12g + 21 and( 3×4g=12g+3×7=21)
12g+21 and 12g+21,,
Answer:
8 hours
Step-by-step explanation:
rental fee = 12 + 4/hr
spent = 44
44 = 12+4(hr)
32 = 4(hr)
32/4 = hr
hr = 8

Answer: 2 11/12
Step-by-step explanation: 3 1/3+−2 1/4+1 5/6
10/3−2 1/4+1 5/6
10/3−9/4+1 5/6
13/12+1 5/6
13/12+11/6
35/12
2 11/12
Y=-x^2-2
dy/dx=-2x and d2y/dx2=-2
Since acceleration is a negative constant, when the velocity equals zero, it will be an absolute maximum for y(x)
dy/dx=0 when -2x=0, x=0
y(0)=-2
So the vertex is at the absolute maximum, which is the point (0,-2)
