Answer: ![||cu||=39](https://tex.z-dn.net/?f=%7C%7Ccu%7C%7C%3D39)
Step-by-step explanation:
Given
and ![c=-3](https://tex.z-dn.net/?f=c%3D-3)
is a vector with 3 times the vector u in opposite direction
![|u|=\sqrt{5^2+(-12)^2}\\|u|=\sqrt{25+144}\\|u|=13](https://tex.z-dn.net/?f=%7Cu%7C%3D%5Csqrt%7B5%5E2%2B%28-12%29%5E2%7D%5C%5C%7Cu%7C%3D%5Csqrt%7B25%2B144%7D%5C%5C%7Cu%7C%3D13)
![\therefore ||cu||=|3\times 13|\\\Rightarrow ||cu||=39](https://tex.z-dn.net/?f=%5Ctherefore%20%7C%7Ccu%7C%7C%3D%7C3%5Ctimes%2013%7C%5C%5C%5CRightarrow%20%20%7C%7Ccu%7C%7C%3D39)
option (a) is correct.
Answer:
(x, y) = ( 1, 10/3)
Step-by-step explanation:
2x + 3y + 12
6 - 4x + 3y = 12
Simplify the equation:
2x + 3y = 12
-4x + 3y = 6
Multiply both sides by -1:
2x + 3y = 12
4x - 3y = -6
Eliminate one variable by adding the equations:
6x = 6
Divide both sides by 6:
x = 1
Substitute the value of x into the equation:
-4 x 1 + 3y = 6
Solve the equation:
y = 10/3
A possible solution:
(x, y) = ( 1, 10/3 )
Check the solution:
2 x 1 + 3 x 10/3 = 6 -4 x 1 + 3 X 10/3 = 12
Simplify the expression:
12 = 12 = 12

Step-by-step explanation:
You will get P=70x+50 where x is is the number of cellphones sold. If 240 cellphones are sold, then the profit is 16850 dollars
Answer:
Option "B" and "C" are True
Step-by-step explanation:
Given time:
First 12.89
Second 13.52
Third 14.05
Find:
True statement
Computation:
Difference between first and second = 13.52 - 12.89 = 0.63
Difference between second and third = 14.05 - 13.52 = 0.53 (Second true)
Difference between first and third = 14.05 - 12.89 = 1.16 (Third true)
