Ab has vertices at (–5, 1) and (–3, 7). after a transformation, the image had endpoints at (3, –1) and (5, 5). describe the transformation.

a.
translation right 2 units and up 6 units
b.
rotation 90° about the origin
c.
translation right 8 units and down 2 units
d.
reflection across the y-axis

We can solve this by comparing up points of first and second line and down points of first and second line.

When doing so we can see that x value of is increased by 8 on second line than on first line and we can also not that y coordinate is decreased by 2 on second line.

That means the answer is C) it is shifted 8 to right and 2 to down.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
