Answer:
(√6)/2 square units
Step-by-step explanation:
The area of a triangle is half the magnitude of the cross product of the vectors representing adjacent sides.
QR = (4-3, -1-(-4), -4-(-5)) = (1, 3, 1)
QS = (3 -3, -5-(-4), -6-(-5)) = (0, -1, -1)
The cross product is the determinant ...
The magnitude of this is ...
|QR × QS| = √((-2)² +1² +(-1)²) = √6
The area of the triangle is half this value:
Area = (1/2)√6 . . . . square units
Answer:
21
Step-by-step explanation:
subtract 3t from both sides
multiply both sides by 3
so 6t = -21
Answer:
10 units
Step-by-step explanation:
We are given two points on a plane;
(7 , -2) and (7 , 8)
We are supposed to determine the distance between the two points;
- To get the distance between two points on a plane, we should use modulus formula;
- Modulus =
Therefore, in this case;
Distance =
Therefore, the distance between the two points is 10 units.
