1. the image is multiplied by the scale factor. if the scale factor is 2, the image is twice the size of the preimage. if the scale factor is ⅓, the image is one third the size. only a scale factor of 1 preserves congruency
4500 is the answer to this question.
Answer:
A
Step-by-step explanation:
90 degree angle = right angle, that's what it is. you know there's 60 degree, so the other one is 90 - 60 = 30. since it's 3 times x, it's 10.
Answer:
Step-by-step explanation:
First lets fill in the variables
Now solve
3 - 9 = -6
2 - -1 = 3
-6/3 = -2
The first term of GP, a=4
Common ratio=
=
=-5
r=-5
nth term of GP, an=a
a8=4*
a8=4*
a8=4*-78125
a8=-312500
