Answer:△DEF is congruent to △D′E′F′ because the rules represent a translation followed by a reflection, which is a sequence of rigid motions.
Step-by-step explanation:
A rigid motion of the plane is a motion which maintain distance.
Translation is a kind of rigid motion used in geometry to trace a function that moves an object a particular distance.
A reflection is also a kind of rigid motion . It is mainly a 'toss' of a shape across the line of reflection.
So,△DEF is mapped to △D′E′F′ using the rule (x,y)→(x,y+1) ( which is a translation.) followed by (x,y)→(x,−y)(which is reflection),therefore it is a sequence of rigid motions.
Work = force * distance
1800 ft-lb = force * 15 ft
force = 1800 ft-lb / 15 ft
= 1800/15 ft-lb/ft
= 120 lbs
Answer:
24
Step-by-step explanation:
41-17=24
I think the answer is 128. Hope it helps!
Answer:
Step-by-step explanation:
May we see the whole picture, but if you are confident in the numbers but not the placement this should help you!
(x,y)
The x-intercept would be the first number so (x,y)
And the y-intercept would be the second number (x,y)
Hope this helps ya! Keep smiling!
