Exponential function is characterized by an exponential increase or decrease of the value from one data point to the next by some constant. When you graph an exponential function, it would start by having a very steep slope. As time goes on, the slope decreases until it levels off. The general from of this equation is: y = A×b^x, where A is the initial data point at the start of an event, like an experiment. The term 'b' is the constant of exponential change. This is raised to the power of x, which represents the independent variable, usually time.
So, the hint for you to find is the term 500 right before the term with an exponent. For example, the function would be: y = 500(1.8)^x.
Answer:
C, 4.123
Step-by-step explanation:
√(17) which equals 4.12
Answer:
The correct answer is NO. The best price to be charged is $3.75
Step-by-step explanation:
Demand equation is given by Q = 30 - 4P, where Q is the quantity of necklaces demanded and P is the price of the necklace.
⇒ 4P = 30 - Q
⇒ P = 
The current price of the necklace $10.
Revenue function is given by R = P × Q = 
× ( 30Q - 
)
To maximize the revenue function we differentiate the function with respect to Q and equate it to zero.
= × ( 30 - 2Q) = 0
⇒ Q = 15.
The second order derivative is negative showing that the value of Q is maximum.
Therefore P at Q = 15 is $3.75.
Thus to maximize revenue the price should be $3.75.
To make a fraction to its simplest form, you have to divide the numerator and the denominator by the same number. For this question, divide 140 and 216 by 4. You will get 35/54. Since you can't divide this further, the simplest form of 140/216 is 35/54.
