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:
6
Step-by-step explanation:
U have to subtract the 2 numbers.
The bigger number is 1,787 * 10^9
the smaller is 8,867*10^8
Now convert the bigger to the same power of 10
1,787 * 10^9 = 17,87 * 10^8
17,87 * 10^8 - 8,867*10^8 = 9,003 * 10^8
8km=5miles
1miles= 5/8=0.625mile
100km = 100x0.625=63.5 miles
Answer:
In the figure attached, the solution is shown.
Step-by-step explanation:
Given the inequality:
|x| < 3
There are 2 solutions:
x < 3 or x > -3
This can be rewritten as follows:
-3 < x < 3
On the number line, this represents all the point between -3 and 3. Notice that -3 and 3 are not included in the solution; that is why there are open circles at these points on the graph.
