Question 12(Multiple Choice Worth 1 points)
salantis [7]

The statement which would best describe the line segments drawn in relation to one another is " They are parallel and congruent " ⇒ 3rd answer

Step-by-step explanation:

In a translation,

  • Every point of the object must be moved in the same direction.
  • Every point of the object must be moved for the same distance.
  • The lines drawn from each point to its image are parallel and congruent.

The rules of translation:

  • If the point (x , y) translated horizontally to the right by h units  then its image is (x + h , y)
  • If the point (x , y) translated horizontally to the left by h units  then its image is (x - h , y)
  • If the point (x , y) translated vertically up by k units  then its image is (x , y + k)
  • If the point (x , y) translated vertically down by k units  then its image is (x , y - k)

∵ Δ JOY is translated using the rule (x, y) → (x + 3, y - 2)

∵ Δ J'O'Y' is its image after translation

- That means each point move 3 units to right and 2 units town

∵ Line segment JJ' joins the vertex J by its image J'

∵ Line segment OO' joins the vertex O by its image O'

- The lines drawn from each point to its image are parallel

   and congruent

∴ JJ' // OO'

∴ JJ' ≅ OO'

The statement which would best describe the line segments drawn in relation to one another is " They are parallel and congruent "

Find the equation of a line tangent to the circle (x−1)^2+y^2=26 at the point (2, −5).
77julia77 [94]

Center of circle is ( 1, 0).

Slope of normal passing though ( 1, 0 ) and ( 2, -5 ) is :

m_p=\dfrac{0-(-5)}{1-2}\\\\m_p=-5

So, slope of tangent will be :

m_t=-\dfrac{1}{m_n}\\\\m_t=\dfrac{1}{5}

Equation of tangent :

y-(-5)=\dfrac{1}{5}(x-2)\\\\5y+25=x-2\\\\5y-x+27=0

Hence, this is the required solution.
