Answer:
The room is square. This is because it says "diagonal of the floor..." Which means it is from one corner of the room to the opposite end.
Step-by-step explanation:
It says "four wall room" which means it is a square. It also states that each wall meet at a right angle. To through you off this question stated the word 'diagonal' to mess with you when reading this question quickly. If you look more detailed and I like to re-read sentences in order to recognize all the information given. So the Room IS a Square.
Convert to vertex form:-
y = 5(x^2 - 2x) + 1
y = 5[(x - 1)^2 - 1] + 1
y = 5(x - 1)^2 - 4
vertex is (1, -4)

Answer:
$1876.31
Step-by-step explanation:
The present value can be found using the compound interest formula.
<h3>Present value</h3>
The formula for the future value of an investment of P earning annual interest rate r compounded n times per year for t years is ...
FV = P(1 +r/n)^(nt)
Filling in the known values gives ...
4000 = P(1 +0.085/4)^(4·9) = P(1.02125^36)
Then the amount to be invested is ...
P = 4000/1.02125^36 ≈ 1876.31
The present value is $1876.31.
