Which equation can be used to find the unknown length, b, in this triangle? 5 in
b
4 in
O 42+b? -52
O42-b? - 52
52.42 -b?
052+6²-4²

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

whats the

answer

you start with $5 and save $10 a week until you have at least $45wer
