Answer:
(-1, 19) and (3, -81)
Step-by-step explanation:
f(x) = 2x³ − 6x² − 27x
f'(x) = 6x² − 12x − 27
-9 = 6x² − 12x − 27
0 = 6x² − 12x − 18
0 = x² − 2x − 3
0 = (x + 1) (x − 3)
x = -1 or 3
f(-1) = 19
f(3) = -81
The points are (-1, 19) and (3, -81).
Y=14x
Compare with general form:
y=kx
Where k is the constant of proportionality.
Here k=14
So 1 unit increase in x will bring 14 times increase in y.
There is a direct relation between x and y.
Answer: Yes
Answer:
3^9 * 3^7
Step-by-step explanation:
I don't really know how to explain it lol
I found 37.4 m.
I tried using trigonometry and the tangent of an angle (in this case 39°):
This is how i got the result, i hope it is correct!
