It would be 28:20
7=5=12
48/12=4
7x4=28
5x4=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:
D. Only 16 and 21
Step-by-step explanation:
Plug in 16 and 21 to replace the x and the answer will be bigger than 24.
Answer:
86cm³
Step-by-step explanation:
The area of the triangle is 1/2(b)(h)*2. The 1/2 and 2 cancel out as we’re doubling the small triangle to make the big triangle. Then you just multiply it times the length of the prism. So the formula ends up:
2.5*4.3*8=86cm³
