A binomial is going to have two terms. =)
First of all, let's study each function:
Function A) 
This is a
quadratic function. This type of function is a second-degree polynomial function.
Function B) 
<span>
</span>
This is an
exponential function. This type of function is a non-algebraic function. It's also called <span>transcendental function.
</span>
Function C)<span>

</span>
It's a
straight line with slope equal to 100 and without y-intercept.
Function D)
<span>
It's a
cubic function. It's a third</span>-degree polynomial function.
So from the figure it is obvious that
the function that grows at the fastest rate is the exponential function B). In fact, an exponential function always grows more quickly than a polynomial function.
Answer:

Step-by-step explanation:)
The equation 9cos(sin¯¹(x)) = √(81 – 81x²) is true since L.H.S = R.H.S
To answer the question, we need to know what an equation is
<h3>What is an equation?</h3>
An equation is a mathematical expression that show the relationship between two variables.
Given 9cos(sin¯¹(x)) = √(81 – 81x²), we need to show L.H.S = R.H.S
So, L.H.S = 9cos(sin¯¹(x))
= 9[√{1 - sin²(sin¯¹(x)}] (Since sin²y + cos²y = 1 ⇒ cosy = √[1 - sin²y])
9[√{1 - sin²(sin¯¹(x)}] = √9² × √{1 - sin²(sin¯¹(x)}]
= √[9² × {1 - sin²(sin¯¹(x)}]
= √[81 × {1 - sin²(sin¯¹(x)}]
= √[81 × {1 - x²}] (since sin²(sin¯¹(x) = [sin(sin¯¹(x)]² = x²)
= √(81 – 81x²)
= R.H.S
So, the equation 9cos(sin¯¹(x)) = √(81 – 81x²) is true since L.H.S = R.H.S

Using I = PRT
$2500 - $2000 = $2000 × 0.04 × t
$500 = 80t
t = $500 ÷ 80
t = 6.25 years
so the answer is 6
