Step-by-step explanation:
We can break the problem into three parts,
tan45 = sin(45)/cos(45)=

Therefore, the solution is sqrt(3)/3
Answer:
Greg pays more interest than Linda
He pays $17.45 more
Step-by-step explanation:
Greg
P=$1975
R=5%=0.05
T=3 years
Simple interest=P×R×T
=$1975×0.05×3
=$296.25
Linda
P=$1975
r=4.5%=0.045
n=1
t=3
Linda's Interest is compounded once per period, so we this formula
Compound Interest =P(1+r)^t
=$1975(1+0.045)^3
=$1975(1.045)^3
=$1975(1.141166125)
=$2,253.80
Interest paid=$2,253.80-$1975
=$278.8
Answer:
x = 40
Step-by-step explanation:
1/2x - 18 = 2
1/2x = 2 + 18
1/2x = 20
x = 20 / 1/2
x = 20 * 2/1
x = 40
