Answer:
Step-by-step explanation:
No, as 15 + -5 OR 15 - 5 is not 5, it is 10.
Hope that helps!
Answer:
I think the ans is
=Square root(my keyboard doesn't have the square root) b^2+(-c+a)^2
Step-by-step explanation:
So the point of Q, 0 is the x1, -a is the y1, point P, b is the x2, while -c is y2.
So, you just sub the points of Q and P in the distance formula, then you will find it
The sequence is arithmetic as it goes down 3 every time
Arithmetic nth term formula is an=a1+d(n-1)
an=7-3(n-1)
an=7-3n+3
an=-3n+10
To find the 100th term substitute n for 100
a100=-3(100)+10
a100=-300+10
a100=-290
The 100th term is -290
Answer:
None of the options are correct.
Step-by-step explanation:
Let the complex number is a + ib
Given distance from origin = 17 units
Now, by distance formula distance of a point from the origin =
1) <u>Check for 2 + 15 i</u>
here, 
≠ 17
2)<u> Check for 17 + i</u>
here, 
≠ 17
3)<u> Check for 20 - 3 i</u>
here, 
≠ 17
4) <u>Check for 4 - i</u>
here, 
≠ 17
Hence, none of the options are correct.
