The growth of a population is not linear, it's exponential.
31.
Exponential growth > polynomial, so .

The point of symmetry of a quadratic equation is at its vertice:
The line is x= 3.
The age of Kwaku is 8 years old , Esi is 13 years old and Kojo is 26 years old.
<h3>What is an Equation ?</h3>
An equation is a statement that contains algebraic expressions equated by an equal sign with constants or other variables.
Let the age of Kwaku is x
Let the age of Esi is y
From the given data
The age of Kojo is 2y
y = x +5
Sum of their age = 47
2y = 2x +10
therefore the equation formed is
x + y +2y = 47
x + x+5 + 2x +10 = 47
4x +15 = 47
4x = 32
x = 8
y = 13
2y = 26
Therefore Kwaku is 8 years old , Esi is 13 years old and Kojo is 26 years old.

Answer: 13
Step-by-step explanation:
To get F(x), apply BODMAS; multiply first, then add, finally, subtract
F(x) = 2x4 + 3x3 – 2x2
= 8 + 9 - 4
17-4
f(×)= 13
Area of a square of side x = x^2.
If this area is 100 m^2, 10^2 m^2. The length of one side of this square
is the sqrt of 10^2 m^2, or x=10m.
