Answer:
The parabola generated by the expression :
is the one that better represents a rain gauge above the ground.
Step-by-step explanation:
The function:
a)
Direction of parabola: branches pointing up
Location of vertex relative to x-axis: below
So, the parabola doesn't depict a rain gauge off the ground
b)
Direction of parabola: branches pointing down
Location of vertex relative to x-axis: above
So, the parabola doesn't depict a rain gauge off the ground
c)
Direction of parabola: branches pointing up
Location of vertex relative to x-axis: two units above
So, the parabola depicts a rain gauge off the ground
d)
Direction of parabola: branches pointing up
Location of vertex relative to x-axis: right on the x-axis
So, the parabola doesn't depict a rain gauge off the ground (this is sitting on the ground)
e)
Direction of parabola: branches pointing up
Location of vertex relative to x-axis: below
So, the parabola doesn't depict a rain gauge off the ground
Answer:
Step-by-step explanation:
To solve this B needs to be isolated. First we must multiply both sides of the equation by 2 to get rid of the fraction on the left side. Next, divide both sides by h to get rid of the h on the left side. Finally, subtract b form both sides to get B by itself.
