Answer:
A $0.02
Step-by-step explanation:
Let's solve how much does it cost to have a bulb on for an hour. ⇒ 120 watt = 0.1 kilowatt per hour which costs 0.20 per kilowatt per ⇒ 0.1 kilowatt per hour* 0.20 = 0.02 dollars in an hour.
Answer:
18(2x - 3)
Step-by-step explanation:
Hey there! :)
In order to factor 36x - 54, you must find the common factors of it.
So, we must ask ourselves : what number goes into BOTH 36x & -54?
Our answer is going to be 18.
So, let's ask ourselves a couple more questions :
How many times does 18 go into 36x?
&
How many times does 18 go into -54?
36x ÷ 18 = 2x
-54 ÷ 18 = -3
Therefore, 18 goes into 36x 2 times while 18 goes into -54 3 times.
So now that we know that, simply take 18 out like so :
18(2x - 3)
This is our answer because when multiplied by 2x, 18 turns into 36x. In addition, when multiplied by 18, -3 turns into -54.
Hope I helped! :)
The derivative of the given function is f'(x) = k f(x) where 
.
<h3>What is the derivative of a function?</h3>
Let f be a function defined on a neighborhood of a real number a. Then f is said to be differentiable or derivable at 'a' if 
exists finitely. The limit is called the derivative or differential coefficient of f at 'a'. It is denoted by f'(a).
If f is differentiable at 'a', then
<h3>Calculation:</h3>
The given properties are:
(i) f(x + y) = f(x)f(y) for all real numbers x and y.
(ii) 
= k; where k is a nonzero real number.
Then, the derivative of the function f(x) is,
f'(x) = 
From property (i), f(x + h) = f(x)f(h)
On substituting,
f'(x) = 
= ![\lim_{h \to 0} \frac{f(x)[f(h) - 1]}{h}](https://tex.z-dn.net/?f=%5Clim_%7Bh%20%5Cto%200%7D%20%5Cfrac%7Bf%28x%29%5Bf%28h%29%20-%201%5D%7D%7Bh%7D)
From property (ii), = k;
f'(x) =
= f(x).
= f(x). k
= kf(x)
Therefore, f'(x) = k f(x); where f'(x) exists for all real numbers of x.

The answer is 14.4 because if the last number is 5 or higher you round up if not you round down. Then, you should get 14.40 but, the 0 isn't necessary so the answer is 14.4.
