Five times a number is 21 less than twice the opposite of the number. what is the number?

Find the area of a parallelogram with base 15 yards and height 21 2/3

The table below shows the approximate height of an object x seconds after the object was dropped. the function h(x)= -16x^2 +100 models the data in the table. for which value of x would this model make it the least sense to use? a. -2.75 b. 0.25 c. 1.75 d. 2.25

20 ! need ! which exponential function is represented by the table? f(x) = 0.2(0.5x)f(x) = 0.5(5x)f(x) = 0.5(0.2x)f(x) = 0.2(0.2x)
