I think as in whole numbers in numerator it should be in improper fraction since 4.5= 4wholes and 5/10 it's 9/2?
and 2.5 in mixed fraction is 2 wholes 5/10 in improper is 5/2
unless you say mixed fraction is okay to leave if for the answer than it's respectively 4wholes 1/2 and 2wholes 1/2?
I'm not sure but I learnt this in my school and it goes like this

Step-by-step explanation:
Tricky. Very neat.
You are missing the minor arcAC and you need it, but don't fret. It can be found.
The formula for this is x = 1/2(Major Arc(235) - Minor Arc(see below) )
The minor arc is the supplement of x.
The minor arc is also equal to the the central angle
So the minor arc is 180 - x
x = 1/2 (235 - (180 - x) ) Remove the inside brackets
x = 1/2 (55 + x ) Remove the remaining brackets
x = 1/2 *55 + 1/2x Subtract 1/2x from both sides
1/2 x = 27.5 Multiply both sides by 2
x = 55
Answer:
steps below
Step-by-step explanation:
a) f(x) = (x+2)² - 9
b) y = (x-h)² + k , (h,k) is vertex vertex (-2 , -9)
x intercept: (x+2)² - 9 = 0
x+2 = ± 3
<u>x = 1 or x = -5</u>
y intercept: <u>y = -5</u>
c) attached
d) y ≥ -9 [-9,∞)
