19. x^2+16x+64
=(x+8)^2
21. x^2-10x+25
=(x-5)^2
Answer:
Explanation:
• The initial dose of the Insulin = 10 Units
The insulin breaks down by about 5% each minute, therefore:
• The decay rate, r= 5%
We want to determine the time it will take for the remaining dosage to be half (5 units) of the original dose.
We use the exponential decay function:
Substituting the given values, we have:
To solve for t, we change to logarithm form.
