Step-by-step explanation:
multiply y by 9: 9y
then divide 10 by the result: 10/(9y)
Decay every two years over a period of t years:
Fourth option: f(t)=(0.75)^(t/2)
decay 2 times a year over a period of t years:
Second option: f(t)=(0.9306)^(2t)
Sixth option: f(t)=(0.8660)^(2t)
decay once per year over a period of t years:
First option: f(t)=(0.9306)^t
Third option: f(t)=(0.8660)^t
Answer: x=40

Answer:
Step-by-step explanation:
Coordinates of point B = (8, -6)
<u>Reflection across the x-axis results in:</u>
<u>Coordinates of B'</u>
- (8, -6) → (8, -(-6)) = (8, 6)
