Answer:
2,340,208.5 or 2,340,209
Step-by-step explanation:
You could answer this by multiplying the current population of 800,000 by 1.05 (1.05 represents the annual growth rate of population) and do that 22 times. But that would take a while.
we got 1.05 because the formula says that y = a( 1 + r ) power t
for a we will give it 1
so y = 1 ( 1 + 0.05) power t
it will give us 1.05
to do this faster, you would first calculate (1.05)22and then multiply this by 800,000.
So, 800,000 x (1.05)22 = 2,340,208.5 or 2,340,209
Sn = n/2 ( a1+an)
= 6/2 (10+85)
= 3 (95)
= 285
Answer:
Yes
Step-by-step explanation:
SI=PRT/100
SI=A-P
R=SI×100/P×T
T=SI×100/R×T
P=SI×100/R×T
<span>Phil and Matt made cookies for a fundraiser at their high school. Phil worked more than Matt. Phil production was 25% more than Matt production. Matt was behind on the quantity made by Phil. The cookies sold for $0.25 each. After the sale, 20% of the combined production of their cookies remained.</span>
<u>Answer-</u>
<em>The exponential function that satisfies the given conditions is 
</em>
<u>Solution-</u>
This can be represented as exponential decreasing function,
Where,
-
a = starting amount = 67
- r = rate = 0.47% = 0.0047
- t = week
Putting the values,
Therefore, the exponential function that satisfies the given conditions is
