Cost of computer and monitor = $1500 Cost of printer = $650 Cost of external Hard Drive = $250 Therefore , Total cost of the system = $1500+$650+$250 = $2400 Now , there is an 10% increase in the cost of computer and monitor. Increase in the cost of computer and monitor = $1500*10/100 = $150 Hence , the revised cost of computer...http://www.enotes.com/homework-help/mrs-carter-decides-buy-computer-system-her-son-she-484577Mon, 27 Jul 2015 04:49:13 PSTAssuming that Mrs. Carter spent $1500 for both the computer and monitor...

Assuming that Mrs. Carter spent $1500 for both the computer and monitor together (as oppose to $1500 for the computer and $1500 for the monitor), if the computer and monitor cost 10% more, 10% of $1500 is $150. So, the computer and monitor would cost $1650. For the entire system, we would add all the parts together:$1650 + $650 + $250 = $2550 Following a similar process if the computer cost $1500 and the monitor cost $1500, then each would...http://www.enotes.com/homework-help/mrs-carter-decides-buy-computer-system-her-son-she-484577#1Mon, 27 Jul 2015 03:29:22 PSTMrs. Carter decides to buy a computer system for her son.

Mrs. Carter decides to buy a computer system for her son. She spends 1,500 dollars for a computer and LCD monitor, 650 dollars for a colour printer, and 250 dollars for an extdrnal hard.drive. What would be the total cost of the system if the cost of the computer and monitor cost 10% morre?http://www.enotes.com/homework-help/mrs-carter-decides-buy-computer-system-her-son-she-484577#2July 27, 2015, 3:21 am PST`10/(5x^2-2x^3)`=`10/(x^2(5-2x))` `` =`A/x+B/x^2+C/(5-2x)`...

sin(-b) reflects over the x-axis only because sin(-b)=-sin(b). cos(-b) reflects over the y-axis. sin(-b) reflects over the y-axis also, but the effect is the same as a reflection over the x-axis since sine is an odd function. In general, -f(x) reflects the graph of f(x) over a horizontal axis while f(-x) reflects the graph of f(x) over the vertical axis.http://www.enotes.com/homework-help/f-x-sin-3x-g-x-sin-3x-describe-relationship-483917Thu, 23 Jul 2015 21:01:46 PSTf(x)=cos(x);g(x)=cos(2x) The graph of g(x) has the same amplitude as...

f(x)=cos(x);g(x)=cos(2x) The graph of g(x) has the same amplitude as the graph of f(x). The period of g(x) is pi units, where the period of f(x) is 2pi units. This means that g(x) completes two cycles for every 1 cycle of f(x). The graph of g(x) is compressed horizontally compared to the graph of f(x). The graphs coincide every 2pi units.
