It's a nonlinear because the x and y values are not increasing at the same ratio each time. This would be an example of a linear function:
x l 1 2 3 4 5 6
y l 3 6 9 12 15 18
As x increases by 1, y increases by a multiple of 3

B dependent, 36/15625
Step-by-step explanation:
Answer:
39 cm
Step-by-step explanation:
Given
ΔABC and ΔA'B'C'
B = 5 cm
B' = 15 cm
Perimeter ΔABC = 13 cm
Required
Determine the perimeter of ΔA'B'C
[Since ΔABC is dilated to give ΔA'B'C', the first step is to get the scale factor.]
Scale Factor = ΔA'B'C ÷ ΔABC
[Using side B and B' as points of reference]
Scale Factor = B' ÷ B
[Substitute values for B' and B]
Scale Factor = 15 ÷ 5
Scale Factor = 3
[The perimeter of ΔA'B'C' is then calculated as:]
Perimeter ΔA'B'C'= Scale Factor * Perimeter of ΔABC
ΔA'B'C = 3 * 13 cm
ΔA'B'C = 39 cm
Answer:
y = 3x-10
Step-by-step explanation:
The slope intercept form of a line
y = mx+b where m is the slope and b is the y intercept
The slope is 3 and the y intercept is -10
y = 3x-10
Answer:
2pi/C = 45/360
Step-by-step explanation:
L = arc length
C = circumference
x = central angle
Tying those three variables together leads us to this
L = (x/360)*C
The idea is we effectively take a fraction of the circumference to end up with the arc length.
In the formula above, we can rearrange terms to get
L = (x/360)*C
360L = Cx
L/C = x/360
We know that L = 2pi and x = 45, which means we end up with
L/C = x/360
2pi/C = 45/360
