h=70 cm
r=15 cm
[volume of a cone]=pi*15²*70/3----------> 16485 cm³

If 7+5i is a zero of a polynomial function of degree 5 with coefficients, then so is _.

defon

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 $z=a+ib$ is a root of a polynomial with degree 'n' , then the conjugate of the complex number ( $\overline{z}=a-ib$ ) 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 ( $\overline{7+5i}=7-5i$ ) 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 function f(x) represents the time it takes an airplane to travel east. The function g(x) represents the time it takes an air

tensa zangetsu [6.8K]

The total time taken for round trip will be: (f+g)(x) = 14x+11

Step-by-step explanation:

Given

$f(x) = 4x+13\\g(x) = 10x-2$

In order to find the round-trip time, we have to add both functions to represent the time taken to travel east and the time taken to travel to west.

$(f+g)(x) = f(x)+g(x)\\= (4x+13)+(10x-2)\\=4x+13+10x-2\\=4x+10x+13-2\\=14x+11$

Hence,

The total time taken for round trip will be: (f+g)(x) = 14x+11
