Answer:
a is an even number and b is an odd number
Step-by-step explanation:
if a is even and b is even then the sum would be even ex.10+6=16. I'd a and b are both odd the sum would be even ex. 13+9=22. one has to be odd and one has to be even for the sum to be odd ex. 5+4=9
Answer:
51.9

Answer:
88.5
Step-by-step explanation:
(90+82+81+2x)/5=86
90+82+81+2x=430
2x=177
x=88.5
Answer:
h(t) = 1.5t²/2 + 4t +12
Step-by-step explanation:
The growth rate is given by
dh/dt = 1.5t + 4
To determine the height of the seedlings we integrate the rate with respect to t.
The integral of dh/dt = integral of 1.5t + integral of 4
The integral of dh/dt = h
The integral of dh/dt = 1.5t²/2 + 4t
So at t = 0
h = 12
That makes the equation
h = 1.5t²/2 + 4t +12
Where 12 is the constant
So h(t) = 1.5t²/2 + 4t +12
Will give us the height after t years
