What is the distance between (5, 9), (−7, −7)?

Licemer1 [7]

Answer:

Step-by-step explanation:

Use the distance formula to determine the distance between the two points.

$\text{Distance}=\sqrt{(x_2=x_1)^2+(y_2-y1)^2}$

Substitute the actual values of the points into the distance formula.

$\sqrt{((-7)-5)^2+((-7)-9)^2}$

Simplify.

⇒ Subtract 5 from 7.

$\sqrt{(-12)^2+((-7)-9)^2}$

⇒ Raise -12 to the power of 2.

$\sqrt{144+((-7)-9)^2}$

⇒ Subtract 9 from -7.

$\sqrt{144+(-16)^2}$

⇒ Raise -16 to the power of 2.

$\sqrt{144+256}$

⇒ Add 144 and 256.

$\sqrt{400}$

⇒ Rewrite 400 as 20².

$\sqrt{20^2}$

⇒ Pull terms out from under the radical, assuming positive real numbers.

Describe the error Sadie made, and explain how to find the correct answer. (Refer to image)

ki77a [65]

1. Sadie should note that $54a^7b^3\ge 0$ and if $a\ge 0$ , then $b\ge 0$ .

2. While simplifying Sadie makes some mistakes (it must be $3^2$ instead of $3^3$ and she missed the sign of absolute value for b). The right way to find the correct answer is:

$\sqrt{54a^7b^3}=\sqrt{3^2\cdot 6\cdot a^2\cdot a^5\cdot b^2\cdot b} =3\cdot a\cdot |b| \sqrt{6\cdot a^5\cdot b}=3ab\sqrt{6a^5b}$ .

3. The simpliest expression is $3ab\sqrt{6a^5b} =3ab\sqrt{6\cdot a^2\cdot a^2\cdot a\cdot b} =3a^3b\sqrt{6ab}$ .
