3+(2)(6)+63
Answer:
60% decrease
Step-by-step explanation:
150/100(%)=1.5
60/1.5=40(%)
100(%)-40(%)=60(%)
Answer:
Step-by-step explanation:
To answer all the parts given find the equation of the line given in the graph.
Let the equation is,
y = mx + b
m = slope of the line
b = y-intercept
x = time
y = Amount of water
Slope of a line passing through two points
and
is,
m = 
Slope of the given line passing through (0, 80) and (1, 320)
m = 
m = 240
Y-intercept 'b' = 80
Therefore, y = 240x + 80 will be the equation.
a). At x = 0
y = 240(0) + 80
y = 80 liters
b). As the time is increasing amount of the water is increasing
Rate of increase in the water = Slope of the line
= 240 liters per minute
This just wants the derivative which you can solve for.
You can do this using a negative expononet or using ...the rational rule forget its name*.... you shoudl get 9000/(t+12)^2
*Quotient rule
