I would think its $42 but thats just my op ion <span />
Differentiating implicity gives
g'(x) + xcos(g(x))(g'(x)) + sin(g(x)) = 2x
g'(x)[1 + xcos(g(x))] = 2x - sin(g(x))
g'(x) = [2x - sin(g(x))] / [1 + xcos(g(x))]
<span>g'(0) = -sin(g(0))
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

the water in a fish tank is decreasing at a rate of 2 inches per hour
Rate of change is the derivative
Rate of change in height with respect to time is 2 inches per hour
so
(a)
unit is feet^2 so its area
the unit of area is always units^2
so da/dt is the rate of change in area with respect to time
(b)
r is the radius
so dr/dt is the rate of change in radius with respect to time
Radius is decreasing at the rate of 40 cm per minute
(c)
v is the volume . the unit of volume is always cubic units
so dv/dt is the rate of change in volume with respect to time
Volume is decreasing at the rate of 10 meter cube per second
Answer:
37in.^2
Step-by-step explanation:
So if the triangles at the top have a hypotenuse of 5, and a length of 4, then doing reverse Pythagorean theorem, you find out that the width is 3.. so reverse of that for this problem would be and if we plug it in, we get 25 -16=9 and the square root of 9 is 3. so if we find the are of the triangle, 3*4*1/2=6 and there are 2 triangles so 12 for both triangles. The square is 5*4=20. and the smaller triangles on the side are 1*5*1/2=2.5, and there are 2 traingles so 2.5*2= 5. So 5+20+12=37. You can do this on most calculators, and please put my answer as the brainliest.✌
