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.
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.
Answer:
Step-by-step explanation:
Answer D I just fot it right on my test
35 + 0.05m = 50 + 0.01m <== ur equation
0.05m - 0.01m = 50 - 35
0.04m = 15
m = 15/0.04
m = 375.....u need to send 375 text messages for the plans to be equal
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)
