Answer:
b
Step-by-step explanation:
hope this helps im not very sure tho
U= {A,B,C,D,E,F,G}
X = {A, B, C, D}
Y = {A, C, E, F}
a) X or Y = {A, B, C, D} and {A, C, E, F} = {A, B, C, D, E, F}
B) X and Y = {A, B, C, D} or {A, C, E, F} = {A, C}
c) Complement of X = {A,B,C,D,E,F,G} - {A, B, C, D} = {B,D,G}
$2743.66
Data provided in the question:
Interest rate = 5%
Future value = $55,000
Time, t = 4.5 years
Now,
Since the interest is compounded quarterly
therefore,
Number of periods in a year = 4
Interest rate per period = 5% ÷ 4 = 1.25% = 0.0125
Total number of periods in 4.5 years = 4.5 × 4 = 18
also,
PMT = Future value × [ r × (( 1 + r )ⁿ - 1)⁻¹ ]
PMT = $55,000 × [ 0.125 × ( ( 1 + 0.0125 )¹⁸ - 1 )⁻¹ ]
or
PMT = $55,000 × 0.0498
PMT = $2743.66

all triangles have a total of 180 degrees
set up equation and solve
180=(2x+4)+(2x-9)+x
180=5x-5
185=5x
37=x
