Answer: Speed in miles per hour is 45 mph.
Step-by-step explanation:
Since we have given that
Distance covered = 15 miles
Time taken to cover the above mentioned distance = 20 minutes
We need to calculate the speed in miles per hour ,
As we know the formula for " Speed " i.e.
Now, we will put the value of distance and time in the above formula:
Hence, Speed in miles per hour is 45 mph.
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
