Answer:
-3 i hope this helps :)
Step-by-step explanation:
(4,7) (7,-2)
x1 y1 x2 y2
<u>-2 - 7 </u> = <u>-9</u> = -3
7 - 4 3
<span>3 X squareroot (10 X 100) =
3X (10) X squareroot (10) =
[ where the squareroot of 100 is 10]
30 X squareroot (10) =
30 X squareroot (2 X 5) =
[where the squareroot of 2 is 1.414]
30 X (1.414) X squareroot (5) = 94.85</span>
Answer:
61 degrees
Step-by-step explanation:
add A and C and subtract 180 by the sum
If complex coefficients are allowed, the answer is 3.
If the polynomial must have real coefficients, then each complex root comes as a pair of complex conjugate roots.
Root -5 is real, so that is 1 root, and degree 1.
Root 1 + 4i is complex, so it must come with its complex conjugate, 1 - 4i. This adds 2 roots to the polynomial, and now we're up to degree 3.
Root -4i is also complex. It also must come with its complex conjugate, 4i. That adds two more roots, and the degree is 5.
Answer: The least possible degree is 5 with real coefficients.
