The excluded values are the values that the variable cannot take on because it makes the overall expression undefined.
For example, we can't have in the expression because is undefined.
For both of these problems you do the same sort of thing, with some factorization along the way:
If or , the denominator is 0 and we have an undefined expression, so these are the excluded values.
If or , we get an undefined expression.
1510*0.02=$30.20 which is larger than $20.00. 2%= 0.02
Answer:
b and c, b and c are same
Step-by-step explanation:
Only a and d can be evaluated using simple substitution.
For a, integral of the square root of (x-1)dx i.e
let y = x-1
dy = dx
It becomes integral square root of ydy, ∫√ydy
which is can easily be evaluated and y is substituted back.
For d, integral of x times the square root of the quantity x squared minus 1
let y= x squared minus 1
then dy = 2xdx
dx = dy/2x
It becomes integral x times square root of y dy/2x
∫x√ydy/2x=∫√ydy/2=1/2∫√ydy which can easily be evaluated and y is substituted back
