Answer: x=4.23606797749979 y=0.23606797749979
Step-by-step explanation:
Let the two numbers be x and y
As given, the difference of two numbers is 3, so
or
....(1)
And their sum is 25, so
.....(2)
Putting x=3+y in equation (2)



As, x+y=25


So the two numbers are = 14 and 11
Answer:
2; 5; 8
Step-by-step explanation:
To fill in the table, we need to generate an equation to represent the relationship between x and y.
First, find the slope using the two pairs given, (5, -1) and (25, 11):

m = ⅗.
Next, using the point-slope form, we can use a point/coordinate pair and the slope to derive an equation as follows.

Where,

m = ⅗.
Plug in the values



Subtract 1 from both sides


Use the equation above to fill out the table by plugging each value of x into the equation to get the corresponding values of y for each x value.

Step-by-step explanation:
<u>Root Of Complex Numbers</u>
If a complex number is expressed in polar form as

Then the cubic roots of Z are
![\displaystyle Z_1=\left(\sqrt[3]{r},\frac{\theta}{3}\right)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20Z_1%3D%5Cleft%28%5Csqrt%5B3%5D%7Br%7D%2C%5Cfrac%7B%5Ctheta%7D%7B3%7D%5Cright%29)

We are given the complex number in rectangular components

Converting to polar form


It's located in the second quadrant, so

The number if polar form is
