Answer:
-37.
Step-by-step explanation:
a2 = 2 a2-1 - 3
= 2 a1 - 3
= 2*-2 -3
= -7
a3 = 2 a3 - 3
= 2*-7 - 3
= -17
4th term a4
= 2*-17 - 3
= -37.
Answer:
d = 8.602325
Rounded = 9
For:
(X1, Y1) = (1, 4)
(X2, Y2) = (6, -3)
Answer:
2+√3
Step-by-step explanation:
We know that roots with square roots come in pairs
so if we have a+ sqrt(b), we will also have a - sqrt(b)
Since one of the roots is 2 -sqrt(3), it must have another root of 2+ sqrt(3)
Answer:
5 km
Step-by-step explanation:
We are given the distances walked by Maria;
We are required to determine the displacement from her starting point;
- We are going to use Pythagoras's theorem;
a² + b² = c²
Taking, the distances towards south and towards west as the legs of the triangle;
Then, c² = 3² + 4²
= 25
c = √25
= 5 km
Therefore, the displacement from the starting point is 5 km
