Answer:

6. Bacteria tend to grow very fast in a petri dish at first because of unlimited food and then begin to die out due

to competition. In a certain culture, the number of bacteria is givenby N(f) =1f +92t+.625' where /

represents the hours since 625 bac,teriawere introduced to the Petri dish. Determine the *={TlgX9"t

of bacteria that occur in the dish.

Step-by-step explanation:

t= -92/-2(2) =23

N (23) power 2 +92(23) + 625 =1628

What is the slope <br> y = (34/4)x + 3

statuscvo [17]

Answer:

The slope is 17 / 2.

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Find the values of m and b using the form y=mx+b.

m=17 / 2

b=3

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: 17 / 2

y-intercept: 3

Triangle DEF is the image of triangle ABC after a sequence of transformations. After you reflect ABC in the y-axis, what must yo

Artemon [7]

Answer:

Step-by-step explanation:

After reflection about y-axis, A'B'C' must be translated down 6 units to create image DEF.

ABC and DEF are congruent due to the following common properties of reflections and translations.

1. does not change the nature of geometric elements, i.e. maps a line to a line, a segment to a segment, etc.

2. preserve lenths of segments.

3. preserves angles

By the congruent theorem of SSS, the two triangles are congruent.
