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.
Y=-13 since the line includes all coordinates of x but only coordinates containing y=-13
Answer:
C) 2400
Step-by-step explanation:
Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.
Computers = 10
Printers = 3
Scanners = 5
Telephone = 8
Copiers = 2
Possible outcome = 10 x 3 x 5 x 8 x 2 = 2400
The first answer is 2.5 and I don’t know the last two sorry
The answer is
A. 3x - y= -7
