A population of bacteria is growing at a rate of 20% per hour. If the population starts at 320, what is it an hour later?

384.

Step-by-step explanation:

The population is given by the expression;

Where;

Y(t) is the number of bacteria at time, t.

P is the starting amount.

r is the growth rate.

Given that, P = 320, r = 20% = 0.2, t = 1

Substituting the parameters into the equation;

Y(1) = 320 * 0.2¹

Y(1) = 320 * 0.2

Y(1) = 64.

Therefore, the population of bacteria increases hourly by 64.

An hour later; 320 + 64 = 384.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
