A carpenter uses a 12-foot timber to brace a wall frame 8 feet high.
8-foot Wall Frame
12 Foot Beam
2
If the construction site is level, what is the
distance the timber will extend out from the
wall?

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
