The answer is 87,455
P(x) = P(0) * nˣ
P(x) - the final population after period x
P(0) - the initial population
n - the growth factor in decimal
x - period of time
x = 3 hours
P(3) = 25,143
P(0) = ?
n = 100- 34% = 66% = 0.66
P(x) = P(0) * nˣ
25,143 = P(0) * 0.66³
25,143 = P(0) * 0.287496
P(0) = 25,143 / 0.287496
P(0) ≈ 87,455
Answer:
I think the answer is C
Step-by-step explanation: It could also be B
but then again it could be
y = -
x - 1
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange - 7x + 5y = 12 into this form
add 7x to both sides
5y = 7x + 12 ( divide all terms by 5 )
y =
x +
← in slope- intercept form
with slope m = 
given a line with slope m then the slope of a line perpendicular to it is
perpendicular slope = -
= - 
The partial equation of the perpendicular line is
y = -
x + c
to find c substitute (- 7, 4 ) into the partial equation
4 = 5 + c ⇒ c = 4 - 5 = - 1
y = -
x - 1 ← in slope- intercept form
0.004 is one tenth of 0.04 or 0.04 is ten times 0.004
