A type of bacteria has a very high exponential growth rate of 80% every hour. If there are 10 bacteria, determine how many will
Lana71 [14]
<h3>There are 189 bacteria in 5 hours</h3><h3>There are 13382588 bacteria in 1 day</h3><h3>There are 10(1.8)^{168} bacteria in 1 week</h3>

<em><u>Solution:</u></em>

Given that,

A type of bacteria has a very high exponential growth rate of 80% every hour

There are 10 bacteria

<em><u>The increasing function is given as:</u></em>

y = a(1+r)^t

Where,

y is future value

a is initial value

r is growth rate

t is time period

From given,

a = 10

r = 80 \5 = \frac{80}{100} = 0.8

<em><u>Determine how many will be in 5 hours</u></em>

Substitute t = 5

y = 10(1 + 0.8)^5\\\\y = 10(1.8)^5\\\\y = 10 \times 18.89568\\\\y \approx 188.96

y = 189

Thus, there are 189 bacteria in 5 hours

<em><u>Determine how many will be in 1 day ?</u></em>

1 day = 24 hours

Substitute t = 24

y = 10(1 + 0.8)^{24}\\\\y = 10(1.8)^{24}\\\\y = 10 \times 1338258.84\\\\y = 13382588.45\\\\y \approx 13382588

Thus, there are 13382588 bacteria in 1 day

<em><u>Determine how many will be in 1 week</u></em>

1 week = 168

Substitute t = 168

y = 10(1 + 0.8)^{168}\\\\y = 10(1.8)^{168}

Thus there are 10(1.8)^{168} bacteria in 1 week

Calvin bought 6 ties for $19.50 each and three shirts for $23.50 each. how much did he spend?​
lions [1.4K]
The answer is $187.5 because you need to multiply 19.50 x 6 and that will equal 117.
$23.50 x 3 = 70.5. Add those two together and it will be $187.5

So, taking 149.98 and subtracting the non-taxable total, 26.95, you are left with 123.03, which to equal 10.07 would have to be multiplied by 0.0819, hence the sales tax is 0.0819.
