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.
Answer:
Graph A, <em><u>copy and paste the link to see the graph i will but the link in the comment</u></em>
Step-by-step explanation:
If we see this question mathematically we find that graph A is showing a better slope than graph B.
More slope means larger y- intercept, which shows more decrease in sales of gas fueled cars.
This decrease in fact is an illusion, while data-wise decrease of the gas fueled cars in both the graphs are same.
Therefore graph A will be the preferred graph for presentation which appears to decrease more.
if i could get brainliest that would be great :)
6x(5x+10)
30x^2+60x is the answer
Answer:
no
Step-by-step explanation:
1 x 7 = 7 but 2 x 7 does not equal 17
Answer: 75 meters
Step-by-step explanation:
Given: The variable ll models the anchor's elevation (in meters) relative to the water's surface t seconds after the ship drops its anchor as
To find the initial height, substitute t=0 in the equation, we get
Therefore, the initial height of the anchor = 75 meters .
