Answer:
Cos C = adjecent/hypotenuse
Cos C = 14/50
divide the numerator and the denominator by 2
Cos C = 7/25
The answer is C
Answer:
Step 1 is incorrect because it was mutiplied. Instead, you should divide.
Step-by-step explanation:
Answer:
4). (x + 2)^2 + (y - 1)^2 = 25.
Step-by-step explanation:
x^2 + y^2 + 4x - 2y - 20 = 0
x^2 + 4x + y^2 - 2y = 20
Completing the square on the x and y terms:
(x + 2)^2 - 4 + (y - 1)^2 - 1 = 20
(x + 2)^2 + (y - 1)^2 = 20 + 4 + 1
(x + 2)^2 + (y - 1)^2 = 25.
Answer: 74
Step-by-step explanation:
nth term= 6n+2 (work out the nth term)
6x12+2=74 (substitute 12 in (to find the 12th term))
12th term= 74
