No its not polygons dont cross lines
For to be conservative, we need to have
Integrate the first PDE with respect to :
Differentiate with respect to :
Now differentiate with respect to :
So we have
so is indeed conservative.
Answer: 18x^4 - 5x^3 + x^2 - 4
Step-by-step explanation:
We need to add like terms.
-10 and 6 are like terms
-10 + 6 = - 4
-3x^3 and -2^3 are like terms
-3x^3 + -2^3 = -5x^3
There are no other like terms.
18x^4 - 5x^3 + x^2 - 4
Answer: 4 seconds
Step-by-step explanation:
Given: The function can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.
Differentiate the given function with respect to t , we get
Put h'(t)=0
Also,
By second derivative test, h(t) is maximum at t=4.
Hence, the time in Devon which the ball reaches it maximum height = 4 seconds
Answer:
PA = 8
Step-by-step explanation:
formula is C^2 = E * (A + E)
C^2 = 4 * (12 + 4)
C^2 = 64
c = 8
C = PA = 8
