What's the answer?????????????
Taya2010 [7]

Answer:

BD = 12 :)

Step-by-step explanation:

Alright, we'll need the Pythagorean theorem for this!

So, the length of AC is 10. That means the lengths of AD and DC are both half of that, which is 5 :)

DC = 5

We already know that BC = 13, so we can plug in these values into the pythagorean theorem for the right triangle BDC:

BD^2 + DC^2 = BC^2

BD^2 + 5^2 = 13^2

BD^2 + 25 = 169

BD^2 = 169 - 25 = 144

BD = √144 = 12 :)

The number of bacteria in a culture is expected to grow 82% per hour over the next several hours. The predicted change in the nu
Advocard [28]
If my simplification is valid the answer is:

1.4 % growth each minute

I don’t feel like the representation
P = 120(1.82) is important in this certain problem.

So P the predicted number of bacteria is not practical with this problem.

Use the 82% per hour and divide it by 60 because there are 60 minutes in an hour.

When doing this you find the rate in which bacteria grows which is about 1.4%.

The prediction is about 1.82 percent for 120 something it’s not clarified, but I’m guessing that’s minutes.

So you can prove that the prediction is over the rate in which bacteria grows per minute.
