Answer:
Negative: (-∞,-3] and [1/2,-∞)
Positive: [-3,1/2]
Step-by-step explanation:
The derivative is the instantaneous rate of change at any given point for a function. Given this we know that anywhere the function is in the positive or negative direction, the derivative will also be in the positive or negative direction. We also know that wherever there is a peak or a trough, there will be no slope and it signifies a change in direction. For this function, this means the direction changes at -3 and 1/2.
The volume of a rectangular prism is always LWH=V, the cube is a special prism in that L=W=H are all equal so:
V=s^3 where s is the length of all sides...
s^3=1728
s=1728^(1/3)
s=12 units
Answer:
m^2+m+1
Step-by-step explanation:
- m^3 - 1= (m-1)(m^2+m+1)
- m^4 + m^2 + 1= m^4+2m^2+1 - m^2= (m^2+1)^2 -m^2= (m^2+m+1)(m^2-m+1)
- m^2+ m + 1
HCF= m^2+m+1 which is the factor of all three polynomials
Answer:
length × width × height.
Step-by-step explanation:
we have
Separate the equation above in two equations
equation 
equation 
we know that
In a system of equations the roots of the equation must satisfy equation and the roots of the equation must satisfy equation
therefore
the answer is
The system of equations is
