<u>Answer:</u>

t = 6.3 days

<u>Step-by-step explanation:</u>

The amount of initial mass is irrelevant when finding the half-life since the remaining mass is always 1/2 of the initial mass.

\frac { 1 } { 2 } = e ^ { ( - 0 . 1 0 9 2 t ) }

Taking l n on both the sides to get:

ln \frac { 1 } { 2 } = -0.1092t

t = \frac { l n \frac { 1 } { 2 } } { -0.01092}

t = 6.3475

t = 6.3 days

write a linear equation that intersects y=x^2 at two points. Then write a second linear equation that intersects y=x^2 at just o
Liula [17]

We know that y = x^2 is a parabola, concave up, with vertex in the origin (0,0)

So, we may use three horizontal lines for our purpose: any horizontal line above the x axis will intersect the parabola twice. The x axis itself intersects the parabola once on the vertex, while any horizontal line below the x axis won't intercept the parabola.

Here's the examples:

  • The horizontal line y = 4 intercepts the parabola twice: the system y = x^2,\ y = 4 is solved by x^2=4 \implies x = \pm 2
  • The horizontal line y=0 intercepts the parabola only once: the system is y=x^2,\ y=0 which yields x^2=0\implies x=0 which is a repeated solution
  • The horizontal line y=-5 intercepts the parabola only once: the system is y=x^2,\ y=-5 which yields x^2=-5 which is impossible, because a squared number can't be negative.
