Answer:
a = 6
b = 48
Step-by-step explanation:
3*2^1 = 6
3*2^4 = 48
Answer: 3
Step-by-step explanation:
the amplitude in a sin equation y = asin(bx) + c is equal to a
in y = 3sin(9x), a =3
the amplitude is 3
A=P(1+r/n)^(tn)
n=number of times per year compounded
A=amount
P=principal inveseted
r=rate in decimal
t=time in years
so
we want A=30000
r=12.4%=0.124
t=15
monthyl means n=12
30000=P(1+0.124/12)^(15*12)
solve for P
easy, just divide both sides by (1.01033)^180
4714.97=P
that much must be invested
