Use calculus to find the area a of the triangle with the given vertices. (0, 0), (6, 2), (4, 8)

Vilka [71]

The area of the triangle with vertices $(x_1,y_1),(x_2,y_2),(x_3,y_3)$ is

$\frac{1}{2}\left|\begin{array}{ccc}1&x_1&y_1\\1&x_2&y_2\\1&x_3&y_3\end{array}\right|$ .

Inserting numerical values, the are of the triangle with vertices (0, 0), (6, 2), (4, 8) is

$\Delta = \frac{1}{2}\left|\begin{array}{ccc}1&0&0\\1&6&2\\1&4&8\end{array}\right |\\
\Delta = 0.5(48-8)\\
\Delta = 20 \;square\; units$

Points (−3, 5) and (3, 5) on the coordinate grid below show the positions of two players on a tennis court:

Anna35 [415]

Answer:

4. Player 2's position is Player 1's position reflected across the y-axis; only the signs of the x-coordinates of Player 1 and Player 2 are different.

Step-by-step explanation:

Player 1's position is (-3, 5).

It means that it is 3 units left from the origin and 5 units above the origin.

Player 2's position is (3, 5).

It means that it is 3 units right from the origin and 5 units above the origin.

Hence, the two points are on the same horizontal line bisected by the y-axis.

So, Player 2's position is Player 1's position reflected across the y-axis; only the signs of the x-coordinates of Player 1 and Player 2 are different.

In the attachement, there is what I came up with so far. I think that finding 'a' is non-trivial, if possible at all.

$A_c$ - the area of a circle

$A_{cs}$ - the area of a circular segment

Find the value of y.

olga nikolaevna [1]

Try this option:
1. the sides of the biggest triangle are 16; x and √(16²-x²); the sides of the smallest triange are x;5 and y. The smallest triangle ~ the biggest triangle. Using the property of the similar triangles:
$\frac{x}{5} = \frac{16}{x}, \ then \ x= \sqrt{80}$
2. according to the Pyphagorean theorem (in the smallest triangle):
$y= \sqrt{ \sqrt{80^2} -5^2} = \sqrt{55}$

answer: y=√55.
