Answer:
17.5 hours
Step-by-step explanation:
107 = 60(2^n)
n(lg2) = lg(107/60)
n = 0.8345763908 × 21
n = 17.52610421 hours
Answer:
<h2>f(2) = - 12</h2>
Step-by-step explanation:
f(x) = x - 14
To find f(2) substitute the value of x that's 2 into f(x). That is for every x in f(x) replace it with 2
We have
f(2) = 2 - 14
We have the final answer as
<h3>f(2) = - 12</h3>

Answer:
Step-by-step explanation:
The better buy is the one where you get more area of pizza per dollar (area/price).
Since the problem gives diameter, we assume the pizzas are circle-shaped.
Circle Area = pi x (radius)², and radius r = 1/2 of diameter d.
*************************************************************************************
Pizza 1: d = 8 and price is $10
r = 1/2 x d = 4
Area of Pizza 1 = πr² = π(4)² = 16π
*** area/price for Pizza 1 = 16π/$10 = 1.6π area per dollar
**********************************************************************************
Pizza 2: d = 14 and price is $16
r = 1/2 x d = 7
Area of Pizza 2 = πr² = π(7)² = 49π
*** area/price for Pizza 2 = 49π/16 = 3.0625π area per dollar
***********************************************************************************
Pizza 2 is the better buy, with more pizza per dollar.
