-w/4=5

5*4=20

-w=20

-1/20=-20

w=-20

Solve for w by simplifying both sides of the equation, then isolating the variable.

w = -20

Hope this helped!!

The roots of Billy's plant grew to 3 inches beneath the Earth’s surface. Graph all the possible depths the roots can continue to
vaieri [72.5K]
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.

Radium-228 has a half-life of 5.75 years. What is the decay rate for radium-228?
artcher [175]

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:

ln\frac{N_o}{N_t}=-\lambda t

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, \frac{N_o}{N_t}=0.5

t= 5.75 years

We need to find λ

Putting values in formula and solving:

ln\frac{N_o}{N_t}=-\lambda t

ln(0.5)=-\lambda *5.75\\-\lambda=\frac{ln(0.5)}{5.75}\\-\lambda=\frac{-0.69}{5.75}\\-\lambda=-0.1205\\\lambda=0.1205

So, Decay rate for Radium-228 is 0.01205.

Solve for m when: 3-2m=-1​
kati45 [8]
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
