Answer:
(x, y ) → (- y, - x )
Step-by-step explanation:
Consider the coordinates of corresponding vertices of the 2 triangles, that is
A(1, 7 ) → D(- 7, - 1 )
Note the coordinates of D are the negative reversals of A
Thus (x, y ) → (- y, - x )
Write and solve the appropriate exponential equation:
228 = 16(r)^4, where r is the change per hour in the number of bacteria:
228
------ = r^4 = 14.25.
16
Taking the fourth root of both sides, we get: r = 1.94 (answer)
-2.7639320225 is the exact when estimated -3 hope this helped if can pls mark as brainliest have a great day!
Answer:
15 feet
Step-by-step explanation:
Perimeter = All outside lengths added together
We know that the shape is a square, and squares have 4 sides.
So, divide 60 by 4.
60 / 4 = 15.
The length of one side is 15 feet.
