The correct answer for the question that is being presented above is this one: "(1) <span>For all real numbers a and b, a + b = b+ a; </span>(2) For all real numbers a and b, ab = ba; (3) <span>For all real numbers a, b and c, (a + b) + c = a + (b + c); (4) </span><span>For all real numbers a, b and c, a (b + c) = ab + ac." </span>
Answer:
The statement provided is True.
Step-by-step explanation:
The exponential function representing growth is given as follows:
Here,
<em>y</em> = final value
<em>y</em>₀ = initial value
<em>k</em> = growth rate
<em>t</em> = time passed
As the function 
is increasing, then the exponential function representing growth is also increasing.
Thus, the statement provided is True.
We have the following function:
C (t) = 6t - 180
Clearing t we have:
6t = c + 180
t = c / 6 + 180/6
Rewriting:
t (c) = (c + 180) / 6
Answer:
The inverse function for this case is given by:
t (c) = (c + 180) / 6
option A
