Here you go
2•k+10
(10•k)+(10•2)
is that in the answers? If not, do not put it in!
Answer: D
Step-by-step explanation:
The expression for x-value of the vertex is (-b/2a). Doing this will give you the time of 3.8125 seconds.
Just input that value back into the equation and you will get the max height of 242.56 feet.
54 is a composite number. 54 = 1 x 54, 2 x 27, 3 x 18, or 6 x 9. Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54. Prime factorization: 54 = 2 x 3 x 3 x 3, which can also be written 2 x 3³.
Answer:
Matrix multiplication is not commutative.
Step-by-step explanation:
Matrix multiplication is not commutative which means that the result of A*B is not equal to the result of B*A which suggests that the order does matter in matrix multiplication.
AB ≠ BA
Real-world Example:
We can model a set of equations that will represent the number of games won by each team.
Let x represents team Brazil and y represents team Spain.
2x + 3y = 12
6x + 8y = 34
In the matrix form
When we solve this matrix we get x = 3 and and y = 2
Which means that Brazil has won 3 games and Spain has won 2 games.
Now if you change the order of these variables then you wont get the correct results and this is exactly why matrix multiplication is not commutative because the order is important in matrix multiplication.
