Step-by-step explanation:
4[5x-3x(2-2x)]
=4[5x-6x+6x^2]
=4[-x+6x^2]
=-4x+24x^2
Answer:
divide 300 feet by 50 which is 6, divide 125 ft by 50 which is 2.5. Therefore your dimensions are 6 in by 2.5 in
if you're in putting in the computer it may want 2.5 in fraction form which is 2 1/2 in or in improper fraction form 5/2 in
Step-by-step explanation:
Answer:
a. 30 meters per second
b. -10 meters per second
Step-by-step explanation:
a. Average rate of change for the height from 0 to 6.6 secs can be calculated using the formula, ![m = \frac{H(b) - H(a)}{b - a}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7BH%28b%29%20-%20H%28a%29%7D%7Bb%20-%20a%7D%20)
Thus,
Where,
![a = 0, H(0) = 0](https://tex.z-dn.net/?f=%20a%20%3D%200%2C%20H%280%29%20%3D%200%20)
![b = 6.6, H(6.6) = 198](https://tex.z-dn.net/?f=%20b%20%3D%206.6%2C%20H%286.6%29%20%3D%20198%20)
Plug in the values into the formula:
![m = \frac{198 - 0}{6.6 - 0}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7B198%20-%200%7D%7B6.6%20-%200%7D%20)
![m = \frac{198}{6.6}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7B198%7D%7B6.6%7D%20)
![m = 30](https://tex.z-dn.net/?f=%20m%20%3D%2030%20)
b. Average rate of change for the height from 8.8 to 13.2 secs = tex] m = \frac{H(b) - H(a)}{b - a} [/tex]
Where,
![a = 8.8, H(8.8) = 44](https://tex.z-dn.net/?f=%20a%20%3D%208.8%2C%20H%288.8%29%20%3D%2044%20)
![b = 13.2, H(13.2) = 0](https://tex.z-dn.net/?f=%20b%20%3D%2013.2%2C%20H%2813.2%29%20%3D%200%20)
Plug in the values:
![m = \frac{0 - 44}{13.2 - 8.8}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7B0%20-%2044%7D%7B13.2%20-%208.8%7D%20)
![m = \frac{-44}{4.4}](https://tex.z-dn.net/?f=%20m%20%3D%20%5Cfrac%7B-44%7D%7B4.4%7D%20)
![m = -10](https://tex.z-dn.net/?f=%20m%20%3D%20-10%20)
<u><em>Recycling can help reduce garbage, but items such as disposable diapers cannot be recycled.</em></u>
<em>The landfill, along with many other considerations, is paying the price for our practice in over population. We have spent our immense wealth on sex and reproduction and convenience with the result of things like diapers which, once used, cannot be recycled. It is a point really well taken. We cannot keep on filling our land and oceans with products that cannot be disposed of any other way. We need to be considering alternate ways of accomplishing the same thing. </em>
