Answer:
A
Step-by-step explanation:
the maximum turning point is on the top and minimum on the bottom in this case maximum Is above the X-axis
C=2πr
r=C/(2π), now the surface area is:
A=4πr^2, using r found above we have:
A=4πC^2/(4π^2)
A=C^2/π, we are given that C=28 so:
A=28^2/π in^2
A=784/π in^2
A≈250 in^2 (to nearest square inch)
Let y = (b)ˣ
1) if b> 0, then growth, whatever the value of x>0
2) if b< 0, then decay, whatever the value of x >0
3) if b<0, then decay, whatever the value of x >0
4) if b<0, then growth, whatever the value of x <0
The answe is 1.7x10 exponent 5
