Answer:
Step-by-step explanation:
The speed is 212 miles per hour. The velocity is the same, but it has direction. So if up is positive and down is negative, then the velocity is -212 miles per hour.
Answer:
At 2:00 there will be 38,400 bacteria.
Step-by-step explanation:
600/150 = 4
2400/600 = 4
So, the bacteria quadruples every half hour.
At 1:30, there will be 2400*4 = 9600.
At 2:00, there will be 9600*4= 38400
Answer:
490 devided by 4 is 122.5 which is the amount Bradley payed per shirt, Calvin only payed 50 dollars per shirt. No the pay is not the same and the difference is 72.5

Answer:
A. 60 feet B. 7200 ft²
Step-by-step explanation:
A. Find the length of the corral along the river that will give the maximum area
To find the length of the corral that will give the maximum area, we differentiate A with respect to x and equate it to zero.
So, dA(x)/dx = d[x(240 - 2x)]/dx
= (240 - 2x)dx/dx + xd(240 -2x)/dx
= 240 - 2x -2x
= 240 - 4x
So, dA(x)/dx = 0
240 - 4x = 0
4x = 240
x = 240/4
x = 60 feet
B. Find the maximum area of the corral
The maximum area at x = 60 feet is
A(x)=x(240−2x)
A(60)=60(240−2(60))
A(60) = 60(240 - 120)
A(60) = 60(120)
A(60) = 7200 ft²
