Answer:
30
Step-by-step explanation:
45-15
Sin2x=2sinxcosx, cos2x=1-2sin^2x
sin(2x)+cos(3x)=2sinxcosx+cos(x+2x)
cos(x+2x)=cosx(1-2sin^2(x))-sinx2sinxcosx
sin(2x)+cos(3x)=2sinxcosx(1-sinx)+cosx(1-2sin^2(x))
Example:
Proportionality=1
5=5x
Divide both sides by 5 , and you get 1=x,
so the proportionality is 1
Answer:
$764.42
Step-by-step explanation:
The account balance is given by the formula ...
A = P(1 +rt)
where P is the principal invested, r is the annual rate, and t is the number of years. Here, we assume 52 weeks in the year, since the time period is given in weeks.
Filling in the numbers, we have ...
A = $750(1 +0.025(40/52)) = $764.42
Darren's investment will be worth $764.42 at the end of 40 weeks.
