Answer:
tan (a+b) = 2.27 or (345/152)
Step-by-step explanation:
a and b are in the fourth quadrant
sin a = -12/13 tan a = - 12/5 = - 2.4
cos b = 20/29 tan b = - 21/20 =.1.05
tan (a+b) = (tan a + tan b) / (1 - tan a * tan b)
= (-2.4 + - 1.05) / ( 1 - (-2.4)*(-1.05))
= (-3.45) / (-1.52)
= 2.27
Answer:
A = $2200(7.612) = $16,747.28
Step-by-step explanation:
You don't say whether this is simple interest or compound interest. I will assume you meant compound interest, for which the appropriate formula is
A = P(1 + r)^t, where P is the principal amount, r is the interest rate as a decimal fraction, and t is the time in years. Then:
A = $2200(1 + 0.0725)^29, or
A = $2200(1.0725)^29, or
A = $2200(7.612) = $16,747.28
Plug in -3 in the x.
4(2)(-3)= -24.
