A particle is moving along a straight line and t seconds later it passes the point O of line at velocity V(m/s) where V=A- In(t+B) and A and B are positive constants. Also it is known that when t-10, the acceleration of the particle is - 1/20(m/s²) and that the particle comes to rest when t = 100 seconds. Find the exact value of B and A correct to two decimal places. ​

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
