For this case we have the following equation:
 h = -16t2 + 32t + 6
 Deriving we have:
 h '= -32t + 32
 Equaling to zero:
 -32t + 32 = 0
 We clear the time:
 t = 32/32
 t = 1 s
 We are now looking for the maximum height:
 h (1) = -16 * (1) ^ 2 + 32 * (1) + 6
 h (1) = 22 feet
 Answer:
 
The ball reaches its maximum height in:
 
t = 1 s
 
The ball's maximum height is:
 
h (1) = 22 feet
 
option: 22 ft, 1 s

Answer:

Step-by-step explanation:

Area of the shaded region will be "(area of rectangle) - (area of triangle)"

Area of rectangle: 8 ft * 5 ft = 40 ft^2

Area of triangle: 1/2 * 3 ft (36 in) *  2.25 ft (27 in) = = 3.375 ft^2

40 - 3.375 = 36.625 ft ^2 = 5274 in^2

Rico earns a weekly salary of $750 and a 5% total Commission on his sales Sean earns a weekly salary of $1,100 and a 2.5% commis
NNADVOKAT [17]
To answer this item, we let x be the amount of sales for each of them. Their weekly earnings would be as follows,

Rico:
       750 + 0.05x


Sean: 
      1100 + 0.025x

 Equating both expressions,

     750 + 0.05x = 1100 + 0.025x

Simplifying,
      0.025x = 350

The value of x from the equation is 14000.

Answer: $14,000.
