Answer:
48
Step-by-step explanation:
You can use a graphing calculator like desmos or draw your own graph to figure this out. Start by graphing each of those points. Then count the width and height. Multiply them to get the area. The width and height of the rectangle were 6 and 8, so the area is 48
i would just round 9.3 to 9 and 4.4 to 4 so i subtract 9-4 so that equals 5 so about a 5 mile diffrence
Answer:
Value of the stock traded was $5200.
Step-by-step explanation:
In this question it is given that trading company charges commission of $10 per trade or transaction plus $.025 per dollar value of stock.We have to calculate the value of stock we traded if total commission (commission on trade value + commission on trade) is $140.
Let the value of stock traded was $x.
Then commission on value of the stock = x×.025
Commission on transaction = $10
Total commission = 140 = ( .025x + 10)
⇒.025x = 140-10 = 130
x = 130÷.025 = $5200
So the value of the stock = $5200
Explanation:
Basically, you can do it in many ways. But just, in my opinion, exactly linear algebra was made for such cases.
the optimal way is to do it with Cramer's rule.
First, find the determinant and then find the determinant x, y, v, u.
Afterward, simply divide the determinant of variables by the usual determinant.
eg. and etc.
I think that is the best way to solve it without a hustle of myriad of calculations reducing it to row echelon form and solving with Gaussian elimination.
