Answer:

(x - 5) ^2 + (y -2)^2 = 1

Step-by-step explanation:

This is for a circle.

We need to complete the square

(x^2 -10x ) + ( y^2 -4y ) = -28

(x^2 - 10x +25) + (y^2 - 4y 2y) = -28 + 25 + 4

(x-5)^2 + (y-2)^2 = 1

The center of this circle would be (5,2) with a radius of 1.

$f'(x)=\dfrac{4x}{1+7x^2}$

Integrating gives

$f(x)=\displaystyle\int\frac{4x}{1+7x^2}\,\mathrm dx$

To compute the integral, substitute $u=1+7x^2$ , so that $\frac27\,\mathrm du=4x\,\mathrm dx$ . Then

$f(x)=\displaystyle\frac27\int\frac{\mathrm du}u=\frac27\ln|u|+C$

Since $u=1+7x^2>0$ for all $x$ , we can drop the absolute value, so we end up with

$f(x)=\dfrac27\ln(1+7x^2)+C$

Given that $f(0)=10$ , we have

$10=\dfrac27\ln1+C\implies C=10$

so that

$\boxed{f(x)=\dfrac27\ln(1+7x^2)+10}$

ANSWER

Step 3

EXPLANATION

The given polynomial expression is:

$2 {p}^{2} - 3p - 7 - (3 {p}^{2} + p - 5)$

Fatau correctly expanded the parenthesis in the first step.

$2 {p}^{2} - 3p - 7 - 3 {p}^{2} - p + 5$

Fatau also correctly grouped the like terms to obtain:

$(2- 3) {p}^{2} + (- 3 - 1)p + (- 7 + 5)$

Fatau committed a mistake at the third step.

Instead of obtaining,

$- {p}^{2} - 4p - 2$

He mistakenly got:

${p}^{2} - 2p +2$
