Answer:
When beginning to explore the world of electricity and electronics, it is vital to start by understanding the basics of voltage, current, and resistance.
Step-by-step explanation:
These are the three basic building blocks required to manipulate and utilize electricity. At first, these concepts can be difficult to understand because we cannot \"see\" them. One cannot see with the naked eye the energy flowing through a wire or the voltage of a battery sitting on a table.
Step-by-step explanation:
f(x)=x²-1, f(x-1)=(x-1)²-1
=(x-1)(x-1)-1
=(x²-x-x+1)-1
=x²-2x+1-1
=x²-2x=0
x²=2x
x=2
Answer:
The relationship between the lengths of the sides of the triangle is that they all follow the Pythagorean Theorem (at least I'm pretty sure that's the answer.
Step-by-step explanation:
If you plug in the smaller sides like 9^2+40^2 which equals to 1681. Then you square 1681, you'll get 41 as your hypotenuse. The sides of triangle provided above your question, should follow the formula given to you which is c^2=a^2+b^2. Just to be safe, you can check if all of the triangle sides actually are true for the Pythagorean theorem.
Answer:
4f-5+6g
Step-by-step explanation:
Standard Form:4f-5+6g
(4f - 3 + 2g) - (-4g + 2) REMOVE PARENTHESIS
4f-3+2g+4g-2 CALCULATE AND COMBINE LIKE TERMS
SOLUTION:4f-5+6g
