Find the slope of the graph y=5sinx at x=pi/2

1 answer:

5 0

$\bf y=5sin(x)\qquad \cfrac{dy}{dx}=5cos(x)
\\\\
x=\frac{\pi }{2}\implies \cfrac{dy}{dx}=5cos\left( \frac{\pi }{2}\right)\to 5\cdot 0\to 0$

Answer:

$\frac{ {x}^{2} }{y(x - y)} + \frac{ {y}^{2} }{ - x(x - y)}$

$\frac{ {x}^{2} }{y(x - y)} - \frac{ {y}^{2} }{x(x - y)}$

$\frac{ {x}^{2} \times x - {y}^{2} \times y}{xy(x -y)}$

$\frac{(x - y)( {x}^{2} + xy + {y}^{2}) }{xy(x - y)}$

$\frac{ {x}^{2} + xy + {y}^{2} }{xy}$

Answer:

x=6

Step-by-step explanation:

3(x+2) = 24

Divide each side by 3

3/3(x+2) = 24/3

x+2 = 8

Subtract 2 from each side

x+2-2 = 8-2

x=6

The value of x would be 60 degrees

explanation

===============================
the triangle has one missing angle that would be congruent to x since they are corresponding angles which means they are congruent.

We know that the triangle has to add up to 180 degrees. We add the 2 angles and get 120 degrees. We subtract 120 degrees from 180 to find the 3rd missing angle that is congruent to x degrees. 180-120=60 degrees. If 60 degrees is corresponding to x degrees, therefore, x should be equal to 60 degrees.

Hope this helps :)
