B-2.5mph You divide 10 (how far you went) by 4 (the amount of time it took you) which gives you 2.5 (the amount of time it takes you to walk 1 mile) To check: It takes you 2.5 hours to walk 1 mile so multipling 2.5 by 4 tells you how far you walked in 4 hours
Answer:
215 ft
Step-by-step explanation:
The length of the surrounding fence is equal to the perimeter of the garden. That is the sum of the lengths of the straight sides and the curved arc. The arc length is given by the formula ...
s = r·θ . . . . . where θ is the central angle in radians
__
<h3>arc length</h3>
There are π radians in 180°, so the arc will have a measure in radians of ...
θ = 132° × (π/180°) = 11/15π ≈ 2.3038 . . . . radians
Then the length of the curved side of the garden is ...
s = (50 ft)(2.3038 radian) ≈ 115.2 ft
__
<h3>perimeter</h3>
The fence length is the sum of the arc length and the two radii:
perimeter = 115.2 ft + 2×50 ft = 215.2 ft
About 215 feet of fencing are needed to enclose the garden.
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have to, if two lines are parallel then their slopes are equal.
If we have with slope , then a parallel line will have slope
Thus, the equation of the parallel line is of the form:
We substitute the given point and find "b":
Finally, the equation is:
