Answer: (-2,-5)
Step-by-step explanation:
The rotation rule for rotating a figure about is given by :-
, where (x,y) is the coordinates for pre-image and (y,-x) is the coordinates for image. (1)
Given : The coordinates of LMN are L (4,5), M (5,-2), and N (0,0).
If the triangle is rotated 270° about point N
Then, the coordinates of M , will be :
(Using the rule described in (1))
Hence, the coordinates of M after rotated 270° about point N=(-2,-5).
Answer:
b > 12.71
Step-by-step explanation:
Here in this question we have to solve the inequality equation given for b (An unknown variable}
Now, the equation is
⇒
We are taking the base of the log here is 10.
So, {Since
and
}
⇒ b > 12.71 (Approximate) (Answer)
