Determine the coordinate of the 4th point
From the given parameters, we can see that the rectangle is either horizontal or vertical.
This is because:

and

To calculate the fourth point, we simply make use of:
and 
Substitute 1.5 for x2 in 


Substitute -2 1/2 for y3 in 


Hence, the 4th point is:

Answer with Step-by-step explanation:
We are given that displacement of wave

Where y in cm and t in sec.
a.Compare it with

Amplitude of wave=A
We get A=1.5
Amplitude=A=1.5 cm
b.k=0.68


Using 
Wavelength of the wave=9.2 cm
c.Period=


The period of the wave=0.17 s
Speed of the wave=
Speed of the wave=54.1 cm/s
Hi mate!
The answer after simplifying is: 2x^2-6x+7

The value of the modulus function |-3| is 3.
<h3>What is the value of modulus?</h3>
'Modulus' exists a Latin word, which signifies 'measure'. Absolute value is commonly referred to as numeric value or magnitude. The absolute value designates only the numeric value and does not contain the sign of the numeric value. The modulus of any vector quantity exists ever taken as positive and exists in its absolute value.
The absolute value (or modulus) | x | of a real number x stands as the non-negative value of x without regard to its sign.
For example, the absolute value of 5 stands at 5, and the absolute value of −5 exists also at 5. The absolute value of a number may be considered as its distance from zero along a real number line.
Therefore, the value of the modulus function |-3| is 3.
