Answer:
B. The vectors v and w are orthogonal because their dot product is <u> 0 </u>
Step-by-step explanation:
Given that :
v= - i - j
w= - i + j
Therefore;
vw = ( - i - j ) ( - i + j )
Taking each set of integer of the vector into consideration:
vw = ( -1 × - 1) ( -1 × 1)
vw = 1 - 1
vw = 0
Hence, we can conclude that :
The vectors v and w are orthogonal because their dot product is <u> 0 </u>
Answer: The correct answer is $ 3.50 per pound. If she buys 4 1/4 pound, we convert the 1/4 to the decimal 0.25. Take the total cost of $14.88 and divide it by 4.25, the amount of watermelon she bought and it equals $3.50 per pound.
14.88/4.25= 3.50
Step-by-step explanation:
Answer:
322 feet
Step-by-step explanation:
first lets plug in our value for s in the equation
.05(70)^2+ 1.1(70)
we then sqaure 70 to get
.05(4900) + 1.1(70)
Then multiply to get
245 + 77
then add to get
322 feet
