can someone help me with a few questions.
v=p(1+rt)  p=$500  r=.08 per year  t=3 years

s=4.9t2  find s if t- 4 seconds

p=l2r   l= 12 amperes  r= 2ohms

a=2w2+4hw  find a if w=7cm h=10cm

for the top one its $620

anonymous · Answer

the second one:
s = 4.9t^2
s = 4.9(4^2)
s = 4.9(16)
s = 78.4

anonymous · Answer

I don't understand what the other questions are asking.

anonymous · Answer

p=l^2r   find p if l=12 amperes  r-2 ohms

a=2w^2 + 4hw  find a if w=7cm  h=10cm
