Let u = 4x^2, then y=e^u
dy/dx= dy/du x du/dx
dy/dx= 8xe^4x^2
Then do product rule to find d2y/dx2
d2y/dx2 = 64 x^2 e^4x^2 + 8e^4x^2
Substitute d2y/dx2 and dy/dx into the equation then will get equal to zero

Answer:
80 ft
Step-by-step explanation:
Let the height of the light house be x feet.

Percent means parts out of 100
so
1/5=0.20
chris+em+jam=100%=1
0.20+0.27+jam=1
0.47+jam=1
minus 0.47 both sides
jam=0.53
jam=53/100
jam=53%
jamie ate 53%
Answer:
-1/3
Step-by-step explanation:
(-2, 5) and (1, 4)
Slope:
m=(y2-y1)/(x2-x1)
m=(4-5)/(1+2)
m=(-1)/3
m= -1/3
