Answer:
y=-3x+80
Step-by-step explanation:
Points (12,44) and (20,20)
slope = -3
Equation of line: y - 44 = -3(x - 12)
Answer: 35 m
Step-by-step explanation:
The problem is the same as:
a man is fix (not moving) and the goods train is travelling at the speed of 54+72 = 126 (km/h)
Distance = 126 km/h* 8 s=126000 m/(3600 s) * 8 s=35 m
The centroid is found by intersecting the medians of a triangle
Answer: Choice B
This is something to memorize or have on a reference sheet
Side notes:
1) The altitudes cross to form the orthocenter
2) The perpendicular bisectors intersect at the circumcenter
3) The angle bisectors intersect at the incenter
Answer:
1050 ft
Step-by-step explanation:
Each tick mark apparently represents a distance of 700/10 = 70 ft. Then the 7+8 = 15 tick marks separating Anaad and Cala represent ...
... 15 × 70 ft = 1050 ft
