Assuming you have log in base 2.
Join logarithms (always):
log2(6-2x)-log2(x) = log2( (6-2x/x) )
Then get rid of it! :)
(6-2x)/x = 2^3=8,
Solve the equation:
6-2x=8x ---> 10x=6 ---> x = 3/5.
Hey there!!
Domain - all the x values
Domain for this is
-6 < x ≤ 2
Interval notation = ( -6 , 2 ]
as one of the dots is not filled and for the domain we will always have to got from the left to right
Hope my answer helps!
To clear the fractions we multiply both sides by the least common multiple of all the denominators.
1/2 x + 2/3 = 4
Denominators 2 and 3, so multiply both sides by [Answer]: 6
3/4 x + 1 = 5/6
Denoms 4 and 6, LCM=12 Answer: 12
6/7 x - 2/3 = 5/21
LCM(7,3,21)=21 Answer: 21
3/5 + x/2 = 9
LCM(5,2) Answer: 10
25/4 = 6 + 1/2 x
LCM(4,2) Answer: 4
-6[6^5-(55-6^5)/3]
and just solve that
Answer:
The absolute error = 2 centimeters.
The desirable length = 45 cm
The minimum length = 43 cm.
The maximum length = 47 cm.
Step-by-step explanation:
Katie has been given a project to make a model car that is 45 centimeters long. The teacher has told her that variations in the length of up to 2 centimeters are acceptable.
Therefore, the absolute error = 2 centimeters.
The desirable length = 45 cm
The minimum length = (45 - 2) = 43 cm.
The maximum length = (45 + 2) = 47 cm. (Answer)
