Answer:
20
Step-by-step explanation:
8 : 2/5 =
8 * 5/2 =
4 * 5 =
20
Given exponential function
f(x)= 
Where x is the number of years
f(x) is the number of tuna in thousands
To find out when number of tuna is 50 thousand , we plug in 50 for f(x) and solve for x

Divide by 230 on both sides

Take ln on both sides


Divide by ln(0.881) on both sides
x = 
x= 12.04
Year = 1974 + 12.04 = 1986
so in 1986 there will be 50 thousand tuna.
Answer: -7 less than or equal to x less than or equal to 5
Step-by-step explanation:
It start at -7 and end at 5 which is the x axis
1) 6.6 * 3.3 = 21.78
2) (10^ - 2 )*(10^ - 4) = 10 ^ ( -2 - 4) = 10 ^ - 6
3) result: 21.78 * 10 ^ - 6
4) to convert to standard form run the period on space to the lef and multiply the ten base by 10 =>
2.178 * 10 ^ - 5
Answer: 2.178 * 10 ^ - 5
