The number of bacteria on a piece of toast triples every
Illusion [34]

Answer:

You begin with 1 bacteria, and after 1 hour it has tripled so you now have 1 x 3=3.

Next hour, it triples again so you now have 1 x 3 x 3=9

You can see the pattern shows that the number of bacteria is multiplying every hour by a factor of 3. An exponent denotes how many times we are multiplying a number by itself, for example: 34 means we are multiplying the number 3 a total of 4 times (3 x 3 x 3 x 3).

Therefore the question is requiring us to triple the number of bacteria every hour for 24 hours, which means we are multiplying by 3 a total of 24 times. This gives us:

n x 324 where n is the number of bacteria you begin with.

Since you begin with 1 bacteria, the solution is 1 x 3 to the power 24 and u will get ur answer

Identify the pair of figures in which the second figure is a translation of the first figure​
Nadya [2.5K]

Answer:

The first pair of figures would be a translation.

Step-by-step explanation:

A translation is a transformation that involves the shift or slide of a figure in the coordinate plane.  This movement will only be either horizontal, vertical or a combination of both.  The second and third set of figures given include not only a shift, but a reflection and rotation as well.  The only set of figures that has been moved horizontally and/or vertically is the first set.

Find the inverse of y=5x+3
seraphim [82]

Answer:

f^{-1}(x) = \frac{x-3}{5}

Step-by-step explanation:

Rearrange the equation making x the subject

y = 5x + 3 ( subtract 3 from both sides )

y - 3 = 5x ( divide both sides by 5 )

\frac{y-3}{5} = x

Change y to x then

f^{-1}(x) = \frac{x-3}{5}
