Answer: 0.8(.50)^t/5
Step-by-step explanation:
P(t)= p^0(1+-r)^t
0.8= initial mass
.50= 100/2-> halving
t/5= how many times for every 5 days
Move the negative sign to the left
-x/5 = -20
Multiply both sides by 5
-x = -20 × 5
Simplify 20 × 5 to 100
-x = -100
Multiply both sides by -1
<em>x = 100</em>
<u>C. 100</u>
f(x) = 3/(x + 2) - √x - 3
f(7) = 3/(7 + 2) - √7 - 3
f(7) = 3/9 - √4
f(7) = 0.333 - 2
f(7) = -1.67
