Answer:
It would take 10 days to completely empty the rain gauge.
Step-by-step explanation:
Initial reading of rain gauge = 10 inches
<u>Every day rain evaporated by 2 inches but 1 more inch of rain was added.</u>
<u>In effect, only one inch of rain water evaporated that is everyday level decreased with 1 inch.</u>
After the end of day 1 , the reading would show 9 inches and 8 inches at the end of day 2 and similarly reading decreases linearly.
Since the reading should decrease by 10 inches it would take 10 days to completely empty the rain gauge.
In this question, we have to write the set of points from -6 to 3 but excluding -2 and 3 as a union of intervals .
For union, we use U.
For the points that we have to exclude , we put parenthesis on there side that is ().
Therefore the required interval form is
As we see that () are used with -2 and 3 . And that's the required interval form .
Answer:
yes, parallelogram ABCD is a square.
Step-by-step explanation:
Given information: ABCD is parallelogram with vertices A(0,4), B(2, 2), C(4,4), and D(2,6).
We need to check whether this parallelogram is a square or not.
The opposite side of a parallelogram are parallel and congruent. If the interior angles a parallelogram are right angles then the parallelogram is square.
Formula for slope:
Now, find the slopes of each side.
The product of slopes of two perpendicular line is -1.
The product of slopes of any two consecutive sides is -1. It means all interior angles are right angle.
Therefore, the parallelogram ABCD is a square.
