Domain is x values... Y is y values
Answer:
at first : circumference = 25.12 = pi*d--------> d= 25.12/ pi
after one minute: circumference = 75.63= pi*d-------> d= 75.63/pi
Step-by-step explanation:
A) minute 1) diameter = 7.995946004446154 mm
minute 2) diameter = 24.07378170048816 mm
(I'll assume that you can round if necessary)
B) The diameter of the new ink spot is roughly 3X larger
(technically 3.01074841 X larger)
Answer:
Step-by-step explanation:
Let the equation of the line 'a' is,
y = mx + c
Here, m = slope of the line
c = y-intercept
For line 'a',
Slope of the line =
m =
m =
y-intercept = 20
Therefore, equation of the line 'a' is,
y =
Similarly, equation of the line 'b' is,
y = m'x + c'
Slope of the line =
m' =
m' =
y-intercept = 0
Therefore, equation of the line is 'b' is,
y =
1). Line 'b' represents a proportional relationship → FALSE
2). The constant of proportionality of y to x for line 'a' is → FALSE
3). The ratio of y-coordinate to x-coordinate of one of the points on line b is 25 : 8 → FALSE
4). let a passes through the point so the constant of proportionality is → TRUE
