Answer:
4
Step-by-step explanation:
360 deg = 20
1 deg = 20/360
72 deg = 20/360 * 72 = 4
Answer:
19 is the area for the problem
Answer:
Step-by-step explanation:
11. Write in point slope form first;
y+4 = (x+1)^2; Convert to standard form;
y=x^2+2x+1-4
y = x^2+2x-3; Final standard form
12. Convert the original point-slope form with the vertex given;
y-3 = a(x-4)^2; plug in the point (1,12) to solve for a;
12 -3 = a(1-4)^2
9 = 9a
a = 1
y-3 = (x-4)^2
y=(x-4)^2+3: Final vertex from
13. The vertex is at (-1,-4)
y +4= (x+1)^2; Factored form can mean many things;
this is the equation of the function; factor it how your teacher taught you.
