Answer:Ok, we have:
d(t) = 3*t^2 + 5*t - 2.
The first interval is:
(2, 3)
and remember that, for an interval (a,b), the difference quotient is:
D = (f(b) - f(a))/(b -a)
Then in this first interval we have:
So the average rate of change in (2,3) is 20.
now, in (2, 2.5) we have:
So here the rate of change is 9.25
And in the interval (2, 2.1) we have:
So in this interval the rate of change is 1.73

Answer: Sorry I am not sure about it
I do know how to dxo this but this one is hard for me sorry 56456
Step-by-step explanation:
Set up an equation.
width = x
length = 56 - 2x
Multiplying length * width makes area. 56x - 2x^2 = Area.
y = -2x^2 + 56x
Ax^2 + Bx = C
Solve for the vertex: x = -(b/2a)
-(56/-4) = 14
width = 14 ft.
length = 56 - 2(14) = 28ft.
14*28 = 392 sq. ft.
R = 7
Solving for the circumference first,
C = 2(π)(r)
C = 2(π)(7)
C = 14(π)
C = 43.96
You would need to round up to 44 then.
The area of a circle is
A = π(r²)
A = π(7²)
A = π(49)
A = 153.86
You would round up to 154.
Circumference = 44
Area = 154
