Answer:
$8100·1.024^28
Step-by-step explanation:
The future value formula is ...
FV = P(1 +r/n)^(nt)
where P is the principal invested, r is the annual interest rate, n is the number of times per year interest is compounded and t is the number of years. Putting the given numbers in place of the corresponding variables gives the expression you want:
FV = $8100(1 +.048/2)^(2·14)
FV = $8100·1.024^28 . . . . . simplified
As 9 feet of fabric are needed for one skirt, and Arlen has double that amount of fabric, she can make two skirts
divide the shape into 2 triangles and 1 rectangle
left triangle :
hypotenuse = 7 in
height = 6 in
base = x
find the base using pythagoras theorem
x = √( 7² - 6² )
x = √13
x = 3.6 in
find it's area
6 × 3.6 ÷ 2 = 10.8
right triangle :
hypotenuse = 9 in
height = 6 in
base = x
find the base using pythagoras theorem
x = √( 9² - 6² )
x = √45
x = 6.7 in
find area
9 × 6.7 ÷ 2 = 30.15 in
middle rectangle :
16 in - left tri. base = base
16 - 3.6 = 12.4
find area
6 × 12.4 = 74.4
sum of the area
10.8 + 30.15 + 74.4 = 115.35
