Answer:
As functions of a true variable, exponential functions are uniquely characterized by the very fact that the expansion rate of such a function (that is, its derivative) is directly proportional to the value of the function.

Have a nice day hope this helps.
A 120 watt light-bulb is a 0.120 kilowatt light bulb.
In one hour, it uses 0.120 kilowatt-hour of energy.
If electrical energy costs $0.20 per kilowatt hour, then that light bulb costs
(0.120 kilowatt-hour / hour) x (0.20 dollar / kilowatt-hour) =
(0.120 x $0.20 / hour) =
$0.024 / hour = <span>2.4¢ per hour </span>
Answer:
When n=3 and x=−2 the answer is 11.
Step-by-step explanation:
Given:
Let p (n,x) be the function such that
![p (n,x) = n + 2x^{2}](https://tex.z-dn.net/?f=p%20%28n%2Cx%29%20%3D%20n%20%2B%202x%5E%7B2%7D)
To Find:
p (n,x) = p ( 3, -2) = ?
Solution:
![p (n,x) = n + 2x^{2}](https://tex.z-dn.net/?f=p%20%28n%2Cx%29%20%3D%20n%20%2B%202x%5E%7B2%7D)
Substituting n = 3 and x = -2 we get
![p (3, -2) = 3 + 2(-2)^{2}](https://tex.z-dn.net/?f=p%20%283%2C%20-2%29%20%3D%203%20%2B%202%28-2%29%5E%7B2%7D)
Negative square gives positive number therefore (-2)²=4
![p (3, -2) = 3 + 2\times 4](https://tex.z-dn.net/?f=p%20%283%2C%20-2%29%20%3D%203%20%2B%202%5Ctimes%204)
![p (3, -2) = 3 + 8\\p (3, -2) = 11](https://tex.z-dn.net/?f=p%20%283%2C%20-2%29%20%3D%203%20%2B%208%5C%5Cp%20%283%2C%20-2%29%20%3D%2011)
When n=3 and x=−2 the answer is 11.
Answer:
Step-by-step explanation:
<u>Perimeter is:</u>
- P = a + b + c
- P = 4x - 3 + x + 9 + 8 = 5x + 14
<u>Area is:</u>
- A = 1/2bh
- A = 1/2*8*3x = 12x
Correct choice is A
