I think it’s b cos u minus 43 and your left with 48x and 47x so divide by 47 and you get 1 point something x = to x so yeah probably none because no number will make that work so it’s b

What is the halflife

blagie [28]

To model half-life, use the formula $A(t)=A_0 (\dfrac{1}{2})^{ \frac{t}{t_{1/2}}$ . Here, $A(t)$ is the amount remaining after a length of time $t$ . $A_0$ is the amount that you start with. $t_{1/2}$ is the half-life. You plug in 50 for $t_{1/2}$ , 10 for $A_0$ , and 25 for $t$ . You get $A(t)=10( \frac{1}{2})^{25/50} = 10( \frac{1}{2})^{1/2} = 7.07 \ grams$ .
