Answer:
9.694 years
Step-by-step explanation:
Let the investment is $P.
So, we are asked to determine the time it will grow to triple with the compound interest rate of 12%.
Let the time is y years.
So, from the formula of compound interest we can write
⇒ 
⇒ 
Now, taking log both sides we get,
y log 1.12 = log 3 {Since, 
}
⇒ 0.04922y = 0.477712
⇒ y = 9.694 years (Answer)

Answer:
90
Step-by-step explanation:
6x4^2+(-2)x3=
6x16-2x3=
96-6=
90
We know that
angle (3x) and angle (9x) are supplementary angles
so
3x+9x=180°------> 12x=180°------> x=180°/12-----> x=15°
angle (9x) and angle (1) are supplementary angles
so
9x+∡1=180---------> 9*15+∡1=180
∡1=180-9*15---------> ∡1=180-135------> ∡1=45°
the answer is
∡1 is 45°
alternative method
angle 1 = angle 3x----------> vertical angles
∡1=3x-----> 3*15-----> 45°
