Answer:
AB=18cm
Step-by-step explanation:
sabendo que sin∅=0.6 então
0.6=AB/30cm ⇒ AB=0.6*30cm ⇒ AB=18cm
Step-by-step explanation:
The answer is OPTION C
Find the Inverse of a 3x3 Matrix.
First
Find the Determinant of A(The coefficients of e
Proceed towards finding the CO FACTOR of the 3x3 Matrix.
+. - +
A= [ 1 -1 -1 ]
[ -1 2 3 ]
[ 1 1 4 ]
The determinant of this is 1.
Find the co factor
| 2 3 | |-1 3 | |-1 2 |
| 1. 4. | |1 4 | |1. 1 |
|-1. -1 | |1 -1 | |1 -1
| 1. 4 | |1. 4| |1 1|
|-1. -1 | |1 -1 | |1. -1
|2. 3| |-1. 3| |-1 2|
After Evaluating The Determinant of each 2x 2 Matrix
You'll have
[ 5 7 -3]
[3 5 -2 ]
[-1 -2 1]
Reflect this along the diagonal( Keep 5,5 -2)
Then switching positions of other value
No need of Multiplying by the determinant because its value is 1 from calculation.
After this
Our Inverse Matrix Would be
[ 5 3 -1 ]
[7 5 -2 ]
[ -3 -2 1]
THIS IS OUR INVERSE.
SO
OPTION C
Answer:
8 < 6x
Step-by-step explanation:
Just write what you see by the letters
Your solution My solution
8p (>/=) -7 8p >/= -7
8p/8 (=) -7/8 <span>8p/8 </span>>/= -7/8
<span>p (=) -7/8 </span><span>p </span>>/= <span> -7/8</span>
The last two equation only has the equal "=" sign. The greater than ">" sign was removed.
Greater than ">" sign should not be removed because the expression is an inequality.
Inequality expressions deal with numerous numbers that can make the inequality true.
Putting only an equal sign will limit the number option into 1. It will only make half of the inequality true. P = -7/8 but it is not > -7/8.
The answer is k = -18/5 and in decimal form its -3.6.
5k/-3 + 4 = 10
5k/-3 = 10 - 4
5k/-3 = 6
-5k = 6 * 3
-5k = 18
k = 18/-5.
