Glucose, which is a monosaccharide, is a carbohydrate produced through the photosynthesis process in plant leaves that contain the chloroplasts. The glucosethat plants do not use immediately is converted into larger molecules of glucoseand stored as starch for later use as an energy source. This is the main function of glucose in plants .
The average velocity of the bottle rocket are two given time intervals is 30 m/s and 20 m/s respectively, while the instantaneous velocity at 4.5 seconds is 22 m/s.
The given parameters;
- s(t) = -9t² + 103t + 403
- time interval (4.499, 4.5), and (4.5, 4.501)
The average velocity of the bottle rocket over the intervals is calculated as follows;
when the interval = [<em>4.499, 4.5</em>]
![s(4.499)= -9(4.499)^2 + 103(4.499) + 403 = 684.22 \ m\\\\s(4.5) = -9(4.5)^2 + 103(4.5) + 403 = 684.25 \ m](https://tex.z-dn.net/?f=s%284.499%29%3D%20-9%284.499%29%5E2%20%20%2B%20103%284.499%29%20%2B%20403%20%3D%20684.22%20%5C%20m%5C%5C%5C%5Cs%284.5%29%20%3D%20%20-9%284.5%29%5E2%20%20%2B%20103%284.5%29%20%2B%20403%20%3D%20684.25%20%5C%20m)
