Answer:
The growth factor is approximately 0.11 or 11%.
Step-by-step explanation:
We have been given that a 8-inch tall sunflower is planted in a garden and the height of the sunflower increases exponentially. 5 days after being planted the sunflower is 13.4805 inches tall.
We will use exponential growth formula to solve our given problem.
, where,
y = Final value,
a = Initial value,
r = Growth rate in decimal form,
x = Time.
Upon substituting initial value
,
and
, we will get:




Now, we will take 5th root of both sides of equation as:
![\sqrt[5]{(1+r)^5} =\sqrt[5]{\frac{13.4805}{8}}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B%281%2Br%29%5E5%7D%20%3D%5Csqrt%5B5%5D%7B%5Cfrac%7B13.4805%7D%7B8%7D%7D)
![1+r =\sqrt[5]{1.6850625}](https://tex.z-dn.net/?f=1%2Br%20%3D%5Csqrt%5B5%5D%7B1.6850625%7D)




Therefore, the growth factor is approximately 0.11 or 11%.
Answer:
A then B
Step-by-step explanation:
1440≈1,000, and 1,000=10^3
1000000/1440≈700, and 700≈1,000. 1,000=10^3
Expand the equation.
Multiply (distribute) the first numbers of each set, outer numbers of each set, inner numbers of each set, and the last numbers of each set.
Combine like terms.
Solve the equation and simplify, if needed.
Answer:
39 miles/1 hr
Step-by-step explanation:
13m=20min
20x3=60min
60min=1hour
13x3=39
39m=1hour
unit rate:
39 miles/ 1 hr
