Loyd is floating in his boat 2 km from the straight shoreline of a still lake .Standing at a location 4 km from the point on the shoreline closest to Loyd is his beloved Ofeld.He plans to get to Ofeld in the shortest time possible by rowing 4 km/hr in straight line toward point A on the shoreline and then by walking 5 km/hr from point A to Ofeld in straightline.The objective function in this situation is determined by summing up the time of rowing towards A and the time walking from A to get to Ofeld and this is given byT(d) =d² +44+4-d5where T = is the total time (shortest time possible) and d = distance between the point on the shoreline closest to Loyd and point A.Determine the minimum time T.O 2 hours and 40 minutesO 1 hour and 40 minutesO 2 hours and 6 minutesO 1 hour and 6 minutes

GivenT(d)=d2+44+4-d5 We are required to find the minimum value of T.

Suppose that a baseball is thrown upward with an initial velocity of 110 feet per second (75 miles per hour) and it is released 7 feet above the ground. Its height h after t seconds is given by h = - 16t² + 110t+7. After how many seconds does the baseball reach a maximum height? Estimate this height.
The Cloud North American cloud computing revenues from 2008 and projected to 2020 can be modeled by y = 0.231x2 - 2.242x + 11.101, where xequals the number of years after 2000 and y equalsthe revenue in billions of euros. For what years from2008 to 2025 does this model estimate the NorthAmerican cloud computing revenues to be at least65.89 billion?
When a ball is tossed into the air, the height h is feet of the ball t seconds from the time that the ball is released is given by the formula h(x)=−16t2+80t+4. Determine the maximum height of the ball and the time that the ball will obtain that height
A railway line connects Parnac station with Rougelle station. The distance between these two stations is 150 km. -a train departs from Parnac at 17:10 and stops at Bernouille station at 17:40. Bernern is 60 km from Parnac - He leaves Bernouille twenty minutes later and crosses the Sévillon train station at 18:30. The Sévillon train station is 45 km from Rougelle. He continued his journey at the same speed until Rougelle station. -Another train leaves Rougelle at 17:35 and arrives at Sévillon at 18h. After 10 minutes of waiting he leaves to reach Bernouille at 18:40 and stops 10 minutes. He finally joined Parnac at 19:20. "At what time and how far from Rougelle do the trains intersect?"

Two collaborators, Nicolas and Felipe, are talking about the order they received with the size of four new pieces that will be produced. Each of the collaborators received the request on a piece of paper, but both were careless and ended up missing some information. Before asking for information about the order, they decided to talk and try to find out which measures were missing. Nicolas' paper only has the average length, which is 17.2 meters. The paper with the order that Felipe has, about the same pieces, contains the information that the median length is 17.0 meters. From the data they have, they were able to correctly conclude that the average between the lengths of the largest and smallest piece is:
