Answer:
16.23
Step-by-step explanation:
Use cosine to solve.
cos = adjacent / hypotenuse
cos 52 = 10 / x
(x = AB)
(cos 52)(x) = 10
x = 10 / (cos52)
x = 10 / 0.616
x = 16.2338
AB = 16.23
The answer is X=-.75 (the line between -1 and -.5) and Y=-1, I hope this helps!
The circumference of a circle is 2(3.14)r, and if 8.5 * 2 is 17, the answer will be 17*3.14.
An estimate is 51, and the actual answer is 53.38.
Answer:
i = -2
Step-by-step explanation:
1: Simplify both sides of the equation -2 = -2i-6
2: Flip the equation -2i-6=-2
3: Add 6 to both sides -2i-6+6=-2+6
4: Divide both sides by -2 -2i/-2 = 4/-2
5: Answer is i = -2
The product of the matrices is an identity matrix. Then Both the matrices are multiplicative inverse to each other.
<h3>What is the matrix?</h3>
A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The a_{ij} element in a matrix, such as M, refers to the i-th row and j-th column element.
The matrices are given below.
![\left[\begin{array}{ccc}-3&7\\-2&5\end{array}\right] \ and \ \left[\begin{array}{ccc}-5&7\\-2&3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-3%267%5C%5C-2%265%5Cend%7Barray%7D%5Cright%5D%20%5C%20%20and%20%5C%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-5%267%5C%5C-2%263%5Cend%7Barray%7D%5Cright%5D)
Then show that both the matrices are multiplicative inverse to each other.
If the product of the matrices is an identity matrix then the matrices are multiplicative inverse to each other.
Then we have
![\left[\begin{array}{ccc}-3&7\\-2&5\end{array}\right] \left[\begin{array}{ccc}-5&7\\-2&3\end{array}\right] = \left[\begin{array}{ccc}1&0\\0&1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-3%267%5C%5C-2%265%5Cend%7Barray%7D%5Cright%5D%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-5%267%5C%5C-2%263%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%5C%5C0%261%5Cend%7Barray%7D%5Cright%5D)
Then both the matrices are multiplicative inverse to each other.
