Step-by-step explanation:
1.
and
then by segment addition postulate

2. Consider triangles PQU and TSU. These triangles are similar by AA similarity theorem (triangles have congruent vertical angles PUQ and TUS and congruent alternate interior angles PQU and TSU). Similar triangles have proportional corresponding sides, so


3. Consider triangles QUV and QSR. These triangles are similar by AA similarity theorem. Similar triangles have proportional corresponding sides, so

so

Answer:
f(x) = 9x^2-36x+37
Step-by-step explanation:
3(x-2)^2+1
(3x-6)^2+1
9x^2-36x+36+1
9x^2-36x+37
Answer: $1114.91
Step-by-step explanation:
The formula for compound interest is

Where
A = final amount
P = initial principal balance (1030 for this)
r = interest rate (0.04 for this)
n = number of times interest applied per time period (2 for this)
t = number of time periods elapsed (2 for this)

This rounds up to $1114.91
