Answer:

19.41 units

Step-by-step explanation:

<u>Given coordinates of points;</u>

(-10, 9)
(-6, -10)

To determine the distance between the two points, the distance formula is required. The distance formula is used where it is not possible to calculate the distance through a straight line. The distance formula is expressed as,

⇒ $\sqrt{(x_{2} - x_{1})^{2} + (y_2 - y_1)^{2} }$

The distance between the two points can be determined by plugging the coordinates into the formula;

⇒ $\sqrt{(x_{2} - x_{1})^{2} + (y_2 - y_1)^{2} }$
⇒ $\sqrt{[-6 - (-10)]^{2} + [-10 - 9]^{2} }$

Then, we can simplify the root as needed to determine the distance;

⇒ $\sqrt{[-6 + 10]^{2} + [-19]^{2} }$
⇒ $\sqrt{[4]^{2} +361 }$
⇒ $\sqrt{16 +361 }$
⇒ $\sqrt{377}$

Finally, we need to convert the root into decimals (stated in question). It is impossible to determine the root in decimal form. Therefore, I used a calculator to determine the distance in decimal form.

⇒ $\sqrt{377}$ ≈ 19.41 units [Using calculator]

Therefore, the distance between the two points is about 19.41 units.

Using the Distance Formula and the Pythagorean Theorem, find the distance, to the nearest tenth, from F

Fantom [35]

Answer:

Step-by-step explanation:

$d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\(3,2)\quad\implies\quad x_1=3\,,\ \ y_1=2\\\\(-5,-2)\quad\implies\quad x_2=-5\,,\ \ y_2=-2\\\\d=\sqrt{(3+5)^2+(2+2)^2}=\sqrt{8^2+4^2}=\sqrt{64+16}=\sqrt{80}\approx8.9$

Write a real-world problem involving a percent greater than 100%. Then solve the problem.

Mrrafil [7]

There are two extra credit questions on the Biology test, and 27 questions overall [including the afore-mentioned two]. If Jo answers all questions [including the extra credits] correctly, and each is worth the same amount, what score does she earn?

Answer: 108%

27 − 2 = 25. 100 / 25 = 4. So, each question is worth 4%. 2 x 4% = 8% That’s how much the extra credit is worth. 100% (main test) + 8% (extra credit) = 108% (best score possible).
