Answer:

\large{ \tt{☄ \: STEP - BY- STEP \: EXPLANATION}} :

  • We are provided the diameter of circle ( d ) i.e 13 cm & value of pi ( π ) i.e 3.143. We are asked to find out the circumference of the given circle ( C ).

\large{ \tt{✎ \: LET'S \: START} }:

\boxed{ \large{ \tt{❃ \: Circumference \: of \: a \: circle = \pi \: d}}}

- Plug the given values & Multiply 3.142 by 13

\large{ \tt{↬ \: 3.142 \times 13}}

\boxed{ \large{↬ \tt{40.846 \: cm}}} [ Don't forget to write the units i.e cm ]

\boxed{ \boxed{ \tt{⟿ \: OUR \: FINAL \: ANSWER:  \boxed{ \underline{ \tt{40.846 \: cm}}}}}}

1.Arsenic-74 is used to locate brain tumors. It has a half-life of 17.5 days. 90 mg wereused in a procedure. Write an equation t
Sophie [7]

1)\text{   }N_t\text{ = 90\lparen}\frac{1}{2})^{\frac{t}{17.5}}

2) 5.625 mg will be left

Explanation:

1) Half-life = 17.5 days

initial amount of Arsenic-74 = 90 mg

To get the equation, we will use the equation of half-life:

\begin{gathered} N_t\text{ = N}_0(\frac{1}{2})^{\frac{t}{t_{\frac{1}{2}}}} \\ where\text{ N}_t\text{ = amount remaining} \\ N_0\text{ = initial amount} \\ t_{\frac{1}{2}\text{ }}\text{ = half-life} \end{gathered}N_t\text{ = 90\lparen}\frac{1}{2})^{\frac{t}{17.5}}

2) we need to find the remaining amount of Arsenic-74 after 70 days

t = 70

\begin{gathered} N_t=\text{ 90\lparen}\frac{1}{2})^{\frac{70}{17.5}} \\ N_t\text{ = 5.625 mg} \end{gathered}

So after 70 days, 5.625 mg will be left
