The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
Just need to take partial derivatives of the function with respect to x and y then plug in the point coordinates
dT/dx = -38x/(2 + x^2 + y^2)^2dT/dy = -38y/(2 + x^2 + y^2)^2 (only difference is the y in the numerator)
so at point 1,2dT/dx = -38/49 = -0.7755dT/dy = -76/49 = -1.551
I believe it’s 12000 because 30x50=1500 1500x2=3000 now 3000x4=12000
Answer:
(+5) and (-9)
Step-by-step explanation:
(+5) + (-9) = -4
(+5) × (-9) = -45
Answer:
s/2πh =r
Step-by-step explanation:
s=2πrh
Divide both sides by 2πh to isolate r
s/2πh =2πrh /2πh
s/2πh =r
