A hospital uses cobalt-60 in its radiotherapy treatments for cancer patients. Cobalt-60 has a half-life of 7
NeTakaya

Answer:

We have 197 g of Co-60 after 18 months.

Step-by-step explanation:

We can use the decay equation.

M_{f}=M_{i}e^{-\lambda t}

Where:

  • M(f) and M(i) are the final and initial mass respectively
  • λ is the decay constant (ln(2)/t(1/2))
  • t(1/2) is the half-life of Co
  • t is the time at the final amount of m

M_{f}=228e^{-\frac{ln(2)}{7} 1.5}    

M_{f}=197\: g    

<u>Therefore, we have 197 g of Co-60 after 18 months.</u>

I hope it helps you!

You are researching two glaciers.the first glacier flows at a rate of 75 meters in 3 days.the second glacier flows at a rate of
podryga [215]

Answer:

1.3\ days

Step-by-step explanation:

step 1

Find the units rate of the first glacier

\frac{75}{3}=25\frac{meters}{day}

using proportion  

\frac{25}{1}\frac{meters}{day}=\frac{200}{x}\frac{meters}{days}\\ \\x=200/25\\ \\x=8\ days

step 2

Find the units rate of the second glacier

\frac{107.5}{5}=21.5\frac{meters}{day}

using proportion  

\frac{21.5}{1}\frac{meters}{day}=\frac{200}{x}\frac{meters}{days}\\ \\x=200/21.5\\ \\x=9.3\ days

step 3

Find the difference

9.3\ days-8\ days=1.3\ days

What is the solution to 2(-4x+1)=2/3(x+2)
Rzqust [24]

Hello!

The answer to your problem is: x=1/13

<u>Simplify both sides of the equation</u>

(2)(-4x)+(2)(1)=(2/3)(x)+(2/3)(2) (Distribute)

-8x+2=2/3x+4/3

<u>Subtract 2/3x from both sides</u>

-8x+2-2/3x=2/3+4/3-2/3x

-26x+2=4/3

<u>Subtract 2 from both sides</u>

-26/3x+2-2=4/3-2

-26/3=-2/3

<u>Multiply both sides by 3/(-26)</u>

(3/26)*(-26/3x)=(3/-26)*(-2/3)

<u>Get your answer</u>

x=1/13

Hope This Helps!

F(x) = 2x^2 - 3x, calculate f(x+h)-f(x) / h
kvasek [131]
First plug in (x+h) for x in the function.
f(x+h)= 2(x-h)^2-3(x-h) = 2(x^2-2xh+h^2)-3x-3h =
2x^2-4xh+2h^2-3x-3h - 2x^2 +3x =
(-4xh +2h^2-3h)/h
-4x +2h-3
