<u>Answer:</u>
when electric chargers build up on objects is called Static Electricity
<u>Explanation:</u>
When electric charges are built up on objects which can happen due to rubbing or pulling apart of some materials, we get positive charges (+) get collected on surface of one material and negative charges (-) on another. These objects stay charged for some time till they aren't transferred elsewhere through interaction.
This electrically charged surfaces creates a shock type effect when touched. This charging of surfaces of objects due to accumulation of electrons or protons is known as static electricity or static discharge.
Answer:
Step-by-step explanation:
<h3>Given</h3>
- f(n) = n ^ 4 + 5n ^ 3 + 2n ^ 2 - 5n + 13
<h3>To find </h3>
<h3>Solution</h3>
<u>Substituting n with -2</u>
- f(-2) =
- (-2)^4 + 5(-2)^3 + 2(-2)^2 - 5(-2) + 13 =
- 16 - 40 + 8 + 10 + 13 =
- 7
Answer:
$10452958
Step-by-step explanation:
Initial profit = $11900848
Fall rate= $48263 per year
Equation:
- P(x)= 11900848 - (x-1990)*48263,
where P(x)= profit at year of x, and 1990<x<2020
- P(2020)= 11900848- 30*48263= $10452958
Answer:The answer is c
Step-by-step explanation:
Multiply both side is the equation by -1.
Sum the equations vertically to eliminate at least one variable
Divide both sides of the equation by 3
Substitute the given value of y into the equation 2x+3y=8
and then solve for x
Use hypotenuse leg theorem.
