The amount in account after 7 years is $ 5499.445
<em><u>Solution:</u></em>
<em><u>The formula for total amount in compound interest is given as:</u></em>
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested or borrowed for
Here given that,
A = ?
P = 4000
t = 7 years
n = 2 ( since compounded semi annually)
<em><u>Substituting the values in formula, we get</u></em>
Thus amount in account after 7 years is $ 5499.445
Answer:

Step-by-step explanation:
1 km = 1,000 m
3 * 3 = 9 km
9 * 1,000 = 9,000 m
Answer:
x>10>6<0
Step-by-step explanation:
the two length are 10&6 respectively.
on a normal note, the two length of a triangle is equal.
Therefore, x>10>6<0

Answer:
(C)10(√3 +1)
Step-by-step explanation:
let x be DC then
from fig. tan45° = DC/BC
we get DC = BC
then we get AC = 20+x
tan 30° = DC /BC
(1/√3)= (x)/(20+x)
20= x(√3-1)
x= 20/(√3 -1)
rationalize we get
x = 20(√3 +1)÷(3-1)
x = 10(√3+1)
