sqrt{5+2\sqrt{5} }](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B5%7D%7B2%7D%20a%5E%7B2%7D%20%5Csqrt%7B5%2B2%5Csqrt%7B5%7D%20%7D)
So, the area A of the regular decagon with a side of 8cm:
![A=\frac{5}{2} 8^{2} \sqrt{5+2\sqrt{5} }](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B5%7D%7B2%7D%208%5E%7B2%7D%20%5Csqrt%7B5%2B2%5Csqrt%7B5%7D%20%7D)
![A=160\sqrt{5+2\sqrt{5} }](https://tex.z-dn.net/?f=A%3D160%5Csqrt%7B5%2B2%5Csqrt%7B5%7D%20%7D)
A=492.40 cm²
Therefore, the approximate area of the decagon is 492.40 cm².

The word degree is just another word for exponent.
23x^4 is the correct way to write the monomial.
What exponent do you see?
You see 4, right?
So, the degree is 4.
