Answer:
above is the answer to the question
Answer:
hello :
note : secy = 1 / cosy
tany = siny /cosy
sin y+cos y+tan y sin y = sin y+cos y+( siny /cosy)sin y
= ( siny cosy + cos²y + sin²y) / cosy
= (siny cosy +1) / cosy......because : cos²y+sin²y =1
= (siny cosy) / cosy + 1 / cosy
= (siny/cosy) × cosy + 1/cosy
sin y+cos y+tan y sin y = tany cosy + secy
Answer:
It would be 4/a
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
then, solving our equation
t = 9 / ( 450 × 0.04 ) = 0.5
t = 0.5 years
The time required to
accumulate simple interest of $ 9.00
from a principal of $ 450.00
at an interest rate of 4% per year
<span>is 0.5 years (about 0 years 6 months).</span>
