I don’t see no options? But if you simplify the answer is -30x^2 - 4x + 8 hope it helps
Answer:
Please clarify your question
Step-by-step explanation:
The area of the parallelogram spanned by the given vectors is equal to the magnitude of their cross product.
(i + j + k) × (-2i + 3j + k)
= -2 (i × i) - 2 (j × i) - 2 (k × i)
… + 3 (i × j) + 3 (j × j) + 3 (k × j)
… + (i × k) + (j × k) + (k × k)
= - 2 (j × i) - 2 (k × i) + 3 (i × j) + 3 (k × j) + (i × k) + (j × k)
= 2 (i × j) - 2 (k × i) + 3 (i × j) - 3 (j × k) - (k × i) + (j × k)
= 5 (i × j) - 3 (k × i) - 2 (j × k)
= 5 k - 3 j - 2 i
Then the area of the parallelogram is
||-2 i - 3 j + 5 k|| = √((-2)² + (-3)² + 5²) = √38
Number of people can hold in each car = 10
Solution:
Number of cars in the Blazing Bullet = 6
Total number of people can ride at one time = 60
Number of people can hold at one Bullet car = ?
Let n be the number of people in each car can hold.
Now write a equation to find the number of people in each car.
Number of cars × number of people in each car = Total number of people
⇒ 6 × n = 60
⇒ 6n = 60
Now, solving this equation.
⇒ 6n = 60
Divide both sides of the equation by 6.
⇒ n = 10
Hence 10 people can hold in each car.
