Answer:
second supporting point=?
Answer:
166.6 joules
Step-by-step explanation:
The formular for potential energy is Mgh
Mass is 8.5 kg
g = acceleration due to gravity (9.8)
height is 2 meters
= 8.5 × 9.8 × 2
= 166.6 joules
Hence the potential energy is 166.6 joules
Answer:
The solution to the quadratic equation:
Step-by-step explanation:
Given the equation
6x - 0.2x · x = 0
Factor out common term -x
-x (0.2x - 6) = 0
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
solving
Multiply both sides by 10
Refine
Add 60 to both sides
Simplify
Divide both sides by 2
Simplify
Thus, the solution to the quadratic equation:
Since yz is the tangent
angle zyx=90
by pyth. theorem
15 ²=4 ²+ZY ²
ZY=c
