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 area of the garden would be 192 square feet. When you divide the area of his backyard by the side known, you find the missing side. The missing side is 24, which means that is the other leg of the triangle. By using the area formula for a right triangle you find the answer.
Answer:
181 ft^2
Step-by-step explanation:
A of wall=10*23=230
A of door=7*3=21
A of window=((4+3)/2)*4=7/2*4=28/2=14
theres two windows so 14*2=28
230-21-28=230-49=181 ft^2
You can change mm into cm. Since 1 cm is equal to 100 mm, divide 500 by 100 to get 5 cm. Add 30 and 5 to get 35. The two line segments are 35 cm together.
Answer:
3 - 2√5
-------------
2
Step-by-step explanation:
These two expressions have different denominators, and thus use of the LCD is necessary. The LCD is 4.
Thus, we have:
6/4 - (4/4)√5, or
6 - 4√5
