The function P(t) = 37.25e0.0096t the population, in millions, of California t years since 2010. Assuming this trend continues, approximate the number of years it will take California's population to reach 50 million. Round your answer to two decimal places. approximates

Francine throws a wrench into the air from the bottom of a trench 10 feet deep. Its height t seconds later is given, in feet, by h = -16t + 34t – 10 a. When will the wrench attain its maximum height? Round your answer to two decimal places and choose the correct units. O A. meters O B. seconds OC. hours OD. feet b. According to the function, how do you know your answer to part (b) is where the maximum height is attained and not the minimum height? O A. The leading coefficient is positive, so the graph is concave up O B. The leading coefficient is positive so that graph is concave down OC. The leading coefficient is negative, so the graph is concave down OD. The leading coefficient is negative, so the graph is concave up

The population of the village is expressed by the model y = 7800(1.25)3. Find the growth rate of the population.

Element X is a radioactive isotope such that its mass decreases by 20% every year. Ifan experiment starts out with 730 grams of Element X, write a function to representthe mass of the sample after t years, where the monthly rate of change can be foundfrom a constant in the function. Round all coefficients in the function to four decimalplaces. Also, determine the percentage rate of change per month, to the nearesthundredth of a percent.
