I=PRT
Interest=I
P=principal
R=rate in decimal
T=time in years

given
asuming 640 is the principal and not the interest
P=640
R=3%=0.03
T=2

I=640*0.03*2
I=19.2*2
I=38.4

interst=$38.40

Find one solution for the equation. Assume that all angles involved are acute angles. tangent (3 Upper B minus 32 degrees )equal

raketka [301]

Answer:

Step-by-step explanation:

Equation given

tan(3B-32 ) = cot ( 5B +10 ) = tan [ 90 - ( 5B + 10 ) ]

tan(3B-32 ) = tan (90 - 5B - 10 )

(3B-32 ) = (90 - 5B - 10 )

8B = 32 + 80

B = 14° .
