The values of x are x₁ ≈ 4.8 and x₂ ≈ - 0.8.
<h3>What is the quadratic equation behind two circular sections of equal area?</h3>
Herein we have two <em>circular</em> sections of equal area, whose expressions are described by the following geometric equations:
Semicircle
A = 0.5π · x² (1)
Half Semicircle
A = 0.25π · (x + 2)² (2)
By equalizing (1) and (2):
0.5π · x² = 0.25π · (x + 2)²
2 · x² = (x + 2)²
2 · x² = x² + 4 · x + 4
x² - 4 · x - 4 = 0
x² - 4 · x + 4 = 8
(x - 2)² = 8
x - 2 = ±√8
x = 2 ± √8
x = 2 ± 2√2
x = 2 · (1 ± √2)
x = 2 · (1 ± 1.41)
x₁ = 2 · 2.41 ∨ x₂ = 2 · (- 0.41)
x₁ = 4.82 ∨ x₂ = - 0.82
The values of x are x₁ ≈ 4.8 and x₂ ≈ - 0.8.

X/13 2/7
X=2/7*(13)
X=26/7 Final Answer
Hey there!!!
Remember :
===> n⁻ˣ is equal to 1 / nˣ
In the question, it is stated n as 6 and x is 3
====> 6⁻³
... 1 / 6³
= 1 / 216
Hope my answer helps!
Answer:
10+8+6=24 the ratio of taking the biographies to the science books are: 4:3
Step-by-step explanation:
That is the answer because 10+8+6= total 24 books
ratio of biographies= 24:8=3:1
ratio of science fiction= 24:6= 4:1
hence according axiom 1 ab × Ac= aa × BC
3:1×4:1= 4:3
