A scientist is studying a new strain of bacteria. She places 10 bacteria cells in a nutrient- rich petri dish and discovers that the cells grow exponentially. The growth factor of the
bacteria is 3.5 cells per hour. What is the exponential function that models this scenario?
How many cells will the scientist have after 3 hours?

Grace is standing 18 feet from a lighthouse and kelly is standing 10 feet from grace. the angle that grace looks up to see the top of the lighthouse is 45°. the angle that kelly looks up to see the top of the lighthouse is y°. find the height, h, of the lighthouse. find the angle, rounded to the nearest tenth of a degree, in which kelly looks up to the top of the lighthouse. to the nearest tenth of a degree, find the value of x° . in two or more sentences, explain your calculations
