The height of a plant over time is shown in the table below. Using a logarithmic model, what is the best estimate for the age of the plant when it is 19 inches tall? plant height t, time in months h, height in inches 1 18 2 18. 21 3 18. 33 4 18. 42 5 18. 48 6 18. 54 10 months 14 months 16 months 28 months
The best estimate for the age of the plant at 19 inches tall height is; 28 months
How to use a logarithmic Model?We are given the time in months as;
1, 2, 3, 4, 5, 6 months.
We are also given the corresponding heights for those months respectively as; 18.2, 18.21, 18.33, 18.42, 18.46, 18.54
Now, when we punch those values into an online regression calculator, we arrive at the regression equation as;
y = 18.001 + 0.3ln(x)
We want to find the best estimate for the age of the plant at 19 inches tall height. Plugging in 19 for x in the regression equation gives;
y = 18.001 + 0.3ln(19)
Solving theis gives; y = 28 months

A wheel is turning about an axis through its center with constant angular acceleration. Starting from rest, at t = 0, the wheel turns through 8. 20 revolutions in 12. 0 s. At t = 12. 0 s the kinetic energy of the wheel is 36. 0 j. For an axis through its center, what is the moment of inertia of the wheel?
Answer: 0.975 m^2
Explanation:
θ = 0.5αt^2
8.20 revolutions = 8.20 x 2π = 51.52 rad
51.52 = 0.5α(12)^2
α = 0.716 rad/s^2
ω = αt = 0.716(12) = 8.592 rad/s
KE = 1/2Iω^2
36 = 0.5I(8.592)^2
I = 0.975 m^2
Therefore, the moment of inertia of the wheel is approximately 0.975m^2

What is the oxidation number for bromine in the molecule h2br2o6
Taking into account the definition of oxidation number, the oxidation numbers for bromine in the molecule H₂Br₂O₆ is +5.
Definition of oxidation numberThe oxidation number is the charge that an atom has; is an integer that represents the number of electrons an atom puts into play when it forms a given compound.
In other words, the oxidation number of an element is a value that indicates the number of electrons that element gains or loses when it combines with another.
Oxidation number determinationTo determine the oxidation state of different elements it is necessary to know that:
The oxidation number of hydrogen in a compound is +1, except in metal hydrides, where is –1.The oxidation number of oxygen in a compound is –2, except in peroxides, where it is –1.On the other side, the sum of the oxidation numbers of the existing elements in a chemical formula must add up to zero.
Then, considering the oxidation numbers of each element, multiplying it by the number of existing elements in the chemical formula and adding it and equaling it to zero, the value of the missing oxidation number can be obtained.
Oxidation number for bromineIn this case, the oxidation numbers of bromine is calculated as:
H₂Br₂O₆: 2× (+1) + 2× (oxidation numbers of nitrogen) + 6×(-2)= 0
2 + 2× (oxidation numbers of nitrogen) - 12= 0
2× (oxidation numbers of nitrogen) - 10= 0
2× (oxidation numbers of nitrogen) =10
oxidation numbers of nitrogen= 10÷2
oxidation numbers of nitrogen= +5
Finally, the oxidation numbers for bromine in the molecule H₂Br₂O₆ is +5.

How far below the bridge will kate eventually be hanging, once she stops oscillating and comes finally to rest? assume that she doesn't touch the water
The distance below the bridge that kate will eventually be hanging, once she stops oscillating and comes finally to rest is: d = mg/k + L.
DistanceLetForce exerted by a spring=F=kx
Let x = (d – L)
Let d= Total length of the bungee cord
Let set this equal to the gravitational force
F(spring) = k(d – L)
F(gravity) = mg
Hence:
k(d – L) = mg

A retail outlet is being designed in a strip mall in nebraska. For this outlet, the installed fiberglass insulation to protect against heat loss in the winter and heat gain in the summer will cost an estimated $100,000. The annual savings in energy due to the insulation will be $18,000 at eoy one in the 10-year life of the outlet, and these savings will increase by 12% each year thereafter. If the annual interest rate is 15%, is the cost of the proposed amount of insulation justified?
The cost of insulation is not justified because the current equivalent energy savings is $88,000, which is less than the price of insulation. Installation will set you back $90,000.
What is insulation?Insulation is defined as a material created to stop heat or sound from spreading from one place to another. Additionally helpful in lowering noise pollution is insulation. An energy-efficient home will use very little extra energy for heating and cooling.
Current equivalent energy is defined as the energy that an electron gains when its electrical potential rises by one volt. There are numerous ways that this action can occur, including thermal, electromagnetic, mechanical, and electrical. The principle of mass energy equivalence states that energy and mass have equivalent amounts.
