Step-by-step explanation:
<u>Rule:</u>
When exponents multiply, they're adding.
<u>Multiply:</u>
Option A is correct.
? = 2. Thats the only one i got that equals 8xy^2. Not sure if its right tho.
A is the answer. 204/4 is 51, 306/6 is 51,etc. The car travels 51 miles every 1 hour.
18 is 60+35=95 180-95= 85 so ?=85°
P= 2500
r= 0.0465
A= P. e^(rt)
Where:
A = final mount
P = principal investment
r= rate
T= time (years)
To double it:
2 x 2500 = 2500 e^(0.0465 x t)
(2 x2500)/2500= e^(0.0465 x t)
2= e^(0.0465 x t)
Ln 2 = Ln e^(0.0465 x t)
Ln2 =0.0465t (Ln e)
Ln2 = 0.0465 t
t = Ln2 /0.0465
t= 14.91 years
Triple:
3 x2500 = 2500 e^(0.0465 t)
(3 x 2500 ) /2500 = e^(0.0465 t)
3 = e^(0.0465 t)
ln3 = ln e^(0.0465 t)
ln3 = 0.0465t Lne
ln3= 0.0465t
ln3/0.0465 =t
t= 23.63 y
