What is the average rate of change between 50 and 150
Alex73 [517]

Answer:

Your input: find the average rate of change of f(x)=x2 on the interval [50,150].

The average rate of change of f(x) on the interval [a,b] is f(b)−f(a)b−a.

We have that a=50, b=150, f(x)=x2.

Thus, f(b)−f(a)b−a=(150)2−((50)2)150−(50)=200.

Answer: the average rate of change is 200.

Explanation:

Calculate the average rate of change. x from x = π to x = 2 π (where x is measured in radians). Calculate the average rate of change. Determine the average rate of change for the function below, from t = − 2 to t = 8 . Calculate the average rate of change. Determine the average rate of change for the function below, from x = − 6 to x = − 3 .

1. A mutation is capable of reducing the amount of chlorophyll in the leaf. Would this also reduce the rate of photosynthesis?
Alex17521 [72]

Answer:

No.This is because the amount of the chlorophyll; ls not a limiting factor of photosynthesis.

Explanation:

Generally the three factors are regarded as the limiting factors of photosynthesis.These are the CO2 concentration,light intensity,and temperature.Fluctuations in the availability of these factors affects the rate of photosynthesis.

When the rate of a chemical reaction depends on  a lot of reactions for its progress.The rate of this reaction is determined or  limited by the slowest in the reactions. This series of reactions govern this chemical reactions are the limiting factors. The one that is slowing down the rate of the reaction is said to limit it.

in the case of photosynthesis,  a decrease in the amount of CO2,but no change in the amount of other factors would affect the rate of photosynthesis. This is applicable to other factors fluctuation too ,which limits  the rate of photosynthesis
