Answer: 7.3
Step-by-step explanation:
To find the distance between these two points, find the difference in the x and y values then square them and add them then finally find the square root of that added number obtained.
5 - 7 = -2
9 - 2 = -7
-2^2 + -7^2 = d^2 where d is the distance
4 + 49 = d^2
53 = d^2
d =
d= 7.2801 rounded to the nearest tenth is 7.3
If one solution is -3-5i then the other solution will be -3+5i
So, Option A is correct.
Step-by-step explanation:
We need to find the other solution of the quadratic function, when one solution is -3-5i
The quadratic equation is of the form:
The complex roots of the quadratic equation are of form:
So, if one solution is -3-5i then the other solution will be -3+5i
So, Option A is correct.
