1 answer:
Answer:
She travel 6.6 ft/sec
Step-by-step explanation:
Jenna runs 5 miles everyday.
She averages 4.5 miles per hour
Now we are supposed to find How many ft/sec does she travel
1 mile =5280 feet
1 hour = 3600 seconds
Now convert the given speed in feet per second using conversion
So, speed in feet/sec=
So, speed in feet/sec=6.6 ft/sec
So, She travel 6.6 ft/sec

Answer:
is perpendicular to
and parallel to
Step-by-step explanation:
First, convert the equation to standard form so that y is isolated.
x + 5y = 6 --> x - 6 = -5y (divide both sides by -5) -->
A perpendicular line will have a slope that is the opposite reciprocal of the original slope (meaning you flip the numerator and denominator then make it negative).
is perpendicular to
which simplifies to 5.
A parallel line will have the same slope, but the y-intercept will be different. It can be pretty much any number as long as the original slope is used in the new equation.
is parallel to
just like
