An exponential growth function describes an amount that decreases exponentially over time?
an exponential growth function describes an amount that increases exponentially over time.
What is Einstein's photoelectric equation?
E(photon energy)=K.E+Work Function
The half-life of a certain radioactive material is 75 days An initial amount of the material has a mass of 381 kg Write an exponential function that models the decay of this material Find how much?
The generalized exponential half-life equation is ... AT = A0 2(-T/H) ... where A0 is the initial activity, AT is the final activity at time T, and H is the half-life in units of time T. Example using the specific question, for an elapsed time of 50 days, is ... A50 = (381) 2(-50/75) = 240
How do you show that a wave function is a solution to the time- independent Schrodinger equation for a simple harmonic oscillator?
You should substitute your solution in the equation. If the solution is correct you will receive equality. Otherwise your solution is wrong.
What eventually happens to a population experiencing exponential growth?
A form of population growth in which the rate of growth is related to the number of individuals present. Increase is slow when numbers are low but rises sharply as numbers increase. If population number is plotted against time on a graph a characteristic J-shaped curve results (see graph). In animal and plant populations, such factors as overcrowding, lack of nutrients, and disease limit population increase beyond a certain point and the J-shaped exponential curve tails off giving an S-shaped (sigmoid) curve. occurs when the growth rate of a mathematical function is proportional to the function's current value.
What is the difference between power functions and exponential functions?
A power function has the equation f(x)=x^a while an exponential function has the equation f(x)=a^x. In a power function, x is brought to the power of the variable. In an exponential function, the variable is brought to the power x.
What the difference between an exponential equation and a power equation?
y = ax, where a is some constant, is an exponential function in x y = xa, where a is some constant, is a power function in x If a > 1 then the exponential will be greater than the power for x > a
How do we differentiate between a quadratic equation and an exponential equation?
a quadratic equation must be in this form ax^2+bx+c=0 (can either be + or -) an exponential just means that the function grows at an exponential rate f(x)=x^2 or x^3
How do you know if an equation is exponential?
Basically, in an exponential expression (or equation) you have the independent variable in the exponent. For example: 5 times 10x The general form of an exponential function can be written as: abx or: aekx where a, b, and k are constants, and e is approximately 2.718. Note that just having a power doesn't mean you have an exponential equation. For example, in x3 the variable does NOT appear in the exponent, so it is not an exponential expression.
A function takes the exponential function's output and returns the exponential function's input?
A __________ function takes the exponential function's output and returns the exponential function's input.
What is the purpose of semi logarithm?
The y-axis on a semi logarithmic chart is exponential. This way, when an exponential function is depicted in the chart, it will evolve as a linear function. You often do this to proove that the function is exponential and/or as a tool to help you find the equation for the function. For more see: http://www.answers.com/topic/semi-logarithmic-plot
If you horizontally compress the exponential function f(x) 2x by a factor of 4 which of these is the equation of the new function?
It is f(x) = 8x.
What is the parent function for the exponential function?
The parent function of the exponential function is ax
Is the inverse of an exponential function the quadratic function?
No. The inverse of an exponential function is a logarithmic function.
