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 answer will be

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

she will travel a distance in the range of 3 - 11 miles

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

2                   4   = not 1, and 4

3                   2

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
