Question

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

Answer 1

for the top one its $620

Answer 2

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

Answer 3

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

Answer 4

p=l^2r find p if l=12 amperes r-2 ohms

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