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.
Answer:
The correct option is C.
Step-by-step explanation:
It is given that the point F is the center of the circle and the points A, B, C, D, and E are on the circle.
A line segment joining any point on the circumference to the center of the circle is known as radius of the circle.
Since F is the center of the circle and the points A, B, C, D, and E are on the circle, therefore the line segments FA, FB, FC, FD and FE radius of the circle F.
So, option C is correct.
Answer:
If it's meant to be 2.1875*10^-3 then your answer would be 36571428.
If it's 2.1875*10-3 then your answer would be 4238.
Step-by-step explanation:
By dividing the weight of the whale by the weight of the krill you get your answer.
A = bh
b = 16
h = 3
A = 16*3
A = 48 square centimenters
Answer:
Because 20 has to be doubled to become 40. While 40 is twice as much as 20 so you just divide 40 by 20 to get 50%.
Explanation:
20 x 20 = 40 = 100%
40 / 20 = 50%
