Answer:
<h2>Step-by-step explanation:
To find y when x=4, we must first find the relationship between them
The statement
y varies directly with x is written as
<h3>where k is the constant of proportionality
From the question
when y = 1/5
x = 3
Substitute the values into the above formula and solve
That's
<h3>So the formula for the variation is
<h3>From the question
when x = 4
<h3>Hope this helps you
The volume of a prsm is given by the area of the base multiplied by the height.
Given a <span>pentagonal prism with a perpendicular distance of 14 units between the bases and a volume of 840 cubic units. This means that the height of the prism is 14 units.
i.e. Area of base x 14 = 840
which implies that the area of the base = 840 / 14 = 60
Assuming that the pentagonal base is regular.
Area of the pentagon base is given by
where a is the length of the sides.
Perimeter of a pentagon is given by 5a
where a is the length of the sides.
Therefore,. the perimeter of the base of the pentagonal prism is given by 5 x 5.9054 = 29.5 units.
