Complete Question
A certain 50 cm spring will stretch (in cm) one fifth the weight (in kg) attached to it. How long will the spring be if a 35 kg weight is attached to it
Answer:
The value is
Step-by-step explanation:
The length of the spring is
The mass attached to it is
Generally given from that the spring will stretch one fifth of the weight (in kg)attached to it , it then means that the new length of the spring whenever a weight is attached to it is mathematically represented as

Answer:
f(x) = 8x + 15
f(-7)=8*(-7)+15=-56+15=-41
Let point Q = (4,y)
√[ (4-0)^2 + (y-0)^2 ] = √[ (6-0)^2 + (0-0)^2 ]
Square both side
(4-0)^2 + (y-0)^2 = (6-0)^2 + (0-0)^2
4^2 + y^2 = 6^2
16 + y^2 = 36
y^2 = 36-16
y^2 = 20
y= √20
y= 2√5
