Nettet3. mar. 2016 · Find the rate of change of the area of a circle per second with respect to its radius when radius=5cm. Source. A = π r 2 ⇒ d A d r = 2 r π. So when r = 5 cm, d A d r = 10 π cm. But the answer is 10 π cm 2 /sec. I don't understand how time comes into picture when we are only talking about radius and area? NettetAverage Rate of Change. One way to measure changes is by looking at endpoints of a given interval. If y_1 = f (x_1) y1 = f (x1) and y_2 = f (x_2) y2 = f (x2), the average rate of change of y y with respect to x x in the interval from x_1 x1 to x_2 x2 is the average change in y y for unit increase in x x. It is equal to.
Nettet7. sep. 2024 · Determine a new value of a quantity from the old value and the amount of change. Calculate the average rate of change and explain how it differs from the … NettetThe rate of change would be the coefficient of x. To find that, you would use the distributive property to simplify 1.5(x-1). Once you do, the new equation is y = 3.75 + …
NettetCancelling out the d r on the lefthand side gives us the differential of volume with respect to time: d V d t = 4 π r 2 d r d t. Now, plugging in the rate of 7 i n. m i n. for d r d t and 16 i n. for the radius, the rate at which the volume is changing is: d V d t = 4 π ( 16 i n.) 2 ( 7 i n. m i n.) = 4 π ( 256 i n. Nettet11. nov. 2024 · One easy way to calculate a rate of change is to make a graph of the quantity that is changing versus time. Then you can calculate the rate of change by finding the slope of the graph, like...
