slope is 2 and y-intercept is (0, 4)
Step-by-step explanation:
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

Circumference = πD
π*49 = 153.94 (We can leave it as it is because there are two halves to the circle on either side of the training track)
81*2 = 162 (There are two 81 meter lines)
153.94+162 = 315.94m
The length of the training track is 315.94m
Hope this helps! :)
Answer:
x = 6, y = -8
Step-by-step explanation:
First we take the equations side by side and put them like this:
6x + 2y = 16
+ 2x - 2y = 32
8x = 48
Then solve for x.
x = 6
Then insert x back into either equation
2(5) - 2y = 32
10 - 2y = 32
solve for y,
y = -10
