Urgent assistance needed.

kira draws a segment and labels the endpoints e and f. she uses a compass and straightedge to construct a segment congruent to ef .

drag and drop the steps kira uses in order from start to finish.

Kira will use 2,5,1,4 and 3.

Step-by-step explanation:

Diagrams were attached below.

To draw a congruent segment we will:

1.Mark the point lets call it G.

2.Then with the help of compass measure the length of EF.

Putting the compass point on E and pencil point on F.

3.Now we have to draw an arc by putting the compass point on G.

4.We have to mark any point on the arc lets say that H.

5.With the help of straightedge we will join both G and H.

linearly: 8560 bacteria

exponentially: approximately 75233 bacteria

step-by-step explanation:

assuming it is not exponential (we would have some really complicated logarithms), let's say it is linear. then, after 5 hours, it increased by 1200 bacteria, so every hour it increases by 240 bacteria. this means that after 19 hours, we get 19 * 240 + 4000 bacteria or 3800 + 760 + 4000 = 7800 + 760 = 8560 bacteria.

because it says round your answer, i will do this exponentially (with a calculator, of course). first, we need to find how much it multiplies by every hour, by taking the 5th root of 52/40 or 13/10. this is approximately 0.167. we still need to add 1 to this, because we are multiplying by that number, not adding that amount of the number. now, we just calculate 4000 * (1.167)^19. use a calculator to get approximately 75232.6, or 75233.
