Reflection is when the pre-image is flipped over a line.
By knowing that <em>water</em> outflow is <em>stable</em> and the known geometry, the <em>draining</em> time of the rectangular tank is equal to a time of a minute and 36 seconds.
<h3>How to determine the draining time of a rectangular tank</h3>
In this question we must determine the <em>draining</em> time of a tank whose dimensions are known and whose <em>water</em> outflow is <em>stable</em>. The <em>draining</em> time is equal to the volume of the <em>rectangular</em> tank divided by <em>outflow</em> rate:
V = (1.2 m) · (0.8 m) · (0.5 m)/(0.3 m³/min)
V = 1.6 min
By knowing that <em>water</em> outflow is <em>stable</em> and the known geometry, the <em>draining</em> time of the rectangular tank is equal to a time of a minute and 36 seconds.

Answer:
her grandson would be 7 and her granddaughter would be 5.
Step-by-step explanation:
their ages together is 12. we divide that by the two grandchildren, and adjust it to where they are to years apart.
12÷2=6
6+6 + adjusted = 5 and 7.
to fact check 5+7=12, and 7 is two numbers above 5.
10kg's is greater than 18,000
18,000 < 10kg
The directrix of the parabola is
<h3>How to determine the equation of the directrix?</h3>
The parabola equation is given as:
A parabola is represented as:
By comparing both equations, we have:
4p = 1/4 ==> p = 1/16
-k= 3 ==> k = -3
The directrix is represented as:
y = k - p
So, we have:
Take the LCM
Evaluate
Hence, the directrix of the parabola is
