Answer:
603
Step-by-step explanation:
The rate of change is found by
rate of change = f(b) -f(a)
------------
b-a
We need to find the rate of change for the interval 7,9 and 4,6
We know b= 9 and a = 7
f(9) -f(7)

Answer:
B. 18
Step-by-step explanation:
Base: 3-(-6)=9
Height: 6-2=4
Area =1/2bh = 1/2(9)(4)= 18 square units

Answer:
Steve should use:
- 8.53 Inch of Wire to make the circle
- 43.47 Inches of Wire to make the Square.
Step-by-step explanation:
Let Steve cut the wire so that the first piece has length x.
Therefore, the second piece will have a length of (52 - x).
The wire of length x is used to make a circle
Circumference of a Circle,


The wire of length (52-x) is used to make a square.


Total Area = Area of Circle + Area of Square

Let us simplify the expression

This is the function of a parabola which opens up.
To find where A is minimum, find the axis of symmetry.


Steve should cut the wire so that the length of wire used to make a circle is 8.53 Inches.
Length of wire used to make the square =52-8.53=43.47 Inches
