we are supposed to find
The derivative of the function ![A=620(1.786)^t](https://tex.z-dn.net/?f=%20A%3D620%281.786%29%5Et%20)
Differentiate both the sides wit respect to t we get
![\frac{dA}{dt}=\frac{d620(1.786)^t }{dt}\\ \\ \text{Take out the constant term we get}\\ \\ \frac{dA}{dt}=620\frac{d(1.786)^t }{dt}\\ \\ \text{Now using the formula }\\ \\ \frac{da^x}{dx}=(lna) a^x\\ \\ \frac{dA}{dt}=620*ln(1.786)(1.786)^t\\ \\ \frac{dA}{dt}=359.587(1.786)^t\\](https://tex.z-dn.net/?f=%20%5Cfrac%7BdA%7D%7Bdt%7D%3D%5Cfrac%7Bd620%281.786%29%5Et%20%20%20%7D%7Bdt%7D%5C%5C%20%5C%5C%20%5Ctext%7BTake%20out%20the%20constant%20term%20we%20get%7D%5C%5C%20%5C%5C%20%5Cfrac%7BdA%7D%7Bdt%7D%3D620%5Cfrac%7Bd%281.786%29%5Et%20%20%20%7D%7Bdt%7D%5C%5C%20%5C%5C%20%5Ctext%7BNow%20using%20the%20formula%20%7D%5C%5C%20%5C%5C%20%5Cfrac%7Bda%5Ex%7D%7Bdx%7D%3D%28lna%29%20a%5Ex%5C%5C%20%5C%5C%20%5Cfrac%7BdA%7D%7Bdt%7D%3D620%2Aln%281.786%29%281.786%29%5Et%5C%5C%20%5C%5C%20%5Cfrac%7BdA%7D%7Bdt%7D%3D359.587%281.786%29%5Et%5C%5C%20)
Answer:
<h2>Direction is represented by +9, indicating that is moving in a positive direction (upwards).</h2><h2>Zero is the reference point.</h2>
Step-by-step explanation:
So, basically, we need to apply a reference system to express directions, because all movements are represented respect to a reference point. In this case, number zero represents that reference point, which is located in the ground, setting this reference point we can measure the distance that Xavier traveled upwards the apple tree.
Geometric mean would be 464
Answer:
Step-by-step explanation:
The answer for the first one is 160 in 2
-6 it is just the opposite of the number. So a positive would be a negative and a negative a positive. So the answer to your question is -6.
