Answer:
Proof:
By the inscribed angle theorem, we know that angle BAC is equal to angle DEC. By the second corollary to the inscribed angle theorem, we know that line segment AE is perpendicular to line segment AC. Therefore, line segment AE is tangent to circle C.
Step-by-step explanation:
Analyze and ensure the answer is correct.
Answer:

Step-by-step explanation:

Substitute x = 2 and y = -4 into 
2⁻² = 
2⁻³ = 
-4⁵ = -1024
×
× -1024 = -32
Okay a,b,c don't make sense at all. but if I had to choose I'd go with A and B since the exact numbers are used
The first question is the 3rd choice.
The second question is also the 3rd choice.
