Answer:
21 hours
Step-by-step explanation:
You and your friend swam for 10 hours then took a break then swam for 11 so 10+11=21 so you and your friend swam for 21 hours all together.
Just divide 4.5 by 2.8 and you'll get the rate of decreasing degree per hour.
Annually: Total Amount= $1,611.76 Interest Amount= $711.76
Semiannually: Total Amount= $1,625.50 Interest Amount= $725.50
Quarterly: Total Amount= $1,632.62 Interest Amount= $732.62

Answer:
1,041.9feet
Step-by-step explanation:
Given the height of the rocket expressed as
y = -16x² + 245x + 104
At maximum height, dy/dx = 0
dy/dx = -32x+245
0 = -32x+245
32x = 245
x = 245/32
x = 7.65625
Get the maximum height
Recall that;
y = -16x² + 245x + 104
Substitute the value of x;
y = -16(7.65625)² + 245(7.65625) + 104
y = -937.890625 + 1,875.78125 + 104
y = 1,041.890625feet
Hcne the maximum height to the nearest foot is 1,041.9feet
