Regular polygon area = n*side^2 / (4 * tan (180/n))
where "n" is number of sides
The formula is dependent on the side^2 term,
So, if we have an octagon that has sides 4 times as large, that means the area will be sixteen times larger.
side^2 = 4^2 = 16
So we multiply 25 cm^2 by 16 and we get
400 square centimeters.

What parent function has the following applications: profit, gravity, and calculating area?
Ronch [10]

Answer:

Suppose that you have a square of side length x, the area of this square will be:

A = x^2.

Now, by dynamics, we know that the position of an object that is falling down from a height H, can be written as:

H(t) = (-g/2)*t^2 + H.

We can see a pattern, x^2 is used in both.

Now, profit can be also modeled with quadratic equations, where our objective is to find the maximum of the quadratic (so we can have the maximum profit)

Then the parent function that is useful for gravity, calculating area and profit is the quadratic function:

f(x) = x^2

Solve x3 = 1 over 8.<br><br> 1 over 2<br> ±1 over 2<br> 1 over 4<br> ±1 over 4
olganol [36]
The answer is 1/2. The reasoning is 1/2 x 1/2=1/4 1/4 x 1/2=1/8 fractions multiply on numerator and denominator then simplify

I can solve it, but I am struggling on explaining how I solved it. Here's the answer.

x+y=15

5x+10y=100

x=10 and y=5

10+5=15

5(10)+10(5)=100
50+50=100
100=100
