Which of the following can a cell contain?

1: ) a number

2: ) a word

3: ) a function

4: ) all of these

(my first guess was #3, just to be sure)

D. All of these

A cell contains of the options listed therefore it is D

Definitely 3 because a cell can contain many functions

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
