Answer:
PR = 3.2
Step-by-step explanation:
We can use proportions to solve this problem. Put the first triangle side over the second triangle side.
BC AC
-------- = ----------
QR PR
Substituting in values
10 8
4 PR
Using cross products
10 PR = 8*4
10 PR = 32
Divide by 10
10 PR/10 = 32/10
(-2,-12), (-1,-6), (0,-3) and (1,-3/2)
g(x) = -3(1/2)^x
Putting values of x
x g(x)
-2 -3(1/2)^-2 = -12
-1 -3(1/2)^-1 = -6
0 -3(1/2)^0 = -3
1 -3(1/2)^1 = -3/2
Now, making the graph we will plot
The graph is shown in figure below.
