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>.

Answer:
The train travels at 120 miles per hour.
Step-by-step explanation:
All we have to do is divide 540 by 4.5
540 ÷ 4.5 = 120
So the answer is 120 miles per hour.
Hope this helps! :)
The length and width might be 6ft and 2ft because you have 6+6+2+2=16ft for the perimeter and 6x2=12sqft for the area
