Since south and west are at 90 degree angle that means we can use pythagorean theorem to find the distance.
It goes like this:
c^2 = a^2 + b^2
a = 3
b = 4
implementing this in pythagoras formula we get that c = 5
answer is 5 miles southwest
Answer:
2
Step-by-step explanation:
Use slope formula: (y2-y1)/(x2-x1)
(14-6)/(8-4) = 8/4 = 2
The gradient is 2
Answer:
The 3rd option, so C
Step-by-step explanation:
Answer:
The cost in 2015 will be $283.45.
What is the reference point (t=0)?
d. The year 2005.
Step-by-step explanation:
The exponential growth model for the cost is the following:

In which C(t) is the cost after t years,
is the initial cost and r is the decimal inflation rate
In this problem, we have that:

What will it cost in 2015 assuming the rate of inflation remains constant?
2015 is 10 years after 2005, so this is C(10).


The cost in 2015 will be $283.45.
The reference point is the year in which t = 0, so the year 2005.
A function in math is a relationship or expression involving one or more variables.
