I am guessing that the correct form of equation
is:
f(x)
= 16,800(0.9)^x
where
x is the exponent of (0.9)
Since
we are looking for the original population and x stand sfor the number of years,
therefore x=0
substituting:
f(x) = 16,800(0.9)^0
Since (0.9)^0 would just be equal to 1. Therefore
the original population is
16,800.
Answer: B. 16,800
Answer:
c and d
Step-by-step explanation:
using the two angles in the triangle, 1 and 2, it can be 180- the sum of angles 1 and 2, which is c. using angle 4, it can also be 180 - the equation for angle 4
Answer:
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
Answer:
The original temperature was -18°F
Step-by-step explanation:
x°F + 24°F = 6°F
or, x°F = 6°F - 24°F
so, x°F = -18°F
Answer:
26
Step-by-step explanation:
Let x represent the missing number

Convert both fractions to improper fractions

Cross multiply


Subtract both sides by 1,575


Divide both sides by 15

x = 26
