if an object is shot upward with an initial velocity, v0, in feet per second (ft/s) the velocity, v, in fr/s is given by the formula v=v0-32t, where t is time in seconds. find the initial velocity of an object if the velocity after 3 seconds is 23 ft/s

When y’all answer can y’all explain too !

What is the explicit formula for this sequence? -7, -4, -1, 2, a.) an = 8 + (b - 1)3 b.) an = -7 + (n - 1)3 c.) an = 3 + (n -1) (-7) d.) an = -7 + (n - )

As voters exit the polls, you ask a representative random sample of voters if they voted for a proposition. if the true percentage of voters who vote for the proposition is 63%, what is the probability that, in your sample, exactly 5 do not voted for the proposition before 2 voted for the proposition? the probability is
