The plants are starting at -3, I would say that the plants can grow further down past negative three.
I would draw an open circle at -3, then have the arrow pointing to the left. This shows that the roots can grow lower than -3.
Answer:
c) 11
Step-by-step explanation:
g(x)= x² + 2
x = 3
substitute x for 3
g(3) = (3)² + 2
g(3) = 9 + 2
g(3) = 11
Decay rate for Radium-228 is 0.01205
Step-by-step explanation:
The half life of radium-228 is 5.75 years. We need to find the decay rate for radium.
The formula used is:

Where N₀ = amount of radioactive particles at time = 0
N_t = amount of radioactive particles are time (t)
λ = rate of decay constant
t = time
We are given half life so,
=0.5
t= 5.75 years
We need to find λ
Putting values in formula and solving:


So, Decay rate for Radium-228 is 0.01205.

Answer:
4
Step-by-step explanation:
because 2+2+2+2=8 pretty self explanatory
M = 2
3 - 2m = -1
subtract 3 from both sides
-2m = -4
divide by -2 on both sides
m = 2
the answer is positive since a negative divided by a negative is positive
