.2 goes into 7 35 times.
you move the decimal in .2 to make it 2 and make 7 70; 2 goes into 7 3 times which gives you 6 on top and 10 on the bottom, 2 goes into ten 5 times so your final answer would be 35
Using an exponential function, it is found that the multiplier used to predict the amount of medication remaining 2 hours after the peak level is of 0.6889.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, we have that the decay rate is of r = 0.17, hence:

After 2 hours, the multiplier is given by:

Answer:
Yes it has
Step-by-step explanation:
From my perspective.........
f(x) = -4(x + 3)² - 5
f(x) = -4(x + 3)(x + 3) - 5
f(x) = -4(x² + 6x + 9) - 5
f(x) = -4x² - 24x - 36 - 5
f(x) = -4x² - 24x - 41
Dy/dx = -8x - 24
At minimum Dy/dx = 0
-8x - 24 = 0
-8x = 24
x = 24/-8
x = -3
At minimum
y = -4x² - 24x - 41
y = -4(-3)² - 24(-3) - 41
y = -4(9) + 72 - 41
y = -36 + 72 - 41
y = 36 - 41
y = -5
So he has road 5.75 miles and 1/8=0.125 so i am going to estimate but 4.12 miles left to cover
