Heyy it’s 1:50! you would put the original two numbers in a ratio 16:800 divide by 8 and get 2:100 then divide by 2 and get 1:50!
Answer:
698 fishes
Step-by-step explanation:
Generally, we can represent an exponential growth function as;
y = a•(1 + r)^t
originally, there were 3 fishes
The original value in this case means a = 3
After 6 weeks, there were 31
31 in this case is y
r is the increase percentage or rate
t is the time
So, we have it that;
31 = 3•(1 + r)^6
31/3 = (1 + r)^6
10.33 = (1 + r)^6
ln 10.33 = 6 ln (1 + r)
ln 10.33/6 = ln (1 + r)
e^0.3892 = (1 + r)
1 + r = 1.476
r = 1.476-1
r = 0.476 or 47.6%
So the growth percentage or rate is 47.6%
For 14 weeks, we simply have the value of t as 14;
So ;
y = 3•(1 + 0.476)^14
y = 3(1.476)^14
y = 698 fishes
$1,047.50 so she has to pay that amount
Answer:
$5367.54
Step-by-step explanation:
9000 = P(1 + .03/12)^207*
9000 = P×1.676744643
P = 5367.54
*207 = 12 x 17.25
6x+3y=0
3x+3y=9
6x+3y=0
3y=9-3x
6x+9-3x=0
X=-3
3y=9-3x(-3)
Y=6
(X,y)=-3,6
