Assuming you want to find x?
You know that the angles at C and B have to be the same (6x) because it’s an isosceles triangle (as indicated by the lines going through AC and AB), and angles in a triangle add to 180*

So 3x + 6x + 6x = 180*
15x = 180*
x = 180*/15
x = 12*

Plzzz help asapppppp what is the inverse of f if f(x)=^3 sqrt x-5
jasenka [17]

Hello from MrBillDoesMath!

Answer:

The first choice, y = x^3 + 5


Discussion:

Let

y = (x-5) ^ (1/3)

To find the inverse, sway x and y and then solve for y:

x = ( y - 5 )^(1/3)         =>             cube both sides

x^3 = y - 5                  =>             add 5 to both sides

x^3 + 5 = y


So the inverse is  x^3 + 5, which is the first choice


Thank you,

MrB

Westkost [7]
Answer by BlueSky06

The equation described above can also be written as,                    y = -x² + 100x + 4000To get the number of notebooks that will give them the maximum profit, we derive the equation and equate to zero.                  dy/dx = -2x + 100 = 0The value of x from the equation is 50. Then, we substitute 50 to the original equation to get the profit.                    y = -(50^2) + 100(50) + 4000 = 6500Thus, the maximum profit that the company makes is $6,500/day.
