Answer: 
Step-by-step explanation:
We are given the following formula, used to calculate the value of an used car according to the years after the car was originally bought:
Where 
is the price of the car when it was bought new, and 
is the number of years the car was used.
Solving the formula with the given data:
This is the value of the car according to the formula.
However, this value can be approximated to:
Answer:26.39
Step-by-step explanation:70-29.52-33.76+19.67=26.39
well It never could be less than both numbers.
the LCM of 2 numbers shd either be greater than the 2 numbers .... or the answer should be equal to either one of the numbers ...
lets see some examples to prove this conclusion:
now, lets find the LCM of 2 and 6 ... so if we do it ... we get the answer 6 .. which is ..as we said equal to one of the numbers
another example : 5 and 7 ... in this ... if we do it .. .we get the LCM as 37 ... which is greater than both the numbers
another case where both the numbers are same ....
where we need to find the LCM of 7 and 7 ... the answer will be 7 itself .....
Sin 2 x + sin x = 0
( sin 2 x = 2 sin x cos x )
2 sin x cos x + sin x = 0
sin x ( 2 cos x + 1 ) = 0
sin x = 0
x 1 = 0
x 2 = π
or: 2 cos x + 1 = 0
2 cos x = - 1
cos x = -1/2
x 3 = 2π/3
x 4 = 4π/3
