Would appreciate the . the equation governing a body travelling in a water channel is given by the following equation: dv/dt = 1 - v2 (v2 is “v square”)
plot the velocity time graph for the object and determine the final velocity and the time taken to reach this velocity.

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
