The half-life of iodine-123 is about 13 hours. You begin with 38 grams of iodine-123.

qaws [65]

Half-life, h = 13 hours
Mass initial, a = 38 g
B=base for half-life = 2
(a)
I(t)=a*B^(-t/h)=a*(B^(1/h)^(-t)=a*(B^(-1/13))^t
Substituting values,
I(t)=38*(2^(-1/13))^t
a=38 g
b=2^(-1/13)=0.9480775 (approximately)
=>
I(t)=38*0.9480775^t

(b) I(t)=7
solve
I(t)=7=38*0.948077^t
Take log on both sides and solve for t
t=log(7/38)/log(0.948077)
=31.727 hours.

Check: I(31.727)=38*9.948077^(31.727)=7.000 g ok

What is the linear function equation represented by the graph?

Lana71 [14]

Answer:

$f(x) = \frac{1}{3}x - 4$

Step-by-step explanation:

Determine the slope value, m, and the y-intercept value, b.

Find the slope, m using two points, (0, -4) and (3, -3).

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-3 -(-4)}{3 - 0} = \frac{1}{3}$

m = ⅓.

The y-intercept (b) = -4 (this is where the y-axis is intercepted by the line)

To get the linear function equation, substitute m = ⅓, and b = -4 into $f(x) = mx + b$

The linear function equation would be:

✔️ $f(x) = \frac{1}{3}x + (-4)$

$f(x) = \frac{1}{3}x - 4$
