Answer: A

I believe the correct answer would be A:  Accurate. A reflection will change the direction the vertices trace around the figure. A rotation preserves the change.

Hoped this helped :D

State whether the triangles are similar. If so, write a similarity statement and the postulate or theorem you used.
ratelena [41]
I believe the triangles are not similar. In order for the triangles to be similar, they would either need one more set of sides or angles to be congruent, but they only have one set of angles and one set of sides congruent. I am not entirely sure I am correct

In an AP, the 8th term is equal to the sum of the first 8<br> terms. Show that the 4th term is 0
dimulka [17.4K]

Answer:

let the first term of an A.P. is 'a' and common difference 'd'

∴ 8th term = sum of the first 8 terms

a8 = S

a + 7d = 8/2(2a + (8 - 1)d)

a + 7d = 8/2(2a + 7d)

2a + 14d = 16a + 56d

16a + 56d - (2a + 14d) = 0

14a + 52d = 0

divide eq. by 14 we get  ,

a + 3d = 0

and a + 3d = a4  = 0

For what value of c is the relation a function (2,8),(12,3),(c,4),(-1,8),(0,3)
Fittoniya [83]
The value of c is { c | c ∈ R, c ∉ {-1,0,2,12} }.
c is a number such that it is not in the set {-1,0,2,12} else we end up with a domain value having multiple range values, contradicting with the definition of a function.

How do you do this problem?
faust18 [17]

The volume of the original cylinder is

... V = π·r²·h

For r=1 and h=1, this is

... V = π·1²·1 = π

For the new cylinder, the volume is 1.089 times that amount.

... V = 1.089π = π·1.1²·(1-k)

... 1.089/1.21 = 1-k

... k = 1 - 1.089/1.21 = 1 - 0.9 = 0.1 = 10%

The appropriate choice is (B) 10.
