$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's find the Radius ~

$\qquad \sf \dashrightarrow \: area = \frac{ \theta}{360} \times \pi {r}^{2}$

$\qquad \sf \dashrightarrow \: 80= \frac{ 72}{360} \times \pi {r}^{2}$

$\qquad \sf \dashrightarrow \: {r}^{2} = \frac{80 \times 360}{72 \times \pi}$

$\qquad \sf \dashrightarrow \: {r}^{2} = \frac{80 \times 5}{ \pi}$

$\qquad \sf \dashrightarrow \: {r}^{} = \sqrt\frac{400}{ \pi}$

$\qquad \sf \dashrightarrow \:r = \frac{20}{ \sqrt{\pi} }$

$\qquad \sf \dashrightarrow \:r \approx 11.28 \: ft$

I hope you understood the whole procedure, let me know if you have doubts ~

Using the Pythagorean

miss Akunina [59]

Answer:

13.5 units

Step-by-step explanation:

<u>Use distance formula:</u>

$d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

<u>Substitute the coordinates:</u>

$d = \sqrt{(-3-7)^2+(-3-6)^2} =\sqrt{10^2+9^2} =\sqrt{181} =13.5$ rounded

A student solves the following equation and determines that the solution is −2. Is the student correct? Explain. 3 a + 2 − 6a a2

Ganezh [65]

For this case, we have the following equation (according to the comments):

$\frac{3}{a+2} - \frac{6a}{a^2-4} = \frac{1}{a-2}$

First, we factor the quadratic expression in the denominator:

$\frac{3}{a+2} - \frac{6a}{(a-2)(a+2)} = \frac{1}{a-2}$

Then, we multiply both sides of the equation by (a-2) (a + 2):

$\frac{3(a-2)(a+2)}{a+2} - \frac{6a(a-2)(a+2)}{(a-2)(a+2)} = \frac{(a-2)(a+2)}{a-2}$

Later, canceling similar terms we have:

$3(a-2) - 6a = a+2$

We do distributive property on the left side of the equation:

$3a-6-6a=a+2$

By grouping variables and constant terms we have:

$3a - 6a -a = 2+6$

Rewriting we have:

$-4a=8$

Finally, by clearing "a" we have:

$a=-\frac{8}{4} a=-2$

Note: the value of a is a extraneous solution because it makes the denominator of the original equation equal to zero.

Answer:

the student correct, but the value of a= -2 is an extraneous solution
