Answer:
Step-by-step explanation:
a) The cost of a product is given as:
Cost = a + bx
Where a is the fixed cost, b is the variable cost, x is the independent variable.
In this case, the independent variable is the distance(d), therefore:
Cost (C) = a + bd
C = a + bd
But the variable cost is $10/km, therefore:
C = a + 10d
A 2.5 km trip cost $40, therefore:
40 = a + 10(2.5)
40 = a + 25
a = 40 - 25 = 15
The fixed cost is $15. Therefore the equation for cost is:
C = 15 + 10d
b) C = 15 + 10d
For 6.5 km ride:
C = 15 + 10(6.5) = 15 + 65 = 80
It would cost $80 for a 6.5 km drive.
Answer:
0 hot items and 11 cold Items
Step-by-step explanation:
The other combinations will be more than $25 but
11(3)=22 which is even lower than $25
Answer:
I don't see any expressions shown below.
Step-by-step explanation:
The vertical asymptote of the function f(x) = 3 log(x + 3) is x = -3
Step-by-step explanation:
A symptote is a line that a curve approaches but never touches
- The vertical asymptote of a logarithmic function is at the zero of the argument
- f(x) = log(argument) has vertical aymptotes at argument = 0
∵ f(x) = 3 ㏒(x + 3)
∵ The argument is (x + 3)
- Equate the argument by zero
∵ x + 3 = 0
- Subtract 3 from both sides
∴ x = -3
- The vertical asymptote of a logarithmic function is at the zero
of the argument
∴ The vertical asympotote of f(x) is x = -3
The vertical asymptote of the function f(x) = 3 log(x + 3) is x = -3
