- Quadrilateral ABCD has vertices at A(-3,-4), B(-1, -1), C(2,-2), and
D(3,-4). Graph quadrilateral ABCD and
its image after a 180° counterclockwise
rotation about vertex D. Then give the
coordinates of the vertices of the image.

The average human heart beats 1.15 \cdot 10^51.15⋅10 5 1, point, 15, dot, 10, start superscript, 5, end superscript times per day. there are 3.65 \cdot 10^23.65⋅10 2 3, point, 65, dot, 10, start superscript, 2, end superscript days in one year.how many times does the heart beat in one year? write your answer in scientific notation, and round to one decimal place.
