The train travels at 5.5km per hour.
We know that in x hours it will advance by x*5.5 km.
Hence we need to solve x*5.5=82.5, hence x=82.5/5.5=15
It will take 5 hours
Answer:
Find the derivative using the chain and power rules.
-6csc^(2 )(x^(3)-2x^(2))(3x^(2)-4x)
Step-by-step explanation:
Algebraic expressions are combinations of variables , numbers, and at least one arithmetic operation.
Your example: 5+6a+11b
Term: Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable or variables.
Your example: 5, 6a, 11b
Factor: Something which is multiplied by something else. A factor can be a number, variable, term, or a longer expression.
Your example: 5, 6, a, 11, b
Coefficient: The numerical factor of a multiplication expression that contains a variable.
Your example: 6, 11
Constant: A number that cannot change its value.
Your example: 5
Answer: factors are 5, 6, a, 11, b
That depends on the length of the phone
