After a special medicine is introduced into a petri dish full of bacteria, the number of bacteria remaining in the dish decrease
Crazy boy [7]

Answer:

  0.17

Step-by-step explanation:

The function can be rewritten as ...

  B(t) = 9300·((1/2)^6)^t = 9300·(1/2)^(6t)

In order to multiply the number of bacteria by 1/2, the value of the exponent 6t must be equal to 1:

  6t = 1

  t = 1/6 ≈ 0.166667 ≈ 0.17

The culture loses half its size every 0.17 seconds.

PLEASE HELP!
Vlad [161]

Answer:

Option A. ∠C and ∠C'' are congruent after both the translation and the dilation

Step-by-step explanation:

we know that

The translation is a rigid transformation. After the translation the image and the pre-image are congruent

The dilation is a non rigid transformation. After the dilation the image and the pre-image are similar

Remember that

If two figures are similar, then its corresponding angles are congruent and the ratio of its corresponding sides is proportional

If two figures are congruent, then its corresponding angles and corresponding sides are congruent

therefore

∠C and ∠C'' are congruent after both the translation and the dilation

Answer:

  (2x -3)(2x -1)

Step-by-step explanation:

We have filled in the X-diagram so the side values have a product equal to the top value, and a sum equal to the bottom values (the middle term).

We're not sure how you've been taught to split the leading coefficient to arrive at the factors shown on the right.
