Slope-10 pass through (2,-5)

ahrayia [7]

Slope = -10
<span>pass through (2,-5)
y = mx + b
so
b = y - mx
b = -6 - (-10) (2)
b = -6 + 20
b = 14

equation
y = -10x + 14</span>

Someone help me plsh

Klio2033 [76]

Answer:

See attached image

Step-by-step explanation:

With this type of reflection, one has to convert the points of the form (x, y) into (y, x).

So the vertices of the triangle will transform the following way:

(4, 4) into image (4, 4)

(4, 1) into image (1, 4)

(2, 1) into image (1, 2)

Please see attached picture to find the new reflected triangle depicted in red.

HELP ASAP PLEASE

Stels [109]

Solution (1) using angles of sectors:

Area of A = pi r^2 x 90/360 = 4.9

Area of B = pi r^2 x 270/360 = 14.2

Check: Area of A/B = 4.9/14.72 = 1/3 (as given)

Solution (2) using given info:

Area of B + Area of A = area of circle

Area of B + 1/3 Area of B = 3.14 * (2.5)^2 = 19.625

4/3 Area of B = 19.625

Area of B = 3/4 * 19.625

Area of B = 14.72

Area of A = 1/3 * 14.72 = 4.9

There is more solutions to this problem , like polar coordinate integration , and so on. for more just request.
