If we look at our values for X and Y in the example problem, we see that we have -2 and 8. If X is -2, then 8 is 10 digits larger than -2. So, if X is 0, Y is 10.
The answer is b hope that helps
It switch to the buzzer app so is 8 + 2 equals what I could be 8 x 2 equals what times that equals what
Answer:
B
Step-by-step explanation:
The exponential decay formula is
y= ab^x
where a is the initial value and
b = 1- decay rate
b= .9
.9 = 1 - decay rate
Subtract 1 from each side
.9-1 = 1-1-decay rate
-.1 = -decay rate
Multiply by -1
.1 = decay rate
Change to a percent
10 % = decay rate
A.) For 25 ≤ d ≤ 150;
ΔT/Δd = (5.50 - 5.50)/(150 - 25) = 0/125 = 0
b.) For 25 ≤ d ≤ 75;
ΔT/Δd = (5.10 - 5.50)/(75 - 25) = -0.4/50 = -0.008
c.) For 100 ≤ d ≤ 200;
ΔT/Δd = (6.00 - 5.10)/(200 - 100) = 0.9/100 = 0.009
