A culture started with 2000 bacteria. After 4 hours, it grew to 2,200 bacteria. Predict how many bacteria will represent after 9

S_A_V [24]

Y=2000* $e^{k*t}$

2200=2000* $e^{k*4}$

$e^{k}= ( \frac{22}{20} )^{(1/4)}$ 

so,
y at t=8 is 2000*( $( \frac{22}{20} )^{(1/4)}$ )^8
y = 2000(22/20)^2=2000*1.21=2420 thats the answer i hope.

Solve the quadratic equation by completing the square. x²–2x-12=0

inn [45]

Answer:

$(x-1)^2-13=0$

$x = \sqrt{13}+1$

Step-by-step explanation:

Completing the square is a method of rewriting a quadratic equation in the standard form such that it is in vertex form. The first step is to group the linear and quadratic terms, then factor out the coefficient of the quadratic term. After doing so, complete the square, add a value such that the linear and quadratic terms form a perfect square trinomial. Do not forget to balance the equation. The final step is to simplify.

$x^2-2x-12=0$
