Answer: 120,000
Step-by-step explanation:
Let the question mark = x
x*1/100 = 1200
Multiply by 100 on both sides:
x = 1200*100
x = 120,000
It would be 67 because its the same decrease as the other.
X^+5x would be the answer
Answer:
Step-by-step explanation:
Given that,
Length of a rectangle, 
Width of a rectangle, 
We need to find the area of the rectangle.
We know that,
Area of a rectangle = l × b
Substituting all the values,
Hence, the area of the rectangle is 
.
1.
v x w = 8 i - 24 j + 15 k + 10 j - 12 i - 24 k =
= - 4 i - 14 j - 9 k
Answer: D )
2.
v x w = -16 i - 16 j - 18 k + 12 j + 48 i - 8 k =
= 32 i - 4 j - 10 k
Answer: C )
3.
The cross product:
< - 6, 7, 2 > x < 8, 5, -3 > =
= - 21 i + 16 j - 30 k - 18 j - 10 i - 56 k =
= - 31 j - 2 j - 86 k = < - 31, - 2, - 86 >
Vectors are perpendicular if: cos ( u, v ) = 0
< - 6 , 7. 2 > * < -31, - 2, - 86 > = 186 - 14 - 172 = 0
< 8, 5 , - 3 > * < - 31, - 2, - 86 > = -248 - 10 + 258 = 0
Answer: A ) < - 31, - 2 , - 86 >, yes.
