<span>The rule (x,y)→(2x,2y) maping △DEF to △D′E′F′ is a dilation which enlarges the pre-image by a scale of 2.
Two triangle are congruent when all the corresponding angles are equal and all the corresponding sides are equal.
Therefore, </span>t<span>he triangles are not congruent because △D′E′F′ is a dilation of △DEF , and a dilation is not a rigid motion.</span>
Answer:
The 3 one
Step-by-step explanation:
Given:
u varies directly with the square of p and inversely with d.
To find:
The equation for the given situation.
Solution:
If y is directly proportional to x, then
If y is inversely proportional to x, then
It is given that u varies directly with the square of p and inversely with d. So,
It can be written as:
Where, k is the constant of proportionality.
Therefore, the required equation is .
