I just answered this xD
1-3 is given as an example.
4. True
5. False. It is the same thing twice
6. True
If the function 1 in graph is a horizontal line y=3 then it has zero rate of change because y is same along the x axis.
Function 2 has rate of change of 2.
Y=mx+c m represents rate of change
You are given
the surface area of the cube which is 96cm2. You are asked to find the length
of one side and its volume. Note that the surface area of the cube is equal to
6 times the square root of s (the side of the cube) and the volume is the cube
root of s. So,
SA = 6*s^2
96cm2 = 6*s^2
s^2 = 16cm
<u>s = 4cm,
this is the length of one side.</u>
V = s^3
V = (4)^3
<u>V = 64cm3,
this is the volume of the cube.</u>
Y=4
3y/4=12/3
y=4 3/3=1
12/3=4 so y=4
