Answer:
5
Step-by-step explanation:
Find the greatest common divisor:
gcd(20, 45, 15)
Find the divisors of each integer and select the largest element they have in common:
The divisors of 20 are:
1, 2, 4, 5, 10, 20
The divisors of 45 are:
1, 3, 5, 9, 15, 45
The divisors of 15 are:
1, 3, 5, 15
The largest number common to all divisor lists is 5:
divisors of 20: 1, 2, 4, 5, 10, 20
divisors of 45: 1, 3, 5, 9, 15, 45
divisors of 15: 1, 3, 5, 15
Answer: gcd(20, 45, 15) = 5
I= sqrt (-1)
If the power is
- even then the value could be -1 or 1
-odd then the value could be -i or i
99 is odd so now is
-i if (99+1)/2 is even or is
i is (99+1)/2 is odd
Now check (99+1)/2= 100/2= 50,
50 is even so
i^99 = -i
Answer:

Step-by-step explanation:
It is given that circle is a tangent to y axis, which tells us that the distance between the centre point and y axis is the radius of the triangle.
Formula for equation of circle with centre (x1,y1) and radius r is

In the given case distance between the centre and y axis is 7 units so radius would be 7 and the centre point is (-7,2),
the equation of circle is ,


Hence the abow equation is the circle equation.
