Answer:
around 5.5 inches
Step-by-step explanation:
34.48 = 2rπ
34.48/π = 2r = around 11
r = 11/2
Y = x² + 4x + 4.. Since the coefficient of x² =1, is positive, then this parabola opens upward & has a minimum.
Its axis of symmetry is = -b/a = -4/1 = 4 (so x=4)
1) When x=4, y= 4²+4(4)+4 => y=36 so the VERTEX has a minimum is at (4,36)
2)FOCUS.: To be able to calculate the focus, rewrite the equation in a standard form: y-k =a(x-h)² & y = x² + 4x + 4 could be written y=(x+2)², this means that k=0 & h=-2.
Now p being the distance between the VERTEX & the FOCUS, we apply the formula (x-2)² = 4P (y-k) , but k=0 & h=2 then (x-2)² = 4P(y-0) then P =1/4
3) DRECTRICE : y=k-P = 0-1/4 ==> y=-1/4 is the directrix
Answer:
-4
Step-by-step explanation:
Answer:
So, The answer would be 1=k
Step-by-step explanation:
My step is to make a T-chart, as u make it put X on one side and Y on the other
So what i did was i put 0 for both of them because it had start at 0
then i followed the line to the dot as i did that It has 6,6 so then i figured out what multiply all those number and the answer was 1=k
And another way you could do it was to make 6,6 and fraction like 6/6 then divde them both and get 1=k
So you would put the answer as 1
thats it Answer-1
