Answer:
The equation of the line is y - 16 = 3(x - 3)
Step-by-step explanation:
To find the equation of this line, we first need to find the slope. To do that, we use the slope equation.
m(slope) = (y2 - y1)/(x2 - x1)
m = (16 - 4)/(3 - -1)
m = (16 - 4)/(3 + 1)
m = 12/4
m = 3
Now that we have the slope, we can use it and either point in point-slope form.
y - y1 = m(x - x1)
y - 16 = 3(x - 3)
The slope is rise over run
The rise is 1
The run is 2
So the slope would be 1/2
If the function is:
y=a cos( bx+c), or y=a sin(x+c)
then the period is T= 2π/b and if T=2:
2=2π/b
b=2π/2=π
Answer: B) y=3 cos πx
It would take the faucet 18 hours to fill the tank because 18/12=1.5. That means it will be 1.5 times slower to fill the tank up with the hose on. 1.5*12=18.
