Answer: If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is <u>its conjugate 7-i5</u>.
Step-by-step explanation:
- We know that when a complex number
is a root of a polynomial with degree 'n' , then the conjugate of the complex number (
) is also a root of the same polynomial.
Given: 7+5i is a zero of a polynomial function of degree 5 with coefficients
Here, 7+5i is a complex number.
So, it conjugate (
) is also a zero of a polynomial function.
Hence, if 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is <u>its conjugate 7-i5</u>.
The only rational root is -2.336071261738453
The other roots are complex (imaginary).

×22
=124
+1240
=1364
her answer is not responsible because how can 124+1240=1,042
Answer:
m /_ 1 is the same as m /_ 4 because they are vertical angels which equals to 35 degrees.
aince g and i are parallel :
m /_ 4 must equal m/_ 12 because they are exterior angels.
So the answer is 35 degrees
