Answer:
Cost of game after discount = 72 - 20% of 72 = $57.6
Cost after tax = 57.6 + 7.5% of 57.6 = $61.92
So, the required cost is $61.92.


That's the logarithmic form. Do you need with solving the equation too?
Answer:
The integers are 4 and 6
Step-by-step explanation:
4 X 6 = 24
4 is two less than 6
Answer:
Part 67)
and 
Part 68)
or 
Step-by-step explanation:
Part 67) we know that
The solution of the number line is the interval -------> (-2,3)
All real numbers greater than -2 and less than 3
so
The compound inequality could be
and 
"And” indicates that, both statements must be true at the same time
Part 68) we know that
The solution of the number line is the interval (-∞,-1] ∪ [1,∞)
All real numbers less than or equal to -1 or all real numbers greater than or equal to 1
The compound inequality could be
or 
"Or” indicates that, as long as either statement is true, the entire compound sentence is true
Not much can be done without knowing what

is, but at the least we can set up the integral.
First parameterize the pieces of the contour:


where

and

. You have


and so the work is given by the integral
