Scientists measure a bacteria population and find that it is 10,000. Five days later, they find that the population has doubled. Which function f could describe the bacteria population d days after the scientists first measured it, assuming it grows exponentially? a
f(d)=10,000*2^d

b
f(d)=10,000*(5sqrt2)^d

c
f(d)=10,000*(1\5sqrt2)^d

d
f(d)=10,000*2^5d

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b

d 600 because 15*10*2=300

300+300=600
