The answer to this is B. 8/5 pounds.
8 pounds divided into 5 piles=1.6 or 8/5
Answer:
A) car one is linear because it decreases the same amount every year.
car two decreases by the same ratio so it's exponential.
B) for car one y = -6,000x + 38,000 (y is the value after x years, -6,000 is what it changes by every year, and 38,000 is the amount of year 0)
for car two y = (44,000) (17/20)x-1 (y is the value after x years, 44,000 is the amount on year 0, and 17/20 is the ratio)
C) after 5 years car one will be 8,000
after 5 years car two will be about 16,860
It will take 5.83 hours for the bacteria to reach 1119.
<h3>What is exponential Growth ?</h3>
Exponential growth is when the quantity increases according to the function
It is given in the question that
Initial number of Bacteria is 50
After 3 hours the bacteria has increased to 80
The bacterial growth is an exponential growth
Applying log on both sides
1.6 = 3*k
k = 1.6/3
k = 0.533
if this rate of growth continues, how much more time will it take for the number of bacteria to reach 1119
Therefore it will take 5.83 hours for the bacteria to reach 1119.

Well I think that for this problem we should multiply 3x1/3 which is 1 whole. Sorry if I'm incorrect.
Answer:
f(x) = 8x² + 2x - 5
Step-by-step explanation:
I think you meant to put an 8 instead of *.
Anyways, f(x) = 8x² + 2x - 5 is a quadratic function because there is 8x² in the function.
