Answer:
y = 4x + 3
Step-by-step explanation:
The output of 3 at x = 0 tells you the y-intercept is 3.
The change of 4 from 3 to 7 for an input change of 1 from 0 to 1 tells you the slope is 4/1 = 4. Then the slope-intercept form of the equation is ...
y = mx + b . . . . . m = slope, b = y-intercept
y = 4x + 3
_____
It is pretty conventional to use y for the output variable and x for the input variable. Your rule could be ...
output = 4 × input + 3
I think it will be 30. 10×3=30
Answer:
Step-by-step explanation:
Radius r = 12.5/2 = 6.25 cm
Height h = 7 cm
volume = πr²h = 3.14⋅6.25²⋅7= 858.6 cubic cm
