If i’m understanding this correctly -9 + -4 is equal to -13 so wouldn’t you just add 13 to make it 0?

sorry if this is confusing

Find dy/dx given that y = sin(cos(x))​
bazaltina [42]

Hi there!

\large\boxed{-sin(x)cos(cos(x))}

Use the chain rule:

f(g(x)) = f'(g(x)) · g'(x)

Thus:

dy/dx sin(x) = cos(x)

dy/dx cos(x) = -sin(x)

Use the chain rule format:

f(x) = sin(x)

g(x) = cos(x)

cos(cos(x)) · (-sin(x))

-sin(x)cos(cos(x))

andriy [413]

Answer:

\frac{5}{14} or 0.357142857143

Step-by-step explanation:

__________________________________________________________

\frac{2}{7}\div\frac{4}{5} = \frac{5}{14} because,

\frac{2}{7} = 0.285714285714

\frac{4}{5} = 0.8

0.285714285714 \div 0.8 = 0.357142857143

\frac{5}{14} = 0.357142857143

Help please if u can answer!:)
pentagon [3]

Answer:

ANGLE K IS 75 DEGREES

All the interior angles of a triangle ADD up to 180 degrees

lets add the angles!

6x-11+8x-29+3x-1

add like terms. all the x terms add up and all the constants as well

8x+6x+3x = 17x

-29-1-11 = -41

17x-41= 180 (-41 + 41 = 0 we do this to remove -41 from the left side of the equation to isolate x)

41+180 = 221

17x=221

221/17 = 13

x=13

so..

8 * 13 - 29 is the angle..

8*13 = 104

and 104-29 = 75

Angle K is 75 degrees! hope that helps..
