Step-by-step explanation:
write the one digit in the square of each of the following numbers
a.13
Sin = opposite/hypotenuse
so sin (x) = 12/13
answer is 12/13
Answer:
D
Step-by-step explanation:
Given
x² - 10x = - 36
Solve using the method of completing the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(- 5)x + 25 = - 36 + 25
(x - 5)² = - 11 ( take the square root of both sides )
x - 5 = ±
( add 5 to both sides )
x = 5 ± i
Thus
x = 5 - i
or x = 5 + i
The answer should be A.not entirely sure though
Hope this helps
