Write an equation in standard form of the line that passes through (3, 1) and has a y intercept of -2

aleksandr82 [10.1K]

Step-by-step explanation:

First of all, use substitution to find slope

(1) = m(3) - 2

3 = m3

m = 1

With both the slope and y int, you can write it in y int form

y = 1x - 2

Convert that to standard form

-x + y = -2

There is a rectangle ABCD, with sides AB = CD = 32, and sides and BC = DA = 24. The rectangle is rotated 90° clockwise about C,

Sphinxa [80]

Answer

given,

side of rectangle, AB = CD = 32

BC = DA = 24

rectangle is rotated 90° clockwise about C.

then rotated 90° clockwise about D.

Path traveled by the point A for first rotation will be in circle with radius AC.

$D_1 = \dfrac{\theta_1}{360^0}\times \pi \times {AC}^2$

$AC = \sqrt{24^2+32^2}$

AC = 40

θ₁ = 90°

$D_1 = \dfrac{90^0}{360^0}\times \pi \times {40}^2$

D₁ = 1256.64

For the second rotation Point A will move in circular path with radius of AD

$D_2 = \dfrac{\theta_2}{360^0}\pi {AD}^2$

AD = 24

θ₁ = 90°

$D_2 = \dfrac{90^0}{360^0}\times \pi \times {24}^2$

D₂ = 452.39

total path traveled by the point A

D = D₁ + D₂

D = 1256.64 + 452.39

D = 1709.03
