I don’t think it’s -3, you should multiply to get 168!

Answer:

  60

Step-by-step explanation:

The exterior angles of the polygon are the supplement of the interior angles, so are ...

  180° -174° = 6° . . . . measure of each exterior angle

The sum of exterior angles is 360°, so ...

  n(6°) = 360°

  n = 360°/6° = 60

The polygon has 60 sides.

Further mathematics: Find the derivative of the function x^2 y + (xy)^3 +3x=0 at (-1 , 3)​
vesna_86 [32]

Answer:

3.

Step-by-step explanation:

Implicit differentiation:

x^2 y + (xy)^3 + 3x = 0

x^2 y + x^3y^3 + 3x = 0

Using the product rule:

2x* y + x^2*dy/dx + 3x^2 y^3 + x^3* (d(y^3)/dx) + 3 = 0

2xy + x^2 dy/dx + 3x^2 y^3 + x^3* 3y^2 dy/dx + 3 = 0

dy/dx(x^2 + 3y^2x^3) =  (-2xy - 3x^2y^3 - 3)

dy/dx=  (-2xy - 3x^2y^3 - 3) / (x^2 + 3y^2x^3)

At the point (-1, 3).

the derivative =  (6 - 81 - 3)/(1 -27)

= -78/-26

=  3.

Please help me with my last question no wrong answers plsss

Answer:

(2/5, 9/5)

Step-by-step explanation:

To find the solutions, we are given the value of y in terms of x: y = 2x + 1. We can plug this into the circle equation to get:

(x - 1)^2 + (2x + 1 - 1)^2 = 1

Now, we can expand and simplify:

x^2 - 2x + 1 + (2x)^2 = 1

x^2 - 2x + 1 + 4x^2 = 1

5x^2 - 2x = 0

Now, we can factor:

x(5x - 2) = 0

And, using the zero product property, we get two equations which we can solve:

x = 0

5x - 2 = 0

5x = 2

x = 2/5

Since x is 0 in the first solution, we use the other solution and plug it into the equation y = 2x + 1 to find y:

y = 2(2/5) + 1

y = 4/5 + 1

y = 9/5

This means the coordinates of the point is (2/5, 9/5)
