Suppose we have a pendulum that is "y" feet long. our pendulum makes one complete swing in "t" seconds. assume "y" and "t" are related by the formula y = .9 t2. if the pendulum is less than 4 feet long, what is the range of values for "t"?

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

answer. d.289 hope that

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
