Answer:
$3743.43
Step-by-step explanation:
The amount is given by the formula ...
A = Pe^(rt)
where P is the principal, r is the annual rate compounded continuously, and t is the number of years. Filling in the values, we get ...
A = $1600·e^(0.0425·20) = $1600·e^0.85
≈ $1600·2.33964685 ≈ $3743.43
The amount in the account will be $3743.43.
x + 30% x = 97.5 $
x+ 0.3 x = 97.5
x(1+0.3) = 97.5
1.3 x = 97.5
x= 97.5/ 1.3= 75 $ its original price
The answer would be 90 because it takes 60 days to become a half-life so the the half of 720 is 360 the 180 then 90
A=<4.60,7.20>
b=<5.10,2.70>
The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions,
a.b=4.6*5.1+7.2*2.7
=23.46+19.44
=42.9
