do you need the work?
Step-by-step explanation:
a = 2i + j - k
b = -1 -7j + k
a × b = (2i + j - k) (-1 + 7j + k)
-2i + 14ij + 2ik - j + 7j^2 + jk + k -7jk - k^2
-2i + 14ij + 2ik -j +7j^2 +jk - 7jk + k - k^2
-2i + 14ij + 2ik - j +7j^2 - 6jk + k - k^2
Answer:
(c) Equation which can be used to find r, the cost in dollars to park s nights is r = 24.99 s
Step-by-step explanation:
Here, the parking cost of 1 night at the airport = $24.99
Now, here the total number of nights the car is parked at airport = s
R = The total cost of parking s nights
Now, The cost for parking s nights = s x ( Cost of parking 1 night)
= s x ($24.99) = 24.99 s
Also the cost for parking s nights = r
⇒ r = 24.99 s
Hence, equation which can be used to find r, the cost in dollars to park s nights is r = 24.99 s
