Answer:
f(0,0)=ln19
Step-by-step explanation:
is given as continuous function, so there exist
and it is equal to f(0,0).
Put x=rcosA annd y=rsinA

we know that
, so we have that


So f(0,0)=ln19.
Answer:
1. 1
2. 10
3. 12
Step-by-step explanation:
1. 5, 19, 24, 46, 77, then 98
2. -62, -47, -11, 38, then 56
<span>4(x - 3) - 5(x + 1) = 3
4x - 12 - 5x - 5 = 3
-12 - 5 - 3 = 5x - 4x
x = -20
