Answer:
Step-by-step explanation:
Using the growth formula
H = H₀ ( 1 + r) ^n
where H is the present height, H₀ is the initial height at which the plant was grown, r is the rate and n is the number of days
H = H₀ ( 1+0.07)^2.79
15.7 = H₀ (1.07)^2.79
15.7 / (1.07)^2.79 = H₀
H₀ = 13 inches
Height after one day = 13 ( 1.07)¹ = 13.91 and the growth factor is 1.07
On day 0 the sunflower measured 13 inches, while on day 1 it measured 13.91 inches.
Since a sunflower is planted in a garden and the height of the sunflower increases by 7% per day. 2.79 days after being planted the sunflower is 15.7 inches tall, to determine what is the 1-day growth factor for the height of the sunflower the following calculation must be performed:
- X x (1 + 0.07) ^ 2.79 = 15.7
- X x 1.07 ^ 2.79 = 15.7
- 1.2077X = 15.7
- X = 15.7 / 1.2077
- X = 13
- 13 x 1.07 = 13.91
Therefore, on day 0 the sunflower measured 13 inches, while on day 1 it measured 13.91 inches.
