Answer:
my best guess would be H
Step-by-step explanation:
3.3 x 3.3 = 9.9 which is close to 10
For this case we have an equation of the form:
y = A (b) ^ t
Where,
A: initial amount
b: decrease rate
t: time
Substituting values:
y = 750 (0.5) ^ ((1/15) * t)
The number of days to reach 68 mg is:
68 = 750 (0.5) ^ ((1/15) * t)
Clearing t:
(0.5) ^ ((1/15) * t) = (68/750)
log0.5 ((0.5) ^ ((1/15) * t)) = log0.5 (68/750)
(1/15) * t = log0.5 (68/750)
t = 15 * log0.5 (68/750)
t = 51.94
Rounding:
t = 52 days
Answer:
D. ≈ 52 days
Answer:
21

Answer:
f(x) = -4
Step-by-step explanation:
Given function: f(x) = 4 + 4x - 4x²
Here, we are being asked to find the value of the function when x is equal to 2.
Substitute 2 as the value of x in the function and simplify:
⇒ f(x) = 4 + 4x - 4x²
⇒ f(2) = 4 + 4(2) - 4(2)²
⇒ f(2) = 4 + 8 - 4(4)
⇒ f(2) = 4 + 8 - 16
⇒ f(2) = 12 - 16
⇒ f(2) = -4
This means that when the value of x is 2, the value of the function is -4.
