What is the length of the missing leg? If necessary, round to the nearest tenth.
Mekhanik [1.2K]

<u>Answer:</u>

  • The length of the hypotenuse is 36 miles.

<u>Step-by-step explanation:</u>

<em>We can solve for 'a' using Pythagoras theorem. Let's solve it.</em>

  • 39² = a² + 15²
  • => 1521 = a² + 225
  • => a² = 1296
  • => a = 36

Hence, the length of the hypotenuse is 36 miles.

Hoped this helped.

To begin a bacteria study a petri dish had 2200 bacteria cells every hours since the number of cells has increased by 3.8% let t
WINSTONCH [101]

Answer:

Therefore the required relationship is

y = 2000(1.038)^t

Step-by-step explanation:

Given that, to begin a bacteria study a petri dish had 2200 bacteria cells every hours.

The growth of bacteria is in exponential.So we use the following formula

A=P(1+r)^n

A= Total amount =y = the number of bacteria cell

P= initial value = 2000

r= rate of increase = 3.8%= 0.038

n = time = t

Putting the all values

y=2000(1+0.038)^t

\Rightarrow y = 2000(1.038)^t

Therefore the required relationship is

y = 2000(1.038)^t
