I am not sure about this but here goes nothing: d=2.5t+2.2 is very familiar to y=mx+b y=d m=2.5 x=t b=2.2 to find a new quasion we substitute d and t into place wich equals 1=2.5(0)+b simplification and you get b=1 so your answer is d=2.5t+1
Answer:
Irrational
Step-by-step explanation:
When we take the square root of both sides, we get z = 0.141421... and since there are no fractions and the decimals go endlessly on, it is irrational.

Step-by-step explanation:
The answer is D.
Answer: 
<u>Step-by-step explanation:</u>
Use the decay formula: 
where
- P is the remaining amount of the sample
- P₀ is the original amount of the sample
- k is the decay rate
- t is the time (in hours)
Given: P = 44.5, P₀ = 356, k = unknown, t = 210 minutes (3.5 hours)
Input P₀ = 356 and k = -0.59413 into the decay formula
