Answer:

Step-by-step explanation:

[tex]\Delta C=2\pi(r_2-r_1)\\ \\ \Delta C=2\pi(6400001-6400000)\\ \\ \Delta C=2\pi\\ \\ \Delta C\approx 6.283m\\ \\ \text{So taking off 6 meters is reasonable.}[/tex}

What is the domain of the function?Rotate the image to see it.

sergey [27]

Answer:

answer B is correct

Step-by-step explanation:

Hello,

this is not allowed to divide by 0 so we need to find the zeros of

$x^2+2x-15=0$

$x^2-3x+5x-15=0\\ x(x-3)+5(x-3)=0\\ (x+5)(x-3)=0\\ x=-5 \ \ or \ \ x=3$

we need x different from -5 and from 3

answer B is correct

hope this helps

Which of the number(s) below are potential roots of the function? p(x) = x4 + 22x2 – 16x – 12

Neporo4naja [7]

Complete question is;

Which of the number(s) below are potential roots of the function? p(x) = x⁴ + 22x² – 16x – 12

A) ±6

B) ±1

C) ±3

D) ±8

Answer:

Options A, B & C: ±6, ±1, ±3

Step-by-step explanation:

We are given the polynomial;

p(x) = x⁴ + 22x² – 16x – 12

Now, the potential roots will be all the rational numbers equivalent of p/q.

Where;

p are the factors of the constant term of the polynomial

q are the factors of the leading coefficient of the polynomial

Now, in the given polynomial, the constant term is seen as -12 while leading coefficient is 1 which is the coefficient of x⁴.

We know that factors of 12 are any of:

±1, ±2, ±3, ±4, ±6 and ±12

While possible factors of 1 is just ±1.

Thus, all the potential roots of the polynomial function are;

±1, ±2, ±3, ±4, ±6 and ±12

From the options given, option A, B & C could be the potential roots.
