Since the hexagon is regular, we know that all of the side lengths are equal. We can find the length of the sides by solving for [tex]l[/tex] in the formula for the area of a hexagon:
[tex]A = \frac{3\sqrt{3}}{2}l^2\\384\sqrt{3} = \frac{3\sqrt{3}}{2}l^2\\384 = \frac{3}{2}l^2\\256 = l^2\\16 = l[/tex]
Now that we have the side length, we can find the area of the square:
[tex]A = l^2\\A = 16^2\\A = 256[/tex]

How do negative exponents impact the value of a number?
Answers
Answer:
A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ. For example, 2⁻⁴ = 1 / (2⁴) = 1/16.

Answers
A strategy which would produce a new confidence interval with an increased margin of error is to: A. use a 98% confidence level.
What is a confidence interval?A confidence interval simply refers to a range of estimated values which defines the probability that a population parameter will lie within it.
How to calculate the margin of error?Mathematically, a margin of error is calculated by using this formula:
[tex]MOE_{\gamma}=Z_{\gamma} \times \sqrt{\frac{\sigma^2}{n} }[/tex]
From the above formula, we can deduce that the margin of error is directly proportional to the critical value and inversely proportional to the square root of sample size.
This ultimately implies that, increasing the confidence level from 95% to 98% would increase the critical value and by extension the margin of error and vice-versa.

How many different meals are possible?
Answers
3421880 number of the different meals are possible.
What is the combination?The arrangement of the different things or numbers in the number of the ways is called as the combination.
It is given that:-
Number of appetizers is 7, the number of entres is 10, and that there's 4 choices of desserts.
So let's take each course by itself. You can choose 1 of 7 appetizers. So we have n = 7 After that, you chose an entre,
so the number of possible meals to this point is
n = 7 x 10 = 70
Finally, you finish off with a dessert, so the number of meals is:
n = 70 x 4 = 280
Therefore the number of possible meals you can have is 280. Note: If the values of 77, 1010 and 44 aren't errors, but are actually correct, then the number of meals is
n = 77 x 1010 x 44 = 3421880
Therefore 3421880 different meals are possible.

2. What is the new correction equation using the Equal Values Method for the following system below?
y=2x+1
y = 6-3x
Answers
Answer:
new equation: 2x +1 = 6 -3x
solution: (x, y) = (1, 3)
Step-by-step explanation:
The Equal Values Method of solving a system of equations has you equate the two expressions that are equal to the same variable or expression. Here, we have two expressions that are equal to y.
equationThe next step is to set them equal to each other:
2x +1 = 6 -3x
__
solutionThis equation can be solved by adding 3x -1 to both sides to get ...
5x = 5
Then dividing both sides by 5 gives ...
x = 1
Substituting into either expression for y gives its value:
y = 2x +1 = 2(1) +1 = 3
The solution to the system is (x, y) = (1, 3).
A motor boat traveled 18 miles down a river in 2 hours but took 4.5 hours to return upstream. Find the rate of the motor boat in still water and the rate of the current.
Answers
b = speed of the boat in still water
c = speed of the current
when going Upstream, the boat is not really going "b" fast, is really going slower, is going "b - c", because the current is subtracting speed from it, likewise, when going Downstream the boat is not going "b" fast, is really going faster, is going "b + c", because the current is adding its speed to it.
now, going either way the boat travelled the same 18 miles.

Simplify the following fraction WITHOUT USING A CALCULATOR tan 45°.sin 30-cot45°
Answers
Answer:
tan 45°.sin 30° - cot45° = −(1÷2) = −0.5Step-by-step explanation:
45° Corresponds to (π÷4) which is a remarkable measure
We are all supposed to learn by heart the values of it’s ‘sin’ , ‘cos’ , ‘tan’ and ‘cot’ .
the same apply to 30° (corresponds to (π÷6))
……………………………………………………………
So without a calculator:
tan 45° = 1
cot 45° = 1
sin 30° = 1/2
therefore ,
tan 45°.sin 30° - cot45° = 1 × (1÷2) − 1 = (1÷2) − 1 = −(1÷2) = −0.5
