Answer:
Step-by-step explanation:
Sin A Cos B + Cos A Sin B = Sin (A +B)
Sin 10 cos 50 + Cos 10 Sin 50 = Sin (10 + 50) = Sin 60 = √3/2
Answer:
- 
Step-by-step explanation:
Given the 2 by 2 matrix
![\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da%26b%5C%5Cc%26d%5C%5C%5Cend%7Barray%7D%5Cright%5D)
The determinant = ad - bc
For the given matrix
a = , b = 
, c = , d = , thus
ad - bc = × - ( × ) = 
- 
= -
Answer:
204/100 = 51/25= 2 1/25 that is the answer
Answer:
4
Step-by-step explanation
The highest degree of a quadratic equation or polynomial always determine the number of factors or zeros that such polynomial have.'
For the polynomial 2x^4+6x-5
You can see that the leading degree is 4. Hence the polynomial will have 4 roots and factors
Answer:
t = 50
Step-by-step explanation:
EI = EG
2t - 79 = t - 29
t - 79 = -29
t = 50
