Answer:
25.63694268 = r
Step-by-step explanation:
The circumference is
C = 2*pi*r
161 = 2*(3.14) *r
161 = 6.28 r
Divide each side by 6.28
161/6.28 = r
25.63694268 = r
Start with y = x2
Shift 2 units left to get y = (x+2)2
Vertically stretch to get y = 6(x+2)2
Reflect across x-axis to get y = -6(x+2)2
Shift 7 units down to get y = -6(x+2)2 - 7
hope this helps!
Caroline and Ron have 11 fish in total.
Let C be Caroline and R for Ron.
C+R =11
Ron has 3 less so, C has 7 and R has 4
