Answer:
30.3 cm
Step-by-step explanation:
Suppose the height is h after the sphere is full submerged.
4/3R³ =
r²(h-30) The volume of the sphere is equal to the volume
4/3(10/2)³=
× (14/2)²(h-30) of the water surface rising
4/3 × 125 = 49 × (h-30)
h - 30 = 49 × 3/4 × 125
h - 30 = 0.3
h = 30 + 0.3
h = 30.3 cm
Answer:
20
85%
Step-by-step explanation:
You are given the function
If n is the number of hours, then initially n=0 and
If S(n) is the function of exponential growth, then it can be represented as
where I is the initial amount, r -is the percent growth rate and n is the number of hours.
If b = 1.85, we can represent it as b = 1 + 0.85. Thus, the hourly percent growth rate of the bacteria would be 0.85=85%.
