Answer:
Step-by-step explanation:
The equation is v=1/3πr³h
Multiply both sides of equation by 3 to get
3v=πr³h
Divide both sides of the equation by πh to get
3v/πh = r³
Apply cube root on both sides of the equation as;
Answer:
Point A (2.5, 14)
Step-by-step explanation:
The function for the charging fee, y, would be the initial $2 plus $4/hour for the charging time, x. This can be written as:
y = 4x + 2
Technically, both points A and C would not fall on theis line.
A: 2.5*4 + 2 = 12, not 12
C: at x = 0, there the equation still returns a $2 initial fee. So this should be (0,2) according to the equation. But it also makes sense to state that if the charging station is not used, there would be no charge. So a better way of expressing the equation would be to state that:
y = 4x + 2 for x > 0
Conclusion: Point A (2.5, 14) would not fall on this line.
-3(8-10) subtracting is the same as adding the opposite
-3(-2) multi. Negative times a negative becomes a positive
