equation of the line that passes through the points (0,6) and (-3,2)?
Answer:
Step-by-step explanation:
y=mx+b is the general equation of a line, where
m= slope = (y2-y1)/(x2-x1)= (6-2)/(0- -3)= 4/3
b= y intercept
for point (0,6)
y=(4/3)x+b will become 6=(4/3)*0 +b, so b=6
the equation of the line that passes trough the given points is
y= (4/3) x +6
Answer:
y = 4/3 x + 6
Step-by-step explanation:
M = -4/-3 = 2/3
y = 4/3 X + B
6 = 4/3(0) + B
B=6

Answer:
Step-by-step explanation:
The candle is cylindrical in shape.
The formula for determining the volume of a cylinder is expressed as as
Volume = πr²h
Where
π = 3.14
r represents radius of the cylinder and also the candle
h represents the height of the cylinder and also the candle.
Looking at the diagram,
r = 4 cm
h = 6 cm
Volume of candle = 3.14 × 4² × 6
= 301.44 cm³
Looking at the table,
60 cm³ of the candle melts off in 2 hours, it means that the in one hour, the volume of candle that melts off would be 60/2 = 30cm³
Therefore, in 7 hours, the volume of candle that would melt off is
30 × 7 = 210 cm³
Therefore, the percent of candle that is melted off after 7 hours would be
210/301.44 × 100 = 69.67%
Approximately 70% to the nearest percent.
Answer:
After 7 hours about 70% of the candle was melted
