The function f(x) = (6/120) x + 40
= 0.05x + 40 where x is the excess mileage over 100
If we drive it for 300 miles x will be 300-100 = 200
so cost will be 0.05*200 + 40
= 10+40 = $50 answer
Answer:
Part 1)
Part 2) The height of the pole is
Step-by-step explanation:
Let
x------> the length of the pole
y------> the length of the shadow
we know that
-----> equation A
Applying the Pythagoras Theorem to find the distance (hypotenuse in a right triangle)
-----> equation B
substitute equation A in equation B and solve for x
squared both sides
-----> equation that represent the situation
solve for x
