Complete Question:
Suppose a local vendor charges $2 per hot dog and that the number of hot dogs sold per hour is given by 
, where is the number of hours since 10 AM:
a) Find an expression for the revenue per hour as a function of x, R(x)
b) Find and simplify, R(x(t))
Answer:
a) R(x) = 2x
b) 
Step-by-step explanation:
a) This is a very trivial exercise.
The number of hot dogs sold per hour is given by x
Charge per hot dog = $2
An expression of revenue per hour,R, as a function of the number of hot dogs sold per hour, x, is therefore: R(x) = 2x
b)
R(x(t)) = 2(x(t))
Answer:
76.
Step-by-step explanation:
Here, a=3, b=-10 and c=2. Substitute the values, Therefore, the discriminant of is 76.
Answer: x2+3x+4+18/x-3
Step-by-step explanation:
The mathematical property demonstrated by 7+9+3=7+3+9 would be the commutative property. This property states that in operations such as addition and multiplication, when you switch the order of the numbers around, the result will always be the same. In 7+9+3=7+3+9, no matter what order you put the numbers in, the answer will always be 19.
