Answer:
d =
Step-by-step explanation:
Given that W varies jointly as L and d² then the equation relating them is
W = kLd² ← k is the constant of variation
To find k use the condition W = 140 when d = 4 and L = 54, thus
140 = k × 54 × 4² = 864k ( divide both sides by 864 )
= k , that is
k =
W = Ld² ← equation of variation
Multiply both sides by 216
216W = 35Ld² ( divide both sides by 35L )
= d² ( take the square root of both sides )
d =
Answer:
POSTULATE
Step-by-step explanation:
<em>A postulate is a statement that is assumed true without proof. A theorem is a true statement that can be proven </em>
<em> </em>
<em> </em>
<em> </em>
<em>In geometry, the theorem is considered valid or correct with which its assertion is practically not refuted by almost anyone, whether it is really true or not. </em>
<em> </em>
<em> </em>
<em> </em>
<em>This, in practice, implies that all students of the subject share the same criteria on the theory. Thus, the postulates, in short, have the following characteristics: </em>
<em> </em>
<em> They are presumed true by most of the scholars in the field. </em>
<em> </em>
<em>Its contradiction goes against the very essence of the subject. </em>
<em> </em>
<em>Postulate 6: If two planes intersect, then their intersection is a line.</em>

<em>See Attachment for Details ^^</em>
<em>The image attached represents the statement given in the question (If two distinct planes intersect, then their intersection is a line)</em>
<em>Therefore</em><em>, </em>
<em> </em>
<em>The Geometry term that represents the statement above is POSTULATE</em>
