Inequalities and systems of inequalities A rectangular football field is xcm in length and 70m in width. If its perimeter is greater than 350m and its area is less than 7560m2, the value range of X is obtained

Cm? It should be m
From the meaning of the title, it is concluded that:
2（70+x）＞350
70x＜7560,
Then, 105 ＜ x ＜ 108

It is known that the manufacturer can make a profit of 0.2 points for every 1ml of beverage sold, and the maximum radius of the bottle that the manufacturer can manufacture is 6cm Q: (1) what is the radius of the bottle to maximize the profit of each bottle? (2) When the bottle radius is large, the profit of each bottle is the smallest? Please write the process, thank you
16. If the equation of motion of a body is s = 7T ^ 2-13t + 8, then its instantaneous velocity at t = () is 1 Note: if the interval is | T, t + △ x |, then △ y = 7 △ x ^ 2 + 14T △ x + 7T ^ 2-13t-13 △ x + 8-7t ^ 2 + 13t-8 = 7 △ x ^ 2 + 14T △ x, then △ Y / △ x = 7 △ x + 14T, so 14T = 1, t = 1 / 14. But the answer is 1?
