A certain population of bacteria has an average growth rate of 2%. The formula for the growth of the bacteria's population is A=Po⋅1.02^t, where Po is the original population and t is the time in hours.

If you begin with 200 bacteria, about how many bacteria will there be after 100 hours?
A. 1,449
B. 272
C. 20,000
D. 7

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)

the correct answer is c
