f(x)=x2+14x+40 => <span>f(x)=x^2+14x+40
Next, complete the square:
</span>f(x)=x^2+14x+ 49 - 49 +40 = (x+7)^2 - 9
Write this in the form y = (x+7)^2 - 9 or y + 9 = (x+7)^2
Comparing this result to y = a(x-h)^2 + k, we see that h = -7 and k=-9
In vertex form, the equation is y + 9 = (x+7)^2 and the vertex is at (-7, -9).
Answer:
3
Step-by-step explanation:
Answer:
Radius = 9
Step-by-step explanation:
Circumference = 2πr
2πr = 18 ×3.14
2πr = 56.5
6.28r = 56.5
r = 56.5/6.28
r = 9.04 round off , 9
? is equal to 4 because you can cancel out the 2 and the 5 from both sides and you are left with 4.
