If the domain of the coordinate transformation (, ) = ( + 2,− − 4) is (1, -4), (3, -2), (0, −1), what is the range?

timama [110]

Answer:

A. (-2, -5), (0, -7), (1, -4)

Step-by-step explanation:

The following transformation is applied:

$(x,y) \rightarrow (y + 2, -x - 4)$

To find the range:

We apply the transformation to the points in the domain. Thus:

$(1,-4) \rightarrow (-4 + 2, -1 - 4) = (-2, -5)$

$(3,-2) \rightarrow (-2 + 2, -3 - 4) = (0, -7)$

$(0,-1) \rightarrow (-1 + 2, 0 - 4) = (1, -4)$

Thus the correct answer is given by option a.

A road sign is in the shape of a regular heptagon. What is the measure of each angle on the sign? Round to the nearest tenth.

lisabon 2012 [21]

<span><u>Answer </u>
A) 〖128.6〗^o

<u>Explanation </u>
The question requires us to find the interior angle of a regular heptagon.
To do this first calculate the exterior angle of that polygon.
The sum of exterior angles is 360o. A heptagon has 7 sides.
So, one exterior angle = 〖360〗^o/7=〖51.4〗^o
interior angle+exterior angle=〖180〗^o
exterior=180-51.4=〖128.6〗^o
