Answer:
A. CB
Step-by-step explanation:
3 x 2 (C is a 3 by 2) matrix can be multiplied to a 2 x 2 (B is a 2 by 2) matrix since C has 2 columns that are equal to the number of rows in the second matrix B.
A way of checking if two matrices can be multiplied is to first check the number of columns the first matrix contains and then check the number of rows that the second matrix contains.
If the number of columns in the first matrix equal the number of rows in the second matrix then that means it is possible to multiply these matrices.
We need to find the maximum (Vertex of the function)
Let:
L = Length = 1500 - 2x
W = Width = x
The area is given by:
We can find the maximum using the following formula:
Evaluate the area for the value we found previously:
The largest area that can be enclosed is 281250m²
Answer:
1/4
Step-by-step explanation:
coins have 2 sides, tails and heads, so for it to land on tails is a 1/2 chance. Dice have 6 sides and 1,3,5 are all odd so its a 3/6 chance. Simplify 3/6 to 1/2 and multiply by 1/2 to get 1/4. im not sure, its my guess.
Answer: If Tom finished the race in 95 seconds and Robert finished 20 seconds before Tom, Robert finished in 75 seconds.
The expression that shows this is 95-20=75.
46-(-26)
= 46+26
= 72
As - and - together makes plus.
