Answer:
Step-by-step explanation:
y^2-22y+c
complete the square ax^2+bx+c is our old formula quadratic equation
we know that to find c we will divide b/2 and square it
22/2=11
c^2=121
we have y^2-22y+121

Answer:
161.8cm²
Step-by-step explanation:
solve for height which is the opposite
opp=x
sin(theata)= opp./hyp.
sin23=x/30
x=30×sin23
x=11.72cm
height=opposite
height=11.72cm
base=adjacent
base=27.6cm
½of 27.6cm=13.8
13.8cm×11.72cm=161.74 (2d.p)
161.74 rounded to the nearest tenths= 161.7
I'm not sure if it's the answer but it's the closest thing to the options
Answer:
domain: 0 - 10 range: 0 - 32
Step-by-step explanation:
Take the lowest x and the highest x and put them in set values to get domain.
lowest x = 0 and highest x = 10.
Take the lowest y and the highest y and put them in set values to get range.
lowest y = 0 and highest y = 32
Ok
So when you multiply by a fraction just multiply top by top and bottom by bottom
So top by top is 2 by 4 so 8
And bottom by bottom is 3 by 5 which is 15
So answer is 8/15
