The two equations for which the given number of fist is satisfied when x = 8 is plugged in are:
<span>P(x) = 13x^2 – 10x + 350
and
</span><span>P(x) = 18x^2 + 10x + 300
Now, we can only decide which is correct if we have additional information, specifically if we know the number of fish initially. If it is 350, option B is correct and if it is 300 then option D is correct.</span>
The answer is x = 9/13
Hope in helped
Answer:
y = 5 cos ((2π/3)x - 2) + 2
Step-by-step explanation:
Cosine function takes a general form of y = A cos (Bx + C) + D
Where
A is the amplitude
2π/B is the period
C is the phase shift ( if -C, then phase shift right, if +C phase shift left)
D is the vertical displacement (+D is above and -D is below)
Given the conditions of the function to build and the general form, we can write:
** Note: period needs to be 3, so 2π/B = 3, hence B = 2π/3
Now we can write:
y = 5 cos ((2π/3)x - 2) + 2
first answer choice is right.

Have a nice day!
Step-by-step explanation:
cos = adj/hyp
cos 24°= hcm/ 13cm
13 cos 24°= h
