How would I solve this using derivative rules? I know the answer is 5/2x^2 but what I don’t understand is how you get that. Because with the power rule I thought you had to take the derivative of both separately, and the derivative of 5/2 is 0

  The constant factor remains a multiplier.

Step-by-step explanation:

The derivative of "a·f(x)" is a·f'(x). That is, the constant multiplier remains a constant multiplier, unchanged.

For ax^-1, the derivative is a(-x^-2) per the power rule. For your value of a=-5/2, this is ...

10 * 563.67 = 5636.7

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
