Answer:
You will have $623.3441462 in your account after 7 years
Step-by-step explanation:
The formula of the compounded interest is A = P , where
- A is the new value
- P is the initial value
- r is the rate in decimal
- n is the number of periods
- t is the time in years
∵ You are opening a savings account with $500
∴ P = 500
∵ The bank offers 3.2% interest, compounded yearly
∴ r = 3.2% ⇒ divide it by 100 to change it to decimal
∴ r = 3.2 ÷ 100 = 0.032
∵ The interest is compounded yearly
∴ n = 1
∵ The time is 7 years
∴ t = 7
→ Substitute these values in the rule above to find A
∵ A = 500
∴ A = 500
∴ A = 623.3441462
∴ You will have $623.3441462 in your account after 7 years
Part 1) <span>Find the area
we know that
the area of the triangle is
A=b*h/2
in this problem
b=9
h=12
so
A=9*12/2-----> A=54 units</span>²
the answer part 1) is
Area=54 units²
Part 2) <span>Find the area of the kite
see the picture attached with letters to better understand the problem
we know that
The area of a Kite is </span><span>half the product of the diagonals
</span><span>
step 1
find CB
applying Pythagoras Theorem
AB</span>²=AC²+BC²------> BC²=AB²-AC²-----> BC²=5²-3²----> BC²=16
<span>BC=4
so
the diagonals are
(10+4) and (3+3)---------> 14 and 6
Area=(1/2)*[14*6]----> Area=42 units</span>²<span>
the answer Part 2) is
the area of a kite is 42 units</span>²
