Given directed line segment PR below, find the coordinates of Q on PR

g100num [7]

Answer:

$(\frac{4}{3},-3)$

Step-by-step explanation:

The location of a point O(x, y) which divides line segment AB in the ratio a:b with point A at ( $x_1,y_1$ ) and B( $x_2,y_2$ ) is given by the formula:

$x=\frac{a}{a+b}(x_2-x_1)+x_1\\ \\y=\frac{a}{a+b}(y_2-y_1)+y_1$

From the graph, the location of the point is P(2, 5), R(1, -7). Let point Q be (x, y) which divides PR in ratio 2:1. Coordinates of point Q is at:

$x=\frac{a}{a+b}(x_2-x_1)+x_1=\frac{2}{2+1}(1-2)+2=\frac{2}{3}(-1)+2=\frac{4}{3} \\ \\y=\frac{a}{a+b}(y_2-y_1)+y_1=\frac{2}{2+1}(-7-5)+5= \frac{2}{3}(-12)+5=-3$

Point Q is at $(\frac{4}{3},-3)$

Hey ASAPPP PLS 80 points

Klio2033 [76]

Answer:

using pythagoras theorem

a^2+b^2=c^2

8^2+x^2=(x+2)^2

64+x^2=x^2+2*x*2+2^2

64+x^2=x^2+4x+4(here x^2 of left hand side and x^2 of right hand side gets cancel)

64=4x+4

64-4=4x

60/4=x

15=x

Please help asap!!! NO WRONG ANSWERS PLS

4vir4ik [10]

Answer:

$= 41.4 {cm}^{2}$

Step-by-step explanation:

<h2><em><u>First</u></em><em><u> </u></em><em><u>case</u></em><em><u>:</u></em></h2>

Sides of a square = 3 cm

Therefore, area of the square = <em>side × side</em>

= 3cm × 3cm

$= 9 {cm}^{2}$

<h2><em><u>Second</u></em><em><u> </u></em><em><u>c</u></em><em><u>ase</u></em><em><u>:</u></em></h2>

Radius of the circle = 4cm

Therefore, area of the circle

$= \pi {r}^{2}$

$= 3.15 \times 4cm \times 4cm$

$= 50.4 {cm}^{2}$

<h2><em><u>Last</u></em><em><u> </u></em><em><u>case</u></em><em><u>:</u></em></h2>

Area of the shaded region

= <em>Area</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>circle</em><em> </em><em>-</em><em> </em><em>Area</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>square</em><em> </em>

$= (50.4 - 9) {cm}^{2}$

$= 41.4 {cm}^{2} (ans)$
