The position of a mass tied to a spring hanging from the ceiling is given by x (t) = 3e-2t cost, in which positive values of x represent positions below the equilibrium position (x = 0). Assume the mass begins moving at time t = 0. When does the mass reach its highest point? O

a. at t = Arctan (-2) + pi
b. at t = Arctan (2)
c. at = Arctan ( -1/2 ) +pi
d. at t = Arctan (-2) O at t = 7

What are the following algebraic equations. you need to post those if you want the answer

The correct answer is .44

Just add 10+3m the m means the roman numeral m is often used to indicate one thousand, and mm is used to indicate one million. for example, an expense of $60,000 might appear as $60m. sales of $3,000,000 might be written as $3mm. internet advertisers are familiar with cpm which is the cost per thousand impressions. so 10+3m= 300,000,010hope this and if it does can i have brainlest? if not tell me what i did wrong but i’m pretty sure i am right.
