The source has chemical and potential energy which when switched on transforms into a chemical reaction. Potential energy is stored energy. A wire which is part of a circuit carries the electrical energy to the bulb which is a form of light energy. This completes the transformation of potential energy - chemical energy - electrical energy - light energy.
Answer:
C
Explanation:
The answer is not D because the money is doubling every n years. We do not need to know what n equals to know that since n is doubling, this is an exponential function. The graph in D is going at a constant rate, and exponential functions do not increase/decrease at a constant rate. This also eliminates A. B is not correct because the money will keep increasing and not decrease eventually like the graph in B shows.
Answer:
x = 21
Explanation:
The two remaining angles must add to 90 degrees since a triangle adds to 180
3x+6 +x = 90
4x+6 =90
4x = 90-6
4x = 84
Divide by 4
4x/4 = 84/4
x = 21

Answer:
750
Explanation:
<em>I'm gonna make my best effort here... (it's been a long hecking time since SAT math last year :P)</em>
Set both equation equal:
5x = -15x + 3000
20x = 3000
x = 150
Plug into any equation because both are equal anyway:
y = 5x
y = 5(150)
y = 750
(a, b) --> (x, y)
The point is (150, 750) and b = 750
