Bacteria begins to grow on the water's surface in a non-operational swimming pool on September 20. The bacteria grows and covers
the water's
surface in such a way that the area covered with bacteria doubles every day. If it continues to grow in this way, the water's surface will be
entirely covered with bacteria on September 28.
When will a quarter of the water's surface be covered?
O A.
The water's surface will be covered a quarter of the way on September 24.
B.
The water's surface will be covered a quarter of the way on September 26.
C.
The water's surface will be covered a quarter of the way on September 27.
OD. The water's surface will be covered a quarter of the way on September 25.

Given:
The point is T(-3,7).
To find:
The image T' after .
Solution:
, it means reflection across x-axis is followed by reflection across y-axis.
If a point is reflected across the x-axis, then
Then point is reflected across the y-axis. So,
Therefore, the coordinates of point T' are (3,-7).
Answer:
The triangle is an obtuse scalene triangle
Step-by-step explanation:
we know that
if --------> is a right triangle
if --------> is an obtuse triangle
if --------> is an acute triangle
where
c is the greater side
we have
so
so
-------> is an obtuse triangle
Remember that
The given triangle has three different length side
so
Is a scalene triangle
therefore
The triangle is an obtuse scalene triangle
