Answer:
D)4x + 6/(x + 1)(x - 1)
Step-by-step explanation:
A field is basically a rectangle, so to find the perimeter of our field we are using the formula for the perimeter of a rectangle
where
is the perimeter
is the length
is the width
We know from our problem that the field has length 2/x + 1 and width 5/x^2 -1, so 
and 
.
Replacing values:
Notice that the denominator of the second fraction is a difference of squares, so we can factor it using the formula 
where 
is the first term and 
is the second term. We can infer that 
and 
. So, 
. Replacing that:
We can see that the common denominator of our fractions is 
. Now we can simplify our fraction using the common denominator:
We can conclude that the perimeter of the field is D)4x + 6/(x + 1)(x - 1).
F and K are definitely outliers of the plot
Answer:
B. 14 ft approx
Step-by-step explanation:
Given data
A teepee has a conical shape
Diameter= 10ft
radius= 5 ft
Volume = 366ft³
Height = ????
The expression for the volume is
V= 1/3πr^2 h
substitute
366= 1/3*3.142*5^2*h
366= 1/3*78.55*h
366= 26.18h
h= 366/26.18
h=13.98 ft
h= 14 ft approx
Hence the Height is 14 ft approx
