It’s hard to see! Please let me know the numbers on the graph
1 ) cot x * sin x = cos x
(cos x / sin x) * sin x = cos x
cos x = cos x
Answer: B ) cot x = cos x / sin x
2 ) ( sin² x + cos² x ) / cos x = sec x
1/cos x = sec x
sec x = sec x
Answer: C ) cos² x + sin² x = 1
Answer:
M(4, -3)
Step-by-step explanation:
Reflecting over the x-axis is simple:
If the x is positive, the reflection would be negative and vice versa.
In this case, the <em>y </em>isn't affected since it's only reflecting over the x-axis.
So, M is at the coordinates (4, -3)
The radius of a circle is
always half of the diameter of the circle. In this case, the diameter is
, meaning that when we halve
, we will get our radius. Therefore, the radius of the circle is
. Hope this has helped you understand and have a great day!
