The vertices of the image of GHJK after a translation are given. Choose the vector that describes the translation.

Lady_Fox [76]

Answer:

Option B

Step-by-step explanation:

Let's take a vertex G of quadrilateral GHJK to understand the rule for the translation,

From the graph attached,

Coordinates of G → (-5, 5)

Coordinates of the image point G' after the translation → G'(-5, 5)

Let the point G is translated 'a' units to the right and 'b' units down,

Rule for this translation,

G(x, y) → G'(x + a, y - a)

By this rule,

G(-5, 5) → G'(-5 + a, 5 - a)

-5 + a = -5 ⇒ a = 0

5 - a = 5 ⇒ a = 0

Therefore, vector that defines the translation will be,

<0, 0>

Option B is the the correct option.

The number of bacteria in a culture increases continuously and rapidly when put under a heat source. a culture containing 20 bac

Len [333]

Answer:

The answer is 14.46%

Step-by-step explanation:

Given is : A culture containing 20 bacteria multiplies to 117,360 in one minute.

Let A0 be initial bacteria count = 20

Let A be final bacteria count = 117360

Time = 60 seconds

R = rate

Formula to be used = $A=A0e^{rt}$

$117360=20e^{r*60}$

$5868=e^{60r}$

Taking log function (ln) on both sides.

$ln(5868)=ln(e^{60r} )$

$60r=8.677$

Hence, r = 0.1446 and in percentage it is 14.46%
