Answer: No. You cannot multiply the matrices in any order. A*B is not defined. Also, B*A is not defined.
------------------------------------------------------------------------
Explanation:
Matrix A has 1 row, and 4 columns.
Matrix B has 3 rows, and 4 columns
In order for A*B to be possible, A has to have the same number as columns as B has rows. In other words, the inner dimensions have to match up. The '4' in '1x4' needs to match up with the '3' in the '3x4'. This match doesn't happen.
The same story happens with B*A, just things have been flipped.
B has 3 rows, 4 columns
A has 1 row, 4 columns
The "4 columns" of B does not match with "1 row" of A.
Answer:
4.66
Step-by-step explanation:
Cause 4 would be 4.0 and then you take 100 and divide by the denominator and you get .33 for every 1/3. Since you have 2/3 it would be .66, then your answer would be 4.66
Answer:
6
Step-by-step explanation:
divide both sides of the equals by 5 to get p on its own
5p divided by 5 = p
30 divided by 5 = 6
The boat's travel from when it was first noticed until it stopped is 554.89 ft.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
A person is watching a boat from the top of a lighthouse. The boat is approaching the lighthouse directly.
From the given information we can draw a right-angle triangle.
14°52' = 14 + 0.86 = 14.86 degree
45°10' = 45 + 0.16 = 45.16 degree
In the right-angle triangle ACD
tan14.86 = 200/AC
AC = 753.772 ft
In the right-angle triangle DBC:
tan45.16 = 200/CB
CB = 198.886 ft
AB = AC - CB
AB = 753.772 ft - 198.886 ft
AB = 554.886 ≈ 554.89 ft
Thus, the boat's travel from when it was first noticed until it stopped is 554.89 ft.
