Answer:
(0, ±2√5)
Step-by-step explanation:
The foci are the points on the major axis that are the length of the semimajor axis away from the co-vertices.
Here, that means their y-coordinate is ±√(36-16) = ±√20 = ±2√5.
The x-coordinate is that of the major axis, x=0.
Answer:
Step-by-step explanation:
Complex numbers identity:
The complex numbers identity is:
Square of the sum:
In this question:
So
Answer:
(x + y)1 - a)
Step-by-step explanation:
x + y - ax - ay
= x - ax + y - ay
= x(1 - a) + y(1 - a)
= (x + y)1 - a)
First we find the slope of the given line by using slope intercept form.
Converting the equation into slope intercept form
Divide both side by 5 we get
On comparing with
We get slope
as the slope of line is negative therefore the line will either "b" or "d"
As line "b" pass from (0,2)
On putting it in given equation we get
Which is not equL to RHS of the line
Therefore b is not the given line
Now putting point (0,-2)
We get
Satisfy the equation and line "d" pass from it
There the give equationis of line "d"
Answer:
3√2
Step-by-step explanation:
In this question, we are asked to get the value of √ ( x²-y² ), while the value of x² and y² are given to be 33 and 15 respectively.
Hence, x² =33 and y² = 15.
Putting the values of x² and y² in the above expression we get,
√ ( x²-y² ) = √ ( 33-15) = √18 =3√2. (Answer)
