X = 24 *(* represents degrees as I’m on mobile)
A straight line is 180*.
The 156* angle and the x* angle make up a straight line, so 156*+x*=180* Subtract 156 from both sides to get x=24*
The area of the surface is 144.708
The equation of the given surface is,
z=g(x,y)=xy
Solving the partial derivatives,
∂g∂x=y,∂g∂y=x
Substituting to the formula
S=∬√1+( ∂g∂x)2+(∂g∂y)2dA
Thus,
S=∬√1+(y)2+(x)2dAS=∬√1+x2+y2dA
The region in the XY-plane is defined by the intervals 0≤θ≤2π,0≤r≤4
Converting the integral into polar coordinates,
S=∫2π0∫40√1+r2rdrdθ
Integrating with respect to r
S=∫2π0[13(1+r2)32]40dθ
S=∫2π0(17√173−13)dθ
Integrating with respect to θ
S=(17√173−13)[θ]2π0
S≈144.708

Answer:
y = -2/5x - 6
Step-by-step explanation:
Slope intercept follows the y = mx + b, which m is the slope, and b is the y intercept.
1. Find the slope:
The formula for slope is the change in y/ over the change in x. Or you can say rise/run.
In other words you can take any of those 2 dots, first count them to the other dot, which is -2, then count horizontally, which is 5, so the slope is -2/5
Another way:
Another way is to take any two points, like (-10, -2), and (-5, -4).
Then we can do -4 -(-2)/-5 -(-10), which is -2/5.
So the equation we have so far is y = -2/5x + b
2.Find the y intercept
Based on the graph, the y intercept is -6, so we get
y = -2/5x - 6
