PLEASE HELP: a ferris wheel with a radius of 20 m rotates once every 40 s. A passenger gets on at the lowest point which is 1 m above the ground. This situation can be modelled by the equation:
where h is the distance above the ground in metres and t is the time in seconds.

Determine the times (accurate to one decimal place) in the first cycle when the height of the passenger is 15 m or higher. An algebraic solution is required

Which conjunction is disjunction is equivalent to the given absolute value inequality? |x+2|< 18

Carla was trying to decide what to do saturday evening. she has $100 available to spend for the evening. she has narrowed her choices down to these events: braves game, a concert of an artist she likes, or the georgia aquarium. admission to the braves game is $25, hot dogs cost $10, sodas cost $5. the concert costs $25 for admission, $20 for a souvernir t-shirt, and $10 for a soda. the georgia aquarium has the show of a lifetime with an all you can eat and drink that costs $100. carla does not want to take any driving chances, so in addition to the cost of the aquarium, she will also need to pay for her uber/lyft, which is $15 each way. which option should carla choose if she wants to spend the least? based on that choice, what then is carla's oppotunity cost? fully explain your answer in at least one paragraph.
