What is this number in standard form?
(8 X 100) + (4 x 1) + (6 x 1/100 ) + (3 x 1/1000)

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

Ineed here’s a picture of the question

2f(x)= x+3 if 4 < x < 8 2x if x 28 2
