Answer:


Step-by-step explanation:
Given


Represent the combination of f(n) and g(n) with A(n)
So, we have:

This gives:

To calculate the 11th term, we make use of n = 11


This gives:



Approximate to 2 dp

Answer:
1,059.75
Step-by-step explanation:
well the silver car is less then a green car right but just add them up
A. -1
(1,2) and (2,1)
slope = 2 -1 / 1 -2
slope = 1 / -1
slope = -1
Answer:

∠
°
Step-by-step explanation:



- The cosine of an angle is equal to the side adjacent to the angle over the hypotenuse, the longest side.

- We need to find the hypotenuse of this triangle. This is relativly easy to do with a right triangle; we can just use the Pythagorean Theorem.
- Pythagorean Theorem:
where
,
, and
are the 3 different sides of a right triangle.

- Our hypotenuse is
. Now we can finish solving for ∠
.
