The velocity of a pendulum changes at a rate of a(t) = 0.9' cos(0.2t) meters per second squared (where t is the time in seconds). At time t = 6, the velocity of the pendulum is 0.8

meters per second. By how much does the velocity change between t = 6 and t = 12

seconds?

Which expression can we use to solve the problem?

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
